BANANAS BENEFITS & HEALTH RISKS

3년 전

Bananas are one of the world's most appealing fruits.
Global banana exports reached about 18 million tons in 2015, according to the United Nations.
About half of them went to the United States and the European market.
In the United States, each person eats 11.4 lbs. of bananas per year, according to the U.S. Department of Agriculture, making it Americans' favorite fresh fruit.

A wide variety of health benefits are associated with the curvy yellow fruit.
Bananas are high in potassium and pectin, a form of fiber, said Laura Flores, a San Diego-based nutritionist.
They can also be a good way to get magnesium and vitamins C and B6.

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," Flores told Live Science.

"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.

HEART HEALTH ,,

Bananas are good for your heart.
They are packed with potassium, a mineral electrolyte that keeps electricity flowing throughout your body, which is required to keep your heart beating.
Bananas' high potassium and low sodium content may also help protect your cardiovascular system against high blood pressure, according to the FDA.

A 2017 animal study conducted by researchers at the University of Alabama found that the potassium in bananas is also linked to arterial effectiveness; the more potassium you have, the less likely your arteries are to harden.
In the study, mice with lower-potassium diet had harder arteries than mice consuming a normal amount of potassium.
Arterial stiffness in humans is linked to heart disease.

              <  DEPRASSION AND MOOD  >

Bananas can be helpful in overcoming depression "due to high levels of tryptophan, which the body converts to serotonin, the mood-elevating brain neurotransmitter," Flores said.
Plus, vitamin B6 can help you sleep well, and magnesium helps to relax muscles.
Additionally, the tryptophan in bananas is well known for its sleep-inducing properties.

         <  DIGESTION AND WEIGHT LOSS  >

Bananas are high in fiber, which can help keep you regular.
One banana can provide nearly 10 percent of your daily fiber requirement.
Vitamin B6 can also help protect against type 2 diabetes and aid in weight loss, according to Flores.
In general, bananas are a great weight loss food because they taste sweet and are filling, which helps curb cravings.

Bananas are particularly high in resistant starch, a form of dietary fiber in which researchers have recently become interested.
A 2017 review published in Nutrition Bulletin found that the resistant starch in bananas may support gut health and control blood sugar.
Resistant starch increases the production of short chain fatty acids in the gut, which are necessary to gut health.

                     <  BONES  >

Bananas may not be overflowing with calcium, but they are still helpful in keeping bones strong. According to a 2009 article in the Journal of Physiology and Biochemistry, bananas contain an abundance of fructooligosaccharides.
These are nondigestive carbohydrates that encourage digestive-friendly priobotics and enhance the body's ability to absorb calcium.

                    <  CANCER  >

Some evidence suggests that moderate consumption of bananas may be protective against kidney cancer. A 2005 Swedish study found that women who ate more than 75 servings of fruits and vegetables cut their risk of kidney cancer by 40 percent, and that bananas were especially effective.
Women eating four to six bananas a week halved their risk of developing kidney cancer.

Bananas may be helpful in preventing kidney cancer because of their high levels of antioxidant phenolic compounds.

                   <  PREGNANCY  >

While not exactly a health benefit, a study published by The Royal Society found that the potassium in bananas is correlated with women giving birth to baby boys.
The study looked at 740 women and saw that those who consumed high levels of potassium prior to conception were more likely to have a boy that those who did not.

Bananas may also help prevent gestational diabetes.
Lack of sleep during pregnancy can contribute to gestational diabetes, according to a meta-analysis published in Sleep Medicine Reviews.
But the magnesium and tryptophan in bananas can help ensure a good night's rest.

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.
