Avoid Processed Meat To Prevent Heart Disease!

Bacon, sausage, hot dog and some other processed meat have already become an integrated part of many meat lovers’ diets. But many are probably not aware that eating too much of these would raise their chances of developing diabetes and heart disease.

In a paper published on May 17, 2010 in the journal ‘Circulation’, researchers from Harvard School of Public Health reported that eating unprocessed beef, pork or lamb did not seem to raise risks of heart attack and diabetes. Therefore, salt and chemical preservatives are the real culprits responsible for these 2 health disorders.

Many past studies examining the relationship between eating meat and cardiovascular disease and diabetes had found mixed results, and few had looked at the differences in risk between processed and unprocessed red meat.

To get evidence of a link between eating processed and unprocessed red meat and the risk of diabetes and heart disease, a systemic review of nearly 1,600 studies from around the world were carried out.

Processed meat was defined in the study as any meat preserved by smoking, curing or salting, or with the addition of chemical preservatives. Good examples of processed meat included bacon, salami, sausages, hot dogs or processed deli or luncheon meats. On the other hand, unprocessed red meat included beef, lamb or pork but not poultry.

The findings showed that on average, every 50 grams serving of processed meat a day (equivalent to 1 or 2 slices of deli meats or 1 hot dog) was associated with a 19 percent higher risk of developing diabetes and 42 percent higher risk of heart disease. Meanwhile, they found no higher risk of diabetes or heart disease in people eating only unprocessed red meats.

Hence, they urged people to eat less (1 serving or less per week) processed meats such as bacon, salami, sausages, hot dogs and processed deli meats in order to lower the risk of diabetes and heart attack.

As expected, the American Meat Institute objected to the findings quoting that it was only one study that was different from other studies and the United States Dietary Guidelines for Americans. Hence, there is no reason for dietary changes unless further studies could justify so.

Is Risk of Death Raised by Eating More Red Meat?

Is eating red meat bad for health? This highly controversial question has been debated between various groups of people for years.

Eating too much meat would probably cause people to put on weight. Being overweight or obese, one will have a much higher chance of getting many medical complications like heart disease, diabetes, high blood pressure, stroke and even certain types of cancer.

In order to find out answer pertaining to this question, the National Cancer Institute in United States carried out one of the largest study.

The researchers reported that people who eat the most red meat as well as processed meat have the highest overall risk of death from all causes, including heart disease and cancer. Their findings appeared in the Archives of Internal Medicine on March 23, 2009.

More than 500,000 people aged between 50 and 71 were involved in the study. They filled out questionnaires on their diet and other health habits. Their records were later examined by the researchers.

It was found that people who ate meat heavily were more likely to die over the next 10 years than those who ate the least amount of meat, even when other factors such as eating fresh fruits and vegetables, exercise, obesity and smoking were accounted for.

The researchers found that the consumption of red and processed meat were associated with modest increases in total mortality, cancer mortality, and cardiovascular mortality.

The volunteers participated in the study were divided into 5 groups, called quintiles. There were 47,976 men and 23,276 women died during the period between 1995 and 2005.

People in the quintile that ate the most red meat had a higher risk for overall death, death from heart disease and cancer than the men and women who ate the least red meat.

If people could eat less meat, thousands of deaths could just be prevented. For overall mortality, 11 percent of deaths in men and 16 percent of deaths in women could be prevented should people reduced their red meat intake to the level in the first quintile.
