There are different opinions on whether bananas are suitable for people with type 2 diabetes. It is true that they contain a lot of starch and sugars, so it might seem that they may be the cause of a sharp rise in blood sugar levels. On the other hand, they have a low glycemic index, so moderate consumption of bananas should not lead to a higher increase in blood sugar levels compared to other carbohydrate-rich foods.

Thus, according to the above, people with diabetes should avoid eating larger amounts of overripe bananas. It is best to always monitor your blood sugar levels when consuming large amounts of sugar- and carbohydrate-rich foods.

Likewise, some studies state that bananas are a risky food because they cause constipation and others claim that they have the opposite effect. When consumed in normal amounts, they should not have any adverse effect.

Some studies indicate that people who are allergic to latex are also sensitive to bananas and some other plant fruits. Bananas, as well as for example, papaya, figs, pineapple or avocado, contain peptides which may so-called latex-sensitive populations bother.
