WASHINGTON (Reuters) - More than 49 million Americans -- one in seven -- struggled to get enough to eat in 2008, the highest total in 14 years of a federal survey on "food insecurity," the U.S. government said Monday.

While Agriculture Secretary Tom Vilsack said programs such as food stamps softened the impact of an economic recession, anti-hunger groups pointed to the huge increase from the preceding year when 36.2 million people had trouble getting enough food and a third of them occasionally went hungry.

"The survey suggested that things could be much worse but for the fact that we have extensive food assistance programs," Vilsack told reporters. "This is a great opportunity to put a spotlight on this problem."

About 14.6 percent of U.S. households, equal to 49.1 million people, "had difficulty obtaining food for all their members due to a lack of resources" during 2008, up 3.5 percentage points from 2007 when 11.1 percent of households were classified as food insecure.
