What Is Banana Good For?

Besides its taste, bananas are full of other nutrients such as vitamins and minerals like vitamin B6, vitamin C, potassium, copper, manganese, and magnesium, as well as antioxidants. 

Bananas have high contents of dopamine and catechins which are strong antioxidants. Antioxidants are chemical compounds that react with free radicals in the body and prevent oxidative stress. (*)

While you might think that dopamine will alter your mood, since it is often labeled as a “feel good” hormone, that is just not the case with the dopamine from bananas. The kind of dopamine that comes from bananas does not cross the blood-brain barrier, therefore it only acts as an antioxidant. 

Bananas are also a great way to add some potassium and magnesium in your diet, as both are very important for cardiovascular health, especially for the regulation of blood pressure. Therefore magnesium and potassium can help lower the risk of cardiovascular disease. (*), (*)

Eating bananas has also been linked to a 33%  lowered risk of kidney disease, which was concluded in a 13-year study where people ate bananas 2-3 times per week. (*)

Unripe bananas contain resistant starch which can slow down digestion and help you feel full, therefore helping with weight loss. Resistant starch has also been linked to lowering insulin resistance and improving insulin sensitivity in obese men over a short amount of time. (*), (*)
