In Bitman and Waters articles, both discuss the harmful, low-quality foods being willingly served to the public by the government. In Bad Food? Tax it and Subsidize Vegetables, points out the failings of the government in making healthy food an obtainable necessity. By keeping up this industry of low cost, low quality junk food, public health risks are at an all-time high. He offers some solutions to this epidemic, including taxing unhealthy foods to help subsidize the price of healthier food alternatives, that could help solve this very serious epidemic. In the same vein as Mark Bitman's article, Alice Waters and Katrina Heron call for a public school nutrition reform in their article No Lunch Left Behind. With school lunches given scraps in terms of food and funding, children who rely on these school lunches are left to suffer. By putting more care, funding, and research into the school lunch system, a change can be made that will make the system cheaper and healthier in the long run.
