Watermelon Acai Smoothie Recipe


People reach out daily asking for cancer fighting foods. Many plants can natural heal the body + fight for health, check out this smoothie!

This Watermelon Acai Smoothie Recipe helps hydrate the body and boost the immune system.

We met rawkstars, Matt and Amanda, when they entered our Blendtec + Thrive Market giveaway and told us why they blend. It turns out Matt was diagnosed with brain cancer not too long ago. To help Matt along during his treatment, his wife Amanda started researching ways to help his body fight. She found numerous ingredients to help boost his immune system and she does this by making him delicious smoothies.

We asked Matt and Amanda to share a few of their favorite smoothies with us. This Watermelon Acai smoothie is one of Amanda’s very favorites.

As a base she uses watermelon, which has the highest cancer fighting properties of any fruit out there. It also has amazing hydrating properties and tastes great. To the watermelon she adds the antioxidant powerhouse, acai powder, as well as pomegranate powder which studies on prostate cancer have shown may slow the most aggressive forms by 67%.

If you’ve never heard of camu powder, you’re not alone. It a lesser-known superfood that comes from the camu berry. One half teaspoon of the pretty pink powder packs a whopping 600% of the recommended daily value of vitamin C. It works great in the acai smoothie recipe because it pairs well with watermelon.

Chia seeds are in there for protein and sustainable energy, as well as slowing the absorption of sugars, and antioxidant properties.

Citrus peel contains flavonoids which have been shown to penetrate brain cancer cells, facilitate their death by apoptosis, and lower their potential for invaded neighboring tissues. Citrus juice aids the liver in detoxification of carcinogens.

    Would ground chia seeds work in this recipe? If so would I use the same amount?

    Also, you mention pomegranate powder in the description, say pomegranate juice in the ingredient list, then say you can sub juice for the powder in the notes section. I assume in the ingredient list you mean to say 1/2 tablespoon of pomegranate powder instead of juice?

    • Simple Green Smoothies says:

      Hey there Julie! Thanks for catching that – yes, the recipe should be 1/2 Tbsp of pomegranate powder (sub with 1/4 cup pomegranate juice instead if needed). Ground chia seeds would work fine here, just use a little less than you would with the whole seed. Happy blending!

    This is a pretty adventurous smoothie! Do you have any advice on where to get the camu?
