Which Is Worse: When the Real Things Trump Diet Food

Most people consider yogurt to be a tasty way to put a big dent in their daily 1,000–1,200 mg calcium requirement. However, the artificial sweeteners and fillers in the "light" fat-free flavored varieties displace calcium, says Jibrin, sometimes by as much as half (per 6-ounce container,150 mg vs. 300 mg for the fat-free plain stuff). To get all the bone-strengthening benefits of the plain (yet admittedly bland) version, Jibrin suggests eating the low-fat or nonfat unflavored version and sweetening it with a half a teaspoon of honey—or, better, mixing it with real fruit.
