In 2010, 14.5 percent of households were similarly "food insecure" at some point, USDA says.
"In 2011, 5.7 percent of U.S. households (6.8 million households and one-third of all food-insecure households) had very low food security. In these households, the food intake of some household members was reduced and normal eating patterns were disrupted at times during the year due to limited resources."
In other words, people went hungry.
An estimated 5.4 percent of households suffered such "very low food security" in 2010.
Earlier, NPR's Pam Fessler reported for our Newscast Desk that the food security report "comes a day after the agriculture department reported that food stamp usage hit an all-time high in June. In June, 46.7 million people received what are now called supplemental nutrition assistance program, or SNAP, benefits."
