Micronutrients & recovery
Calcium, iron, vitamin A, and zinc are the micronutrients with the lowest levels of adequate estimated intake globally, with strong regional variations in which specific nutrients are most deficient.
Focus on ensuring adequate intake of calcium, iron, vitamin A, and zinc, as these are the most commonly deficient nutrients globally. Tailor your diet to address specific regional deficiencies (e.g., iron and vitamin A in South Asia, calcium and folate in Southeast Asia).
GoodSupportsHIGH confidence
At the global level, micronutrients with the lowest levels of adequate estimated intake are calcium, iron, vitamin A, and zinc, but there are strong differences between countries and regions.
Why this rating
Based on comprehensive global modeling of 14 micronutrients.

- Global dietary micronutrient supplies have improved over the last 50 years, but sub-Saharan Africa is the only region where micronutrient density has declined due to a shift toward lower-density staples like rice and maize.Good
- Food fortification significantly reduces the prevalence of inadequate micronutrient intakes in low-income regions, particularly for iron, vitamin A, and zinc, although its effectiveness varies by region and specific nutrient.Good
