Obesity-parents the cause and solution?

I really like the Ted link that Ms. Fletcher posted called “Teach Every Child About Food”. He says that diet related disease is the biggest killer in America. The fact that it’s diet related means that we can control our diets and change it to reduce the amount of people dying from this disease. Many people believe that the parents are the main cause of the obesity epidemic. The reason for this is because they are the ones who feed them and are supposed to do what’s right for their kid. But many parents don’t know what to feed their kids or are too busy to cook or they just don’t know how to cook. What ever the reason, they give their children fast food and processed foods because it’s fast and cheaper than going to a grocery store and buying produce, which in my opinion shows that parents are the main cause for the obesity epidemic. There are many factors that caused the obesity epidemic, such as the fast food restaurants, and the government, and the way our society has evolved, but I believe that parents are the main cause and are the main solution to this problem. One solution for this would be, as Jamie Oliver said, to teach parents how to cook. He also said that kids should learn about food and what they are eating. They don't eat their vegetables because they don't know what it is. In the video, he asked elementary school kids to name the vegetables that he was holding, and they didn’t name any of them correctly.

Another cause for obesity is that if the parents are obese then most likely their kid will end up becoming obese because if their parents have poor eating habits and don’t exercise, then they will most likely raise their kids in this way. If parents are ignorant then their kids are more likely to become obese, so parents need to be taught about what to feed their children and how much to feed them. They also need to be taught how much daily exercise their kids should get.  Do you think that parents are to blame if their child is obese? If so, then what do you think parents should do to prevent/solve obesity? What do you think about this and how should we deal with this problem?
