1. Helps reduce weight in obese people

Among these, butyrate is utilized by the colonocytes and other SCFA.

Butyrate repressed the malignancy of intestinal epithelial cells (colon) and cause suppression of neoplastic cell activity.

3. Can help treat diarrhea 

Diarrhea is one of the well-known diseases of (GIT) gastrointestinal tract of children and adults. The green bananas are used to treat a diarrheal condition known as the green banana diet.

Maybe Flavonoids and saponins present in unripe banana have an anti-diarrheal activity to treat diarrheal conditions by suppressing the motility of the intestines.

4. Has hypoglycemic effects

Unripe banana has resistant starches (RS) in high quantity. This RS help in lowering the blood glucose level by increasing insulin sensitivity.

Resistant starches slowly digested and their glycemic index is low than other carbohydrates source.

This low glycemic property of unripe bananas results in the improved insulinemic state in patients by decreasing postprandial sugar levels.

5. Has anti-ulcer genic effects

Green bananas have anti-inflammatory and ulcer genic property due to the presence of phenolic compounds.

These compounds help in suppressing the production of histamines. And this in turn, causes the protection of gastric mucosa from the acidic environment of the stomach.

6. May improve cholesterol

Resistant starch (RS) present in green bananas (unripe) tends to have a reduced amounts of:

  • triglycerides
  • total fats
  • high and low-density lipoproteins, and
  • total cholesterol

RS can modify the low-density lipoproteins (LDL) to reduce the risk of CVD. Also, RS undigested portion lessens the blood cholesterol and plasma triglycerides level by binding with extra cholesterol and excrete into feces.

7. Enhances mineral absorption

Various examinations that RS of unripe banana could have a positive part in the absorption of minerals.

Absorption of calcium, phosphorus, iron, and zinc can be absorbed in intestines during digestion of resistant starches.

The outcomes come that consumption of a diet rich in resistant starches (dietary fiber) considerably increases calcium and iron absorption.
