As long as the metabolic events continue, all living beings need more than 50 nutrients or chemical compounds and energy to live. Energy is spent every day at rest (basal metabolism) and during physical activity. Basal metabolism is required to restore the basic function of the body, such as respiration, heartbeat, etc. through metabolic pathways that are regulated by minerals, vitamins, hormones, and enzymes. Every nutrient group should be identified in balanced diet. During daily feeding, nutrients that are taken in a lot quantities are macronutrients, whereas micronutrients are nutrients that human’s body needs in lesser quantities. Macronutrients are classified into three types, carbohydrates, proteins, and fats, whereas micronutrients are classified into three building blocks, glucose, amino acid, and fatty acid. Carbohydrates are classified into 2 types, monosaccharides (glucose, fructose, galactose) and disaccharides (sucrose, lactose, maltose). Polysaccharides are polymers formed by the combination of a large number of monosaccharide monomers, such as starch, glycogen, cellulose, inulin, and pectin. Micronutrients are classified as vitamins, water soluble vitamins, minerals, and water.
