High levels of insulin will suppress appetite, but fructose will not pull the trigger of insulin, so the brain will not get the message that it is full. This can explain why some people can unconsciously chew a piece of melon or eat so many grapes.
Fructose increases the probability of colon cancer: Fruits originally containing fructose are nutritious and beneficial to the stomach. However, after the fruit is squeezed into juice, these nutrients will also be squeezed dry. In addition, a large intake of fructose will increase the probability of people suffering from intestinal cancer.
Extended data:
Four types of people should not eat fructose:
One is people who are intolerant of fructose. Mainly due to the lack of B- aldolase, eating fructose can also cause the accumulation of 1- fructose phosphate, which consumes a lot of phosphate reserves in the liver and accelerates the glycolysis of milk, resulting in lactic acidosis and postprandial hypoglycemia. This disease is often self-limiting, that is, people who can't tolerate fructose will soon have a strong aversion to any sweets.
The second type is people with fatty liver and hypertriglyceridemia. Mainly because fructose is metabolized and absorbed quickly, it can be converted into triglycerides like glucose, especially if it is ingested too much, it will lead to fatty liver and hyperlipidemia.
The third is obese people. Mainly because fructose can reduce the sensitivity of human body to leptin. Leptin is a hormone that can regulate appetite, reduce food intake and increase energy consumption, thus losing weight. Because of the inhibitory effect of fructose on leptin, people who eat more fructose are more likely to overeat and lead to obesity.
Fourth, gout patients. The main reason is that excessive intake of fructose increases blood uric acid. Studies have found that people who consume more than 50 grams of fructose per day (equivalent to 2-3 cans of drinks) have a 2-4 times higher risk of hyperuricemia than those who consume less than 10 grams per day.
