All natural. 0% fat. Our farmer's pledge no artificial growth hormones used (The FDA has said no significant difference has been shown and no test can now distinguish milk from rBST treated and untreated cows). Certified gluten-free. Grade A. I think it's a tragedy to mar the simple perfection of my plain Greek yogurt, but feel free to add your own drama (or granola, or fruit or honey). - Lily.
