Bananas are a common fruit in our lives, loved by many. But there are folk sayings that "eating bananas on an empty stomach causes constipation" and "eating bananas on an empty heart increases the burden on the heart, easily leading to myocardial infarction." Are these sayings true or false? And besides peeling and eating them, are there other ways to eat bananas?
Eating bananas on an empty stomach causes constipation?
In fact, eating bananas on an empty stomach basically does not cause constipation, but eating unripe bananas might. Unripe bananas contain large amounts of starch, pectin, and tannic acid. The more tannic acid, the heavier the astringent taste of the pulp. Tannic acid is relatively insoluble and has a very strong astringent effect, which inhibits the secretion of digestive juices and their peristalsis, causing feces to become dry and hard, thus leading to constipation. The most typical case is that after the elderly and children eat bananas, not only does it not help with bowel movements, but they experience significant constipation instead.
Many people believe that bananas are rich in dietary fiber, and that dietary fiber can lubricate the intestines, so eating bananas can relieve constipation. However, according to food nutrition tables, the dietary fiber content in bananas is far less than that in oatmeal. Therefore, for most people, relieving constipation by eating bananas is just a psychological安慰.
Eating bananas on an empty stomach hurts the heart?
Folk wisdom holds that eating bananas on an empty stomach hurts the heart, which is closely related to the potassium and magnesium in bananas. For most people, eating bananas is not serious enough to affect heart health.
The normal blood potassium concentration is maintained at 3.5-5.5 mmol/L. If blood potassium is higher than this range, both healthy people and those with heart disease can potentially develop fatal arrhythmias, causing sudden death. In fact, eating a moderate amount of potassium daily helps maintain potassium-sodium balance, control blood pressure and vascular sclerosis, and prevent the occurrence of high sodium and low potassium. To a certain extent, it reduces the risk of diseases such as hypertension, coronary heart disease, and stroke, and plays a positive role in preventing myocardial infarction, so it is more suitable for patients with hypertension.
The magnesium content of one banana is about 14mg, varying depending on its size. According to data from the "Dietary Guidelines," the adequate intake of magnesium for adults is 350 mg/day. Excluding other magnesium-containing foods, you would need to eat 25 bananas to reach this standard, which obviously few people would do. Of course, our daily diet certainly includes other magnesium-containing foods. So this comes down to a matter of quantity.
Eating two or three bananas a day is perfectly fine.
