Quick Reference

Double Burden of Malnutrition

The coexistence of undernutrition (stunting, wasting, micronutrient deficiencies) and overnutrition (overweight, obesity, diet-related noncommunicable diseases) within the same population, household, or even individual over a lifetime.

Food Security

A condition that exists when all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life, as defined by the 1996 World Food Summit.

Dietary Reference Intakes (DRIs)

A set of reference values including Estimated Average Requirements, Recommended Dietary Allowances, Adequate Intakes, and Tolerable Upper Intake Levels used by public health professionals to plan and assess nutrient intakes of populations and individuals.

Nutrition Transition

The shift in dietary consumption patterns that accompanies economic development, urbanization, and globalization, typically moving from traditional diets high in fiber and whole grains to diets high in added sugars, refined fats, and animal-source foods.

Food Fortification

The deliberate addition of one or more essential micronutrients to a commonly consumed food at the point of processing to improve the nutritional quality of the food supply and provide a public health benefit with minimal risk.

Micronutrient Deficiency

Insufficient intake or absorption of vitamins and minerals required in small amounts for normal physiological function, also called hidden hunger because clinical signs may not be visible even as deficiency impairs health, growth, and cognitive development.

Social Determinants of Nutrition

The economic, environmental, political, and social conditions in which people are born, grow, live, and work that shape their dietary patterns and nutritional status, including income, education, food environment, cultural norms, and systemic racism.

Nutritional Epidemiology

A branch of epidemiology that studies the relationship between dietary exposures and health outcomes at the population level, using tools such as food frequency questionnaires, dietary recalls, and biomarkers of nutrient status.

Stunting

A form of chronic undernutrition defined as height-for-age more than two standard deviations below the WHO Child Growth Standards median, reflecting cumulative effects of inadequate nutrition and repeated infections during the first 1,000 days of life.

Ultra-Processed Foods

Industrial formulations made mostly or entirely from substances derived from foods and additives, with little if any intact food, as classified by the NOVA food classification system. They are typically energy-dense, high in added sugar, sodium, and unhealthy fats, and low in fiber and micronutrients.

Key Terms at a Glance

Anthropometry:The measurement of the human body, including height, weight, and body circumferences, used to assess nutritional status in populations.
Biofortification:The process of breeding crops to increase their nutritional value, such as developing orange-fleshed sweet potatoes with higher beta-carotene content.
Body Mass Index:A measure of body weight relative to height (kg/m^2) used for population-level screening of underweight, overweight, and obesity.
Chronic Undernutrition:Long-term insufficient nutrient intake leading to stunting and impaired development, often originating in early childhood.
Codex Alimentarius:International food standards developed jointly by FAO and WHO to protect consumer health and ensure fair food trade practices.
Complementary Feeding:The introduction of nutritionally adequate solid and semi-solid foods alongside breast milk beginning at six months of age.
Dietary Reference Intakes:A set of nutrient intake reference values (EAR, RDA, AI, UL) used to plan and assess the diets of populations and individuals.
Double Burden of Malnutrition:The coexistence of undernutrition and overnutrition within the same population, community, or household.
Exclusive Breastfeeding:Feeding an infant only breast milk with no other food or liquid for the first six months of life, as recommended by WHO.
Food Desert:A geographic area with limited access to affordable and nutritious food, often lacking grocery stores or supermarkets.
Food Fortification:The addition of essential micronutrients to widely consumed processed foods to improve the nutritional quality of the food supply.
Food Security:The condition in which all people at all times have access to sufficient, safe, and nutritious food for an active and healthy life.
Food Sovereignty:The right of peoples to define their own food systems, policies, and agricultural practices, emphasizing local control over food production.
Hidden Hunger:Micronutrient deficiencies that may not produce visible clinical signs but impair health, growth, immunity, and cognitive development.
Iodine Deficiency Disorders:A spectrum of health problems caused by insufficient iodine intake, including goiter, hypothyroidism, and impaired cognitive development.
