December 7, 2017 — Eating several small servings of nuts each week may significantly lower your risk of heart attack or stroke, according to a new study from Harvard T.H. Chan School of Public Health. In this week’s episode we speak with Marta Guasch, a research fellow in the Department of Nutrition, and author of the study—which is one of the largest to date on the health benefits of nuts. We’ll discuss what differentiates this study from other research on nuts, how many you should be consuming each week, and simple ways to include more nuts in your diet.

Later in the episode, we’ll tell you about research examining the effectiveness of strategies to increase physical activity on a large scale.
