First, avoid drinking a lot of cold drinks: if the temperature difference is too large, it will strongly stimulate the gastrointestinal tract, leading to sudden contracture.

Second, avoid eating bananas on an empty stomach: bananas contain a lot of magnesium in addition to potassium that helps sleep. If you eat on an empty stomach, the content of magnesium in your blood will suddenly increase. Magnesium is one of the sensitive elements that affect heart function.

Third, avoid eating pineapple on an empty stomach: pineapple contains strong enzymes, which will hurt the stomach on an empty stomach, and its nutrients must be better absorbed after eating.
