Eating bananas on an empty stomach is not good for human health, because bananas are rich in sugar and fiber, which help digestion and laxative effects. There is no digestible food in the stomach in the morning on an empty stomach. Eating bananas at this time will speed up the movement of the stomach and intestines. Blood circulation increases the load on the heart and easily leads to myocardial infarction. Bananas contain a lot of magnesium. Eating more can greatly increase the magnesium content in the blood, which can inhibit the human cardiovascular system. It can cause obvious sensory numbness, muscle paralysis, and symptoms of lethargy.

It is generally safer to eat bananas after a meal or when you are not hungry.
