Percent of the population with inadequate niacin intake

Definition

The percent of the population estimated to have inadequate niacin intake from their diets. Estimates are based on modelled dietary intake data and do not include fortification or supplementation.

Relevance

Micronutrient deficiencies are among the most common forms of malnutrition and most of the global population has inadequate intake of at least one micronutrient. Niacin is important for energy metabolism. Deficiency can cause skin rashes, digestive issues, and neurological problems that can progress to dementia. Estimates of inadequate intakes can help identify where interventions are needed to improve people’s health.

Additional Information

Estimates are based on modelled dietary intake of scarce data and assume equal caloric intake across countries. This leads to an underestimate of inadequate intakes in countries with lower caloric intake and an overestimate of inadequate intakes in countries with higher caloric intake.
