Going Greek.

Stonyfield Farm is shaking up the dairy case with its Oikos Organic 0% Fat Greek Yogurt.

For centuries, the Greeks have strained their yogurt to remove extra liquid (whey). That gives each 6-ounce cup of Greek yogurt roughly twice as much protein (16 grams) as ordinary yogurt.

Since a little calcium gets tossed out with the whey, plain Greek yogurt has slightly less (20 percent of a day's worth) than plain ordinary yogurt (30 percent).

But the key difference is taste. Greek yogurt is tangy and much more creamy. One spoonful and you'll check the label to see if it's really fat-free (yup), and if it really has just 100 calories (if it's plain, it does).

What's more, Oikos Vanilla has fewer calories (120) than, say, Dannon All Natural Vanilla (150), in part because it's got less added sugar.

Want yogurt that's even thicker and richer tasting? Try Fage Total 0% Greek Strained Yogurt. You could use it instead of real sour cream and no one would know. (Fage is avail able at Trader Joe's, Whole Foods, and a raft of regional supermarket chains. Just be careful not to grab Fage's fattier Total, Total Light, or Total 2% Greek Yogurt by mistake.)

Top any fat-free Greek yogurt with a handful of berries and dig in. Or eat it by the spoonful, right out of the tub.

It's food fit for the gods.
