 There are 27 essential micronutrients that our bodies need to survive. Among them, the most important of these are iron, iodine, vitamin A, zinc, and folate. Globally, more than 2 billion people are affected by a deficiency in these micronutrients, which can lead to devastating consequences. These important nutrients are responsible for managing many different processes in your body. In this video, I'll give you a quick rundown on the functions and importance of each one. Iron With iron, think blood and brains. In order for your body to make hemoglobin, the substance that carries oxygen through your blood to all the cells in your body, it needs iron. Iron is also responsible for the proper function of neurotransmitters. Without iron, the neurochemicals in your brain can't deliver messages from one nerve to another, leaving your brain a spacey, tired mess. Iodine The most important role iodine has in your body is to make thyroid hormones. Your thyroid gland uses iodine to properly regulate your metabolism, as well as the development of your bones and brain. Vitamin A Vitamin A plays an important role in the growth and development of several systems in the body. As its chief function, vitamin A supports your eyes by creating pigments that are essential in keeping the retina of the eye healthy. Vitamin A also helps support the development of teeth and provides a barrier against infections of the skin, lungs and mouth. Zinc Zinc is needed for your body to fight off invading bacteria and viruses, and is also important in the development of your nervous system. Zinc has been known to treat anything from the common cold to skin wounds. Folate Folate is needed for our bodies to make DNA and divide cells. Taking folic acid regularly before becoming pregnant and during early pregnancy helps prevent neural tube defects in babies. Also, research has shown that people with low blood levels of folate are more likely to suffer from depression and might not respond as well to treatment with antidepressants.
