Women should eat more red meat to prevent breast cancer

　　Eating too much red meat can lead to at least some female Increased chances of breast and colon cancer. For this reason, researchers recommend that women should limit their red meat intake to less than 3 ounces per day.

　　Researchers studied more than 90,000 people menopause Preliminary studies followed women for 12 years. After controlling for other risk factors such as weight, alcohol consumption, and the amount of fruit and dairy consumed, the researchers found that women who reported eating at least one and a half servings of red meat per day were twice as likely to develop breast cancer as those who ate up to three servings of red meat per week.

　　Studies have shown that one reason why women who like to eat red meat are more susceptible to breast cancer is that carcinogenic compounds such as heterocyclic amines are produced during the high-temperature processing of red meat during grilling and frying, especially when it is poorly cooked. Heterocyclic amines have been found in laboratory studies to bind to estrogen receptors and create estrogen-like effects. Previous studies have also shown that postmenopausal women who regularly eat burgers, steaks and bacon are more than four times more likely to develop breast cancer than other women of the same age who eat less of these foods.

　　This new study also shows that heterocyclic amines may be more harmful to some people than others. Like many carcinogens, heterocyclic amines must be activated to damage DNA in the human body and constitute cancer The threat is that people with genes that activate heterocyclic amines more quickly are more likely to develop breast cancer than people with genes that activate heterocyclic amines more slowly.

　　Although both red meat and white meat produce heterocyclic amines when cooked at high temperatures, red meat contains more heme that is easily absorbed by the body. Research shows that heme may increase the risk of colon cancer by damaging the colon mucosa and accelerating the growth of cancerous cells. The researchers also said that heme may also react with estrogen to promote the development of breast tumors.

　　In addition, the relationship between eating more red meat and breast cancer also depends on the composition of red meat. Some studies have shown that eating too much red meat containing a lot of saturated fat can cause insulin levels to rise. Regardless of how sensitive women are to estrogen changes, rising insulin levels may accelerate the development of breast cancer cells.
