Sugar can be generally divided into monosaccharide, disaccharide and polysaccharide by molecule.
Monosaccharide (such as glucose, fructose, etc. ) is rich in fruit, sweet and fast to absorb, and can quickly enter the blood after eating.
Disaccharides (such as sucrose and maltose) also enter the blood soon after eating. Sucrose consists of one molecule of glucose and one molecule of fructose, and maltose consists of two glucose molecules, both of which contain glucose in the decomposition products in the body. Therefore, diabetics should not eat sugar.
Polysaccharide? Most of them exist in food in the form of starch, and another form is dietary fiber. The slow digestion and absorption of polysaccharide is beneficial to keep blood sugar stable. Therefore, diabetics should eat polysaccharide.
Ladies and gentlemen, if the human body wants to function normally, it definitely needs to ingest sugar. Just don't eat too much sugar and pay attention to its sugar content in your daily diet. For example, you shouldn't touch sweets. And foods rich in dietary fiber such as sweet potatoes and apples. It can not only ensure the blood sugar balance of diabetic patients, but also avoid the poor performance of fatigue caused by insufficient blood sugar. Fructose in monosaccharide, now there are products selling fructose separately on the market, which is the gospel of diabetic patients. Fructose is tailor-made for diabetics. The effect of fructose on human body?
(1) Fructose is metabolized in the human body without insulin, and directly enters the intestine to be digested and utilized. The GI value of fructose is low, which is less than 1/3 of sucrose and 1/2 of honey, and tends to the ideal value of natural sugar, with low glycemic index and no burden on blood sugar.
(2) Fructose is not easy to be converted into acid by streptococcus in oral cavity, which can inhibit bacteria from producing dextran, thus inhibiting the generation of dental caries; (3) The sweetness of fructose is 1.2- 1.8 times that of sucrose. Under the same sweetness, it can effectively reduce sugar intake and fat accumulation and achieve the effect of weight control.
