Overnutrition

Overnutrition (pronunciation: /ˌoʊvərnʊˈtrɪʃən/) is a form of malnutrition where the intake of nutrients is oversupplied. The term can also refer to the overconsumption of specific nutrients, such as protein, fat, or carbohydrates.

Etymology

The term "overnutrition" is derived from the prefix "over-", meaning "too much", and "nutrition", which refers to the process of providing or obtaining the food necessary for health and growth.

Definition

Overnutrition occurs when the energy intake exceeds the energy expenditure. This can lead to an excess storage of energy, primarily in the form of fat. Overnutrition can also refer to the overconsumption of specific nutrients, such as vitamins and minerals, which can lead to toxic effects.

Causes

The primary cause of overnutrition is an energy imbalance between calories consumed and calories expended. Other contributing factors may include a lack of physical activity, excessive consumption of energy-dense, nutrient-poor foods, and genetic susceptibility.
