The American Heart Association and Aramark are launching a new community engagement program in three key cities -- Philadelphia, Chicago and Houston -- as part of their Healthy for Life® 20 By 20 initiative to improve the diet and health of millions of Americans by 20 percent by the year 2020. The pilot program, taking place throughout the spring, will track and measure the impact of attitudes and behaviors of primarily single mothers or single heads of households responsible for food and meal decisions for their families.
