You suffer from intestinal symptoms, of bloating, gas or’irritable bowel (often called irritable colon) and you're wondering whether bananas are right for you?
In fact, the composition of different sugars varies according to the ripeness of the banana!
Brown/ripe banana
The riper the banana, the richer it becomes in simple sugar, fructan.
Fructan is a sugar belonging to the FODMAP, These are the sugars that are more fermentable in the intestine. Fructan is therefore easily fermented by intestinal bacteria, which can cause discomfort in those who are sensitive to it. For this reason, a maximum portion of 1/3 of a ripe banana is suggested for a single meal. low FODMAP diet.
Obviously, not everyone has an intestinal reaction to fructan. You have to try it out, if there's no reaction, don't limit yourself!
Green banana
Green bananas, on the other hand, are richer in resistant starch, an important prebiotic! This prebiotic ferments much more slowly, causing less gas and bloating for sensitive people. The green banana is low in FODMAP. Prebiotics, such as the resistant starch found in green bananas, are known to aid intestinal health as «food» for bacteria.
In fact, resistant starch is also found in legumes, oats, potatoes and rice when cooked and eaten cold! There's also green banana flour! A product to discover!
Yellow banana
A soft, uniform yellow banana is just the thing! It is richer in pectin, a sugar fermented at medium speed.
In conclusion?
Should I eat green or yellow bananas for the best prebiotic effect? No matter, the banana itself is a prebiotic and a fruit of choice!
Choose the color you prefer to taste, or else, the one you digest best!
