Lychee is so sweet because it has more than 16% sugar content, but most of it is fructose. Fructose cannot be absorbed directly by the body, but needs to be converted into glucose through the action of enzymes. "Sugar lovers" eat too much at once, will lead to the enzyme work is not over, thus the lack of glucose. This is what we often call hypoglycemia, which is also known as "lychee disease" in common parlance.

See here, there may be a lot of "sugar" people feel happy, think this is not just suitable for high blood sugar people to eat? But you have to know, low blood sugar is not the same as lower blood sugar, this is actually a lot of people will fall into a misunderstanding. Eating too much lychee at one time, resulting in a significant drop in blood sugar in a short period of time, causing fluctuations in blood sugar, in fact, on the contrary, it is not conducive to blood sugar to remain stable. In addition, from a certain point of view, the harm of hypoglycemia in fact do not have to high blood sugar is not small, serious impact on the body is also very big.
