The largest study of its kind finds that older Americans who eat large amounts of red meat and processed meats face a greater risk of death from heart disease and cancer.
The federal study of more than half a million men and women bolsters prior evidence of the health risks of diets laden with red meat like hamburger and processed meats like hot dogs, bacon and cold cuts.
Calling the increased risk modest, lead author Rashmi Sinha of the National Cancer Institute said the findings support the advice of several health groups to limit red and processed meat intake to decrease cancer risk.
The findings appear in Monday’s Archives of Internal Medicine.
Over 10 years, eating the equivalent of a quarter-pound hamburger daily gave men in the study a 22 percent higher risk of dying of cancer and a 27 percent higher risk of dying of heart disease. That’s compared to those who ate the least red meat, just 5 ounces per week.
Women who ate large amounts of red meat had a 20 percent higher risk of dying of cancer and a 50 percent higher risk of dying of heart disease than women who ate less.
For processed meats, the increased risks for large quantities were slightly lower overall than for red meat. The researchers compared deaths in the people with the highest intakes to deaths in people with the lowest to calculate the increased risk.
So watch out for how much red meat you eat. If you have concerns, contact your dietician, health care physican or nurse.
