A famine food or poverty food is any inexpensive or readily available food used to nourish people in times of hunger and starvation, whether caused by extreme poverty such as during economic depression or war; it can also be caused by natural disasters, such as drought. Foods associated with famine need not be nutritionally deficient, or unsavoury. People who eat famine food in large quantity over a long period of time may become averse to it over time. In times of relative affluence, these foods may become the targets of social stigma and rejection.
