banana is one of the most popular fruits in the world. It is a familiar yellow food for both healthy people and old drivers.

and

but there is a question that people always have no answer: how many bananas are better to eat every day?

eating 6 bananas at a time may be fatal? There is a saying of

and

that there is a potential risk of eating six bananas at a time, and even that eating more than six bananas can be fatal. This topic once attracted the attention of BBC.

,

, ,

,

one of the world-famous disseminators of this saying is Carl Pilkington. He once argued in a video that eating more than six bananas at a time can kill people, because the potassium content in the body will exceed the safety limit, and seven bananas may cause danger.

and

however, what is quite meaningful is that Pilkington’s dialogue in this video is a famous British comedy director, whose masterpieces are “wonderful night in the Museum 2”, “the birth of lies”

this is a classic model of fabricating health rumors with chemical elements and special cases.

and

potassium is one of the most important nutrients for human survival. Katherine Collins, a nutritionist at St George’s Hospital in London, explained on the BBC programme that potassium is the equivalent of a charger to keep the cells working. Potassium element of

helps to keep heart rate stable, make pancreas release insulin normally, control blood glucose and more importantly blood pressure.

and

are too high or too low potassium, there is indeed a risk, will lead to irregular heartbeat, stomach pain, nausea, diarrhea and other symptoms. So, in the United States, potassium is also one of the chemicals used to carry out lethal injections, very high doses of which can cause cardiac arrest.

and

but for healthy people, it is almost impossible to eat bananas and lead to excessive potassium. It takes about 400 bananas a day to reach the potassium content of cardiac arrest.

and

any normal person who eats 400 bananas a day may have already burst his stomach and intestines before the explosion of potassium. Therefore, bananas are not dangerous at all. On the contrary, they were, are and will be healthy food.

how many bananas to eat every day?

and

according to international guidelines, adults should take 3500 mg (mg) of potassium every day, while an ordinary banana weighs about 125 g (g) and contains 450 mg of potassium.

and

means that if a healthy normal person only eats bananas to get potassium, it needs at least 7.5 roots to reach the standard. However, since other meals also contain potassium, not everyone needs to eat so many bananas every day. Moreover, some special people need to pay special attention to the weight of bananas. For example, patients with kidney disease, due to their reduced renal activity, can not excrete excess potassium through urination, so it may lead to high levels of potassium in the blood circulation, thus damaging the body and even fatal. In the

and

hospitals, there have been cases of heart attack in patients undergoing dialysis due to kidney disease due to eating too many potatoes (also rich in potassium). However, in addition to these special patients, healthy people eating bananas every day will not cause negative effects. Although there are some radioisotopes in bananas,

and

, if a passenger carries bananas through the U.S. Customs, it will trigger a sensor alarm and be suspected of smuggling nuclear materials. However, a banana contains only 0.1 microsievel of radiation. What level is this? For comparison, CT scans in hospitals expose people to 10 to 15 millisieverts of radiation, 100000 times more than bananas.

and

means that eating 100000 bananas will not cause radiation problems, which can be ignored.

according to the BBC, eating bananas in moderation is the best practice. That is, three roots a day. Can provide 1500 mg of potassium, research shows that eating bananas, 3 is a magic health number!

and

the amazing health benefits of eating three bananas a day.

and

bananas are a kind of low-cost, high-quality and multi-functional food. In addition to eating directly, they can also be used as desserts and baking seasonings. Foreign media reported that 96% of American families buy bananas at least once a month.

and

Reducing hypertension: the study found that three bananas a day had high potassium and nearly zero sodium, which could significantly neutralize the adverse effects of high sodium on blood pressure.

Prevention of anemia: banana is also rich in iron, iron can promote the hemoglobin in the blood, so as to fight anemia (lack of red blood cells or heme in the blood), so it can be eaten by people who are easily tired, pale or short of breath.

4. Improving digestion: many popular science experts forcefully refute the rumor, saying that scientific data show that dietary fiber (about 4G / root) in bananas is not enough to achieve the effect of defecation. But for many people, real life shows that bananas can regulate digestion, reduce the speed of food into the intestine, thereby improving constipation. Improve the digestive tract: banana will not stimulate the gastrointestinal tract, and can supplement the lost minerals for the digestive tract after diarrhea. Therefore, banana is one of the earliest solid food for infants. Vitamin supplement: banana is rich in vitamin C as oranges and strawberries, which can meet 15% of the daily requirement. Vitamin C is an important antioxidant to remove free radicals in the body, which can avoid the damage of human cells, ensure the health of blood vessels, and produce collagen which connects muscles, bones and other tissues.

7. Help the body to produce healthy cells: banana contains 20% of the vitamin B6 that adults need every day. This nutrient is an important element for the body to produce insulin, heme and non essential amino acids, and also helps the body to produce antibodies against inflammation. Improve sports performance: according to the research of human behavior Laboratory of Appalachia State University, cyclists eat half a banana in 15 minutes, which is equivalent to sports functional drinks. Because bananas can improve muscle function, many athletes eat one or two bites of bananas during the competition.

9. Inhibit appetite and lose weight: banana can achieve longer satiety, and its special flavor can reduce appetite after eating. Dr. Alan Hirsch of the smell and taste treatment and research foundation in Chicago, USA, found that Just smelling a banana can mislead the brain into believing that people have eaten it!

10. Bring pleasure: the medium-sized banana contains 27mg magnesium, which can help to improve mood and sleep; men and women need 420mg and 320mg magnesium daily, respectively, and are prone to anxiety, irritability, depression and other emotional diseases.
