The Best Leafy Greens List

By: Jen Hansard | last Updated: 3.29.2013 | COMMENTS: 628

The shining stars of green smoothies are the leafy greens— chock full of phytonutrients, protein, vitamins, antioxidants…the list goes on and on. Yet there is also something you need to be aware of when drinking green smoothies daily— it’s called “alkaloid buildup.”

We made a best leafy greens list below, but first…

All raw leafy greens carry a small amount of toxins that protect plants from being entirely consumed by other animals—and wiping out the plant species. It’s a defensive trait, and something even we should be aware of. As humans, if we consume these toxins for long periods of time, they can build up and harm our thyroid. Some symptoms of alkaloid buildup are nausea, tingling in fingertips and fatigue.

But before you dump your green smoothie down the drain, you should know that this isn’t anything to worry about as long as you are rotating your greens. Use a variety of leafy greens in your smoothies— like kale, spinach, chard (silverbeet), romaine and other lettuces, herbs, and carrot tops.

spinach leafy greens

“I’m freaking out! I only use spinach!”

Do you, or someone you know, eat the same leafy greens in your salad day after day? There’s no big news stories about people eating the same salad everyday and getting sick. It seems like so many people try to create so much controversy and scare tactics around green smoothies and healthy eating in general.

Try not to sweat rotating your leafy greens so much. Your body is wise enough to let you know when it’s time to change things up.

So, just a reminder, alkaloid build-up is rare. And if you do experience any symptoms, they’re very mild and they don’t last long. Nothing that will send you to the doctor’s office. You might just take a few days break from green smoothies and jump right back in!

But I know people ask this question a lot, so here’s a guideline if you really want to rotate your greens like a rawkstar…

How often should you rotate greens?

Start out with rotating your leafy greens weekly. So one week you might buy spinach, and then on your next shopping trip, you might buy kale.

There are several “families” of leafy greens. The leafy greens in each family have similar “DNA” including their own minor amount of toxins. By rotating family types with your greens you are preventing any kind of toxic build-up, but you are also feeding your body a wide variety of nutrients that you would otherwise be missing out on.

leafy greens variety

Your leafy greens list:

To help keep you slurping your smoothies we made a list of our favorite greens (there are way more leafy greens than the ones we listed below) and separated them into family groups so you can easily rotate!



If you like spinach then you will like kale. They are both known for their wide variety of nutrients, mild taste, and availability in your local markets. The best part is that they are from different families, which will make rotating a breeze. Having any kind of health issue? Kale will probably help, though they are especially talented at fighting cancer. Click here to blend this kale smoothie.


Collard Greens

Like their other cruciferous family members, collard greens are great cancer fighters. They are also pretty good at helping your body digest foods properly with all the fiber inside. They are most popular as a steamed leafy green, but adding them raw to your smoothies will provide you with more health benefits because they lose nutrients when cooked. Try this collard greens smoothie recipe right here.


Cabbage is yet another example of a cruciferous cancer fighting leafy green. One thing that may help to separate it from the pack is its popularity in home gardens and fresh markets, which makes them easy to find. It also has a hint of sweetness to go with those yummy, summer smoothies filled with berries. Try this cabbage smoothie right here.



Its hard to beat spinach when talking about nutrient packed greens. Just one leaf contains a sampling of more than 20 different nutrients. The list of benefits is nearly as long as the amount of nutrients: cancer fighting, blood pressure beating, bone strengthening, cardiovascular helping, brain boosting, skin smoothing, vision improving, inflammation reducing, energy increasing, and more. Spinach is a green smoothie staple for all! Click here to blend this spinach smoothie.


Beet Greens
When was the last time you ate beets, let alone the leafy greens on top of them? We recommend branching out and trying beet greens for your next smoothie! They include a wide variety of nutrients, but make their claim to fame with tryptophan. Tryptophan is the culprit of all those Thanksgiving Day naps, but more importantly helps with better sleep cycles. If you are always complaining about being tired, don’t turn to coffee. Add tryptophan to your green smoothie. Click here to blend this beet smoothie.


Chard is a colorful leaf best known for its ability to regulate the body’s blood sugar system. Translation? If you have diabetes or struggle to main your blood sugar levels then chard should become a regular part of your leafy greens rotation. Try it in the morning to start your day off right! Click here to blend this chard green smoothie.



Dandelion Greens
Looking for calcium without the cows? You got it! A healthy dose of dandelion greens will give you near the same amount of calcium as a glass of milk will, but it will also fill you with other nutrients that milk doesn’t. When using them don’t forget this saying, “A banana in the blender kisses the bitter good-bye!” Click here to blend this dandelion greens smoothie.


Romaine Lettuce
Romaine lettuce is a nutrient rich leafy green that is good for your heart and low in calories. The vitamin C and beta-carotene content help to lower cholesterol and prevent build up on artery walls, which reduces the risk of heart attack. Being low in calories also helps you lose weight while keeping you full. Click here for this romaine smoothie bowl recipe.



Ever heard of phytonutrients? They are what makes celery stand out among other raw greens. Phytonutrients are an antioxidant that help prevent damage done to body fat and blood vessel walls. This may not sound important, but to put it in common terms blood vessel damage leads to many of the diseases we see today. Be sure to use strong fruit to balance out the potent flavor of the celery stalks and/or leaves. Click here to blend this celery green smoothie.


Most fast food is dipped, cooked, and lathered in all sorts of unhealthy things that cause high blood sugar and cholesterol, but not this “fast food.” One of the remedies for lowering blood sugar and cholesterol is cilantro, and its fast and easy to add to your daily smoothie! Try it with lime juice and other tropical treats. Click here to blend this cilantro green smoothie.


Carrot Tops
Carrot tops are filled with chlorophyll, which has been shown to fight against tumor growth and acts as a cleansing agent. The best way to buy carrot tops is to buy carrots with full greens on top. You will have nutrient filled green smoothies and a snack for later. Click here to blend this carrot tops green smoothie.

Rotating your greens is easy and fun! When you rotate you getting access to many different kinds of nutrients that each raw green has to offer, but at the same time you are preventing alkaloid build-up.

When rotating, keep in mind to go from family to family. You may have to experiment with a few different greens from each family to find out what you like, and what has the best benefits for you, but the benefits are worth it! Once you know what you like you can find staple recipes that go well with each green.

