The aging of the American population and subsequent increase in chronic disease will have a profound effect on public health, social services and healthcare. In the United States, a healthy lifestyle, diet and exercise can help delay and/or treat chronic diseases and promote quality of life. Former studies have evaluated home food inventories in U.S households for several nutrients, yet data regarding in-home pantries of homebound older adults is scarce. Quality dietary intake is important when energy requirements are reduced due to aging; seniors may be at nutritional risk from vitamin and mineral inadequacies, contributing to a decline in health status and function. The in-home food inventory takes on major importance for the homebound due to physical, mental, economic and social limitations impacting food procurement, storage, preparation and consumption. The current study details the nutritional adequacy of the in-home food inventory of homebound seniors and examines gender and ethnic differences. Highest values for days meeting Daily Values and Dietary Reference Intakes were found for vitamin A and sodium. Convenience foods were abundant, providing economical, shelf-stable, and easy to prepare meals when functionally limited. Vitamin D and calcium were found to be the limiting nutrients in this study. The highest frequency of significant differences in home food inventories was found between races: White compared to non-White, and for females: White compared to non-White. Dairy products have repeatedly been reported as the major contributor of vitamin D for adults. In this study, the contribution of dairy products to total vitamin D ranged from 16.7% (non-White males) to 32.2% (White females); females had 51% more dairy products in their inventories than males. Fish and ready-to eat cereals took on major importance in food inventories, providing nutrient dense, shelf-stable and economical sources of vitamin D. Reduced consumption of milk and major sources of vitamin D, along with declining cutaneous synthesis of vitamin D with age present challenges in developing public health strategies to achieve adequate vitamin D intake in the older population.
