As physicians we recognize that lean meats may be a healthy part of almost anyone’s diet. However, based on the preponderance of evidence compiled by scientists and health experts across the globe, there is little doubt that a diet high in red and processed meats is linked to serious health risks and that we would all be wise to keep our consumption down. New dietary guidelines, recently released by the United Kingdom’s Scientific Advisory Committee on Nutrition (SACN) bolsters this conclusion. The SACN’s Iron and Health 2010 report advises that Britons can reduce their risk of colorectal cancer while maintaining healthy levels of iron by keeping their red meat and processed meat consumption to 70 grams or about 2 ½ ounces a day.
Cutting back on red and processed meat could do more than just ward off colorectal cancer. Research has linked it to other diseases such as diabetes, cardiovascular disease and even Alzheimer’s. A landmark United State’s study, published in 2009 in the Archives of Internal Medicine, Meat Intake and Mortality, which included data from more than half a million members of the AARP, concluded red and processed meat intakes were associated with modest increases of “total” mortality in addition to cancer and cardiovascular disease mortality. An equally important Harvard study, published in Circulation in 2009, that followed more than 84,000 female nurses, found that red meat intake increases the risk of coronary heart disease. More importantly researchers concluded that shifting sources of protein from meat based to plant based could reduce the risk of coronary heart disease.
The Washington Post reports that cutting down on red meat could save an estimated 3,800 Britons from dying of bowel cancer every year. However, SACN researchers made it clear that their report did not address other potential health risks associated with meat consumption, which means many more lives could be saved from other preventable diseases.
