Unhealthy foods

I watched a Ted talk video talking about how school lunches are so unhealthy. In Coopers voice presentation she discusses the concern she has for the students and what's given to them everyday. Study's show that the foods kids are given are just as bad as eating out at a fast food place. She wants to teach kids how to eat healthier and actually make healthy food appetizing. Organically grown and regionally grown foods is what she recommend many parents to buy, but the problem is organic foods are quite expensive for some family's to afford especially in a large house hold. About 70% of antibiotics are in our meats, and kids today are now consuming roughly five pounds of pesticides a year. Foods that we think are healthy for us is actually harming our body's, causing many kids and adults to be ill. The government doesn't really seem to care about the kids and the foods they allow them to eat, because facts show about $35,000 tax dollars are to maintain a prisoner and only $500 dollars are for the food given to kids a year. She blames the junk food and fast food advertisement because they manipulate children to want unhealthy meals which leads to an unhealthy diet. How could we fix this problem?
