After a five-year drought, chocolate and strawberry milk are making their way back into public school lunchrooms in Los Angeles. With a vote of 6 to 1, the Los Angeles Unified School District loosened a district-wide ban on sugary, flavored milk that took effect in 2011. The board approved a pilot program to study the effects of reintroducing flavored milk in a small group of schools, all of which must volunteer to take part in the experiment. t is not that board members believe children aren’t consuming enough sugar. Rather, the decision to re-examine milk offerings stemmed from concern that the district is throwing out an obscene amount of food — 600 tons of organic waste each day, according to a 2015 district study. Much of what’s being taken to the landfill is the plain milk that schools are encouraged by federal law to offer, but that students aren’t enthusiastically drinking.
