What is red meat, usually refers to beef, pork, lamb and other livestock animal meat is called red meat; while the fish, poultry meat is called white meat. Red meat is characterized by thick and hard muscle fibers and high saturated fat content, while white meat has delicate muscle fibers, low fat content and high unsaturated fatty acid content in fat. On October 26, the International Agency for Research on Cancer (IARC), which is affiliated with the World Health Organization (WHO), officially released the news that processed meat products are cancer-causing foods, and that various red meats are 2A cancer-causing foods. This news almost broke the screen in various media. They are based on epidemiological findings that the development of colon and rectal cancer is associated with the consumption of too much red meat or processed meat, which means that the consumption of too much red meat or processed meat increases the risk of developing colon/rectal cancer. Animal studies have also long shown that the effects of many carcinogens may be enhanced in the presence of too much animal protein and fat. Also, too much red meat food has a detrimental effect on the balance of colonic flora, and the proliferation of some harmful bacteria can produce cancer-causing metabolites. However, animals themselves are divided into three categories: carnivores, herbivores and omnivores. Carnivores and omnivores need meat, including red meat, or they cannot survive. Humans are omnivores and animals at the top of the food chain, and many nutrients must be provided through the ingestion of red meat. So red meat can be considered an essential food source for humans. Of course, a series of clinical epidemiological studies have revealed that excessive consumption of red meat is a high risk factor for certain tumors, but it is only a high risk factor. The survival of human beings cannot be separated from red meat. In the adult population, it is important to avoid excessive consumption, while in the pediatric population, or in those with certain diseases (such as iron deficiency anemia), it is important to encourage more red meat consumption. For example, for people in growth and development, pregnant women (fetuses), children and adolescents, red meat is one of the best sources of protein due to growth and development, and is also the best source of essential nutrients such as iron, zinc, copper, selenium and multivitamins, so children and pregnant women need to eat more red meat. For adults, it may be necessary to control the intake of red meat, but it is definitely not a rejection of red meat. The high incidence of anemia that many women experience is the need to increase red meat in the diet to replenish iron and other elements. Therefore, there is no need to make a fuss about the issue of red meat causing cancer. The eat still have to eat, the encouragement to eat still have to encourage, just adults, do not eat too much, eat too much to lose weight, and the risk of colon / rectal cancer Oh!
