Cola-typ
e soft drinks can damage your kidneys.
Despite their global popularity, there's nothing remotely healthy about cola beverages: Drinking 16 ounces or more daily (whether diet or regular) doubles your risk of chronic kidney disease, according to a recent NIH study of more than 900 people. The researchers already knew that consuming any type of soft drink—the average American adult guzzles 59 gallons' worth per year—is associated with several risk factors for kidney disease (hypertension, diabetes, and kidney stones), but the spike in the cola category was remarkable. Experts suspect that the ingredient phosphoric acid may be the culprit; it's been repeatedly linked to "urinary changes that promote kidney stones," say the study authors. Cola has an additional knock against it: Consumption is associated with significantly lower bone density in women, increasing the risk of osteoporosis and bone fractures, says a separate study.
Bottom Line: If you're going to indulge in an occasional soda, go for Sprite, 7-Up, ginger ale, and the like—the NIH study found that noncola drinks didn't have the same impact on the kidneys. But you'll be better off if you skip soda altogether, even the sugar-free varieties: Recent research showed an association between drinking diet soda and weight gain.
Cracking your knuckles can cause arthritis
If you're suffering from osteoarthritis in your hands, it certainly has nothing to do with this nervous tic. One study at the former Mount Carmel Mercy Hospital in Detroit compared 74 people (age 45 and older) who had been chronic knuckle crackers for decades with 226 who always left their hands alone; researchers found no difference in the incidence of osteoarthritis between the two groups. But there are reasons to stop this annoying habit: The same study found knuckle crackers to be far more likely to have weaker grip strength and greater hand swelling, both of which can limit dexterity. As for osteoarthritis, that's more likely due to genetics and increasing age.
Bottom Line: Try turning your nervous energy into a less harmful habit that occupies your hands (such as doodling). If a different activity doesn't get you to stop, try putting a large rubber band around your wrist and every time you catch yourself cracking your knuckles, pull it back and let it snap as a reminder that your habit really can be harmful. Most important, get to the bottom of what's causing your nervousness in the first place—you may crack your knuckles more often at work than at home, for example—and address those sources directly.
