After analyzing the results, they found that those who consumed large amounts of meat protein were 60 percent more likely to develop heart disease. On the other hand, people who ate large amounts of protein from nuts and seeds had a 40 percent reduced chance of getting the illness.
"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," lead author Gary Fraser said in a statement. "This new evidence suggests that the full picture probably also involves the biological effects of proteins in these foods ... This research is suggesting there is more heterogeneity than just the binary categorization of plant protein or animal protein."
