Red Meat Boosts Risk Of Stroke

Eating more red meat increases the risk of stroke, according to a new meta-analysis by researchers in Poland and Sweden. Previous research on meat and stroke risk has shown a range of results, so scientists combined 6 studies totaling 329,495 participants and 10,630 cases of stroke to obtain more definitive answers.

The researchers concluded that each additional one serving per day of red meat was associated with an 11%-13% greater risk of stroke. The added risk was indicated entirely in ischemic stroke, the most common kind, and not in hemorrhagic stroke.

All types of red meat, including fresh meat, beef, steak, as well as processed meats such as bacon and sausage, and pork (also known as “the other white meat“), were linked to extra stroke risk; Not surprisingly, processed meats were linked to 13% greater risk per extra daily serving.

Research scientists involved in the study speculated that meat could increase overall stroke risk, because of its high saturated fat content, oxidative stress associated with iron in meat, as well as the commonly used preservatives in processed meats. .

Red Meat Consumptio​n Linked to Increased Risk of Cardio Disease and Cancer

In a new study from Harvard School of Public Health (HSPH) researchers have found that red meat consumption is associated with an increased risk of total, cardiovascular and cancer mortality. 

The results also confirmed that substituting other healthy protein sources, such as fish, poultry, nuts, and legumes was associated with a lower risk of mortality.

The study was published online in the Archives of Internal Medicine.

“Our study adds more evidence to the health risks of eating high amounts of red meat, which has been associated with type 2 diabetes, coronary heart disease, stroke, and certain cancers in other studies,” said researchers from  the Department of Nutrition at HSPH.

The research scientists from the department of nutrition and epidemiology at HSPH, and colleagues, prospectively observed 37,698 men from the “Health Professionals Follow-up Study” for up to 22 years and 83,644 women in the “Nurses’ Health Study” for up to 28 years who were free of cardiovascular disease (CVD) and cancer at base-line. Diets were assessed through questionnaires every four years.

A combined 23,926 deaths were documented in the two studies of which 5,910 were from CVD and 9,464 from cancer. Regular consumption of red meat, (Most especially processed red meat) was associated with increased mortality risk.

One daily serving of unprocessed red meat (about the size of a hamburger or small 8 oz steak) was associated with a 13% increased risk of mortality, and one daily serving of processed red meat (one hot dog or two slices of bacon) was associated with a 20% increased risk.

For cardiovascular mortality, the corresponding increases in risk were 18% and 21% while it was 10% and 16% for cancer mortality. The analytical reports took into account chronic disease risk factors such as age, body mass index, physical activity, family history of heart disease, or major cancers.

Red meat, particularly processed meats, contains ingredients that are linked to increased risk of chronic diseases, such as cardiovascular disease and cancer. These include heme iron, saturated fat, sodium, nitrites, and certain carcinogens that are formed during cooking.

Replacing one serving of total red meat with one serving of a healthy protein source was associated with a lower mortality risk: 7% for fish, 14% for poultry, 19% for nuts, 10% for legumes, 10% for low-fat dairy products, and 14% for whole grains.

The researchers estimated that 9.3% of deaths in men and 7.6% in women could have been prevented at the end of the follow-up if all the participants had consumed less than 0.5 servings per day of red meat.

“This study provides clear evidence that regular consumption of red meat, especially processed meat, contributes substantially to premature death,” said the researchers.

Substituting Other Healthy Protein Sources Including: Fish, Poultry, Nuts and Legumes Was Associated With Lower Risk of Mortality

The researchers confirmed… “On the other hand, choosing more healthful sources of protein in place of red meat can confer significant health benefits by reducing chronic disease morbidity and mortality.”

Support for the study was provided by the National Heart, Lung, and Blood Institute and the National Cancer Institute.
