"Food insecurity refers to USDA’s measure of lack of access, at times, to enough food for an active, healthy life for all household members and limited or uncertain availability of nutritionally adequate foods." (1)

"Food insecurity may reflect a household’s need to make trade-offs between important basic needs, such as housing or medical bills, and purchasing nutritionally adequate foods." (1)

Those who face food insecurity are not only described as hungry, but also, “report being unable to afford balanced meals, worrying about the adequacy of their food supply, running out of food, and cutting the size of meals or skipping meals” (2)

Food insecurity also describes when, "families don't regularly have enough food to eat, the most basic of all human needs." (3)
