Constipation can be the result of one or more of the following: not enough dietary fibre, low fluid intake, or not moving their bodies enough. On the other hand, too much fibre paired with not drinking enough fluid can also lead to constipation! As you can see the answer is not simple. What we do know is that bananas are a good source of both soluble and insoluble fibre. Soluble fibre attracts water and forms a gel to help create bulk to help regulate digestion. Insoluble fibre passes through the digestive system unchanged, helping to “push things along” and promote healthy bowel movements. Bananas generally help promote regular bowel movements in babies because its is a good source of both of these fibres. However, as mentioned above, too much fibre (or too much banana) can plug up the digestive system when not in balance with enough movement or fluid intake.