Rotating is good for you, keeps things fresh, and simple.

    I like spinach or kale. I need to try the Dandelion greens!

    • SGS Rawkstar Jess says:

      Sonya, def give the dandelion greens a try! And don’t forget a banana to balance out the slightly bitter taste of the greens. 😉 Let us know what you think after you try them!

  2. Dawn says:

    Can I use Bok Choy as the green in a smoothie?

    • SGS Rawkstar Jess says:

      Hey Dawn! You can definitely use bok choy in your smoothies. It has a mild taste, similar to cabbage so keep that in mind when deciding which fruits to mix in (I might use fruits that are on the sweeter-tasting side).

  3. Jason R Cox says:

    I am thinking of growing cardoon. What do you think?

  4. Lori says:

    I always like to use spinach + kale or spinach + power greens in my smoothie. I buy it in bags. In a pinch, i.e. I’m out of bagged greens, I forage from the “weed patch”, a.k.a. my yard and get wild dandelion, plantain, herbs, violet leaves, whatever.

    • SGS Rawkstar Jess says:

      Lori, I love that you forage in your backyard! There’s so much good stuff out there that most of us call “weeds” and it’s great that you take advantage of what’s right outside your door. 🙂

  5. Michelle Fox says:

    How do I fine smoothies that use each of these greens? Do you just substitute for whatever greens you are eating that week? Also, do you have recipes for smoothies that “flip the ratio” as you mentioned to have more greens than fruit?


    • SGS Rawkstar Amanda says:

      Hey Michelle,

      Most of our recipes you can swap the greens for whatever you have on hand or to keep up your rotation. Also we do not have specific recipes for the “flip ratio” because you can use that with any recipe we have. We like to keep our recipes easy and versatile. All you have to do is find a recipe you like and simply switch the fruits and veggies amount and your smoothie will be “less sweet”.

      Hope that helps!

  6. Flo says:

    Hi wow very helpful tips. Love juicing. Just learnt from a friend that she adds amaranth leaves to her smoothies! I didn’t know that.

    Do you have recipes?

    • SGS Rawkstar Amanda says:

      Hi Flo,

      While we don’t have any recipes with amaranth leaves (yet!), don’t let that stop you! Our recipes are here to inspire you, so don’t hesitate to change it up + try adding amaranth leaves to any of our recipes!

  7. Rophina Atanga says:

    7 simple is great

  8. Al F says:

    One of the best investments that I have made was in a Vitamix blender! I’m loving mine every morning to make my green smoothie. There are other great blenders on the market as well. To our health!

    • SGS Rawkstar Amanda says:

      Hi Al,

      We love Vitamix too! Nothing beats a powerful multi-purpose blender!

      • Deborah Korch says:

        I also just bought a Vitamix. It’s powerful and slightly freaks me out. I now can safely get rid of my other 2 juicers that also won the intimidation game.

      • SGS Rawkstar Carissa says:

        Hey Deborah,

        That is so exciting!!! I bet you are loving it already. It can be really intimidating though so I definitely get that. Pretty soon it will feel like second nature and that you’ve had it forever 🙂

  9. Keeny says:

    I am doing a 10 day green smoothie cleanse. I use a power blend of greens (chard, spinach and kale) everyday. Is this a bad idea?

    • SGS Rawkstar Amanda says:

      Hi Keeny,

      Worried about oxalate build-up while using your power blend? Try not to sweat rotating your leafy greens so much. Your body is wise enough to let you know when it’s time to change things up.

      Just a reminder, alkaloid build-up is rare. And if you do experience any symptoms, they’re very mild and they don’t last long. Nothing that will send you to the doctor’s office. You might just take a few days break from green smoothies and jump right back in!

  10. Yvonne Scott says:

    Hi, I am overweight and had high blood pressure. My friend and I decided to lose weight together. She lives in NY and I live in Florida. She turned me on to smoothies, but mostly fruits. I was using an orange, an apple, a banana, strawberries and blueberries and coconut water. I was losing weight, but then I gained 3 lbs! I spoke to my dr and asked how that was possible? Whammo, he said I was consuming way too much sugar from all that fruit. So, I began to stop the fruit smoothies and moved to kale, spinach, celery, carrot and threw in some frozen strawberries and a handful of frozen blueberries. For liquid I use coconut water with no added sugars or fruit. Now, the last 2 dr visits were particular, when I asked about my pressure IT WAS SO MUCH LOWER, the first time I figured it was just a fluke, but when it happened again at a different dr I WAS STYMIED. Why was my pressure changing (I never took pressure meds) then it hit me…THE GREENS! I couldn’t believe I actually was doing something that made such a healthy difference. However, I’ve been using the same ingredients for a month now and I just bought another giant bag of both kale and spinach. How am I doing? How can I incorporate other greens, and is broccoli thrown in raw…just florets? What about the leafy green part of celery, I have been tossing it in the garbage. PS I throw in some Bobs Redmill unmodified potato starch or a green unripened banana for resistance starch. What am I doing right and what am I doing wrong? Thanks for your knowledge, it is appreciated, Yvonne

    • SGS Rawkstar Amanda says:

  11. Mel Mohan says:

    I started doing green smoothies in the summer of 2015 I had them everyday twice a day. In February I was at the doctor with kidney stones due to high oxalate build up. I was advised to lay off the green smoothies for awhile (which was very hard for me as I loved the energy it gave me) and am just getting back into them. I want to rotate my greens, but am not really sure what to mix with each type of green for optimal flavour…..any suggestions?

    • SGS Rawkstar says:

      Hi Mel,

      Variety is the fruit of life! I love switching up my leafy greens. So while one of our recipes may call for spinach, change it up + try it with chard or kale! Don’t hesitate to experiment.

  12. Rachelkaren says:

    What can I mix with greens in a smoothie that will overpower the green coloring? My husband will not drink “anything green”

    • SGS Rawkstar says:

      Hi Rachel,

      Husband not a fan of that green color? We’ve got you covered! Add in beets or dark berries for a red or purple color! Here’s one of our favorite “purple” green smoothies we think he’ll love…


  13. Sean K. says:

    Thank you for this website! I started drinking a green smoothie for breakfast about a month ago and so far its the best dietary change I’ve made (27 y/o male with limited cooking skills but great ordering out skills).
    I have 2 questions for you,

    1. I have been using a green powder (Amazing Grass Green Superfood) but now I’m worried of Oxalate build up from the mix of the same greens daily. Do these powders contain oxalate?

