I recently heard the claim that eating bananas on an empty stomach is bad for you, because of something related to magnesium or potassium levels in your body. A quick search found articles like the following:
Eating bananas on an empty stomach is not good for your health, because when the stomach is empty, there is nearly no food in the stomach that can be digested.
If in this moment one eats bananas, it will speed up the stomach's movement and the promotion of blood circulation, to increase the heart load. It is very easy to induce the myocardial infarction.
Banana is rich in magnesium. Eating banana with an empty stomach will suddenly increase the magnesium in the body and damage the balance between magnesium and calcium in the blood, which may has an inhibiting effect on the cardiovascular and is not conducive to human health.
Are there negative health effects associated with eating bananas on an empty stomach?
