In the past, most women would choose dieting in order to lose weight, but now women will choose crude fiber food as their staple food in order to lose weight healthily. So what is crude fiber food? I'll introduce it to you today.
0 1 crude fiber is the main component of plant cell wall, including cellulose, hemicellulose, lignin and keratin. The main consumers of crude fiber food should be adults and the elderly. When eating, it should be based on the recommended intake of crude fiber in nutrition, 20~35 grams per person per day. Eating more will reduce the utilization rate of other nutrients.
Crude fiber cannot be digested and absorbed by human body. Before 1970, there was only "crude fiber" in nutrition, which was used to describe undigested and absorbed food residues, including only some cellulose and lignin. It is generally believed that crude fiber has no nutritional effect on human body, and even eating too much will affect the absorption of nutrients in food, especially trace elements.
After a series of investigations and studies, we realize that those "non-nutritive" substances that cannot be digested and absorbed by human body are closely related to human health and play an important role in preventing some human diseases such as coronary heart disease, diabetes, colon cancer and constipation. At the same time, we also realized that the concept of "crude fiber" was no longer applicable, so we abandoned it and changed it into dietary fiber.
Modern nutrition research shows that eating crude fiber food has four advantages: first, it can promote intestinal peristalsis, help the human body accelerate metabolism, improve gastrointestinal function, prevent constipation and prevent intestinal cancer; Second, improving blood glucose response and reducing postprandial blood glucose content are helpful to treat diabetes; The third is to reduce the content of cholesterol in plasma and prevent hyperlipidemia and cardiovascular diseases; The fourth is to control weight and reduce the occurrence of obesity.
Crude fiber can also increase the volume of feces, reduce the time for food residues to stay in the intestines and speed up the frequency of defecation, so children and people with poor gastrointestinal function and frequent diarrhea should not eat more.
