If these patients eat bananas, it is not good for their health. There are also patients with swollen feet during pregnancy, and it is best not to eat bananas.

2. People on an empty stomach

Bananas can promote gastrointestinal peristalsis. If you eat on an empty stomach, your stomach will work ahead of schedule. Eating bananas on an empty stomach for a long time is bad for your health. Because there is almost no digestible food in the stomach on an empty stomach, eating bananas on an empty stomach will speed up the movement of the stomach, promote blood circulation, enhance the load on the heart, and easily lead to myocardial infarction.

3. Arthritis patients and diabetic patients

Bananas with high sugar content will slow down blood circulation and accumulate metabolites. Arthritis and diabetes patients should not eat bananas, otherwise it will aggravate the condition.

Patients with nephritis can't eat bananas because bananas contain a lot of potassium and magnesium, and the filtration function of patients with nephritis is relatively poor. Bananas can make the proportion of calcium, potassium and magnesium in blood unbalanced, thus promoting the aggravation of kidney diseases, so patients with kidney diseases had better not eat bananas.
