More good news about the health benefits of milk from grassfed cows

In recent years, researchers have discovered that some fats are very good for your health, including omega-3 fatty acids, oleic acid (found in olive oil and meat) and conjugated linoleic acid CLA. Now, attention is focusing on the health benefits of a little known fat called butyric acid (byoo' tric).

Like CLA and omega-3 fatty acids, butryric acid is a cancer fighter. Lab studies have shown that it can slow the growth of tumor cells and prompt all cells to develop more normally. According to a newly published study, feeding grain to dairy cows "reduced the contribution of butyric acid to milk fat, from 4.5 to 3.9 g/100 g milk fat, on average."

Compared with milk from cows fed grain, grassfed cows have more omega-3s, CLA, beta-carotene, vitamin E, and butyric acid.
