Could eating tomatoes help prevent strokes? A Finnish study suggests that high blood levels of lycopene, unlike those of other antioxidants, could be associated with a significantly reduced risk of stroke. Vegetables, especially tomatoes, are a significant source of lycopene. The analysis in the journal Neurology followed 1,031 men ages 46 to 55, measuring their blood levels of five antioxidants and recording incidents of stroke. Men with the highest lycopene levels were 55 percent less likely to have a stroke than those with the lowest. There was no association between stroke and blood levels of the other four antioxidants -- alpha carotene, beta carotene, alpha tocopherol and retinol. Lead author Jouni Karppi, a researcher at the University of Eastern Finland, said, "The consumption of vegetables is good for your health anyway, in addition to whatever protection it offers against stroke."

Management consultants say 60 percent of senior execs experience high stress on a regular basis, and a thriving industry of motivational speakers teaches business leaders how to manage their corrosive burden of stress. But just how uneasy lies the head that wears the crown? Not very, it turns out. A new study reveals that those who sit atop the nation's political, military, business and nonprofit organizations are actually pretty chill. Compared with people of similar age, gender and ethnicity who haven't made it to the top, leaders pronounced themselves less stressed and anxious. And their levels of cortisol, a hormone that circulates at high levels in the chronically stressed, told the same story. The source of the leaders' relative serenity was pretty simple: control. "Leaders possess a particular psychological resource -- a sense of control -- that may buffer against stress," the Harvard University research team reported in Proceedings of the National Academies of Sciences.
