The so-called "starch blocker" should refer to an amylase inhibitor. In human body, amylase breaks down starch into sugar, and some sugar that cannot be absorbed directly is broken down into sugar that can be absorbed directly by some glycosidase. So starch needs amylase and glycosidase to digest and absorb. (In fact, amylase should be a kind of glycosidase. Amylase inhibitors generally include: sugars (and analogues), protein (and peptides), others (soy isoflavones are really everywhere, and tea leaves and so on). Some amylase inhibitors also inhibit glycosidase. Therefore, we can delay the digestion and absorption of starch and sugar by inhibition and maintain satiety. Theoretically, it can be used for diseases related to high sugar and high calorie, such as diabetes, obesity, arteriosclerosis and hyperlipidemia. Because of its small molecular weight, sugar is more stable to heat and enzymes, and has higher value from the perspective of drug development. Protein is specific and helpful to scientific research. The outstanding representative of sugar is acarbose, which has been used in diabetes in clinic. Other species have also been studied. Amylase inhibitors are more effective than placebos as weight-loss drugs in foreign clinical research. I don't know if it's listed. Animal experiments show that it can effectively reduce blood lipid and prevent atherosclerosis. Some people think that amylase inhibitors have potential in the field of health care products. Page 65438 +0. Transgenic insects can be used to resist insects in agriculture, but it has nothing to do with this problem. 2. Its application in pancreatitis has also been studied in medicine, but it has nothing to do with this subject. . This should be the focus of this answer, but I am sleepy ... Let me remind you that overweight/obesity or high-calorie diet was used in the study. About "70%", I personally think it is only used for advertising.
