Nutritionists and doctors have been saying for years to limit your consumption of red meat. Certainly I have been one of those and research on Mediterranean diet shows that limited consumption is best but this has never meant "don't eat red meat at all."
Much of the research has been based on studies that show an association between consumption of saturated fat and various diseases. Likewise, there are large studies that have shown similar links between red meat and heart disease as well as some cancers. In terms of nutrition, "red meat" includes unprocessed beef, pork and lamb. (Pork is NOT the "other white meat.") "Processed meats," on the other hand, include items such as hot dogs, salami, bacon and other cured meats. Recommendations that follow Mediterranean Diet guidelines suggest that you limit the amount of red meat you eat and instead eat more fish and vegetarian meals.
A recent study published in the journal Circulation takes a closer look at the connection between red meat, processed meats, and heart disease and diabetes. With funding from the Bill and Melinda Gates Foundation and the National Institutes of Health, among others, researchers from Harvard Medical School reviewed the data from 20 research articles of red and processed meat consumption and the link to heart disease and diabetes. These studies included over 1.2 million people who were tracked between 4 and 18 years and provided dietary and health information through detailed questionnaires, telephone interviews, or a combination of both.
The researchers grouped the respondents into rising levels of red meat consumption, from less than 1 serving per week to 1 or more servings per day. They also created similar groups for amounts of processed meats as well as a combination of both red meat and processed meats as a total.
Their findings are particularly striking:
