Nutritional status during pregnancy can have a significant impact on maternal and neonatal health outcomes. Requirements for macronutrients such as energy and protein increase during pregnancy to maintain maternal homeostasis while supporting foetal growth. Energy restriction can limit gestational weight gain in women with obesity; however, there is insufficient evidence to support energy restriction during pregnancy.
Micronutrients, often referred to as vitamins and minerals, are vital to healthy development, disease prevention, and wellbeing. With the exception of vitamin D, micronutrients are not produced in the body and must be derived from the diet 1. Though people only need small amounts of micronutrients, consuming the recommended amount is important. Micronutrient deficiencies can have devastating consequences. At least half of children worldwide younger than 5 years of age suffer from vitamin and mineral deficiencies 2. The role of six essential nutrients is outlined below.
Micronutrients are one of the major groups of nutrients your body needs. They include vitamins and minerals.

Nearly 30 vitamins and minerals that your body cannot manufacture in sufficient amounts on its own are called "essential micronutrients. Even today in many low-income countries, people frequently suffer from a variety of nutrient-deficiency diseases. True vitamin and mineral deficiencies—in which the lack of a single nutrient leads directly to a specific ailment—are rare in the United States because our extensive supply of inexpensive food, and the fortification of many common foods with some key nutrients. However, eating less than optimal amounts of important vitamins, minerals, and other compounds can still contribute to a number of major illnesses, such as heart disease, type 2 diabetes, cancer, and osteoporosis.
Micronutrients are essential elements required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. The minerals for humans and other animals include 13 elements that originate from Earth's soil and are not synthesized by living organisms, such as calcium and iron. A multiple micronutrient powder of at least iron, zinc , and vitamin A was added to the World Health Organization's List of Essential Medicines in At the World Summit for Children , the gathered nations identified deficiencies in two microminerals and one micronutrient — iodine, iron, and vitamin A — as being particularly common and posing public health risks in developing countries.
