For years, you've been told to avoid sour cream or to eat the light version. That's because 90 percent of its calories are derived from fat, at least half of which is saturated.

Sure, the percentage of fat is high, but the total amount isn't. Consider that a serving of sour cream is 2 tablespoons. That provides just 52 calories - half the amount that's in a single tablespoon of mayonnaise - and less saturated fat than you'd get from drinking a 12-ounce glass of 2 percent reduced-fat milk.

More importantly, sour cream is a close relative of butter, which means you're eating natural animal fat, not dangerous trans fat. And besides, full-fat tastes far better than the light or fat-free products, which also have added carbohydrates.
