创新英语-Red Meat Increases Risk of Cancer
Health authorities in Britain have advised against eating too much red meat. The British government has issued a set of red meat guidelines which caution against eating more than 500 grams a week, or 70 grams a day. This is the equivalent of two beef burgers. Scientists say that eating more than this increases the risk of getting colon 1 and bowel 2 cancer. The new limits are down on the 90 grams a day recommended in 1998. Researchers think people who eat a lot of meat like lamb, beef, ham and bacon have a higher risk of cancer. A 2005 European study found people who ate about 160 grams of red meat a day increased their bowel cancer risk by one third compared to people who ate little meat. People have around a one in 19 chance of developing bowel cancer in their lifetime.
Experts told people the new guidelines did not mean people had to abandon red meat. The head of health information at Cancer Research U.K. said: "This doesn't mean people have to become vegetarian 3, but if you're having a steak every day, that's probably not helping 4.” Scientists are unsure as to why red meat increases the risk of colon cancer. They suspect that haem, the pigment 5 that gives meat its colour, damages the cells in the digestive system and the lining 6 of the colon. A World Cancer Research Fund official said: "Following simple diet and lifestyle advice can help protect against cancer. Red meat can be part of a healthy balanced diet. It is a good source of protein and vitamins and minerals…But people who eat a lot of red and processed meat should consider cutting down.”
