Diabetics can eat some lychee in small quantities if their blood sugar control is relatively stable, but it is not advisable to eat too much because lychee belongs to the high glycemic index food, and the carbohydrate content is also high, if the sugar lover wants to control the blood sugar smoothly, the amount of lychee consumed should be less than 80g, which is less than 2 taels.

Some claims that lychee can cause hypoglycemia, but this does not mean that diabetics can eat more lychee, because lychee contains a large amount of fructose, fructose by the gastrointestinal mucosa of the capillary absorption, it must be by the liver in the conversion enzyme into glucose, in order to be directly for the human body to use. If excessive intake of lychee, too much fructose into the human blood, "transformation" of fructose converting enzyme will be in short supply, resulting in a large number of fructose filled with blood vessels, but the conversion of glucose, resulting in the human body's blood glucose (glucose) content than the normal lower than the normal, which in turn causes hypoglycemia. But these lychee in the fructose later or to be utilized by the body, produce heat is not less, is bound to make the blood sugar rise, lychee is not a hypoglycemic effect, but can not be converted into glucose in a timely manner.

If a small amount of lychee, the body still has the ability to convert it into glucose in time, blood sugar will certainly rise. 60% of diabetics with hyperlipidemia, and the consumption of a large number of fructose will cause hyperlipidemia, resulting in a vicious circle.
