Micronutrients, Do We Really Need Them?


Food can be split into two categories; macronutrients and micronutrients. Macronutrients are the foods that we need to take in big quantities which are proteins, fats and carbohydrates. Micronutrients are those that are needed by the body in small or minute quantities and these include vitamins, minerals, fatty acids, phytonutrients and amino acids. There are about 53 known micronutrients. Though they are only needed in small quantities, a lack of micronutrients can lead to adverse health effects including deficiency diseases.
