According to a 2007 study, eating bananas may help children with asthma from developing asthma. The main reason for this could be the antioxidant and potassium levels of bananas. More research is needed, however, to corroborate these conclusions.


Lectin, a protein found in bananas, has been shown in lab trials to help prevent leukemia cells from developing.

Lectin has antioxidant properties. Antioxidants aid in the elimination of free radical molecules in the body. Cell damage, which can lead to cancer, can occur when more radicals accumulate.

Researchers discovered in 2004 that youngsters who consumed bananas, orange juice, or both had a decreased risk of acquiring leukemia.

The authors of the study speculated that this could be related to the presence of antioxidant molecules in vitamin C.

Heart Health

Fiber, potassium, folate, and antioxidants like vitamin C are all found in bananas. All of them are beneficial to heart health.

A 2017 review found that people who follow a high-fiber diet have a lower risk of heart disease than those who eat a low-fiber diet. Those who ate a lot of fiber had low levels of low-density lipoprotein (LDL) or “bad” cholesterol.

Digestive Health

Bananas contain a good amount of water and fiber content, both of which promote digestion and promote digestive health. The average banana provides about 10% of a person’s daily needs.

Bananas are also part of the BRAT diet, which some doctors recommend to treat diarrhea. BRAT stands for banana, rice, applesauce, and toast.

Diarrhea can lead to loss of water and electrolytes, such as potassium. Bananas can replace these nutrients.

A high-fiber diet can cause constipation, gas, and stomach upset in people with inflammatory bowel disease (IBD), according to a 2012 study. However, bananas can improve symptoms, the authors conclude.

To ripen faster, people can try to keep them in a paper bag. Bananas in the fridge will grow slowly.
