Even though they may look like decoration, alfalfa sprouts are loaded with vitamins and minerals and cost you very few calories. To avoid the risk of foodborne illnesses like salmonella and E. coli, choose cooked sprouts—they'll look less green and less crisp.
Some vegetables you should limit: Corn, artichoke hearts, beets, and sun-dried tomatoes are popular salad bar staples, but their high sugar and starch content means calories add up quickly without providing much of a nutritional benefit. For instance, sun-dried tomatoes have 139 calories per cup and beets weigh in at 58 for the same portion—compared with the 31 calories found in 1 cup of raw broccoli.
All fruit is not created equal. With no water to take up space, dried fruit packs a high caloric punch, especially if you're using a big serving spoon. Avoid large portions of dried cranberries (92 calories for 1/4 cup) and raisins (108 calories for the same size portion).
Stick with fresh fruit like berries, pears, or orange slices. These treats will sweeten your salad without too many calories (oranges have 22 calories for 1/4 cup), and their high water content will help keep you full.
A Meaty Issue: Protein
Protein is a must-have, since the nutrient keeps you satisfied and prevents cravings. Think lean: Opt for tuna, salmon, tofu, beans, chickpeas, or skinless chicken or turkey, and keep portions small. Three ounces—the size of a deck of cards or a computer mouse—is a reasonable amount. Beware anything two-toned; the extra skin means extra calories and fat.
Fat Facts: The Extras Add Up
Limit yourself to one healthy, monounsaturated fat per salad (aside from the dressing), such as nuts, seeds, olives, or avocado. Ten olives or 1/4 cup of nuts (the size of a golf ball) are surprisingly satisfying.
Cheese is high in saturated fat and sodium and is not the best source of calcium for the calories, says Lisa Young, PhD, RD, an adjunct professor of nutrition at New York University and author of The Portion Teller. If you can't lose the cheese, limit it to 1 ounce (about four dice worth) and go for lower-fat versions like goat or mozzarella instead of cheddar or blue. Or mix half low-fat with half regular cheese. "In our study, women didn't taste any difference when we combined low-fat cheese with regular," even though the calorie count was cut almost in half, says Barbara Rolls, PhD, professor of nutritional sciences at Pennsylvania State University and author of The Volumetrics Eating Plan.
Craving carbs? Crush three or four crackers or baked chips onto your salad. Don't sabotage a healthy meal with croutons. They're nutritional minefields, made with enriched wheat flour and drenched in oil.
Dress to Impress: Salad Dressings
Watch the serving size when you hit the dressing: Even honey-mustard dressing weighs in at more than 200 calories per 1/4 cup. One ladle (about 1/4 cup) of full-fat ranch or Caesar packs about 300 calories. Two ladles are the equivalent of two hot-fudge sundaes. "Ideally, you want to go for 1 tablespoon of dressing, which is what would fill half a shot glass," Dr. Young says. If you choose low-fat dressing, you can double that. A plastic takeout dressing container holds about 2 tablespoons, so fill accordingly.
Walk right past that fat-free French. A recent study found that people who ate salads with fat-free dressing absorbed fewer essential nutrients than those with fat in their salads, and that reduced-fat dressing boosted absorption of good-for-you nutrients like beta-carotene and lycopene compared with fat-free. A little fat is necessary to help your body process vitamins.
We all know that oil and vinegar is better than creamy dressing—it's lower in fat and calories, and the fat you take in from the olive oil is the heart-healthy kind—but do some maneuvering to save calories. "Typically, regular vinaigrettes, like a balsamic, are three parts oil to one part vinegar. So when trying to lose weight, do the reverse: three parts vinegar to one part oil," Newgent says.
