Malnutrition
A broad term for a range of conditions that hinder good health, caused by inadequate or unbalanced food intake or from poor absorption of food consumed. Refers to both undernutrition and overnutrition - conditions of both deprivation and excess.

Undernutrition
The result of prolonged low level of food intake and/or low absorption of food

consumed. Generally applied to energy (or protein and energy) deficiency, but may also relate to vitamin and mineral deficiencies brought on by a failure to maintain body stores of these nutrients.

Undernourishment
The status of persons whose food intake regularly provides less than their minimum energy requirements. Individuals whose food intakes consistently fall below their energy requirements are considered to be in a state of undernourishment.

Chronically undernourished
Those whose estimated annual energy intake falls below that required to maintain
body weight and support light activity.

Micronutrient deficiency
Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of absorption of food consumed.

Micronutrient malnutrition
Refers to vitamin and mineral deficiency disorders. Often occurs as part of general
undernutrition due primarily to overall inadequate food intakes (through poor access to
foods that are good sources of these nutrients or poor dietary habits).

Overnutrition
Result of excessive food intake in relation to energy requirements.

Energy requirements
Are determined by body size, activity level and physiological conditions such as illness,
infection, pregnancy and lactation.

Food security
Exists when all people at all times have both physical and economic access to sufficient, safe and nutritious food that meets their dietary needs for an active and healthy life.

Food insecurity
Exists when people lack access to sufficient amounts of safe and nutritious
food, and therefore are not consuming enough for an active and healthy life. This may be due to the unavailability of food, inadequate purchasing power, or inappropriate utilization at household level.
