Thanks to their high fiber content, green bananas help slow down sugar absorption and prevent sudden spikes in blood glucose after meals. The vitamin B6 in bananas also assists with hemoglobin production and improves oxygen delivery, helping cells use sugar more efficiently. For those watching their blood sugar, green bananas are a safer option than many quick-digesting starches.
3. Reduce risk of colon cancer – protect the gut microbiome
Resistant starch in green bananas acts like a prebiotic, feeding healthy gut bacteria and helping the large intestine maintain a balanced environment.
When these beneficial bacteria thrive:
- the intestinal lining becomes stronger
- inflammation in the gut decreases
- abnormal cell growth in the colon is reduced
For people who eat few vegetables, have a sedentary lifestyle, or consume a lot of processed food, green bananas may play an important role in lowering colon cancer risk.
