Sihaiwang: banana is the most common fruit in our life. Banana not only tastes good but also has rich nutritional value. It's a kind of fruit suitable for all ages. But someone on the Internet said that you can't eat banana on an empty stomach. It's bad for your stomach and body. Is that true? What are the taboos to eat bananas? Let's have a look!
Can bananas be eaten on an empty stomach
Eating banana will not lead to excessive magnesium intake, which will affect the heart banana's rich magnesium content. However, eating banana on an empty stomach can really increase the magnesium content in the blood, thus affecting the heart? The answer is No. Magnesium in food is mainly absorbed in the intestine, and the absorption rate is generally kept at about 30%. There is 43mg magnesium in every 100g banana. According to 100g of a banana, the intake of magnesium is about 12.9mg. According to the "reference intake of dietary nutrients for Chinese residents" formulated by the Chinese society of nutrition, the suitable intake of magnesium for adults is set as 350mg / D, while the maximum tolerable intake is 700mg / D, that is to say, unless 55 bananas are eaten at a time, there will be no excessive intake of magnesium. However, the premise of considering excessive magnesium is that so many bananas cannot be eaten at one time. In addition, the most magnesium content in food is green leaf vegetables, including coarse grains, nuts and other foods, which also contain much more magnesium than bananas. However, no one has ever said that eating cabbage, soybeans and buckwheat on an empty stomach will lead to excessive magnesium intake, which will affect the heart. Therefore, eating bananas will lead to excessive magnesium intake, which will affect the heart health.
There have been concerns in the past that bananas contain a lot of potassium. Will eating bananas lead to excessive potassium intake which is harmful to the heart? Of course, this question is also negative. Xiao Jizeng, the author of guoke.com, points out that 'the concentration of blood potassium in normal people is maintained between 3.5 and 5.5mmol/l. If the concentration of blood potassium is higher than this range, fatal arrhythmia may occur in both normal people and heart patients, resulting in sudden death. The human body needs a lot of potassium every day. A healthy non pregnant adult needs about 2000 mg of potassium every day. At the same time, the kidney is the most powerful wastewater treatment plant in the human body. It can filter 33000 mg of potassium every day. Therefore, in theory, even if the healthy person ingests 30 grams of potassium every day (about 13 tons of bananas), there is no life risk. '
Eating bananas on an empty stomach has a certain impact on gastric acid secretion. According to Weibo, eating bananas on an empty stomach will greatly reduce gastric acid secretion, which is ridiculous. The human stomach will continue to secrete gastric acid, and its basic excretion rate is about 10% of the maximum excretion rate, which changes day and night. It reaches the peak several hours after falling asleep, and it is the lowest before waking up in the morning. If you don't eat, the gastric acid secretion will be greatly reduced. After the food enters the stomach, it will stimulate the secretion of gastric acid, and then increase the activity of pepsin to help digestion. Some people will feel heartburn, acid regurgitation and vomiting after eating bananas on an empty stomach, because bananas are rich in carbohydrates. In general, carbohydrate has no significant effect on gastric acid secretion, but monosaccharide and disaccharide can especially stimulate gastric acid secretion It happens that most of the carbohydrates in fruits are in the form of monosaccharide and disaccharide. Therefore, after eating bananas on an empty stomach, the secretion of gastric acid is more than that of ordinary food. Patients with peptic ulcer such as gastric ulcer and duodenal ulcer will have adverse reactions of heartburn and acid regurgitation, and people with excessive gastric acid will also have discomfort. But in addition, after eating bananas on an empty stomach, normal healthy people will not feel any discomfort except for the sense of satiety.
It's not hard to find that banana is suitable for energy supplement in sports, such as marathon, tennis and other sports events that consume physical strength rapidly. Players like to eat one or two bananas during the intermission, because a lot of energy is consumed in the process of sports, and sweat will also cause a large loss of potassium and sodium in the body. On the one hand, banana is a high potassium food, which can supplement the lost potassium in time, strengthen the muscle strength and muscle endurance, so that the athletes can maintain the continuous exercise state; on the other hand, banana is a high energy food, which contains monosaccharide and disaccharide which can quickly metabolize, produce a lot of energy, and support the athletes to have enough energy to continue the next exercise. Therefore, banana is the first choice for most athletes to replenish energy during sports.

Four taboos to eat bananas:
1. Immature bananas are prone to constipation
Bananas that are not ripe will have astringent taste, mainly because of the large amount of tannic acid contained in bananas. When banana ripens, although it can't taste astringency, tannin still exists. Tannic acid has a very strong astringent effect. It can form excrement into dry and hard excrement, thus causing constipation. The most typical is the elderly, children eat bananas, not only can not help defecate, but also can have obvious constipation.
2. Excessive consumption of banana may cause imbalance in the proportion of trace elements
Some people eat bananas a lot at a time. I don't know. It's very bad for your health. Banana contains more magnesium, potassium and other elements. Although these mineral elements are necessary for human health, if they are ingested too much in a short time, it will cause a sharp increase in the content of magnesium and potassium in the blood, resulting in the imbalance of the proportion of potassium, sodium, calcium, magnesium and other elements in the body, which is harmful to health. In addition, eating more bananas will cause gastrointestinal dysfunction and excessive mood fluctuation due to the greatly reduced gastric acid secretion. Therefore, banana should not be overeated.
3. Bananas should not be refrigerated in the refrigerator
The storage temperature of bananas is generally 11-13 ℃, while that of fruits and vegetables in refrigerators is generally about 4 ℃, up to 8 ℃. If banana is placed in this environment, it is easy to be frozen, and it will turn black in one day, and the quality will become soft and rotten, and the taste will become bad, even there will be patches or rotten.
