Green bananas are rich in fiber. The nutrient helps in bulking up the stool and improving bowel movements. This improves the digestive process and prevents constipation. It also helps in reducing the risk of colon cancer (4).

Resistant starch is made of complex carbohydrates and is broken in the gut. This fiber acts as a prebiotic for the gut microbiome. The bacteria that live in the gut use this fiber and convert it into important nutrients that the body can use. Among such byproducts are the short-chain fatty acids, like butyrate (5).

Green bananas may be good for both constipation and diarrhea. Research studies have found that they could be therapeutic for children with recurring diarrhea (6). A rat study suggests that green bananas may be potentially active against mucosal lesions in the stomach (7).

These compounds are known to protect against cancer, heart disease, cataractsⁱ  A condition in which the eyes’ natural lens turns cloudy and causes blurriness, especially in aged people. , and age-related vision loss.

Jenna Volpe, RDN, LD, CLT, says, “Green bananas contain special antioxidants which may be beneficial for people with degenerative diseases such as Parkinson’sⁱ  A degenerative disorder that affects the central nervous system. Its symptoms include loss of balance, stiffness, and slow movement. , Alzheimer’s, cancer and cardiovascular disease (1).”
