Slideshow Pictures: Healthy Eating -- Best and Worst Appetizers

WORST: Onion Blossom

It may be your waistline that blossoms if you're a fan of fried onions. "It's good to start off with a vegetable," says Joan Salge Blake, RD, a spokeswoman for the American Dietetic Association. "But once you fry it, you're frying in calories." The onion blossom at one popular restaurant has 1,552 calories, 83 g of fat, and 5,508 mg of sodium - more than double the daily sodium limit for healthy adults.

BEST: Vegetable Kabobs

Grilled vegetable kabobs offer a nutritious, low-calorie alternative to fried onions. If this isn't on the menu, ask for a side of grilled vegetables as your appetizer. Veggie kabobs are also easy to make – try skewering onions, red and green bell peppers, mushrooms, tomatoes, and zucchini. Brush with a lower-fat garlic and herb marinade. Two large kabobs will have about 80 calories.

WORST: Spinach Artichoke Dip

Don't let the word "spinach" fool you. Traditional spinach artichoke dip is not a healthy starter. A typical order contains about 1,500 calories, 100 g of fat, and 2,500 mg of sodium. The trouble is the cream base, which is loaded with saturated fat. If you make this dip at home, try using a base of nonfat Greek yogurt instead.

BEST: Spinach Salad

The best appetizers are low in calories, but satisfying enough to curb how much you eat during the rest of your meal. Salads made with spinach or other leafy greens do this very well. Studies suggest you'll eat about 10% less during a meal if you start off with salad. A cup of fresh spinach with a tablespoon of vinaigrette has just 150 calories.

WORST: Cheese Fries

The worst appetizers can "take over the meal," Blake warns. "Some of them have more calories than the main entrée." One offender is cheese fries – French fries with melted cheese on top. Variations may include bacon bits or ranch dressing. A full order packs up to 2,100 calories, 150 g of fat, and a whole day's worth of sodium (2,300 mg).

BEST: Crab Cakes

Blake recommends using appetizers to work in healthy foods you might be eating too little of. Seared crab cakes offer an appealing way to get more seafood into your diet. Served with chili sauce, a typical crab cake has about 300 calories, 16 g of fat, and 800 mg sodium.

WORST: Cheeseburger Sliders

Don't be fooled by their size – "sliders" pack a lot of calories into a tiny sandwich. A typical restaurant order includes three mini-burgers with cheese and sauce, totaling 1,270 calories, 81 g of fat, and 2,270 mg of sodium.

BEST: Beef Skewers

When you're craving a meaty appetizer, opt for beef skewers. In Asian restaurants, this may be listed as beef satay – skewers of beef with peanut sauce. At home, you can grill skewers of lean beef with onions, garlic, hoisin, soy, and barbecue sauce. A quarter-pound serving has about 130 calories, 5 g of fat, and 803 mg sodium.

WORST: Loaded Potato Skins

Potato skins filled with melted cheese, meats, and sour cream are as fattening as they are tempting. "You're taking a potato and adding saturated fats," Blake cautions. At 150 calories a pop, the trick to enjoying these is to have just one. Devour a whole plateful and you'll take in about 1,000 calories, 100 g of fat, and 1,900 mg of sodium.

BEST: Stuffed Mushrooms

Stuffing mushrooms instead of potato skins helps keep the portion size down. Mushroom caps filled with cheese and breadcrumbs have less than 50 calories each. That means you can eat half a dozen and still keep your appetizer under 300 calories, along with 19 grams of fat, and 720 mg of sodium.

WORST: Fried Calamari

Like many forms of seafood, squid can be nutritious. But when you bread it and fry it in oil, you're drenching it with calories and fat. A typical restaurant portion contains about 900 calories, 54 g of fat, and 2,300 mg of sodium – not including any sauce.

BEST: Shrimp Cocktail

Shrimp cocktail is very low in saturated fat and calories. It's also a refreshing source of omega-3 fatty acids, which promote healthy circulation. To keep the calorie count low, stick to tomato-based sauce. A serving of shrimp with cocktail sauce has about 120 calories.

WORST: New England Clam Chowder

Clam chowder sounds like it should be healthy, especially as a way to take in some extra seafood. Unfortunately, the New England variety is made with a fattening cream base. A 12-ounce bowl contains about 450 calories, 34 g of fat, and 1,190 mg of sodium.

BEST: Vegetable Soup

Like salad, having a bowl of soup can curb how much you eat during the rest of the meal. The key is choosing a low-calorie option, such as a tomato-based vegetable soup. A 12-ounce bowl has about 160 calories, 3.5 grams of fat, and 1,240 mg sodium. Stay away from cream-based vegetable soups, which are higher in calories and saturated fats. When buying canned soup, look for those marked "low in sodium."

WORST: Chicken Wings

A typical appetizer portion of buffalo chicken wings has more than 700 calories and 40 g of fat. Ranch sauce adds another 200 calories and 20 g of fat. That's 900 calories and 60 g of fat – not to mention more than 2,000 mg of sodium – before you even get to your main meal.

BEST: Lettuce Wraps

If you're craving spicy chicken, skip the wings and try lettuce wraps. You can make these at home by wrapping diced spicy chicken and vegetables in a lettuce leaf. Each wrap has 160 calories and 7 g of fat. If you order this appetizer at a restaurant, be sure to share. A plate of four wraps has a total of 640 calories, 28 g of fat, and 650 mg sodium.

WORST: Mozzarella Sticks

There's something about a stick of warm, gooey cheese that is irresistible – until you take a look at the nutritional facts. A typical order has 940 calories, 46 g of fat, and 2,830 mg of sodium. That puts mozzarella sticks pretty much on par with chicken wings.

BEST: Edamame

Go out on a limb and try something entirely different. These green pods, known as edamame, are a popular appetizer in Asian restaurants. It's fun to open the pods and pop the young soybeans into your mouth. One serving has 122 calories, and 5 g of fat.

WORST: Chili Cheese Nachos

They may be a festive way to start an evening out, but nachos and cheese dip are among the least healthy appetizer choices. Eat an entire order yourself, and you'll take in 1,680 calories, 108 g of fat, and 4,280 mg of sodium – nearly twice the recommended daily limit for sodium.

BEST: Sliced Peppers with Salsa

For a homemade alternative to chips and dip, try sliced peppers with salsa. Cut up red and green bell peppers and use them as tortilla chips for dipping in salsa. This is a fun way to sneak more vegetables into your diet. You can dip a whole pepper's worth of "chips" and stay under 50 calories.
