A growing number of younger U.S. adults are being hospitalized for strokes, and a new study suggests that’s at least in part because more of them have risk factors like high blood pressure, obesity and diabetes.

A new study from Tufts University found diet to be the cause behind half of all heart disease, stroke and diabetes deaths. Researchers warn that these dietary habits not only influence many of the risk factors for health, but also pose substantial health and economic burdens.
