"Americans have done a great job making sure that our kids have something to eat at school regardless of socioeconomic status, with the National School Lunch Program providing low-cost or free lunches to upwards of 31 million students at 92 percent of U.S. public and private schools. But that doesn't mean the food has been especially nutritious, and public health experts say it's no wonder our kids are more obese than ever when we feed them trans fats, salts and sodas for lunch. Kids get half their daily calories at school, so what's for lunch there has a big impact on health and lasting eating habits. A 2008 analysis of school lunches by the Institute of Medicine (IOM) concluded that American kids consume very few fruits and vegetables in their cafeterias-with potatoes accounting for a third of all vegetables consumed. IOM also found that kids were eating many refined grains and too much saturated fat and sodium. A 2009 study by USA Today found that meat used by McDonald's and Burger King was tested for bacteria and unsafe pathogens up to 10 times as much as meat bound for U.S. school cafeterias. In response to these stark findings, along with vigorous advocacy by First Lady Michelle Obama, things are starting to improve. In 2010, Congress voted to revamp the nation's school lunch program by enacting the Healthy, Hunger-Free Kids Act (HHFKA). The higher standards in the new law seek to align school meals with the federal 2010 Dietary Guidelines for Americans by upping the availability and portion sizes of fruits, vegetables and whole grains (and requiring students to select a fruit or vegetable), establishing calorie ranges, removing trans fats and limiting sodium levels. The law also incentivizes schools to take part with generous meal reimbursement funds. The new standards went into effect in 2012 and have been working their way through school districts from coast-to-coast and getting rave reviews in the process. Researchers from the Harvard Schoo
