School lunches are a significant component of the educational process for most children. For some children, lunchtime is the only time of day that they receive a balanced and nutritious meal. Lunch in most schools is offered through a mix of federal subsidies and revenue from the sale of meals to students. The nutritional quality and healthiness of school lunches can differ substantially from district to district. In the past few years, there has been increased momentum to make school meals healthier, in reaction to the rising problem of childhood obesity and other health concerns. Lunch in Schools have attempted to minimize the quantity of processed foods and added sugars on their menus, and to add more fruit, vegetables, and whole grains.
