You go to the market for milk with your kid. He begs for candy, pointing at a rack. You are forced to give in. Sound familiar? In supermarkets, important foods like milk, butter and eggs are in the last aisles so that along the way your children can beg for their favorite sweet treat. Unhealthy school lunches like hamburgers have more fat and processed beef every year. More and more, kids find this all as an opportunity to snack, and before they know it, they are obese. I think we should make fatty, processed and fast food less easy to get. Have school lunches be healthy food like chicken or fish. Put up more farmers' markets. Replace the candy racks at the market with magazines. Thirty percent of American children are obese. These little healthy changes will slowly but surely shrink that number drastically.
