Gut Healing Tropical Smoothie


This smoothie is gluten-free, dairy-free, low in FODMAPs, and contains gut-healing ingredients like collagen peptides. With strawberries, bananas, pineapple juice and coconut oil, it is delicious and nutritious. for every body!

Further Food Nutritionist Commentary:

Pineapples contain bromelain, an anti-inflammatory compound*. Coconut oil is easy to digest and its fatty acid structure causes it to be utilized for energy and not stored in our fat cells. But the heavy hitters in this smoothie are the L-glutamine and collagen, both of which can help repair leaky gut.

The lining of the GI tract has a very selective system of letting in the good (vitamins and fully digested nutrients) and keeping out the bad (whole proteins, bacteria, yeast). There are tight junctions that do this. When the digestive tract is over-taxed (as it is in many of us), any number of stressors, such as NSAIDs, bad bacteria, IBS, digestive disorders, gluten, or alcohol, can cause the tight junctions to not be so tight. Collagen and L-glutamine (an amino acid) are said to help repair the lining.

*If sugar content is an issue, reduce the amount of juice and sub in water.

    L-glutamine is just an amino acid, that we eat everyday so it shouldn’t cause a problem. Collagen is protein powder, so i would use with caution if other protein powder was a problem. Also, No smoothie is going to give anyone everything they need. 🙂 Feel free to check out my website for info on IBS and gut healing 😉

    I had a stroke after drinking a protein powder drink and found out I have MTHFR deficiency. I’m not good at figuring out what is safe so I avoid anything that contains vitamins. We all suffer from IBS and gluten intolerance so we really need a smoothie that gives us all the nutrients we need. Would you have any idea if the 1 teaspoon of collagen and 1 teaspoon of L-glutamine powder would be safe or a food substitute we could add instead

    I can’t have bananas they affect my sinuses. Is it ok to leave it out or can something be put in place of the banana
