Is Milk From Grass-Fed Cows More Heart Healthy?

Milk may be more heart healthy if it comes from dairy cows grazed on grass instead of on feedlots.

Cows on a diet of fresh grass produce milk with five times as much of an unsaturated fat called conjugated linoleic acid (CLA), which animal studies have suggested can protect your heart and aid in weight loss.

Now, according to Reuters:

“[Researchers] found, in a study of 4,000 people, that people with the highest concentrations of CLAs -- the top fifth among all participants -- had a 36 percent lower risk of heart attack compared to those with the lowest concentrations.”
