Fork Over Knives

What do you think this documentary is going to be about ? I think this documentary is going to be about how America has more obese people than any other country's , and how the United States is trying to give a message that we need to be more healthy. Also that they scare that the children are going to live less than there parents because of chunk food!. What do you think the title implies or indicates the film ? The tittle implies about food and that they are not responsible for any activity's and that what they about to see doesn't mean that you have to do it.
