Food deprivation is the restriction of free access to food, particularly in experimental settings where it is used as a technique to manipulate organisms to work for rewards and to establish levels of motivation.
In the wider context food deprivation can lead to hunger, starvation , nutritional deficiencies and malnutrition with broad impacts on cognitive functioning.
Famine and hunger[]
Food deprivation leads to malnutrition and ultimately starvation. This is often connected with famine, which involves the absence of food in entire communities. This can have a devastating and widespread effect on human health and mortality. Rationing is sometimes used to distribute food in times of shortage, most notably during times of war.[1]
Starvation is a significant international problem. Approximately 815 million people are undernourished, and over 16,000 children die per day from hunger-related causes.[2] Food deprivation is regarded as a deficit need in Maslow's hierarchy of needs and is measured using famine scales.[3]
