Cancer
Laboratory investigations have suggested that lectin, a protein that occurs in bananas, may help prevent leukemia cells from growing.
Lectin acts as an antioxidant. Antioxidants help the body remove molecules known as free radicals. If too many free radicals build up, cell damage can occur, potentially leading to cancer.
In 2004, researchers noted that children who consumed bananas, orange juice, or both appeared to have a lower risk of developing leukemia.
The study authors suggested that this could be due to the vitamin C content, as this, too, has antioxidant properties.
Heart health
Bananas contain fiber, potassium, folate, and antioxidants, such as vitamin C. All of these support heart health.
A 2017 review found that people who follow a high fiber diet have a lower risk of cardiovascular disease than those on a low fiber diet. Those who consumed more fiber also had lower levels of low-density lipoprotein (LDL), or “bad” cholesterol.
Diabetes
The American Diabetes Association recommend eating bananas and other fruit as they contain fiber. They note that eating fiber can help lower blood sugar levels.
The author of a 2018 review concluded that eating a high fiber diet could reduce the risk of type 2 diabetes and may lower blood sugar in those who already have the disease.
