In Praise of Avocados

If you like avocados but avoid them because they're "fattening," take heart. Avocados' fat isn't the artery-clogging kind. Put 2-3 thin slices on salads and sandwiches to add flavor, and give your heart a healthy dose of monounsaturated fat and vitamin E. Just remember, even "good fat" has lots of calories, so if you are watching your waistline, limit your portion to only a couple of thin avocado slices with your meal.
