In 2006, USDA introduced new language to describe ranges of severity of food insecurity. USDA made these changes in response to recommendations of an expert panel convened at USDA"s request by the Committee on National Statistics (CNSTAT) of the National Academies....The following labels define ranges of food security:
High food security (old label=Food security): no reported indications of food-access problems or limitations.
Marginal food security (old label=Food security): one or two reported indications–typlcally of anxiety over food sufficiency or shortage of food in the house. Little or no indication of changes in diet or food intake.
Low food security (old label=Food insecurity without hunger): reports of reduced quality, variety, or desirability of diet. Little or no indication of reduced intake.
