Meat or nuts for the heart’s desire?

Meat or nuts for the heart’s desire?


Meat protein is associated with a sharp increased risk of heart disease while nut/seeds protein is protective of the heart, reports a study conducted in the US and in France.

The study included data from more than 81,000 participants. Their diet was assessed from 2002 to 2007, and participants were followed up for a mean period of time of 9.4 years.

Researchers found that people who consumed large amount of meat protein had a 60% increase in the risk of cardiovascular disease. But people who consumed large amount of nut/seeds protein had a 40% reduction in cardiovascular disease risk.

No significant disease associations were found for proteins from grains, processed foods, legumes, and fruits/vegetables. Additional adjustments for the participants’ vegetarian dietary pattern and their nutrients intake related to cardiovascular disease risk did not change the results.

The researchers suggest that associations of cardiovascular disease with meat and with nut/seeds protein were strong, and could not be ascribed to other nutrients that are important to heart health.

They advocate that healthy diet be based on protein sources, preferring low animal meat protein intake and high plant protein intake from nut/seeds.
