Very informative article. Thanks. I think child obesity can be prevented. I know that weight problems can be genetic but also, the parents can control what they and their young child puts in their mouth and eats, have more physical activity. I think that if we want children to eat healthy parents have to put an example. Because parents always tell their children not to eat junk food but some parents still buy sodas and chips, and when they dont do dinner the kids eat macaroni and cheese or pizzas whatever they could make. I think the parents should be the first to eat healthy and show an example to their kids that way the kids will maybe understand more and actually obey.
