In a 2005 study, researchers discovered a relationship between increased banana intake and a lower incidence of kidney cancer in women. Bananas have already been found to help men and women avoid colorectal cancer in a previous research. The presence of various antioxidant components, which have the effect of neutralizing the free radicals at the root of several illnesses, including malignancies, explains these anti-cancer benefits. There are two types of antioxidants found in bananas: vitamin C is one of the most effective antioxidants; and dopamine a neurotransmitter. Another prospective research of 61,000 Swiss women found a relationship between a high fruit consumption and a decreased risk of kidney cancer. Bananas had the greatest association of all the fruits tested, according to the researchers. Both women and men are reported to benefit from bananas when it comes to lowering their risk of colorectal cancer. Although bananas may not have the highest antioxidant content of any fruit, they do have a strong antioxidant capacity that may help prevent the beginning of some malignancies, cardiovascular disorders, and other chronic illnesses. Dopamine, a chemical from the catecholamine family, is claimed to be present in the popular Cavendish banana. Dopamine has antioxidant activity comparable to vitamin C, the most powerful water-soluble antioxidant. Because bananas contain both dopamine and vitamin C, their strong antioxidant capacity may be explained. Plantain is also a good source of phenolic chemicals, which are easily absorbed by the body and hence have a high antioxidant capacity.