    2. I workout in the morning and like to add a scoop of protein to my smoothie, do you have any recommendations for protein packed smoothies? I use plant-based protein blends but now I’m worried about rotating them (typically quinoa, hemp, pea, chia blend).

    • SGS Rawkstar says:

      Hi Sean,

      YAY!! We’re so excited to have you blending with us + love hearing that you feel green smoothies is the best dietary change you’ve made!! We’re blushing!

      Worried about oxalate build-up in green powder? Because they’re processed, I would assume that some of the oxalates have been broken down. But it’s always best to reach out to the company behind your favorite powdered greens, as it may vary based on how they’re processed.

      Looking for some protein packed green smoothies? Here are a few of our favorites…




      We also love this plant-based protein from The Nautral Citizen. Check them out here…


      Also, worried about rotating your plant-based proteins? We always support variety. It protects your body from build-up, but also ensures you’re fueling your body with a wide-range of nutrients.

  14. Lyndsey Russell says:

    Could you choose 2 veggies (1 each from a different family i.e. one week kale and chard then the next week spinach and cabbage) to put in or would you only recommend 1 each time? I ask as my favourite smoothie has spinach, kale, broccoli, celery, mango and pineapple and I’ve had this everyday for about 2 weeks now but I’m worried about the poisoning thing

    • SGS Rawkstar says:

      Hi Lyndsey,

      You definitely could! We love mixing up our leafy greens. We simply suggest taking a week off from a specific family of greens. For example…blend crucifers and apiaceae this week, then next week blend up amaranth and asteraceae. Also, everyone’s body is different and has different sensitivities to oxalate build-up. So it’s always important to listen to your body when determining how often to rotate your greens.

  15. Ed says:

    I’ve been using spinach as my staple ingredient for green smoothies twice a day (for 2 years now)

    I tend to rotate the other ingredients such as Broccoli, Kale, Celery twice a day (morning I might toss in Broccoli and at night I’ll toss in Kale and Celery)

    It has been working for me since, no doctor visits or anything!

    • SGS Rawkstar says:

      Hi Ed,

      YAY! We love changing up our veggies + leafy greens. We’ve also found that oxalate sensitivity is different for everyone.

  16. Beverley says:

    I wash all my fruits and veg in vinegar to get rid of toxins.. is this ok?

    • SGS Rawkstar says:

      Hi Beverly,

      Washing your greens with vinegar and water is a great way to remove bacteria and pesticides from your leafy greens. But it’s still important to rotate your greens, to prevent toxin build-up from the natural toxins that occur within the plant.

  17. Mum 3.0 says:

    I tried carrot tops, say with pears and some apple juice, but they do not mix well when I put everything together in the blender. Do you have any tip for these tops?
    Thank you!

    • Jackie says:

      I would use a cheese cloth to strain it, I have a Vita-mix, and I start off putting my green leafy greens first with liquid. Next step the fruit, preferably frozen. I would not dump my ingredients in the blender at once.

    • SGS Rawkstar says:

      Hi Mum 3.0,

      Have you tried blending the carrot tops + liquid base first? Then add your remaining ingredients. Check out blending your green smoothie without any leafy chunks here!


  18. Jana says:

    1. What are ur thoughts about using green powder product instead of raw greens if no access to fresh produce?
    2. What’s the 411 re spinach not allowing body to absorb calcium? I want to increase calcium intake to build bone density & not sure if spinach should be eaten separately from calcium-rich foods or if that’s false. Thx!

    • SGS Rawkstar says:

      Hi Jana,

      Personally, we’re all about fresh leafy greens. But when raw greens aren’t accessible, green powder is a great option! Worried about spinach preventing calcium absorption? While oxalates prevent calcium absorption from spinach, we reach for plant-based options like broccoli, okra, + almonds.

  19. Nd says:

    If all leafy greens have a small amount of toxins, how does rotating help? It seems that Oxalate build-up would still occur unless you completely refrain from leafy veggies for a few days or week. Someone previously ask if cooking the veggies helps reduce or prevent toxin build-up, but the question wasn’t really answered. Instead, rotating veggies was again recommended. Months ago Dr. Oz recommended only consuming raw leafy green veggies 2-3 times a week. He advised to cook veggies slightly beforehand if you consume daily. Have you researched this option? If so, do you feel there is significant nutrient lost if you lightly steam veggies? Thanks!

    • SGS Rawkstar says:

      Hi Nd,

      Great questions! The leafy greens in each family have similar “DNA,” each including their own minor level of toxins. By rotating family types of leafy greens you’re not only preventing a toxic build-up, you are also feeding your body a variety of nutrients. Therefore it’s not necessary to take a break from leafy greens, but simply rotate between greens.

      We prefer to get our veggies raw to obtain the maximum nutrients and they make our smoothies super yummy. But if you want to cook your greens before blending to help further prevent toxin build-up, a light steam will help!

      Hope this helps!

  20. Lucy Khan says:

    How much spinach or Kale should I add to smoothie? 1-2 cups of spinach? Is that too much?

    • SGS Rawkstar Jen says:

      That’s perfect! We recommend 1 cup leafy greens for 1 serving of smoothie— and our recipes typically make 2 servings (so we say 2 cups leafy greens). Make sure to check out our recipes section where you’ll find a bunch of recipes to get you started!

  21. John says:

    I have been doing green smoothies for almost 4 years now. These are amazing things I drink a quart in the morning and a quart in the evening. Same thing every day. Spinach, Kale, chard, flax seeds, sun flower seeds, chia seeds, avocado, and tofu. I can’t eat sugars or carbs except for what is in the nuts and seeds I eat. after reading your article I have decided to start rotating my vegetables not because of any problems from eating the same thing every day but to get the extra nutrients that this will give me.

  22. Dawn says:

    seems everytime I make a smoothies of kahl spinach and other greens I have a verigo attack and heart starts beating

    • SGS Rawkstar says:

      Hi Dawn,

      Ek! That doesn’t sound good. And we definitely want you feeling great when enjoying your green smoothie. We suggest reaching out to your physician to ensure the leafy greens in our recipes are the right choice for you + your body.

