Diet secrets: share one, pass one

Ok, so if you haven't heard of this drink, you're missing out: Kombucha. It's a fermented tea that tastes something like a gingerale. There's no caffeine, though. It's also a probiotic, which makes it a good beverage for those of us with sensitive tummies, IBS, and all that other annoying GI stuff. Even better, it has only 70 calories in the full bottle of 16oz. Drink it on an empty stomach, and it kills your appetite a bit, too. I like the Grape, Trinity, and Gingerade flavors but there are a bunch more, mango, greens...One downside: it cost almost $5 at some health food stores/delis. Whole Foods, though, occasionally puts it on sale, selling two for $5.
