This study examined the relationship of diet with heart disease. The study included 337 healthy middle-aged men who were followed for up to 20 years.

Regarding the consumption of animal based foods, the study found:
(a) Men who consumed the most animal fat had a 23% decreased risk of heart disease compared to the men who consumed the least animal fat.
(b) Men who consumed the most animal protein had a 15% decreased risk of heart disease compared to the men who consumed the least animal protein.

The data from the study reveals that men who consume higher quantities of foods of animal origin have lower rates of heart disease.
