Concerns about senior citizens living in poverty in the 1960s led to the establishment of the Elderly Nutrition Program (ENP) in 1972. This federally funded program provides grants to state and area agencies on aging to help finance the cost of congregate and home-delivered meals for older adults living independently in the community. The program is periodically re-authorized under the Older Americans Act and is administered by the U.S. Department of Health and Human Service's Administration on Aging. The primary activity funded under Title III is the preparation and serving of nutritious meals for adults over the age of 60 and their spouses. Title III-A provides funding for tribal organizations to provide similar meal services. The meals are distributed through two mechanisms: (1) delivered to the homes of seniors who are not mobile or have self-care challenges, and (2) served at a group meeting place such as a senior center, church, community hall or public school. Homebound seniors receive one meal per day (several fresh and frozen meals may be included in a single delivery), and communities that offer congregate meals are encouraged to offer a meal at least five times per week. Meals must meet Dietary Reference Intakes and USDA Dietary Guidelines for older adults. In 2011, the budget for Title III programs was $817.8 million and an estimated 2.6 million people were served. Grants are made by the Administration on Aging to state agencies and local area councils on aging that provide a variety of other services to their communities' seniors. The program relies heavily on volunteers; a savings of about 10% per meal is attributed to volunteer labor. Over the last 20 years, more funds were shifted from congregate meal support to home-delivered foods, often referred to as Meals on Wheels. While the aim of ENP is to target low-income elderly in cities as well as rural settings, there is no means test to use these services; drafters of the initial legislation wanted to limit barriers to use of the program by older adults.
