According to the article below, half of the U.S. will be obese by 2030. The stated solution is to have the government market healthier foods more aggressively and to educate the people more on how to eat. But in our mixed economic system it is difficult for the government to step in and play down foods like McDonald's, Pizza Hut, and Taco Bell when they are at such a high demand. People like to eat good tasting, cheap food, but right now in America the healthier foods have to go through a more rigorous test to get put out on shelves at stores and therefore raising the price of this good. Since healthier foods are not a necessity to Americans they are an elastic good, which also means that the rise of price for these healthier foods will cause the quantity demanded to decrease according to the Law of Demand. So basically the solution is to raise the demand for the goods by lowering the price for the public and marketing the healthier products more to make them more desired. This is just an economic solution to obesity, but it is largely based off of individual's decisions. For example it is very difficult for a person after they just ate three grilled stuffed burritos from Taco Bell for $5, to give that up the next meal and eat a healthier food that cost twice that of Taco Bell. Healthy eating is a habit that must be perfected day by day, it's not always the most enjoyable activity. But more aggressive marketing and the lowering of prices on these healthy foods could lead many Americans to be more willing of eating healthy.
