Benefits of this low fodmap protein shake recipe
This IBS protein shake is full of nutritional powerhouse foods, such as hemp seed protein, which is my favorite low fodmap protein source. I prefer whole food protein sources, especially hemp seeds and collagen powder..
According to Cronometer, the low fodmap protein smoothie contains all the B vitamins except B12 but is exceptionally high in B1, B3, B6, and folate. It is also a great source of vitamin D, E, calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc.
Folate is an important nutrient involved in methylation, a process that helps the body produce S adenosylmethionine (SAMe). SAMe serves as a methyl donor for the PEMT pathway, which helps the body produce phosphatidylcholine. Phosphatidylcholine is required for healthy bile production and bile flow.
Since bile has antimicrobial properties that help regulate bacteria in the small intestine, supporting methylation and phosphatidylcholine production may play an important role in maintaining digestive health and reducing factors that can contribute to SIBO.

Hemp seeds are an excellent source of plant protein and essential fatty acids, including anti-inflammatory omega-three fats.
I added 10 grams of collagen powder to boost the protein content in this low fodmap protein smoothie. If you prefer to make a vegan smoothie you can omit the collagen powder or use an alternative low fodmap protein powder.
Walnuts are another rich source of omega-three fats for brain health. The addition of walnuts provides an ultra-creamy texture and healthy fats to keep you satisfied and energized with long-lasting energy.
Cacao powder is an excellent source of magnesium which is a prevalent nutritional deficiency that is beneficial for blood sugar balance. This smoothie contains 313 mg of magnesium, almost the recommended daily intake. Be sure to make this low-fodmap chocolate smoothie full of magnesium if you find yourself craving chocolate while on the low-fodmap diet!
Bananas are fodmap friendly when firm and not overripe, although 1/3 of a ripe banana is low fodmap according to research at Monash University. An unripe banana or firm banana is low in the fodmap oligo-fructans.
As bananas ripen, the fodmap content of oligo-fructans increases, making ripe bananas high fodmap, but a medium sized firm banana is considered a low-fodmap serving. Cacao powder and bananas are like two peas in a pod. They combine beautifully together to make an ultra-creamy low fodmap IBS protein shake.
The banana naturally sweetens this low fodmap chocolate smoothie perfectly. Half a banana is allowed on phase 2 of the SIBO diet, making this SIBO friendly smoothie recipe suitable for phase 2 of the Bi-phasic diet.
Tips and substitutions for the low fodmap protein smoothie
I added ice cubes to make this low fodmap smoothie chilled as I did not have frozen bananas on hand. Using a frozen banana is optional to make a cold smoothie.
Almond milk is a delicious low fodmap milk that tastes amazing in creamy smoothies and shakes, but you can substitute it with another non-dairy milk such as rice milk which is low fodmap in 3/4 cup serving size.
Unsweetened soy milk is another low fodmap milk that is great to make this low fodmap protein shake recipe as 1 cup of soy milk contains 9 grams of protein!
Additional low fodmap protein sources that you could add include vitessence pea protein isolate, which Monash University has tested to be low fodmap in a serving size of 75 grams. Sprouted brown rice protein powder is also low fodmap in a serving size of 2 tablespoons.
You could also add small amounts of peanut butter, which complements banana and cocoa powder. The original recipe tastes amazing, but never be afraid to tailor this IBS protein shake to suit your needs and taste buds :)
Enjoy this perfect breakfast smoothie anytime you crave chocolate, especially on a hot summer day!
