Banana laxative or constipator: what does science really say?

The banana, that yellow fruit adored by all, is often the subject of debate: does it constipate or help constipation? ? This question comes up again and again in my discussions with customers who are looking to optimize their diet to lose weight and feel good about themselves!

Today, I'm going to explain once and for all how this fruit really affects your transit and how to use it to your advantage.

Banana: laxative or constipating?

The answer may surprise you: It depends on the ripeness of the banana. ! A green or unripe banana contains a lot of resistant starch, a substance that slows down intestinal transit and can actually cause constipation.

Conversely, a ripe banana with brown spots contains soluble fiber and less resistant starch. This makes them easier to digest and helps regulate transit. The fiber it contains even promotes healthy intestinal function!

✅ A ripe banana contains around 3 grams of dietary fiber and acts as a natural regulator of intestinal transit.

How can bananas be used to combat constipation?

If you're looking to improve your bowel movements, choose ripe bananas with mottled skin. Their pectin content, a soluble fiber, helps to soften stools and facilitate their evacuation.

Here are my coaching tips on how to use them properly:

• Eat them for breakfast with a large glass of water to maximize the effect of the fiber.
• Combine them with probiotic-rich foods such as plain yoghurt.
• Avoid eating them on their own: add a few almonds or walnuts to boost fibre intake.
• Choose regular rather than occasional consumption

Constipation: ripe bananas or not?

To put it simply: ripe banana YES, green banana NO ! A study published in the British Journal of Nutrition has shown that the resistant starch present in green bananas can slow transit by up to 30%.

Do bananas constipate babies?

The question of banana and baby constipation is a concern for many young parents. Indeed, for toddlers, bananas can have a constipating effect, especially if they are not ripe enough.

For babies aged 6 months and over who are starting to diversify their diet, I recommend introducing bananas gradually and always when ripe. Mash it finely and offer it with other water-rich fruits such as pears or prunes.

If your baby shows signs of constipation after eating a banana, space them out and increase their hydration!