  24. Wendy says:

    Hi I know that fresh is best but can I use canned fruit instead when I can’t get freash.

    • SGS Rawkstar says:

      Hi Wendy,

      That’s a question we get a lot. You can definitely used canned fruit. But, it’s important to know that when using canned fruit, even those stored in their own juice, contain additional sugar. So reach for low-glycemic fruits like berries, apple, or peaches.


      We love reaching for frozen fruit when our favorites are out of season. Or check out our Rawkstar Substitution Guide…


  25. Ashley says:

    I am new to this and was wondering, when switching up greens, can I go from spinach, kale and romaine lettuce? Spinach in a smoothie for breakfast, kale for lunch and the romaine lettuce at dinner? Or do I need to switch each week?

    • SGS Rawkstar says:

      Hi Ashley,

      Thanks for reaching out. We suggest switching leafy greens week to week. That way it gives your body plenty of time-off between each green.

  27. Ada says:

    I have been drinking a green smoothie monday to friday for over two months now.
    What I normally put in it is:
    – One or One and a half hand fulls of Spinach
    – One or One and a half hand fulls of Kale
    – A small bannana or half of a big one OR Half of a big apple
    – Hand full of strawberries OR Blueberries
    – Sometimes a bit of celery Or Cucumber Or half of an orange

    I do this as I find the smothie is very easy breakfast on the go, and it keeps me satisfied by at leas 3 hours..
    My question is…
    Will I get that Alcaloid Build up if I continue doing this?
    How much is too much leafy greens?
    Should I rotate one day just spinach and another day just kale? Will this prevent it?

    Ada S.

    Thank you

    • SGS Rawkstar says:

      Hi Ada,

      Your smoothie sounds awesome! Worried about oxalate buildup? Simply switch up your leafy greens week to week. For example blend kale one week and the next week spinach, then blend kale the following week. This will give your body enough time to prevent any toxins from building up.

      Hope this helps!

  28. Joyce Pearson says:

    What are the symptoms of greens toxicity build up? I believe that’s what you called it. And is it possible to get it from the over consumption of any greens? I’m new to smoothies and looking forward to some new and awesome tasting smoothies. Also what are vegetables that can be added? Frozen carrots, peas, mushrooms? Just curious. Thanks for all your love and

    • SGS Rawkstar says:

      Hi Joyce,

      Thanks for reaching out. All raw leafy greens carry a small amount of toxins that protect plants from being entirely consumed by other animals—and wiping out the plant species. It’s a defensive trait, and something even we should be aware of. But if we rotate our greens we help prevent this build-up. Some symptoms of oxalate build up can be joint pain, kidney stones, or hives.

      You can definitely add veggies to your green smoothies! We especially love blendin’ with root vegetables. Learn more about our favorites here…

    Greetings!! How do I know which greens go with what fruit…like do raspberries and arugula compliment one another? How do I know which greens best suit which recipe?

      Hi Shavonne,

      Know what’s great about our green smoothie formula!?! The ratio of fruit to leafy greens allows you to get really creative, without being overpowered by that “green” flavor, no matter what leafy green you’re blendin’ with.

    I’m new to your website. Your recipes look yummy, but I am pre-diabetic with orders to keep my smoothies low in sugar content where your recipes are high. I’ve been doing my own thing with smoothies, using only strawberries and cucumbers to enhance flavors, but honestly, the totally green flavor gets old. Is there a happy medium that would taste yummy but keep the sugars low?

    • SGS Rawkstar says:

      Hi Nillawilla,

      Thank for reaching out to us. Since we are not doctors or nutritionists, we suggest that any member of community with health concerns to speak to their healthcare provider to confirm that green smoothies and the natural sugars are okay for their eating plan.

  33. Ann says:

    I have read about the amazing benefits of wheatgrass. I just bought some and want to put them into my smoothies. But was wondering if adding the wheatgrass to the greens already called for in the smoothies would be too much greens. The serving size for the wheatgrass I have is 1/4 teaspoon.

    • SGS Rawkstar says:

      Hi Ann!

      Totally up to you! You can absolutely add wheatgrass to your smoothies :). You may just have to experiment with the amount to find what tastes best for you.


  34. Ann says:

    Hi, I am new to “Rawkstar. I have a question: I buy the pre-package of “Super Greens” that contain at least 3 different greens. The package I have now is Trader Joes “Power to the Greens” which is baby kale, baby chard and baby spinach, all organic. I usually add parsley and cilantro to them, but the next package I buy will probably have different greens. ie: spinach, bok choy and mustard greens. So, am I already rotating my greens?

    • SGS Rawkstar says:

      Hi Ann,

      Great question! And we love Trader Joe’s mixed greens too! As long as you’re changing up your greens, and giving your body a break between weeks (ex. taking week off from kale, and then starting back up the following week), then you’re rawkin’ it!!


  35. Claire says:

    Are there more greens for “APIACEAE” group?

    • SGS Rawkstar says:

      Hi Claire,

      Thanks for reaching out! Looking for more asteraceae options? Try reaching for lettuce, chicory, or endive!


  36. Iva says:

    Unfortunately I have gastritis and colitis. I have been drinking green smoothies for a week instead of breakfast, but I got a strong stomach pain. Can you tell me how to add green leafy vegetables in my smoothies to have no pain? I’m worried by the formation of oxalate kidney stones, as I am inclined to form such. What would you advise me?

    • SGS Rawkstar says:

      Hi Iva,

      We’re green smoothie lovin’ rawkstars alright, but not doctors or nutritionists – we suggest you talk with your doctor about any health concerns— I’m sure they can help you decide what is best for you and your body.

      Cheers to health + happiness!

    • Alex E Smith says:

      Add ginger to your smoothie. It soothes the stomach

    • Tamara says:


      I have colitis, also, and my doc put me on a Low FODMAP eating plan due to my body’s reaction to some foods. It’s how your body MAY be not digesting certain sugars.


      Peel some ginger and add pineapple to most of your smoothies for anti-inflammatory and tummy soothing properties.

      Hope this helps!

