On the one hand, Ronald McDonald is being blamed pretty much single-handledly for the rise in children's obesity, and there are organizations calling for his resignation. On the other, Ronald McDonald is also the symbol of the good works of McDonald's like Ronald McDonald House.
Here's my two cents on the matter. No individual with a brain ever really thought McDonald's food overall was health food, although they certainly have made efforts to have some healthy choices--yogurt parfaits, fruit smoothies, oatmeal, grilled chicken, apple slices, side salads. So if a child wants McDonald's, it doesn't necessarily mean that it has to be unhealthy food.
And who is supposed to be deciding for a child between the healthy food McDonald's offers on its menu and the less than stellar choices? YES! The parent or guardian.
