It isn't enough that the food supply has been reduced to this (the whole NYT article is worth a read):

"So how is it that today the people with the least amount of money to spend on food are the ones most likely to be overweight? ... Drewnowski gave himself a hypothetical dollar to spend ... [he] found that a dollar could buy 1,200 calories of cookies or potato chips but only 250 calories of carrots. Looking for something to wash down those chips, he discovered that his dollar bought 875 calories of soda but only 170 calories of orange juice."

Now they have to go after chocolate!, apparently, the demand for chocolate isn't enough for a profitable and satisfied Hersheys:

"The US Food and Drug Administration is considering redefining 'chocolate' to allow substitution of vegetable oil ($0.70/lb.) for cocoa butter ($2.30/lb.), and whey protein for dry whole milk"
