Professor Zhou Chaofan, a member of the expert committee of the Chinese Academy of Traditional Chinese Medicine, affirmed that eating lychee is not a cure for diabetes. Lychee contains a large amount of fructose, fructose can only be utilized by the human body through the liver's conversion enzyme converted to glucose. Eat a lot of lychee, fructose accumulation in the blood vessels, too late to convert into glucose, so that the blood glucose is too low, thus causing hypoglycemic shock. However, it can not be said that, you can eat lychee to reduce blood sugar, because the consumption of large amounts of fructose will cause high blood lipids, more than 60% of diabetic patients with hyperlipidemia, so that the sugar is not consumed through the tricarboxylic acid cycle will be turned into triglycerides, triglyceride high people are not suitable for a large number of high fructose-containing foods. Professor Zhou said, as early as 1964, the Chinese Journal of Internal Medicine has reported two cases of hypoglycemic shock caused by eating a lot of lychee.
