Many low-income families, especially those living in urban and rural "food deserts," lack access to affordable, nutritious foods. As a result, about 40% of households with incomes below the poverty line experience food insecurity. Food insecurity is associated with poor health and developmental outcomes for children. Effective strategies to improve nutrition for low-income families include increasing enrollment in programs like WIC and SNAP, ensuring access to healthy foods through transportation and farmers' markets, and providing nutrition education.
