Every one serving increase of processed red meat per day was associated with a 20% greater risk of death over 22 to 28 years according to two studies analyzed by researchers from the Harvard School of Public Health in Boston, Massachusetts, USA.
Processed and Unprocessed Meats, and Serving Size
Processed and unprocessed meats, and serving size defined
“Questionnaire items about unprocessed red meat consumption included ‘beef, pork, or lamb as main dish’ (pork was queried separately beginning in 1990), ‘hamburger,’ and ‘beef, pork, or lamb as a sandwich or mixed dish.’”
The standard serving size was 85 g (3 oz) for unprocessed red meat.
“Processed red meat included “bacon” (2 slices, 13 [grams]), “hot dogs” (one, 45 [grams]), and “sausage, salami, bologna, and other processed red meats” (1 piece, 28 [grams] [one ounce]).”
Conclusion: Red meat increases the risk of dying for cancer, cardiovascular disease and the total risk of dying
“In conclusion, we found that greater consumption of unprocessed and processed red meats is associated with higher mortality risk,” the paper concludes.
“Compared with red meat, other dietary components, such as fish, poultry, nuts, legumes, low-fat dairy products, and whole grains, were associated with lower risk.
“These results indicate that replacement of red meat with alternative healthy dietary components may lower the mortality risk.”
