Packaged-food companies are hoping the U.S. comes down with a serious case of the munchies. At least, we can assume that's the idea given the amount of growth packaged-food companies hope to see from their snacks businesses.

MarketWatch reports packaged-food companies plan to "capitalize on American consumers who continue to snack more throughout the day." They also expect to see growth from developing markets, which have more women entering the workforce -- target munchers.

Gary Stibel, chief executive of the New England Consulting Group tells MarketWatch people are busier than they used to be, and the trend is growing. As a result, "you and I will continue to snack more and sit down to a meal less."

So how much growth are we talking about? The roughly $560 billion snack market hopes to see higher demand, increase prices, and toll out with new snack products. Possibilities seem limitless.

"There's plenty of room" for growth for all the smaller and larger players in the field. "The global market's very fragmented," said Lee Linthicum, Euromonitor's head of global food research.
