For a long time, fructose has been promoted as a "healthy sugar," but it may suppress the brain's production of satiety signals, leading to overeating and consequently causing weight gain.
Food experts explain that fructose is found in natural foods such as fruits and honey. Additionally, high-fructose corn syrup, as a significant sweetener, is now widely used in the processing of foods like fruit juices, cold drinks, preserved fruits, and jams.
Food experts say that there were indeed reports in the past indicating that for diabetic patients, blood glucose and insulin levels did not change significantly after consuming fructose compared to glucose, which is why some people called it a "healthy sugar." However, in recent years, many studies have shown that foods rich in fructose can increase the risk of obesity and diabetes, and also加重 the burden on the liver, raising the risk of developing fatty liver. For instance, in daily life, replacing other carbohydrates (such as sucrose, rice, and flour) with fructose (especially artificial fructose) can also increase the risk of gout and cause lipid metabolism disorders. Unlike beverages, fruits contain much lower levels of fructose and also have a large amount of beneficial components such as vitamins and dietary fiber, which can mitigate the potential harm of fructose.
