The Consortium to Lower Obesity in Chicago Children has introduces a new program called 5-4-3-2-1 where 24 high school students teach nutrition classes to elementary age children. The classes are being held at various after-school programs and day care centers. The students are teaching students the 5-4-3-2-1 principle, which advocates five servings of fruits and vegetables, four glasses of water, three servings of low-fat dairy products, two hours or less of screen time and one hour or more of exercise daily.
