What term describes a condition resulting from a diet deficient in one or more nutrients?

The term that describes a condition resulting from a diet deficient in one or more nutrients is known as undernutrition. This condition occurs when an individual does not consume sufficient amounts of essential nutrients, leading to a variety of health issues. Undernutrition can manifest in several forms, including vitamin deficiencies, mineral deficiencies, and caloric deficiencies, all of which can severely impact physiological functions and overall health.

Malnourishment is a broader term that can include both undernutrition and overnutrition, making it less specific to just nutrient deficiency. Overnutrition refers to the excess intake of nutrients, which can lead to obesity and related health problems, while hypervitaminosis specifically indicates an excess of vitamins, particularly fat-soluble ones, in the body. Understanding these distinctions helps in identifying and addressing nutritional issues more effectively.
