Bananas are among the most widely consumed fruits on the planet and, according to the U.S. Department of Agriculture, Americans' favorite fresh fruit. Like anything else, there's a health risk when consuming the fruit.
The curvy yellow fruits are high in "potassium and pectin, a form of fiber," Laura Flores, a San Diego-based nutritionist told Medicalnewstoday.com.
They can also be a good way to get magnesium and vitamins C and B6. "Bananas are high in antioxidants, which can provide protection from free radicals, which we come into contact with every day, from the sunlight to the lotion you put on your skin," Flores added.
Flores reported a wide variety of health benefits associated with the fruit. "Bananas are known to reduce swelling, protect against developing type-2 diabetes, aid in weight loss, strengthen the nervous system and help with production of white blood cells, all due to the high level of vitamin B6 that bananas contain," she told Live Science.
Bananas have seberal health benefits such as
1. Bananas help overcome depression due to high levels of tryptophan, which is converted into serotonin -- the happy-mood brain neurotransmitter.
2. Eat two bananas before a strenuous workout to pack an energy punch and sustain your blood sugar.
3. Protect against muscle cramps during workouts and nighttime leg cramps by eating a banana.
4. Counteract calcium loss during urination and build strong bones by supplementing with a banana.
5. Improve your mood and reduce PMS symptoms by eating a banana, which regulates blood sugar and produces stress-relieving relaxation.
6. Bananas reduce swelling, protect against type II diabetes, aid weight loss, strengthen the nervous system, and help with the production of white blood cells, all due to high levels of vitamin B-6.
7. Strengthen your blood and relieve anemia with the added iron from bananas.
8. High in potassium and low in salt, bananas are officially recognized by the FDA as being able to lower blood pressure and protect against heart attack and stroke.
Besides this eating more bananas can be harmful for health. Beta-blockers, a type of medication most commonly prescribed for heart disease, can cause potassium levels to increase in the blood. High potassium foods such as bananas should be consumed in moderation when taking beta-blockers.
Consuming too much potassium can be harmful for those whose kidneys are not fully functional. If your kidneys are unable to remove excess potassium from the blood, it could be fatal.
Eaten in moderation, there are no significant side effects associated with eating bananas. However, eating the fruits in excess may trigger headaches and sleepiness, Flores said. She said that such headaches are caused by "the amino acids in bananas that dilate blood vessels." Overripe bananas contain more of these amino acids than other bananas. "Bananas can also contribute to sleepiness when eaten in excess due to the high amount of tryptophan found in them," she said. Magnesium also relaxes the muscles - another sometimes-benefit, sometimes-risk.
Bananas are a sugary fruit, so eating too many and not maintaining proper dental hygiene practices can lead to tooth decay. They also do not contain enough fat or protein to be a healthy meal on their own, or an effective post-workout snack.
Eating bananas becomes significantly risky only if you eat too many. The USDA recommends that adults eat about two cups of fruit a day, or about two bananas. If you eat dozens of bananas every day, there may be a risk of excessively high vitamin and mineral levels.
The University of Maryland Medical Center reported that potassium overconsumption can lead to hyperkalemia, which is characterized by muscle weakness, temporary paralysis and an irregular heartbeat. It can have serious consequences, but you would have to eat about 43 bananas in a short time for any symptoms of hyperkalemia to occur.
According to the NIH, consuming more than 500 milligrams of vitamin B6 daily can possibly lead to nerve damage in the arms and legs. You would have to eat thousands of bananas to reach that level of vitamin B6.
