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. Read More external icon.

Macro and micronutrients

Robin W. During the past decade, we have gained new insights into the profound effects that essential micronutrients and macronutrients have on biological processes ranging from cellular function, to whole-organism performance, to dynamics in ecological communities, as well as to the structure and function of ecosystems. For example, disparities between intake and organismal requirements for specific nutrients are known to strongly affect animal physiological performance and impose trade-offs in the allocations of resources. However, recent findings have demonstrated that life-history allocation trade-offs and even microevolutionary dynamics may often be a result of molecular-level constraints on nutrient and metabolic processing, in which limiting reactants are routed among competing biochemical pathways. In addition, recent work has shown that complex ecological interactions between organismal physiological states such as exposure to environmental stressors and infectious pathogens can alter organismal requirements for, and, processing of, nutrients, and even alter subsequent nutrient cycling in ecosystems.

Read time: 5 mins. Eating high quality foods is essential in nourishing the body and protecting it from inflammation and oxidative stress. The nutrients your body needs to promote growth and development and regulate bodily processes can be divided into two groups: macronutrients and micronutrients. Macronutrients are the nutrients your body needs in larger amounts, namely carbohydrates, protein, and fat. Micronutrients are the nutrients your body needs in smaller amounts, which are commonly referred to as vitamins and minerals.

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. Your body needs smaller amounts of micronutrients relative to macronutrients.


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. Click on the links below to discover the functions, recommended dietary intake, and food sources of the different nutrients our bodies need. Special considerations may need to be taken for individuals following a special diet e.
