Apple Celery Smoothie, a Low Sugar Recipe

I’d like to share an apple celery smoothie recipe that’s surprisingly delicious. My favorite part of this smoothie is the fennel, a tasty herb that reminds me of black licorice. Yet I also love that it’s low in sugar and insanely energizing as well.

My love for Good & Plenty candy led me down a plant powered path to find a great smoothie recipe with a black licorice flavor. This recipe checks all the boxes: fun new ingredients, fresh flavor, low in sugar, and refreshing to the core.

Celery Smoothie Health Benefits

I know this smoothie may get a bad rap to start, with celery in the title, yet hear me out. The celery juice fad wasn’t just for fun. Celery is loaded with health benefits, including:

  • Antioxidants– Celery has at least 12 different types of antioxidants in just 1 stalk. 
  • Digestive Aid– this is a great veggie to eat daily as it has 5 grams of soluble fiber in 1 cup, which keeps things moving.
  • Helps reduce inflammation– The older I get, the more easily my body can succumb to inflammation. Celery helps fight this, making this celery smoothie a must on the menu when I’m training. 
  • Alkalizing effects: the minerals in this veggie can help neutralize acidic foods we eat. 
  • Full of vitamins and minerals: While celery is mostly water, it’s also got vitamins A, C, and K, along with potassium and folate.

Who knew this simple, whole food could be such a force for health and wellness?! I love knowing the benefits my body is getting from this celery smoothie recipe. Scientists have actually studied celery extract as an antibacterial and antimicrobial agent against treating MRSA (methicillin-resistant S. aureus) according to the National Library of Medicine.

Low Sugar Celery Smoothie Recipe

If you’ve ever gone on the hunt for a great low carb/low sugar green smoothie, look no further. A fruit or veggie is considered a low glycemic option (low in sugar) if 1 serving has a glycemic index score of less than 55. Check out the glycemic index of the ingredients in this celery smoothie recipe:

  • 1 cup spinach: less than 1
  • ¼ fennel bulb: 16
  • 1 celery stalk: 15
  • 1 green apple: 38
  • ¼ inch fresh ginger: 15
  • juice from 1 lemon: 20

My blood sugar’s doing a happy dance knowing this celery smoothie won’t raise it! This recipe can be a great afternoon pick-me-up, or even a refreshing evening treat to help stabilize the body’s blood sugar for the night.

    Hi! I’m not 100% sure how much a stalk of celery is. Is it just one “stick”.

    • SGS Rawkstar Jess says:

      Hey Oli! You are correct, it’s just one “stick.” The group of stalks (or sticks) is a bunch. You don’t need to put an entire bunch in! Happy blending! 🙂

  2. Angie Angelicchio says:

    Good morning,

    I would like if you can answer my questions.
    Can celery be frozen when in season? Does celery loose all or any nutritional benefits when frozen?
    Thank you very much.


    • SGS Rawkstar Jess says:

      Hey Angie! You can def freeze celery if you have a lot and don’t want it to go bad. In general, freezing helps retain the nutrient content of fruits and vegetables. However, some nutrients begin to break down when frozen produce is stored for more than a year. 🙂

    This smoothie needs to go into my regular rotation. Antioxidants, anti-inflammatory, *and* alkalizing?! You are speaking my language!!

  4. Susan Turner says:

    I like celery, so this smoothie sounds right up my alley. I never understood the “juicing celery” because it takes away the fiber— the best part! So blending the celery into the smoothie is def the way to go. Thank you for the weekly smoothie recipes to keep me inspired.
