Wake up, "white kidney beans" can't help you "Hey, eat" is not fat
2022-05-09
It's not just carbohydrates that make us grow meat. In contrast, various sugars added to refined foods are the main reason for the failure of weight loss, and the human body does not need amylase to absorb these sugars. Therefore, it is not scientific to lose weight only by carbon water blockers. It is just a helper for us to move towards health, not an excuse to indulge in "Hi eating". Dong Haiyun, director of clinical nutrition center of Affiliated Hospital of Qinghai University The weather is getting hotter and it's weight loss season again. A carbon water blocker product containing "white kidney bean extract" appears on many e-commerce platforms. It has been labeled as "big meal savior" by some weight loss bloggers. The manufacturer said that taking it before eating staple food can block the absorption of high-carbon water food and help stabilize blood sugar. So what is "white kidney bean extract"? Can it really help us "block" carbohydrates? In response to the above problems, the reporter of science and technology daily interviewed relevant experts. Only a small part of carbon and water absorption can be blocked Data show that the biological name of white kidney bean is kidney bean. As a vegetable, it is called kidney bean. It belongs to the kidney bean genus of butterfly flower subfamily, one of the three subfamilies of Leguminosae. "White kidney bean extract is rich in α- Amylase inhibitor (hereinafter referred to as amylase inhibitor) can inhibit α- The activity of amylase reduces the activity of amylase in human mouth and pancreas, and plays the role of inhibiting salivary amylase and pancreatic amylase, resulting in that starch cannot be completely decomposed into small molecule monosaccharides and absorbed by human body. " Dong Haiyun, director of the clinical nutrition center of the Affiliated Hospital of Qinghai University, said in an interview with the science and Technology Daily that since the substance is extracted from plants or contains some plant lectins, it may increase the level of some hormones in the human body and slow down the speed of gastric emptying after meals. So it sounds like it can really make people "Hey, don't eat fat". Is that true? Research data show that under ideal conditions, amylase inhibitors can inhibit amylase activity by 50% to 65%. "However, it should be noted that the remaining 35% of amylase that is not inhibited is enough for the human body to fully absorb the starch contained in a meal. Even the strongest amylase inhibitor can only inhibit 97% of amylase activity at a safe dose. Unfortunately, according to the data of this study, it has only helped people reduce starch intake by 7%." Dong Haiyun said. At the same time, Dong Haiyun said that the human body absorbs starch not only by amylase, but also other "colleagues" to help it share the work, so even if the amylase activity is completely inhibited, it can not do zero intake of starch. "In addition, it's not just carbohydrates that make us grow meat. In contrast, the various sugars added to refined foods are the main cause of weight loss failure, and the human body doesn't need amylase to absorb these sugars." Dong Haiyun said that it is not scientific to lose weight only by carbon water blockers. It is just a helper for us to move towards health, not an excuse to indulge in "Hi eating". In addition to helping to lose weight, carbon water blockers can also reduce blood sugar, so many patients with diabetes are also competing to buy them. "It is best for diabetes patients to take carbon water blockers after meals, which can inhibit starch absorption, reduce the increase of blood sugar, and then play a role in stabilizing the disease. However, diabetes patients must take them under the guidance of professional doctors, and do not buy and use them by themselves." Dong Haiyun added. Excessive or prolonged hypoglycemia Compared with its weight loss and hypoglycemic effects, many consumers are more concerned about the edible safety of carbon water blockers. Dong Haiyun said that as a pure natural bioactive substance, amylase inhibitor will be discharged from the body through the gastrointestinal tract without entering the blood circulation system and acting on the brain center after entering the human body. Therefore, it will not inhibit appetite, which is in line with the weight loss principle of the World Health Organization and has been approved by the Ministry of health. It can be used as ordinary food or added to dietary supplements, beverages or pet food. "However, if long-term and excessive use of amylase inhibitors may lead to physical fatigue, depression and other problems. In serious cases, it may also lead to hypoglycemia and more discomfort symptoms, such as anemia, syncope and so on." Dong Haiyun warned, "generally speaking, it is safe to take no more than 10 grams of amylase inhibitors every day. However, taking amylase inhibitors may lead to flatulence, diarrhea and other intestinal problems. People who are prone to flatulence and diarrhea should use them with caution." (outlook new era)
