In 2006, the city set out to eliminate whole milk from cafeteria lunch menus and took the further step of banning low-fat flavored milks, allowing only skim milk (white and chocolate). The New York City school system purchases more milk than any other in the United States. Although the dairy industry aggressively lobbied against the new plan they ultimately failed to prevent its implementation. In October 2009, the DOE banned bake sales, though some schools continued to have them. The DOE cited the high sugar content of baked sale goods and that 40% of city students are obese. However, vending machines in the schools operated by Frito Lay and Snapple continued to sell high processed empty calorie foods such as Doritos and juices. As part of the DOE's program to create healthy diets among students, Frito Lay was obligated to put Reduced Fat Doritos in machines. The DOE considers Reduced Fat Doritos a healthy snack based on its June 2009 request for healthy snack vending machine proposals. However, the school lunch menu still contained numerous highly processed foods and high sugar content foods including chicken nuggets, French fries, French toast and syrup. This menu also continued to fail to meet the mandatory physical education requirements of the state. The New York State Assembly published a report that the NYCDOE failed to maintain or improve playgrounds, instead turning them into ad-hoc additional classroom space or parking lots. In January 2011, the DOE began a pilot program called Connecting Adolescents to Comprehensive Health (CATCH) that offers some reproductive health services to students in grades 9–12. Services include providing access to birth control such as condoms, emergency contraceptives, and birth control pills. Starting with 13 high schools, it has grown to serve 90 high schools by 2022. New York City began to offer free lunch to all students in 2017. Teachers In 1999, uncertified teachers filled an average of 10%, and as many as 27%, of the positions in the public school system. Beginning in 2000, after experiments with hiring uncertified teachers to fulfill a massive teacher shortage failed to produce acceptable results, and responding to pressure from the New York State Board of Regents and the No Child Left Behind Act, the DOE instituted a number of innovative programs for teacher recruitment, including the New York City Teaching
