Percent of the population with inadequate selenium intake

Definition

The percent of the population estimated to have inadequate selenium 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. Selenium is a powerful antioxidant and is important for thyroid and immune function. Deficiency can cause muscle weakness, heart problems, and increased susceptibility to infections. 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.
