The banana trick to empty your bowels is where you eat a fully ripe banana first thing in the morning on an empty stomach to empty your bowels immediately.
The banana trick to empty your bowels is a popular social media hack.
The banana trick does help some and is healthy for you although a banana alone is not a medical cure and won't instantly empty your bowels but eating a banana first thing in the morning is still healthy and can help keep your bowels moving.
The banana must be fully ripe, because as bananas ripen, when they turn yellow with brown spots, the heavy starches in the bananas convert into simple sugars and soluble fiber.
Then the soluble fiber in the bananas absorbs water in your intestines, which then form a gel like substance that also softens your poop and makes your poop easier to pass.
Bananas are also rich in magnesium and potassium.
The potassium in the bananas stimulates the smooth muscle contractions also known as peristalsis in your colon to push the waste out.
And the magnesium in the bananas draw water into your bowel for a mild osmotic laxative effect.
Although if you do this trick with a green or underripe banana it will have the opposite effect and result in constipation instead.
This is because unripe bananas are packed with resistant starch and tannins, which also slow down your digestive tract and are also heavily used in treating of diarrhea, like in the BRAT diet.
