Research studies show clear nutritional advantages from beef, milk, and milk-derived foods (such as cheese and yogurt) obtained from100% grass-fed cows. These advantages typically include better fat quality (often involving more omega-3 fats, better ratios of omega-6 to omega-3 fats, increased amounts of conjugated linoleic acid, and higher quality saturated fat); increased amounts of certain vitamins (for example, vitamin E, or vitamin A in the form of beta-carotene); and increased amounts of other nutrients.
