The glycemic index of bananas also becomes high when they are cooked - baked, fried, or grilled. A low-GI diet can protect you from diabetes, heart disease, atherosclerosis, and kidney disease.

People suffering from this disease should choose lean meats and fatty marine fish (e.g., salmon, herring, mackerel), which are best steamed or stewed.

Vegetable oils such as canola and olive oil are the most beneficial for health. An important habit that people with type 2 diabetes should develop is drinking still water with low sodium content and herbal and fruit teas without sweetening.

Ready-made nectars and drinks should be replaced with homemade vegetable and fruit juices, which are much healthier and devoid of excess sugar, artificial colouring, or preservatives. It is worth mentioning that patients with normal weight can consume no more than 15 g of simple sugars per day.

Contrary to popular myths, bananas' glycemic index is not high. The most important characteristic of this fruit, which will allow a diabetic to choose a better option for himself, is its ripeness. It is important to remember to choose the less ripe pieces.

The differentiating feature is the glycemic index value, which is 51 in a ripe banana and drops to 30 in a green banana. This drop is due to the resistant starch found in it. It causes the energy from the banana to take longer to be released, so there is no rapid rise in glycemia after consumption. An additional benefit is its beneficial effect on the gut microbiome.
