For certain categories of people, eating bananas may be particularly undesirable.

1. Diabetes. Bananas sold in supermarkets are often artificially ripened, which leads to high blood sugar levels. If you have diabetes, it is recommended to eat unripe fruit. 2. Obesity. Artificially ripened bananas also contribute to metabolic disorders and the formation of fat cells, so it is not recommended for use in case of obesity. 3. Arterial hypertension. Bananas cause the blood to clot and cause fluid to be removed from the body, which can be dangerous for people with high blood pressure.

4. Varicose veins, heart disease. Due to the ability of bananas to thicken the blood, it is not recommended for diseases such as thrombophlebitis, varicose veins, coronary artery disease or those who have had a stroke or heart attack. 5. Digestive problems. Bananas can worsen certain digestive conditions, such as irritable bowel syndrome. In such cases, the use of bananas should be agreed with the doctor and used with caution. 6. For people with kidney problems, excessive consumption of bananas can cause serious damage. It's all about the huge amount of potassium that these fruits contain. Remember that one of the functions of the kidneys is to control the level of potassium in the blood. If the kidneys are weak, any food rich in potassium, especially bananas, should be excluded from the diet.
