occasionally, I see on the Internet that you can’t eat bananas on an empty stomach. Is it true that bananas can’t be eaten on an empty stomach? Is it good or bad to eat bananas on an empty stomach? In fact, bananas can be eaten on an empty stomach, but if patients with diseases feel uncomfortable, they can not eat them. Let’s learn about it.
Bananas are rich in magnesium, but eating bananas on an empty stomach really can & lt; It makes the magnesium content in the blood rise suddenly, and then affects the heart; Is that right? 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. According to 100 grams of a banana, the intake of magnesium 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 tolerable intake is 700 mg / d. that is to say, unless 55 bananas are eaten at one time, there will not be excessive magnesium intake. However, the premise of considering excessive magnesium is that so many bananas cannot be eaten at one time. In addition, green leafy vegetables contain the most magnesium in food, 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, it is untenable to say that eating bananas will lead to excessive magnesium intake and affect heart health.
in the past, some people worried that bananas contain a lot of potassium. Will eating bananas lead to excessive potassium intake for heart patients, which is harmful to the heart? Of course, this question is also negative. Xiao Jizeng of guoke.com pointed out in an article: & lt; Normal people’s blood potassium concentration is maintained in the range of 3.5 ~ 5.5mmol/l. If blood potassium is higher than this range, both normal people and heart patients may have fatal arrhythmia, causing sudden death. The human body needs a large amount 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, which can filter 33000 mg of potassium every day. Therefore, in theory, even if healthy people take 30 grams of potassium (about 13 tons of bananas) every day, they will not be life-threatening& rdquo;
Eating bananas on an empty stomach has a certain effect on gastric acid secretion. It is ridiculous to say that eating bananas on an empty stomach can lead to a significant reduction in gastric acid secretion, according to a microblog. The basic excretion rate of gastric acid is about 10% of the maximum excretion rate, and it changes day and night. It reaches the peak hours after falling asleep and the lowest before waking up in the morning. Food into the stomach will stimulate gastric acid secretion, and then increase the activity of pepsin, 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, carbohydrates have no significant effect on gastric acid secretion, but monosaccharides and disaccharides can 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, 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 heartburn and acid regurgitation adverse reactions, and people with too much gastric acid will also have discomfort. But in addition, normal healthy people after eating bananas on an empty stomach, in addition to the rapid sense of satiety, there will be no discomfort.
It’s suitable to eat bananas to supplement energy during exercise. It’s not hard to find that athletes like to eat one or two bananas at half-time in marathons, tennis and other sports events that consume physical strength sharply, This is because exercise consumes a lot of energy, and sweat also makes the body lose a lot of potassium and sodium. On the one hand, banana is a high potassium food, which can timely supplement the loss of potassium, strengthen muscle strength and endurance, so that athletes can maintain a sustained state of movement; On the other hand, banana is a kind of high energy food, which contains monosaccharide and disaccharide, which can be metabolized rapidly and produce a lot of energy to support athletes to have enough energy to continue the next movement. Therefore, most athletes supplement energy in the process of sports, the first choice is banana.
