Hike in Food Prices- MSNBC Article

Most people probably haven't noticed, or if they have they aren't complaining much about it. It seems in the recent years the cost of food has increased by about 5%. With an increase in energy costs and the cost of production of wheat and corn it seems that supermarkets all over the United States are changing their price stickers. I read the article on www.msnbc.com, it was titled "Food price hikes changing U.S. eating habits: More people say they are eating at home, buying food in bulk"
The article is a brief one, but the idea of it is shocking. Is it true will an increase in the price of food have a dramatic result on America's eating and shopping habits. I almost believe that this might be a good thing. If we eat out less we are less likely to eat fast food. If the pre-packaged food costs more we will be eating less. Is this America's sneaky attack at fighting the obesity epidemic?
