Macronutrient and Micronutrient Intake during Pregnancy: An Overview of Recent Evidence

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. The Ottawa-based Micronutrient Initiative was formed in response to this challenge with the mission to undertake research and fund and implement micronutrient programming. As programming around these micronutrients grew, new research in the s led to the implementation of folate and zinc supplementation programmes as well. Priority programs include supplementation with vitamin A for children 6—59 months, zinc supplementation as a treatment for diarrhoeal disease, iron and folate supplementation for women of child-bearing age, salt iodization , staple food fortification, multiple micronutrient powders, biofortification of crops and behaviour-centred nutrition education.

While there are many essential nutrients, they can be broken into two categories: macronutrients and micronutrients. Macronutrients are eaten in large amounts and include the primary building blocks of your diet — protein, carbohydrates, and fat — which provide your body with energy. Vitamins and minerals are micronutrients, and small doses go a long way. There are six main groups of essential micronutrients and macronutrients. Protein is having its moment, and not just in the workout community. But all of the hype is for a good reason. Protein is essential for good health.

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. Modulating carbohydrate intake via a reduced glycaemic index or glycaemic load diet may prevent gestational diabetes and large-for-gestational-age infants. Certain micronutrients are also vital for improving pregnancy outcomes, including folic acid to prevent neural tube defects and iodine to prevent cretinism. Newly published studies support the use of calcium supplementation to prevent hypertensive disorders of pregnancy, particularly in women at high risk or with low dietary calcium intake. Although gaps in knowledge remain, research linking nutrition during pregnancy to maternofoetal outcomes has made dramatic advances over the last few years.

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.

Micronutrient

To maintain your brain, muscle, bone, nerves, skin, blood circulation, and immune system, your body requires a steady supply of many different raw materials—both macronutrients and micronutrients. You need large amounts of macronutrients—proteins, fats, and carbohydrates. And while you only need a small number of micronutrients—vitamins and minerals—failing to get even those small quantities virtually guarantees disease. 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.

Macronutrients are those nutrients that the body needs in large amounts. These provide the body with energy calories. Micronutrients are those nutrients that the body needs in smaller amounts.

Micronutrients are one of the major groups of nutrients your body needs. They include vitamins and minerals. Vitamins are necessary for energy production, immune function, blood clotting and other functions. Meanwhile, minerals play an important role in growth, bone health, fluid balance and several other processes. This article provides a detailed overview of micronutrients, their functions and implications of excess consumption or deficiency.
