Meat protein is unhealthy, but protein from nuts, seeds good

A study conducted by researchers in California and France has found that meat protein is associated with a sharp increased risk of heart disease while protein from nuts and seeds is beneficial for the human heart.

Titled "Patterns of plant and animal protein intake are strongly associated with cardiovascular mortality: The Adventist Health Study-2 cohort," the study was a joint project of researchers from Loma Linda University School of Public Health in California and AgroParisTech and the Institut National de la Recherche Agronomique in Paris, France.

The study, which was published online today by the International Journal of Epidemiology, found that people who consumed large amounts of meat protein experienced a 60-percent increase in cardiovascular disease (CVD), while people who consumed large amounts of protein from nuts and seeds experienced a 40-percent reduction in CVD.

The study, which included data from more than 81,000 participants, is one of the few times detailed sources of animal protein have been examined jointly with animal fat in a major investigation.

Gary Fraser from AgroParisTech and the Institut National de la Recherche Agronomique, served as co-principal investigators.

"While dietary fats are part of the story in affecting risk of cardiovascular disease, proteins may also have important and largely overlooked independent effects on risk," Fraser said. He added that he and his colleagues have long suspected that including nuts and seeds in the diet protects against heart and vascular disease, while red meats increase risk.

Fraser added that nutritionists have traditionally looked toward what he termed "bad fats" in meats and "helpful fats" in nuts and seeds as causal agents.

However, these new findings suggest more. "This new evidence suggests that the full picture probably also involves the biological effects of proteins in these foods," he said.
