Sweet watermelon pulp contains simple sugars and is a high glycemic index (GI) product. Products with increased GI (over 70) should be avoided by diabetics and people who want to lose weight, but watermelon is considered a pleasant exception to the rule. We will find out what GI and composition of a watermelon, how it is useful and how to use it, what are contraindications.
What is the glycemic index of watermelon?
Sugars, which are in the pulp of watermelon, are quickly broken down into glucose in the body, therefore the glycemic index of this berry is quite high - 65–70 units. A well-ripened and accumulated many sugars sweet fruit has it even higher - 75.
Did you know? Not only the product, but also the method of its preparation can influence the level of GI. So, in boiled carrots it is very high (85), and in raw carrots it is much lower (35). Fried potatoes have a GI of 111, and boiled in their uniforms - 65, mashed potatoes - 90.
When eating foods with high glycemic levels in a person’s blood glucose level rises quickly, and the pancreas begins to actively produce insulin. This leads to the accumulation of body fat.
The feeling of fullness quickly disappears and a person very soon wants to eat again. Most high-GI foods are baked goods and sweets, and low-GI foods include cereals and legumes, many vegetables and fruits, dark chocolate, and dairy products.
However, the attitude of nutritionists to watermelon is far from unambiguous. Although it has high GI, a low amount of glucose enters the bloodstream when it is consumed. The glycemic load of the watermelon is small, and all because it is almost 90% composed of water, and there is very little carbohydrate in its pulp.
