15. Low-fat Milk, $0.25 cents per cup, about $4 per gallon : Got milk? One calcium-filled glass can help keep teeth strong and even help keep off those excess pounds. Add a splash to a fruit smoothie, or enjoy in a bowl of oats or cereal.
16. Low-fat Yogurt, about $1 per 6 oz cup : Skip the bagel and pick up a quick treat that’s filled with protein and calcium! Enjoy for breakfast with some granola, or as a post-workout snack. Just beware of flavors loaded with extra sugar. Extra points for choosing superfood Greek yogurt — though it can be more expensive, so waiting for it to go on sale is a smart move!
17. Low-fat Cottage cheese, $0.88 per 1/2 cup serving, about $3.50 per 16 oz container: It’s time to put looks aside. This clumpy, mild cheese is surprisingly high in protein, and tastes great in both sweet and savory dishes. Top with sliced pineapple and berries for a sweet protein-packed treat, or make it savory in a low-fat creamy pasta sauce.
