The Calgary Herald published an article on a study the showed that eating red meat in increase your risk of dying, dying earlier than not eating or eat less red meat. In an article entitled Live longer by reducing red meat intake: Study, Sharon Kirkey reported that those who eat an average of 1 3/4 lb per week of red meat have a high change of dying from heart disease or cancer than those who consume only 1/2 lb of red meat per week. Canadian Cancer Society, which led the study, would lower its recommended amount of red meat to 18 oz per week.
The study, which was published in Archives of Internal Medicine entitled Meat Intake and Mortality, was done on 322,263 men and 223,390 women aged between 50 to 71 lived in 1995. 10 years later, a follow up study was done in 2005 and found that about 48,000 men and 23,000 women have died.
Men with high red meat intake has a 31% higher risk of death as compared to those with low red meat intake. Women, however, have 36% higher risk of death. All these findings are with family history, smoking, body mass and other risk factors worked in. WOW! That's 11% deaths in men and 16% deaths in women that are attributed to high red meat intake.
Let me try to put in a graph format:

Remember these percentages are the comparison of those with high red meat intake (1 3/4 lb per week) and with those with low red meat intake (1/2 lb per week).
The study also did a comparison on processed meat and its affect on death. I will go straight to the graph.

Before I go on, the term "Red Meat" and "Processed Meat" should be clearly defined.
Red Meat: bacon, beef, cold cuts, ham, hamburger, hot dogs, liver, pork, sausage, steak and meats in foods.
Processed Meat: bacon, red meat sausage, cold cuts, ham and regular hot dogs.
Ok, here's the last type of meat: white meat.
White Meat: chicken, turkey, fish, poultry cold cuts, canned tuna, low-fat sausages and poultry hot dogs.
Back to the study. Here's the interesting part of the study. The quantity of intake of white meat has "an inverse association for total mortality and cancer mortality as well as all other deaths for both men and women." Though no exact risk percentage were given, it seems like it is saying that the more white meat we eat, the healthier we are?
On a side note, there are a lot of studies Archives of Internal Medicine with red meat.
- A study on Red Meat Intake and Risk of Breast Cancer Among Premenopausal Women concluded that higher red meat intake may be a risk factor for ER+/PR+ breast cancer among premenopausal women.
- A study led by Dr Teresa T. Fung on Dietary Patterns, Meat Intake and the Risk of Type 2 Diabetes in Women concluded that a diet high in processed meats may increase the risk of type 2 diabetes in women.
- A study comparing the lipid-lowering effect of lean meat diets and that of vegetarian diets concluded that lean meat diet virtually have no lipid-lowering effect at all.
- Dr Teresa T. Fung also did a study entitled Adherence to a Dietary Approaches to Stop Hypertension (DASH)-Style Diet and Risk of Coronary Heart Disease (CHD) and Stroke in Women concluded that DASH-Style Diet does lower the risk of CHD and stroke among middle-aged women during 24 years of follow-up.
- Another Dr Teresa T. Fung study showed there is a significant positive association between the Western dietary (high intake of red and processed meats, sweets, and desserts, french fries and refined grains) and the risk of colon cancer.
