Think these 8 foods are healthy? Wrong!

'Calorie-free' spray margarine
Even though some spray margarines claim to be "calorie-free," labeling laws allow products with fewer than 5 calories per serving to claim to have zero calories. So, while one spritz may be inconsequential, the whole bottle could have as much as 900 calories.

Smarter sub: Spray-it-yourself olive oil. In this case, a bit of real fat is more healthful and flavorful — and within a reasonable calorie range if you watch your portions. Investing in an olive oil mister ensures you don't put on too much.

Health bonus: Decreased inflammation throughout the body, which helps your heart and lowers cancer risk, thanks to monounsaturated fatty acids.

Try: Misto olive oil sprayer. Find one at any kitchen store for around $10.


Nonfat salad dressing
Fat-free salad dressings are often packed with sugar — so your dressing may be loaded with calories. Ironically, a salad without fat is not living up to its potential. "You need a little fat to absorb vitamins A, D, E, and K and other nutrients," says Katherine Tallmadge, RD, spokesperson for the American Dietetic Association.

Smarter sub: Oil-based salad dressings. You'll get good-for-you fats instead of the saturated fat found in some creamy dressings. Look for ingredients like olive oil, vinegar, and herbs.

Health bonus: Vision protection. As many as five times more carotenoids — antioxidants that are essential for eye-sight — are absorbed when salads are consumed with fat rather than with no fat.

Try: Newman's Own Olive Oil & Vinegar Dressing. Two tablespoons have 150 calories, 2.5 g sat fat, 0 g fiber.


Low-fat cookies
Do you remember the SnackWell's craze? Low-fat cookies are still popular, and many dieters think they can indulge guilt free. The problem is that most of these snacks are made with extra sugar, which means they often have just as many calories as the full-fat version, if not more.

Smarter sub: Oatmeal cookies. These are a great way to indulge a cookie craving while also getting whole grains. Not all are created equal, though: Skip those made with high fructose corn syrup, white flour, and butter in favor of varieties made with honey or cane juice, whole wheat flour, and oil.

Health bonus: Lower cholesterol. The fiber found in oatmeal keeps your body from absorbing bad cholesterol.

Try: Kashi TLC Cookies. One cookie has 130 calories, 1.5 g sat fat, 4 g fiber.


100-calorie snack packs
You might want to skip these if you're trying to lose weight. A recent study showed that people may eat more food and calories if the portions are presented in small sizes and packages. With smaller serving sizes, study participants didn't feel the need to regulate their intake, so they ate more than one portion before feeling satisfied.

Smarter sub: A small serving of almonds. Their healthy monounsaturated fat, fiber, and protein will tide you over until your next meal.

Health bonus: Stronger bones. Almonds are an excellent source of bone-building magnesium, as well as the immune-boosting antioxidant vitamin E.

Try: Blue Diamond Natural Oven Roasted Almonds. A 1 oz serving has 160 calories, 1 g sat fat, 3 g fiber.
