Researchers in the Department of Nutritional Sciences study three areas of human developement/life cycle research:

  • Gerontology - Researchers look at strategies to communicate nutrition messages to groups and/or individuals and at the effectiveness of these strategies.
  • Maternal and Child - Researchers look at dietary intake patterns in children and adults in America and beyond. From these patterns, assessments are made about relationships between diet and health.


Studies review the nutritional status and health outcomes of rural older adults.

In the longitudinal Geisinger Rural Aging Study, many participants are overweight or obese. At the same time, many also have dietary intakes that do not provide adequate vitamins and minerals. This low intake of vitamins and minerals leads to low levels of blood nutrients, which has also been shown to lead to more medical problems.
