Lychees are very sweet and give people the impression that they are high in calories. Lychees are sweet because they contain 15.23 grams of sugar per 100 grams, higher than bananas.

It's not that high in energy, though. Litchi has about 71 kcal per 100 grams. A medium-sized lychee has about 10 kcal of energy. We eat nine lychees for the equivalent of one piece of toast.

GI refers to the glycemic index of some foods. Simply put, the higher the GI, the faster the blood sugar levels in the body rise after eating. Litchi, though sweet, is not a high-GI food. It has a GI index of only 57, making it a mid-GI food.

Litchi so sweet, how GI index is not high? This is because it contains about two-thirds of the sugar, the fast-rising glucose and sucrose, and another third, the slow-rising fructose. In addition, it contains hypoglycine A and α-methylcyclopropylglycine, which have hypoglycemic effects.

If we eat a large amount of litchi at a time, a large amount of fructose will accumulate in the blood vessels, resulting in a "short supply" of invertase, unable to timely convert fructose into glucose.

At the same time, fructose stimulates the body to produce large amounts of insulin, which causes the liver to lower blood sugar levels, resulting in insufficient glucose supply in the blood.

In addition, when a large amount of litchi is consumed, the intake of other foods is reduced, further reducing the glucose supply, thus causing hypoglycemic symptoms. Sometimes they even have nausea, sweating, and fatigue, which can cause convulsions or coma.
