• Milk: Low-fat and nonfat dry milk are the best buys. Regular (fluid) low fat or nonfat milk are still a thrifty choice, according to the EWG, but not a “best buy.”
• Cheese: Cottage cheese, queso fresco and ricotta are the best buys in the cheese department.
• Yogurt: Nonfat plain yogurt is the only option in this category. The EWG recommends sweetening it with fresh fruit (so do I).
