A famine food or poverty food is any inexpensive or ready available food used to nourish people in times of hunger and starvation, whether caused by extreme poverty, such as during economic depression or war, or by natural disasters such as drought.
The characterization of some foodstuffs as "famine" or "poverty" food can be social. For example, lobster and other crustaceans have been considered poverty food in some societies and luxury food in others, depending on the period and situation. [1]
Several foodstuffs have been strongly associated with famine, war, or times of hardship throughout history:
