In this review, authors examined the epidemiological evidence surrounding nut consumption (including peanuts) and risk of coronary heart disease.
Four studies were highlighted: the Adventist Health Study, the Iowa Women's Health Study, the Nurses' Health Study, and the Physician's Health Study. All of these epidemiological studies found consistent and remarkable evidence that nuts are cardioprotective. Results were consistent, even with a wide range of nut intake. Analysis of all the studies demonstrated a 8.3% reduction in coronary heart disease risk with each weekly serving of nuts. Additionally, the risk of coronary heart disease was 37% lower for those consuming nuts more than 4 times per week compared to those who ate nuts rarely or never.
