Levels of CLA, a fatty acid found only in the meat and milk of ruminants such as cattle, are higher in animals fed on lush pastures, but that's not what most cows eat. Rather, they are fed mostly grains. A 1999 study, published in the Journal of Dairy Science, found that milk from grass-fed cows contained up to 500 percent more CLA than milk from cows fed a diet of 50 percent grain.
