Red meat is listed by WHO as a carcinogen, experts: not talking about "safe dose" is a hooligan

In the cold winter, the most happy is to eat a hot pot.
Fat cow, fat sheep, pork balls, all kinds of meat, there is always a way to satisfy your taste buds, and then drink a bowl of steaming broth, can always make people feel endless comfort and warmth ... But a recent study in the british medical journal BMJ has led many people to be wary of meat - red meat and processed red meat eat too much, the higher the risk of coronary heart disease! BMJ: Eat 1 serving of red meat a day, coronary heart disease to knock on the door so-called "red meat", is the appearance of red meat, we usually eat beef, pork, lamb and other mammalian meat, all belong to red meat.
and "processed red meat" refers to smoked, marinated red meat, such as sausage, bacon, ham, canned meat and so on.
study, the Harvard team followed 43,272 American men between 1986 and 2016 who had no cardiovascular disease or cancer before the study, with an average age of 53.
researchers surveyed participants every four years to record their dietary type and frequency, as well as their lifestyle, such as smoking, physical activity, etc., to update known or potential risk factors for coronary heart disease.
4,456 people developed coronary heart disease during the 30-year follow-up period.
the researchers found that the more red and processed red meat they ate, the more likely coronary heart disease was to occur.
Through multivariate adjustment of dietary and non-dietary risk factors, it was shown that the risk ratio of coronary heart disease was 1.12, 1.11, 1.15, i.e. the risk of coronary heart disease increased by 12%, 11% and 15%, respectively.
the result not very bereavement? However, the researchers found problems and proposed solutions.
study also showed that eating one serving of plant protein a day, a combination of nuts, legumes and soy, reduced the risk of coronary heart disease compared to red meat.
, replacing total red meat with whole grains and dairy products and processing red meat with eggs can also reduce the risk of coronary heart disease.
red meat not only "sad", but also carcinogenic? Numerous randomized trials and observational studies in the past have shown that eating too much red and processed red meat can increase mortality and the risk of chronic diseases, and may even cause cancer.
years ago, red meat was classified as a Category 2A carcinogen by the International Agency for Research on Cancer (IARC), part of the World Health Organization.
processed meat is included in the "class 1 carcinogens", said that eating 50g of processed meat a day, colon cancer risk increased by 18%, which made people panic.
red meat is both sad and carcinogenic, if you want to have a healthy body, is not to "drop meat do not touch", to be a vegetarian? What a cruel thing it is for carnivores! However, we do not have to panic, carcinogens are graded, "class 1 carcinogens" is a solid evidence of carcinogenic substances, and "class 2A carcinogens" refers to: the human is likely to cause cancer, but the evidence of human cancer is limited, the experimental animal carcinogenic evidence is sufficient.
that is to say, bacon, sausages and other processed meat we have better not eat, no processed fresh red meat, do not over-ingest every day can be, the right amount to eat no big problem.
addition, red meat is a double-edged sword, there are disadvantages and advantages.
red meat has its nutrients, containing protein, iron, zinc, vitamins and other essential nutrients, we do not completely reject.
, because chronic diseases are the result of a combination of factors, such as smoking, staying up late, genes, etc., red meat is only one of the risks, we can not completely let it "back pot."
Also, eating red meat does not necessarily cause coronary heart disease or cancer, BMJ's research and WHO statements only suggest that there is such a correlation, that it is not sick, that it is not carcinogenic, but that it is only a matter of time and "dose".
you eat red meat to be healthy? 1, pay attention to intake, don't eat too much "don't look at the dose is playing hooligans", drink too much water are harmful to health! If you want to eat red meat healthy, you must control your intake.
According to the dietary guidelines of our residents, the recommended daily intake of livestock and poultry meat per person is 40-75g, the weekly intake is 280-525g, as long as it is not excessive, there is no big problem.
, diet should pay attention to nutritional balance, eat more vegetables, fruits, help reduce the risk of disease.
2, pay attention to cooking methods to cook meat food, the recommendation is to cook with water, steaming, low-temperature stew and other ways, do not fry, fry, barbecue, so as not to produce nitrites, benzeneand other carcinogens in the cooking process, in recent years, the network of all kinds of negative news about red meat, red meat cancer reports are not uncommon.
, however, humans are animals at the top of the food chain, we can not therefore "talk about meat color change", as long as the control of intake, pay attention to cooking methods, healthy eating meat, can do it! 39 Health.com Source: 39 Health.com Copyright Notice: All text, images and audio and video materials on this website that indicate "Source: Mets Medicine" or "Source: MedSci Original" are owned by Mets Medical, and are not authorized to be reproduced by any media, website or individual, and are authorized to be reproduced with the words "Source: Mets Medicine".
