March is National Nutrition Month. The Area Agency on Aging and Disability from the Upper Cumberland Development District is in the process of holding a canned food drive to support the aging population in Warren County.The nearly month-long drive started last year after the organization was made aware of a strong need by senior citizens in Warren County for food.Fran Davis, a family caregiver with the agency, says the canned food drive fills a need in the area. “Tennessee ranks second in the nation for senior hunger,” Davis said.
