Red Meat And High-Fat Dairy May Increase Heart Disease Risk

Where do you get your protein? If it's from red meat (steak and pork), processed meat (bacon and salami), and high-fat dairy foods, it may be increasing your risk of fatal and non-fatal heart attack.

That was the finding of a recent assessment of the very large Nurses' Health Study which followed over 84,000 women for 26 years.¹

It found:

• Higher intakes of red meat, red meat excluding processed meat, and high-fat dairy were significantly associated with elevated risk of coronary heart disease (CHD).
  
  
• Higher intakes of poultry, fish, and nuts were significantly associated with lower risk.

And concluded:

"These data suggest that high red meat intake increases risk of CHD."

The study was unique in that it investigated how substituting one source of protein for another, e.g. nuts, fish, or poultry for red meat, affects heart disease risk. It found, for example, that substituting one serving of nuts for one serving of red meat reduced CHD risk by 30%; substituting a serving of fish for red meat reduced it by 24%.

Although the study was conducted on women, the researchers say men are likely to benefit from the findings as well.

Lead author of the study, Adam Bernstein:

"Our research adds to the growing and convincing body of evidence that red meat intake should be minimized or excluded from the diet in order to maintain cardiovascular health."
