Meals on Wheels is a program that delivers meals to individuals at home who are unable to purchase or prepare their own meals. The name is often used generically to refer to home-delivered meals programs, not all of which are actually named "Meals on Wheels". Because they are housebound, many of the recipients are the elderly, and many of the volunteers are also elderly but able-bodied and able to drive automobiles. Research shows that home-delivered meal programs significantly improve diet quality, increase nutrient intakes, reduce food insecurity and improve quality-of-life among the recipients. The programs also reduce government expenditures by reducing the need of recipients to use hospitals, nursing homes or other expensive community-based services.
