Why can konjac suppress appetite and lose weight?
Amorphophallus konjac is rich in dietary fiber, protein, amino acids, minerals, alkaloids and other nutrients, and is one of the top ten health foods identified by the World Health Organization. However, the whole plant of Amorphophallus konjac is poisonous and cannot be eaten raw. It can only be eaten after processing.
The main component of konjac after processing is glucomannan (KGM), and the refined powder generally contains more than 65% glucomannan, and the glucomannan content in refined powder can reach about 80% by lifting technology. Glucomannan, as a kind of natural polymer water-soluble dietary fiber, has low calories and has many benefits for weight loss.
Glucomannan has good water absorption and expansibility. As long as 2~3 grams of konjac flour comes into contact with water, it can expand into a translucent viscous liquid of about 200 grams. Therefore, eating konjac products rich in glucomannan is easy to make people feel full, delay the time of gastric emptying, and thus reduce food intake.
Glucomannan, like other dietary fibers, can also promote gastrointestinal peristalsis, and can also "incidentally" absorb some toxic and harmful substances and excessive cholesterol and fat, and excrete them with feces, which is helpful for relaxing bowels.
Glucomannan can be degraded into short-chain fatty acids (SCFA) by microbial fermentation in large intestine. Short-chain fatty acids can act on hypothalamus by stimulating L cells in intestinal mucosa to secrete hormones, which ultimately reduces hunger and inhibits people's appetite.
What are the nutritional values of konjac?
Konjac is extremely rich in nutritional value. Besides abundant plant-specific dietary fiber, it is also rich in protein, fat, starch and carbohydrates, as well as various trace elements such as calcium, phosphorus, iron, zinc, manganese and cobalt. In addition, it contains 17 amino acids, 8 of which are essential for human body.
1, reduce fat and blood sugar.
Konjac can reduce blood fat, which is a good choice for people with dyslipidemia. Amorphophallus konjac is eaten into the body, and its rich ingredients will inhibit the absorption of fat in the body, so that the fat in the body will be digested quickly, but too much will stay in the body. Moreover, konjac can also delay the absorption of sugar by human body and inhibit the absorption of sugar by gastrointestinal tract, so it also has the function of lowering blood sugar and keeping the blood sugar level within the normal range. Therefore, patients with dyslipidemia and diabetes can take konjac.
2, detoxification and laxative.
Amorphophallus konjac is rich in dietary fiber, which can help our gastrointestinal digestion, promote intestinal peristalsis, and efficiently discharge excess fat and garbage accumulated in the body, so it can also play a laxative role for people with constipation.
3. Improve immunity.
When konjac is heated with water, a gelatinous film will appear. When people eat it, this film will be adsorbed on people's intestines. Then, when we eat other foods, the film will well prevent the intestines from directly contacting toxic substances. Will play a protective role, reduce the burden on the stomach, hinder the absorption of toxic substances, thereby improving human immunity.
4. Calcium supplementation.
Konjac also contains natural calcium, which will lead to the normal development of bones when we lack calcium. The calcium contained in konjac can be well absorbed by human body and can promote the development of human bones. For the elderly, it can also prevent osteoporosis and slow down the loss of calcium.