  37. Claire says:

    I appreciate your information.
    I keep trying the cycle what you told.
    I’ve been drinking my green smoothies for 3 weeks now, and it was fine until yesterday.
    Regarding “ASTERACEAE”, there are only two types of greens and it’s very tough for me to find.
    First, the dandelion greens are difficult for me to find. (I’m living in the city of Seoul in Korea, and it’s not a popular green.)
    Also, its taste is very strong for me. (I don’t think it is 100% same dandelion green with U.S’s.). I have also added some fruits. I don’t want to eat only romaine lettuce when I’m taking “ASTERACEAE” greens.
    I also want to stick to the cycle that you mentioned. Are there any more greens in “ASTERACEAE”?
    If so, please let me know. Or, can you please give me any advice?

    • SGS Rawkstar says:

      Hi Claire,

      Thanks for reaching out! Looking for more asteraceae options? Try reaching for lettuce, chicory, or endive. Also, if you’re in Seoul, feel free to reach for greens that are local to your area!


  38. Lynn says:

    I was on week 8 of green smoothies meal replacement for breakfast…spinach..pineapple..mango…banana, coconut oil and plant based protein powder. I felt great!!! …salads for lunch and a regular balanced dinner. I was nauseated for a couple of days and then had diarrhea for 12 days. I ended up at the doctors who told me to cut them for 3 weeks and go on the brat diet. I wondered about not rotating greens or if I had contaminated produce. I was back to normal and just went back on and rotated to Kale. However..I am using the same mango, pineapple and banana that I had cut up and froze from when I was sick. I was nauseated while drinking my first one yesterday….and vomitted today after the second sip. Can’t figure out what is doing it. A food allergy? The protein powder? No rash or anything else. Is there one ingredient that would be more likely to cause an allergy or digestive issue?

    • SGS Rawkstar says:

      Hi Lynn,

      Oh no! We’re so sorry to hear you’re not feeling well. It’s definitely important to review your ingredients and ensure you don’t have a food allergy or intolerance. Because we’re green smoothie lovin’ rawkstars, but not doctors or nutritionists – we suggest you talk with your doctor about any health concerns— I’m sure they can help you decide what is best for you and your body.

      Cheers to health + happiness!

  39. Yemima says:

    Hello! It is fun to read your web.
    One thing that I’d like to ask, do we have to boil or maybe steam the veggies first before we make smoothies? Because, you know, I once read and being told that eat raw food everyday can cause toxo. This is like a bad news because I want to consume green smoothies everyday. Thank you!

    • SGS Rawkstar says:

      Hi Yemima,

      Thank you so much for reaching out! You’re right, all raw leafy greens carry a small amount of toxins that protect plants from being entirely consumed by other animals—and wiping out the plant species. It’s a defensive trait, and something even we should be aware of.

      We love consuming our leafy greens raw, and for that reason we suggest rotating your leafy greens. This will prevent those small toxins from building up and negatively affecting your body.

      Hope this helps!

  40. Amy DeBruyn says:

    We’ve been using the Earthbound Farms Power Greens (baby kale, chard, and spinach) for-just-about-ever… I had never heard about rotating greens. My husband and I each drink a smoothie every morning that has 2-3 cups of these greens. Since these greens are from different greens families, would you say we need to break from this product? Great site – thanks for the info!

    • SGS Rawkstar says:

      Hi Amy,

      We’re all about variety here at Simple Green Smoothies. Rotating your greens allows your body to benefit from a wide arrange of nutrients, and helps prevent oxalate build-up. But no need to break up with your power greens. Simply take a week off, blend a different combination, and then add them back to your smoothie the following week.


  41. Johnny says:

    I really appreciate the information on the website and I have been extracting and blending green smoothies for a week now and I have been using Baby Kale about 2 cups, 1 whole Banana, 1 cup of frozen pineapple chunks, 1 cup of Almond milk unsweeten, and 1 cup of Blended juice orange, pineapple, and banana juice. and next week I’m going to buy Spinach and substitute it for the kale. I’m drinking a 32 oz Green Smoothie twice a day I have not lost any weight yet but I am hoping to soon. What do you think about my Green Smoothie Recipe I am currently using?

    • SGS Rawkstar says:

      Hi Johnny,

      Thank you so much for reaching out. We’re so excited to have you blendin’ with us! Your recipe sounds awesome! Are you using your green smoothies as a meal replacement to meet your weight loss goals? If so, we suggest adding protein + healthy fats to ensure your’e fueling your body with a complete meal.

      Do note that all of our recipes make two (16oz) servings. We suggest sticking between one to two servings per day to help fuel your body.

  42. Cindy says:

    Hi Jen and Jadah,
    I have been juicing with you for a few months now. I was wondering if I really have to substitute my spinach if I am eating romaine lettuce in salads every day and having cilantro in some of my smoothies? I just love the spinach so much. I find romaine and a few other greens very bitter in a smoothie.
    🙂 Cindy

    • SGS Rawkstar says:

      Hi Cindy,

      Great question! Even if you’re fueling your body with different greens it’s important to give your body a break from the nutrients in one specific leafy green to prevent build-up. That’s why we suggest taking a week off and adding a different green to your recipes. Finding a few greens too bitter? Try reaching for baby greens! They’re packed with the same nutrients as their mature counterparts, but with a milder flavor!

  43. Mary Lou says:

    Hi! Having good luck with the green smoothies but find spinach is giving me black stools. What gives with that?

    • SGS Rawkstar says:

      Hi Mary,

      Thanks for reaching out! Spinach is packed with iron, which can cause a change in color. Concerned? As we’re not doctors or nutritionists we suggest reaching out to your physician to ensure our recipes + ingredients are the right choice for you + your body.


  44. Miki says:

    Here’s another question I’ve been meaning to ask. When measuring greens, is it one cup (or whatever) packed, loose, or medium?

    • SGS Rawkstar says:

      Hi Miki,

      Great question! We tightly pack our leafy greens! Want to see how Jadah + Jen measure their greens? Check out this video of them blending here…


  45. Miki says:

    InI like the idea of the rotations! To implement this in your smoothie recipes, would I swap out the spinach or kale for another green in the same family?

