Navigating ultra-processed foods

How can you tell whether a food is ultra-processed? What is the difference between "processed food" and "ultra-processed food?" Kristina Petersen, associate professor of nutritional sciences, explains in a recent Q&A.

Nutritional Sciences at Penn State examines how humans gain energy from food and how nutrition choices affect our health over time.
Solidly rooted in chemistry, biology, physiology, psychology, neuroscience, behavior, and development, our body of work covers the effects of nutrition at all levels, from the molecule to the organism, to the population at large. Our programs aim to nurture a new generation of leaders in bench and behavioral sciences who will push the limits of our understanding of nutrition as it relates to human health.
