FAQ of the day:
Is cheese a good source of protein?
Cheese is a good source of protein, but so what? Most Americans get more than enough protein. A much larger problem is that we get too much saturated fat, which raises blood cholesterol and contributes to heart disease, the nation's No. 1 killer. A grilled cheese sandwich made with 1 1/2 oz. of cheddar cheese provides 10 grams of protein (about 20% of a 150-lb. person's daily needs) but also 9 grams of saturated fat (about 40% of the upper limit for a person who consumes 2,000 calories a day). Low-fat and fat-free dairy is a better bet.
