Researchers found that people with slightly elevated blood pressure, or pre-hypertension, were 66 percent more likely to have a stroke than those with normal blood pressure.
The results stayed the same even after investigators adjusted for other stroke risk factors like diabetes and smoking.
The CDC says nearly a third of American adults have the condition.
And a new study in the Journal of Public Health says if concession stands offer healthy foods, they will sell.
University of Iowa researchers went to a local school district's concession stand.
They added healthy foods like apples and string cheese to the menu and used healthier ingredients in classics like nachos and popcorn.
The result: sales remained stable, and profits even went up a bit.
The classics still sell well, but the school says consumers respond well to having a choice.
