Amorphophallus konjac has also been identified as one of the top ten health foods by the United Nations Health Organization. According to Compendium of Materia Medica, our ancestors used konjac to treat diseases more than 2000 years ago. Amorphophallus konjac contains 16 kinds of amino acids, 10 kinds of mineral trace elements and rich dietary fiber, which has special effects on preventing and treating diabetes and hypertension. Konjac is low in calories, fat and sugar. It can be said that it is an excellent food for preventing and treating colon cancer, breast cancer and obesity, and it can also prevent and treat many common chronic diseases of gastrointestinal digestive system. It can be seen that konjac is a kind of "God-given medicine", which is beneficial and harmless to eat. Amorphophallus konjac contains a gel-like chemical, which has the magical power to prevent cancer. As long as the mature konjac is simply extracted and separated into refined konjac powder, and then the refined powder is heated with water, konjac gel can be produced. This kind of gel can form a translucent film coating after people eat it, which adheres to the intestinal wall and hinders the absorption of various harmful substances, especially carcinogens. Therefore, konjac is also called "anti-cancer magic coat".
