from Steve Edward's blog post about carnivores:
He quotes this study, which is extensive and large sample:
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.
People whose diets contained more white meat like chicken and fish had lower risks of death.
The researchers surveyed more than 545,000 people, ages 50 to 71 years old, on their eating habits, then followed them for 10 years. There were more than 70,000 deaths during that time.
