Micronutrient deficiencies are known to affect more than two billion people globally [1]. The magnitude of the problem is much greater in low-income countries, where multiple micronutrient deficiencies often occur concurrently as a result of poor-quality diets [2]. Suboptimal dietary intake of micronutrients during pregnancy has been associated with low micronutrient status, poor foetal growth, preterm delivery, poor infant survival, and increased risk of chronic diseases in later life [1,3,4]. Hence, adequate micronutrient status and good dietary practice during pregnancy are necessary to achieve healthy birth outcomes. This Special Issue on “Micronutrients and Pregnancy” has collated eight manuscripts, of which four are original articles and four are reviews.
