Which Yogurts Are Healthiest?

If you're looking for a healthy snack, you may turn to yogurt.

But which yogurts are the healthiest? There are so many on supermarket shelves, it's hard to know which is best for you.

But, on "The Early Show", Erin Hobday, senior diet and nutrition editor of Self magazine, had the scoop on the top seven brands.

She warns that yogurt can easily go from being a super snack to a "sugar bomb." On its own, it has about 12 grams per serving of natural milk sugar, which isn't too sweet. But many brands add sugar to make it sweeter.

Hobday says Self "absolutely" considers yogurt a super-food for weight loss, noting that people on a low-cal diet that included fat-free yogurt lost 81 percent more fat than people on a similar plan that didn't include yogurt. The balance of carbs and protein in yogurt can keep blood sugar levels steady and stave off hunger, while the calcium it contains may help your body store less fat.

YOGURTS FROM LOWEST SUGAR CONTENT TO HIGHEST (SIX-TO-SIX-AND-A-HALF OUNCE SERVINGS)

Fage Total 0% Plain Greek Yogurt: 90 calories, 7 grams sugar

Greek yogurt is increasingly popular because its really creamy and high in protein-it has nearly twice as much protein as other plain yogurts. But there's a catch: it has less calcium than other cups. It's processed in a different way so it loses calcium. Alternate between Greek-style and conventional yogurt (like the Dannon, below) to get all of the benefits that yogurt has to offer.

Dannon All Natural Nonfat Plain Yogurt: 80 calories, 12 grams sugar

Six ounces of unflavored yogurt (like this one) should have 30 percent of your daily calcium needs-look for that on the label. And remember to stir it up! The watery layer that sometimes settles on top of your carton of plain yogurt is good for you. It's whey protein, which contains muscle-building amino acids. Mix it in; don't skim it off.

Ronnybrook Peach Creamline Yogurt: 130 calories, 17 grams sugar

Fruity yogurts, like this one, tend to contain less calcium than plain (some of the calcium-rich yogurt is replaced by fruit). Check the label and look for those that have 19 percent of your daily calcium needs per cup. It does have added sugar, but it's on the low end of sugar content. This is good if you don't like plain yogurt but want a little sugar.

Stonyfield Farm Fat Free French Vanilla Yogurt: 130 calories, 24 grams sugar

If you're looking to lose weight, look for flavored yogurts, like this one (and Ronnybrook above) that have 130 calories or less. And avoid low-fat types with more than 1 gram of saturated fat.

Yoplait Original Blueberry Yogurt: 170 calories, 27 grams sugar

It's kind of cool for two reasons. It has probiotics, the healthy bacteria in yogurt, have been linked to strong immune systems and a lower risk for gum disease and even some cancers. Yoplait's yogurts are also fortified with vitamin D, which helps your body absorb more calcium. But not all yogurts have enough of the good stuff. The National Yogurt Associations Live & Active Cultures seal appears on some cartons that do (such as this one). It does have more sugar than we'd like.

Breyer's YoCrunch Vanilla Yogurt with M&M's: 200 calories, 30 grams sugar
AND Stonyfield Farm Fat Free Chocolate Underground Yogurt: 180 calories, 35 gram sugar

This is like a dessert with some nutritional benefits. Six ounces of most plain yogurts have about 12 g of natural milk sugar (or lactose). That's okay, even if you're dieting. But every 4 g on top of that is a teaspoon of added sugar yours has 25 grams or more (like these two sweet treats) consider it dessert!
