Bye-bye protein bars, hello salmon? Eating foods high in healthy fats (like cold-water fish) may help athletes avoid stress fractures and tendonitis, found a study at the State University of New York, Buffalo. Runners there who ate a lowfat diet were more than twice as likely to suffer a trainingrelated injury. “Skimping on fat lowers your intake of omega-3 fatty acids and calories,” says Kristen Gerlach, Ph.D., the study’s lead author. “Both of these factors make it tougher for your body to repair tissue after workouts, so you’re more susceptible to injury.” Get 30 percent of your daily calories from healthy fats and you’ll stay off the sidelines.
