Is it good for men to eat bananas on an empty stomach?

　　Eating bananas will not cause excessive magnesium intake and affect the heart

　　Bananas are rich in magnesium, but does eating bananas on an empty stomach really "suddenly increase the magnesium content in the blood, thereby affecting the heart"? The answer is no. Magnesium in food is mainly absorbed in the intestines, and the absorption rate is generally maintained at about 30%. Every 100 grams of banana contains 43 mg of magnesium. Based on a 100-gram banana, the magnesium intake is about 12.9 mg. According to the "Reference Intake of Dietary Nutrients for Chinese Residents" formulated by the Chinese Nutrition Society, the appropriate intake of magnesium for adults is 350 mg/d, and the maximum tolerated intake is 700 mg/d. In other words, unless you eat 55 bananas in one go, there will be no excessive intake of magnesium. Of course, the premise of considering excessive magnesium is that it is impossible to eat so many bananas at one time. In addition, green leafy vegetables contain the most magnesium in food, including whole grains, nuts and other foods that contain far more magnesium than bananas. However, no one has ever said that eating cabbage, soybeans, and buckwheat on an empty stomach will cause excessive magnesium intake and affect the heart. Therefore, eating bananas will lead to excessive magnesium intake and affect the heart. healthy The argument itself is untenable.

　　In the past, some people worried that bananas contain a lot of potassium. Will patients with heart disease eating bananas cause excessive potassium intake, which is harmful to the heart? Of course this question is also negative. Xiao Ji of Guoke.com once wrote: “The blood potassium concentration of normal people is maintained between 3.5 and 5.5mmol/L. If the blood potassium is higher than this range, fatal arrhythmias may occur in both normal people and heart disease patients, causing sudden death. The human body's daily demand for potassium is very large. A healthy non-pregnant adult needs about 2,000 mg of potassium every day. At the same time, the kidneys are the most powerful wastewater treatment plant in the human body and can filter 33,000 mg of potassium every day. Therefore, theoretically, even if a healthy person consumes more than 30 grams of potassium (about 13 tons of bananas) every day, his life will not be in danger. ”

　　Eating bananas on an empty stomach has a certain impact on gastric acid secretion

　　Some Weibo users claim that eating bananas on an empty stomach will significantly reduce gastric acid secretion. This statement is too ridiculous. The human stomach will continue to secrete gastric acid. Its basic excretion rate is about 10% of the maximum excretion rate, and it changes day and night. It reaches the peak a few hours after falling asleep and is the lowest before waking up in the morning. It is said that not eating will lead to a greatly reduced gastric acid secretion. After food enters the stomach, it will stimulate gastric acid secretion, thereby increasing the activity of pepsin and helping digestion. Some people experience heartburn, acid reflux, and vomiting after eating bananas on an empty stomach. This is because bananas are rich in carbohydrates. Under normal circumstances, carbohydrates do not have a very obvious impact on gastric acid secretion, but monosaccharides and disaccharides can particularly stimulate gastric acid secretion. It happens that most of the carbohydrates in fruits exist in the form of monosaccharides and disaccharides. Therefore, after eating bananas on an empty stomach, gastric acid secretion is greater than that of ordinary foods. Patients with peptic ulcers such as gastric ulcers and duodenal ulcers will have adverse reactions such as heartburn and acid reflux. People with excessive gastric acid will also experience discomfort. But in addition, normal healthy people will not feel any discomfort after eating bananas on an empty stomach, except for the rapid feeling of satiety.

　　It is appropriate to eat bananas to replenish energy during exercise

　　In sports events that consume a lot of energy, such as marathons and tennis matches, it is not difficult to find that players like to eat one or two bananas during half-time. This is because a lot of energy is consumed during exercise, and sweat also causes a large amount of potassium and sodium in the body to be lost. On the one hand, bananas are a high-potassium food that can replenish lost potassium in a timely manner, strengthen muscle strength and muscular endurance, and enable athletes to maintain continuous exercise; on the other hand, bananas are a high-energy food that contains monosaccharides and disaccharides that can be rapidly metabolized and generate a large amount of energy, supporting athletes with enough energy to continue the next exercise. Therefore, bananas are the first choice for most athletes to replenish energy during exercise.

　　Studies have pointed out that as global temperatures continue to rise, bananas may become a staple food for humans in the future. Regardless of whether the results of this study come true, Zhu Yi, associate professor at the School of Food Science and Nutritional Engineering at China Agricultural University, pointed out that bananas are a kind of food that grows from trees, and there is definitely no problem in eating them on an empty stomach. When eating, you should chew slowly and do not gobble it up. Eating two or three will not cause adverse physiological reactions, but if you have the foundation disease , just don’t eat if you feel uncomfortable after eating it. It can be seen that eating bananas on an empty stomach is not that scary, and there is no need to pay too much attention to whether to eat or not to eat, just listen to the voice from your body.