    • SGS Rawkstar says:

      Hi Miki,

      Thanks for reaching out! When rotating your leafy greens we suggest switching between leafy green families. For example, love spinach + kale? Blend spinach one week, then the following week take the week off spinach and blend kale instead. Rotating kale + spinach is a great option because they’re both mild in flavor but from separate leafy green families!


  46. Antonia says:

    Hi, I am relatively new to the green smoothies and have been having them for my breakfast for the last month and loving it. I have been using kale and spinach. Do you recommed using both of those together in a smoothie or should one week I use kale with something else then the next spinach with something else?

    Thanks x

    • SGS Rawkstar says:

      Hi Antonia,

      We’re so excited to have you blendin’ with us! We love combining our leafy greens, so blending kale + spinach together is a great idea. When it comes to rotating your greens, it is important to give your body a break to help prevent oxalate build-up. So if you enjoy blending kale + spinach together, try blending a different combination the following week, and then blend kale + spinach again.

      Hope this helps!

  47. sally says:

    Might sound like a silly question but rather than rotate the greens, can you just use a variety of different greens in one smoothie but less of them?

    So rather than 1 week kale one week spinach, one week romaine, have all three everyday for 3 weeks but 1/3 of each?

    • SGS Rawkstar says:

      Hi Sally,

      Not a silly question at all! The reason we suggest rotating your greens is you’re giving your body a quick break from the nutrients of a specific green family. That week off allows your body to absorb different nutrients + prevent oxalate build-up. While we love blending with different greens, doing so each day without a break can still put you + your body at risk of build-up.

      Hope that helps answer your question!

  48. ruby says:

    Hey im pretty new at green smoothies i currently only uses spinach and one tbs of flexseeds, but I’m an extreme anemia, vitamin b deficient,vitamin d deficient and i don’t drink milk anymore so what should I be adding to my smoothies in order to get all the nutritional i need
    I don’t want to turn to supplement. Thanks

    • SGS Rawkstar says:

      Hi Ruby,

      Thanks for reaching out! We’re green smoothie lovin’ rawkstars all right, but we’re not doctors or nutritionists. We suggest you talk with your doctor about any health concerns. If your physician suggests adding specific ingredients to your diet to help combat your anemia + vitamins deficiencies, we’d be happy to point you in the right direction!

      Cheers 🙂

  49. Ann says:

    Thank you for this information. I have been using only spinach and kale. I will try all the others that is mentioned above. It will be a challenge………..Ann

    • SGS Rawkstar says:

      Hi Ann!

      You’re so welcome :). Spinach and kale are my go-to greens, as well, but the others really are a nice change! When you rotate your greens, not only do you prevent oxalate build-up, but you’re also giving your body some different nutrients. It’s a win-win!

  50. Nikki says:

    Is it more beneficial to rotate greens from one family to the next week to week, or get both in one week? I usually have a green every night in my smoothie, and I was wondering if it would be better to do a week of kale, then a week of chard/spinach, or do a week where I switch back and forth every day. This is a really thought- provoking article, thank you for this!

    • SGS Rawkstar says:

      Hi Nikki,

      Great question! We suggest rotating week to week. That way you’re giving your body a whole week off from one leafy green family to help prevent oxalate build-up.

      Hope this helps!

  51. Anne Kingston says:

    Thank for all inspiration. Have been doing my 2 a day since last oktober – I was sas in the challenge. Since organic leafy greens are hard to come buy in Sweden for several months during winter (I refuse to count such flewn in as organic) I mostly lean to cabbage and broccoli the last months. But it’s hard to figure out the equivalent to 2 packed cups leafy greens. Do you have a weight measure to use?

    I will now make sure I rotate my greens
    Also what is your opinion on these super greens mix sachets, mix of wheatgrass, barley grass spirulina etc..i think you add 5g or so to your smoothie
    Just thinking on lazy days!! any good? also what about protein powders do you use those?

    My daughter who is 12 and I found this website after she heard her teacher and I heard my boss speak of green smoothies now for months straight. This is only our forth week but we are addicted. We love trying new fruit and greens combos every day and it gives us that one on one big of togetherness every day. We have started being cautious of everything we put into our bodies now and even go do the gym 3-4 times a week. I can already feel a difference in my energy and body is craving more and more healthy food which I love. Thanks for all you share its AWESOME!

  56. Nikola says:

    Hey guys,
    I LOVE your website! have already participated in two challenges; and this time it stuck! I am really craving those green bastards, if I don’t get my daily smoothie every day I truly miss it. Today I tried arugula instead of the ol’ spinach and kale routine – just because, where I live, I don’t always easily come by fresh spinach or kale. Using the frozen product was somewhat underwhelming, so I tried arugula from my local supermarket – turns out it is AWESOME, pardon, RAWKSOME! :-)))

  57. stephanie scott says:

    Hi there,
    I see that cilantro belongs to the apiaceae group. What about
    Parsley, mint and basil? I want to rotate them, correctly.


    • SGS Rawkstar says:

      Hi Stephanie,

      Great question! Parsley is also part of the apiaceae family, while mint and basil are part of the lamiaceae family.

      Hope this helps!

      Cheers 🙂

    Thanks for the fabulous information on rotating greens families. My son (13) and I (52) are now blending (Ninja Smoothie Maker) various fruits and veg for weight control & health benefits.

      Hi Dubsteppa,

      We’re so excited to have you + your son blending with us! Looking to lower the natural sugar content of recipes, try turning our Simple Green Smoothie Formula on it’s head! Instead of blending 3 cups fruit with 2 cups leafy greens, try blending 2 cups fruit with 3 cups leafy greens.

      Or swap in a low sugar fruit!

  59. RC GOLFER says:

    I bought myself a Blendtec for Christmas, and I’ve been blending and checking out and enjoying your site ever since. I think I may not be rotating correctly. I’ve been blending two different families daily, and drinking those two families for the whole week, then I go to two different families daily for a week. Do you think it’s better to blend one type for half the week, switching to another type for the rest of the week? As an example, this week I’m using a kale/spinach blend daily. Is it better to go with kale only for a few days, then switch to spinach only for the next few days? Thanks!

    • SGS Rawkstar says:

      Hi RC,

      It sounds like you’re blending perfectly! As long as you’re taking time off (ex. a week) from a specific family of greens you’re giving your body the chance to reset and prevent oxalate buildup.

