Al-Shaar et al. found that greater intakes of total, unprocessed, and processed red meat were each associated with a higher risk of coronary heart disease. Compared with total, unprocessed, or processed red meat, other dietary components such as soy, nuts, and legumes were associated with a lower risk of coronary heart disease. These associations were stronger among older men. These findings are consistent with the effects of these foods on low density lipoprotein cholesterol levels and support a health benefit of limiting red meat consumption and replacement with plant protein sources; this would also have important environmental benefits. The team also found that substituting whole grains or dairy products for total red meat and substituting eggs for processed red meat were also associated with a lower coronary heart disease risk.
