Top 5 Health Benefits of Bananas + Nutrition Info and Fun Facts
Many people have heard that bananas are a good source of potassium, but their health benefits go way beyond that.
Bananas are an excellent source of vitamin B6, and a good source of vitamin C and fiber. They also contain a lot of antioxidants, which may protect against health problems including cancer, heart disease, and Alzheimer’s (1).
The convenient, single-serve packaging that bananas come in (the peel!) makes this fruit a hard one to beat for convenience. So, pack one in your lunchbox, chop it into a fruit salad, or slice it into your cereal- and add some great nutrition to your day!
Bananas Health Benefits
1. Bananas may help prevent kidney cancerBananas are very high in antioxidants, which may be why they seem to reduce kidney cancer risk. In a study of 61,000 women, those who ate at least 4-6 bananas each week had about half the risk of kidney cancer as those who did not eat bananas (2).
2. Bananas can help athletic performanceBananas replenish energy and electrolytes during endurance exercise at least as well as sports drinks. In a study of long-distance cyclists, refueling with a banana and water resulted in performance times equal to refueling with a sports drink. Other measures of performance were also similar for both groups (3).
3. Bananas may help with childhood asthmaIn children with asthma, eating bananas may lessen symptoms. A study of over 2600 children ages 5-10 years found that those who ate at least one banana each day were 66% less likely to experience wheezing than those who did not eat bananas. Other potential causes of asthma symptoms were similar between the two groups (4).
4. The potassium in bananas protects heart healthFoods that are high in potassium and low in sodium, like bananas, may reduce the risk of high blood pressure and stroke. In one study, people who ate bananas frequently had significantly lower blood pressure than those who ate them less often (5). A review of many studies on the topic found that people who eat more potassium-rich foods have a 24% lower risk of stroke (6).
5. Bananas are an excellent source of vitamin B6A single medium banana provides 22% DV for vitamin B6 which is basically a quarter of your daily goal. Vitamin B6 is important for brain development and function, energy production (turning food into usable energy), healthy immune function, and red blood cell production (7).
