Another issue facing schools is the prevalence of other sources of food and snacks, which often make the problem of school lunch nutrition worse. One such source is called “commodity foods” which are free or low cost foods subsidized by the USDA. Of the subsidy money, 73% goes to buy meat and dairy, whereas less than 1% goes to subsidize fruits and vegetables. Schools also may receive “bonus foods,” which are free surplus foods from farms or large-scale agriculture, which also are not typically healthy options for children. Most concerning is the widespread use of “competitive foods,” a term describing foods and snacks offered outside of the auspices of the NSLP. Competitive food includes such items as vending machines (which usually contain high-calorie sugary drinks and sodas, as well as other junk foods), snack bars, and pizza or bake sales.