      Cheers 🙂

  60. Bobbie says:

    I have been a fan of green smoothie’s for over 3 years now, and have drunk one, vitamix size, of spinach, kale, cabbage and 4 different fruits faithfully for my lunch alone for these 3 years. I had
    no idea about rotating greens. All I know is that I started to have serious hair loss, itching all over my body, edema in my feet, and
    high cholesterol. I have always had thick, thick hair and normal cholesterol. Come to find out I have chronic Vit A. toxicity. I have
    completely stopped drinking these and hope my hair and these problems will resolve. I am vegan and never dreamed I was doing something to hurt my body.

    • SGS Rawkstar says:

      Hi Bobbie,

      So scary. We agree it’s hard to believe that something so good for you, could potentially effect your body negatively.

    • Saskia says:

      Oh that sounds delicious!

    • SGS Rawkstar says:

      Hi Sophie,

      We love using a variety of leafy greens, and that combination sounds out of this world! We do suggest continuing to rotate your greens, for example take a week off of spinach, and then the following week remove a different type of leafy green. So your body is being fueled by different nutrients and you lower your risk of oxalate buildup.

      Hope this helps!

    Hi. I’m new to smoothies and just found your website! I am the mind of person who does not like to experiment, when I find the one I like I want to stick with it. Wondering, would it work to mix a nice variety of greens instead of rotating greens? Or is it better to rotate?

    • SGS Rawkstar says:

      Hi Denise,

      Great question! While we love using a variety of greens, we do suggest rotating from week to week to prevent oxalate buildup and fuel your body with different nutrients.

  72. Lyn says:

    Hi love your site my husband and I just started the green smoothie plan and although I don’t have diabetes I notice after drinking the smoothie my sugar does shoot up is this normal I really like getting up first thing in the morning and drinking a refreshing drink just don’t like the raised sugar problem thank you any ideas???

    • SGS Rawkstar says:

      Hi Lyn,

      Thanks for blendin’ with us! Concerned about the natural sugar content in our recipes? Each smoothie has 3 cups of fruit in it, and it is recommended that an adult has 1.5 to 2 cups of fruit a day. When you drink 16oz of our green smoothie recipe you will be meeting, or just under your daily intake for fruit. If you feel like that is too much fruit, feel free to do 2 cups of fruit in each smoothie with 3 cups of leafy greens. Hope that helps. 🙂

    Just recently started juicing and using the same veggies for 4 days and drinking a large amount in the morning 64 oz about. Well day 5 I woke up to swollen face and thought it could be from make up I stopped juicing for 3 days and had a carrot and dates juice drink at night and I woke up with a half swollen face. Was wondering if any one else experienced any same symptoms.

      Hi Michellynn,

      Sounds like one of your ingredients aren’t sitting well with your body. We’re green smoothie lovin’ rawkstars all right, but we’re not doctors or nutritionists.

  76. Jennifer Hodges says:

    Hi there,
    I came looking on here, as I have been experiencing a weird sensitivity occasionally. Usually around my legs or feet. It’s like it is just under the skin…I’m not sure if I can say tingly..just a slightly painful sensitivity. It is annoying! I have been drinking a green smoothie most days for maybe 2 years now & don’t vary it much. Does that sound like alkaloid build up to you? Also, Romaine lettuce is known as Cos lettuce in Australia (just general info). Thanks 🙂

    • SGS Rawkstar says:

      Hi Jennifer,

      While we don’t know all of your medical history, it’s hard to determine if the sensitivity you’re experiencing is related to alkaloid buildup. But it might be worth taking a few days off of green smoothies to see if your symptoms subside. If they do, try rotating your leafy greens to prevent further build-up. If you continue to experience sensitivity we suggest reaching out to your physician.

      Cheers 🙂

  77. barry davies says:

    I have been using green smoothies for 4 years and am a fit 73 Y.O. I grow my own greens in my ezygrow patio gardens. I can plant 7 varieties and have a different one each day . This has worked well for me. The last group was 2 types of kale, boc choy, Wasabe lettice, chard and a variety of asian greens. I think picking live and clean is an advantage. I do believe we should vary the type of greens we use and also use a variety of herbs for health in them. I also grow 7 types in another Ezygrow.

No matter which greens I use, the smoothie is always full of foam and I have to leave it on the counter for several hours before the foam disappears so that I can add more smoothie to my container (which makes 3 cups and I drink all day at work). I love my smoothies but it’s so time-consuming to wait around for the foam to be reabsorbed. Someone said it wouldn’t foam if you use organic produce but my organic still foams. Any suggestions?

      Add some avocado! Gives a nice smooth texture and you won’t get any foam.

    • SGS Rawkstar says:

      Hi Kelly,

      Vitamix is a powerhouse blender, but all of that power can add extra air to your green smoothie causing them to foam. We suggest once you’ve blended your smoothie, set your blender to its lowest setting for a few seconds to allow your smoothie to settle. You can also try adding healthy fats like avocado or coconut oil to help prevent any foaming.

      Hope this helps!

    Had no problem on the first 5days… am i allergic to spinach??

    pls help

    • SGS Rawkstar says:

      Hi Lesley,

      This can be a common symptom if your body is not used to drinking or eating lots of fiber. Green smoothies are high in fiber which is great for digestion, but for newbies, the high fiber can shock your body. Make sure you drink lots of water to help flush things out. And if you’re new to green smoothies one serving a day is enough, which is 2 cups (16 ounces).

      Hope this helps!

    This website, first of all, got me extremely hooked on green smoothies. First thing I did after getting my summer job paycheck, was ordering my own blender for when I am at my dorm!

    However, rotating greens has been something I have wondering a lot. Right now, I mostly vary between one week of spinach, one week of kale. I found out rucola (=arugula) is also a good replacement for kale and others, but I just wondered: do I really need to worry about alkaloid buildup if I keep up this system, where I spread about 4 smoothies across the week?

    Another question I was wondering about, was about the freshness of for example the spinach. I leave it in the fridge and after a while, it of course starts to degrade a bit. Needs to worry about a few mushier or older leaves?

    Thanks again!!!

