Colon cancer is a very common malignant tumor of the intestine. The number of new colorectal cancers per year in China has reached 120,000, and it has been rising at an average annual rate of 4.2%. China has become a high-risk area of ​​colon cancer. Experts said that they can eat more dietary fiber to prevent colon cancer.

Why dietary fiber can prevent bowel cancer?

Before 1970, there was no word for dietary fiber in nutrition. At that time, only the concept of crude fiber was considered and it was considered useless as a nutritional supplement. In the 1970s, experts proposed the dietary fiber hypothesis and suggested that many modern human “civilized diseases” are related to eating too little dietary fiber. Coarse grains and foods containing many dietary fiber can prevent many common diseases such as colorectal cancer and high fat. After anemia, heart disease, constipation, obesity, and diabetes, dietary fiber became the focus of experts and began research. Crude fiber was also changed to dietary fiber and became an important nutrient for human health.

It is understood that dietary fiber is divided into two categories: water-soluble dietary fiber and water-insoluble dietary fiber. Water-soluble dietary fibers include polydextrose, low-fat pectin, fructo-oligosaccharides, malto-oligosaccharides, high-fat pectin, etc., and are most commonly found in foods such as barley, oats, flax, citrus, beans, carrots, oat bran, etc. Can delay digestion and excrete cholesterol most quickly, so blood glucose and cholesterol can be controlled at optimal levels

Non-water-soluble dietary fiber is a common plant cell wall composition, including cellulose, hemicellulose, and lignin. In foods, wheat bran, corn bran, celery, enoki mushroom, pericarp, and rhizome vegetables are the most important. It can help stool. Forming, stimulate intestinal peristalsis, strengthen defecation, prevent constipation.

Experts said that the reason why dietary fiber can effectively prevent colorectal cancer is because dietary fiber has strong water absorption, which can increase the volume of feces and facilitate the excretion of feces, which can shorten the residence time of feces in the intestine and reduce cancer Contact with the intestinal wall reduces the concentration of carcinogens in the intestine, thereby reducing the risk of colon cancer.

Experts advise: The more dietary fiber intake, the better!

Since dietary fiber is so useful, is it better to eat more? Experts said that excessive dietary fiber not only affects gastric power, impedes food digestion, but also causes nutrients to be difficult to absorb and causes malnutrition. In addition, if excessive intake of water-insoluble dietary fiber, it may cause increased stool volume, shape stiffness, difficult to excrete, and even increase constipation, but become a hidden danger of colorectal cancer.

According to the recommendations of the China Nutrition Society, the average daily energy intake (2400 kcal/d) of the population is kept at 25-30 g/day. Dietary fiber intake structure, according to the recommendation of Japanese nutritionists, the ratio of water-soluble dietary fiber and water-insoluble dietary fiber should be around 2:1.
