Hidden starvation essentially represents the absence of human essential vitamins and minerals (collectively called micronutrients) with no signs or symptoms of micronutrient deficiency. The discovery of essential vitamins and minerals has a long history and has had considerable success in preventing and treating classic deficiencies associated with illness, scurvy and anemia. Recently it has been recognized that even if there are no obvious signs of illness, insufficient intake of micronutrients may affect health.

The term recessive starvation refers to a less insidious deficiency caused by eating cheap and adequate but essential vitamins and foods lacking micronutrients. Although the results of subclinical deficiency of micronutrients are easy to understand and monitor, they are often not noticed. Community For these reasons micronutrient deficiency is known as "hidden starvation". Micronutrient shortages may even exist in communities where food supply is sufficient to meet the demands of the population's energy. Disadvantages are inevitable if people can not use foods of animal origin, including fruits, vegetables, micronutrients, enough to disperse meals.

"Hidden starvation" is a term used to describe the lack of essential vitamins and minerals in the body, also known as micronutrients. Micronutrient deficiency affects an estimated 2 billion people, nearly a third of the world's population (1). Deficiency of iodine, iron, vitamin A and zinc are the four major micronutrient deficiencies in the world's largest public health problem, due to their high prevalence and associated health and developmental impact. Approximately one-third of children aged 6-59 years (under 5 years old) have vitamin A deficiency (VAD) in middle and low income countries (2), 18% of children under 5 years old are iron Like anemia (3), 30% of people worldwide suffer from inappropriate iodine intake (4), but ingestion of zinc by 17% is insufficient (5). These gaps at the population and individual levels overlap and the full range of numerous defects remains unrecognized, but hidden starvation is still a global challenge.
