Ethos, a Jamaica Plain-based nonprofit, was recently chosen to be in charge of the Boston Elder Nutrition Program, which is responsible for providing more than 2.1 million meals to Boston senior citizens per year. The meals are subsidized by the federal, state and city governments with the goal of providing healthy and nutritious meals through Meals on Wheels to homebound senior citizens to help them stay living independently, and meals in neighborhood settings called Community Cafes. The Boston Elder Nutrition Program is being made possible through a collaboration between Boston’s Age Strong Commission (formerly the Commission on Affairs of the Elderly), and the elder services non-profits Central Boston Elder Services, Boston Senior Home Care and Ethos, which all working together to bring healthy food to seniors. Meals on Wheels of America, the advocacy group representing elder nutrition providers, reports that seniors make up 22 percent of the state’s population, with more than 27 percent living alone and 12 percent threatened by hunger, according to a press release. “For millions of Americans, Meals on Wheels and Community Café programs are literally the difference between remaining in their own homes and needing to relocate to a nursing facility,” said Dale Mitchell, CEO, Ethos, via press release.