    • SGS Rawkstar says:

      Hi Didier,

      We’re so excited to have you blendin’ with us! Worried about alkaloid build-up? While build-up is rare, it’s something we should be aware of. We suggest rotating between two different leafy greens per week. And then another two different leafy greens the following week. So one week you might buy spinach and kale, and then on your next shopping trip, you might buy romaine lettuce and swiss chard.

      We suggest reaching for fresh greens, wilted greens don’t always yield the tastiest results! Finding your greens going bad too quickly? Freezing your leafy greens is a great option to prevent waste + it also great for your wallet! Learn all about freezing your leafy greens here…


      • Didier Goossens says:

        Gee, thank YOU for that tip! It is masterly thought!!!

        Be sure I will be using this one.

        Now, to get a bit technical: this week, I bought myself a mélange of greens, that includes baby spinach, some arugula, field salad (flat, super-green leaves), etc etc… What are your thoughts on that, as you are, in my opinion, the Sensei’s of Green Smoothies? 🙂

      • SGS Rawkstar says:

        Hi Didier,

        Yum! We love blendin’ different leafy greens together! Way to get a great leafy green nutrition boost!!! We still suggest adding different greens to your smoothies week to week to ensure you’re rotating your greens!

        Cheers 🙂

  86. SKDS says:

    I don’t just put one type of green in my smoothie. I put Kale, Spinach, cabbage, chard, celery, etc and whatever vegie’s I have. If I use a variety of vegies, will it stop the alkaloid buildup?

    • SGS Rawkstar says:

      Hi SKDS,

      You’re a leafy green rawkstar! And adding a wide array of leafy greens to your diet will help prevent alkaloid buildup, so keep doing what you’re doing!

      Cheers 🙂

    I was wondering if emulsification (NutriBullet) reduces the potency or the useable nutrients of greens. I have Googled the question and the matter seems to be unsettled. Some say there is very little reduction and some say the greens must be chewed and swallowed because blending or emulsification destroys the nutrient content. Some sites mention the lack of scientific studies to know which is opinion is true.What is your view?

    • SGS Rawkstar says:

      Hi Mark,

      Great question! I believe that Dr. Mercola says that people shouldn’t blend because all the nutrients are lost within 15 seconds, or something like that. We do believe that nutrients begin to “go away” and oxalate, but we don’t believe this happens in 15 seconds. Our stance is that green smoothies stay good for you for up to two days, as long as they are in a sealed container in the refrigerator.

  88. Karen Jackson says:

    I am so confused about what I’ve been reading with regard to kale – “It causes hypothyroidsim” and so on. It seems that the more I work to improve my diet, the more I seem to read horror stories about all the foods I have been using (qinuoa, raw kale, raw almonds, farro, cruciferous veggies, chia…). How am I to determine how much of what to ingest, how often to ingest it, and exactly how much is too much? Also, how do I measure raw kale? Do I chop it the way one would chop parsley, then measure one cup of the mutilated result? Do I put “x” number of leaves in a smoothie? Should I eat kale every other day, rather than daily? Is it always best to balance a smoothie with a small amount of fruit, a small amount of kale, a bit of celery, a few almonds, one teaspoon of chia seeds…??? I have been making a 32-ounce green smoothie every day for months. Help! How do we sort through all the stuff online about “I ate kale for three days and developed hypothyroidism”, versus “Kale is the super-food of the millenium”? And (sorry about the volume) – is it better to steam kale before putting it in a smoothie?

    Thanks so much!

    • SGS Rawkstar says:

      Hi Karen,

      Great questions! It’s important to rotate your greens. But to steer people away from consuming healthy amounts of fruits, vegetables, and create fear about eating healthy is sad to hear. There are some people whose bodies don’t respond well to high oxalates (which spinach + kale are known for having), but there are also people who can’t eat bananas, or mango, etc… It doesn’t mean everybody stops eating bananas or mango. It just means those few people who are allergic have to avoid it. Not everyone needs to avoid oxalates in their diet, but if you do, then you find alternatives. You can always check with your doctor to make sure, but it’s best to listen to your body.

      Hope this helps!

      Cheers 🙂

    Please reply to my email. I started with green smoothies and into the 2nd week became extremely constipated and even taking a laxative didn’t help. I had to see my dr and she asked me what greens I used. I told her spinach,chard & kale. At Costco they had all three in a large bag and bought this so I could freeze. She told me kale was my problem because it was hard to digest in the colon
    and to stop using. Also I saw after 2wks that my almond milk had 2% iron, and my flaxseed has iron
    and some frozen fruits had iron. I have never been able to take any iron in vitamins because it would make me constipated. Just recently at health food
    found coconut milk with no iron. Sweet and unsweetened. Use this now along with coconut water.
    Do you know of kale being hard on people. My dr’s
    MA told me she had a lot of gas with kale.
    Also forgot to mention I became so bloated and I
    am petite. My stomach had horrible pains.
    I do not want to give up on making smoothies and she my dr told me spinach is good plus avcoadco .
    In 8 months my HDL & LDL cholesterol levels dropped so low and she told me it was the avcoadco which did this.
    My question is chard also constipating. What are some greens I should avoid???
    Please help I don’t want to give up my smoothie
    Extremely grateful for your advice.

    • SGS Rawkstar says:

      Hi Helen,

      Thank you so much for reaching out! Everyone’s body is different, so everyone’s body + digestion reacts differently to new leafy greens. We’re so sorry to hear you were left bloated + constipated from blending with kale, next time you come across a kale recipe simply swap out kale for another leafy green you + your body enjoys more! Sensitive to iron, definitely skip almond milk for coconut milk, water, coconut water, or another low-iron liquid base option!

      Next time your stomach isn’t feeling its best, reach for ginger! Two compounds found in high concentration in ginger, gingerol and shoga, may help the entire digestive tract to relief any discomfort from gas, constipation, diarrhea, and bloating. Here are a few of our favorite ginger recipes, it also adds a great spice to any green smoothie recipe…




      Cheers to a lower HDL & LDL, RAWK ON!!

    Have you ever tried cauliflower greens? I’m out of everything in the house but have those in the garden.

    • SGS Rawkstar says:

      Hi Kirsten,

      You can absolutely blend cauliflower greens!!! You’ll find the cauliflower leaves a little bit firm and that they have a stronger taste than kale.

      Reach back out + let us know how you enjoyed blending with the cauliflower greens.

      Cheers 🙂
