据估计，85.1%的美国家庭在2011年全年都有食物保障，这意味着他们在任何时候都能获得足够的食物，让所有家庭成员过上积极健康的生活。其余家庭（14.9%）在一年中至少有一段时间粮食不安全，其中5.7%的家庭粮食安全水平非常低，这意味着由于家庭缺乏资金和其他粮食资源，一名或多名家庭成员的食物摄入量减少，他们的饮食模式在一年中有时被打乱。极低粮食安全发生率从2010年的5.4%上升到2008年和2009年的水平。总体粮食不安全状况的变化（2010年为14.5%）在统计上并不显著。典型的粮食安全家庭在食品上的花费比相同规模和家庭构成的典型粮食不安全家庭多24%。在2011年调查之前的一个月中，57%的粮食不安全家庭参加了三个最大的联邦食品和营养援助计划中的一个或多个。
An estimated 85.1 percent of American households were food secure throughout the entire year in 2011, meaning that they had access at all times to enough food for an active, healthy life for all household members. The remaining households (14.9 percent) were food insecure at least some time during the year, including 5.7 percent with very low food security—meaning that the food intake of one or more household members was reduced and their eating patterns were disrupted at times during the year because the household lacked money and other resources for food. The prevalence rate of very low food security increased from 5.4 percent in 2010, returning to the level observed in 2008 and 2009. The change in food insecurity overall (from 14.5 percent in 2010) was not statistically significant. The typical food-secure household spent 24 percent more on food than the typical food-insecure household of the same size and household composition. Fifty-seven percent of all food-insecure households participated in one or more of the three largest Federal food and nutrition assistance programs during the month prior to the 2011 survey.
