If you've shopped for yogurt lately, you might have noticed a new adjective on some containers. Dairy producers large and small have pounced on the term grass-fed.
But what does it mean? That's not so clear, reports Civil Eats. You might imagine that grass-fed dairy products originate with milk made from cows who eat only grass and hay, but the term (like others including "humane" and "natural") is not regulated by the government. "One company may define 'grassfed' as a diet that includes as much as 15 percent grain," writes Lisa Elaine Held, "and and a consumer would have no way of knowing the difference."
The USDA (which just rescinded its guidelines for grass-fed meat) has displayed no interest in getting involved, but third-parties are stepping in. The American Grassfed Association is set to unveil a grass-fed dairy certification standard. Since 2013, Pennsylvania Certified Organic has offered a similar certification. Its stamp of approval appears on Stonyfield Farm's newest yogurt line.
