A lot of health and wellness experts like throw around words like antioxidant… but what does it mean and why do I need it? After experiencing several members in my family battle cancer more than once, I started researching antioxidant foods and how foods high in antioxidants can help not only keep me healthy, but fight for me too.

Best antioxidant rich foods

If you’re looking to up your intake of antioxidant rich foods, then take this list to the grocery store:

ArtichokesDark chocolatePomegranate
BeetsGoji berriesRaspberries
Black berriesKaleRed cabbage
BlueberriesOrange vegetablesRed grapes
CherriesPecansRed kidney beans

A good rule of thumb when browsing the produce section: if you buy dark leafy greens, red fruits, or berries then you are getting a cart full of antioxidants. Not to say that the other fruits + veggies are out of the running, they just provide different nutrients for the body.

While the foods on the above list are quite delicious, they are also super helpful to our bodies.

Why we need antioxidants

Antioxidants are molecules that specifically fight free radicals in the body. Why is this important? Well, if free radical counts get too high, then they can become super harmful. I’m talking cancer, heart disease, diabetes, and more.

While the body naturally has antioxidants, certain kinds of food also contain these special compounds, and eating these foods can give your defense system a big boost.

Free radicals also contribute to aging, so I’ll eat all the antioxidant foods I can to age a bit more gracefully + naturally.

Vitamins C and E are common as well as necessary antioxidants, and all the foods on the above list are full of these 2 essential vitamins.

    These are a staple in my freezer! I play around with ingredients depending on what’s in season, just trying to stick to the ‘red’ theme.

  2. Kim says:

    I love that this recipe is so easy and makes smoothie blending so fast! Delish!

  3. Jo says:

    I love the idea of these cubes. Sometimes I buy fresh fruit and something happens and I forget to eat it and it goes bad. This is a great idea to just make a batch at one point and have it frozen. Can you whiz up frozen berries as well? And what about fresh spinach?

  4. Sally says:

    Oh how I lurve lurve lurve this brilliant idea.
    My biggest obstacle is gathering all the ingredients daily. I’m exhausted just thinking about it. Chronic Fatigue is such a drag.
    So far I have made a medium sized jar of the organic powder supplements I like to add. Such as Kakadu plum, kale, beetroot, spirulina, maca, turmeric, matcha and hemp seeds. One rounded
    teaspoon adds it all.
    This one and your Vit C cubes really take it up a notch. BIG THANK YOU.

    • SGS Rawkstar Jess says:

      So glad they’re able to make your smoothie making easier, Sally!

  5. Stephan says:

    This is going to be one of my favorites………….for sure. As for blue….how about white cauliflower, blue berries, cucumber peeled, pineapple, coconut water, flax seeds (ground or whole). It comes out blue, not really a deep blue, but blue !
    P.S. I like the popsicle idea !

    • SGS Rawkstar Carissa says:

      Hey Stepha,

      Ooo that sounds like a great option! Thank you for sharing 🙂

  6. Christy says:

    The photography for this recipe is beautiful! I’m going to try these as healthy frozen popsicles.

    • SGS Rawkstar Carissa says:

      Thank you Christy! We really do have an amazing photographer. Cannot wait for you to try these out.

  7. Olivia says:

    These look AMAZING. So useful and practical. Gonna whip up a batch this weekend. Thanks Jen!

      Thanks Olivia! Cannot wait for you to give them a try 🙂

  8. Jen Hansard says:

    So glad you’re digging the smoothie cubes Dani! I have a few more coming up since they’ve been such a hit! As for swapping these for the cranberries in the Cranberry Kale Smoothie, that’s the perfect way to do it! you’ll be supercharging that smoothie with waaaay more antioxidants and the flavor will still be delicious. I would say any recipe that has cherries, cranberries, pomegranate, beets and strawberries will work really well to swap these cubes in. Thanks for rawkin’ out with us!

  9. Dani Mitchell says:

    I’m not a big fan of beets, but after reading all those health benefits I think I’m gonna give this one a go. I love all the other ingredients, especially pomegranate juice. I’ve been on a kick with that lately. Do you think these would taste better in a certain smoothie? Like I’m thinking I could take the Cranberry Kale Smoothie https://simplegreensmoothies.com/recipes/cranberry-smoothie and swap out the cranberries for a few smoothie cubes. Would that work?

    • SGS Rawkstar Carissa says:

      Hey Dani,

      Yes that would totally work! This would definitely be great to use in a smoothie that has berries in it. That way it will be a super easy swap!
