Nutrition
Nutrition, also called nourishment, is the provision to cells and organisms of the materials necessary in the form of food to support the life of human beings. Our food is made up of essential, natural substances called nutrients. There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. These nutrients can be grouped as macronutrients and micronutrients. The macronutrients are needed in large quantities, e.g. carbohydrates, fats (lipids), and proteins, and are building blocks of the body. The micronutrients, e.g. minerals salt, and vitamins are needed in fine quantities and are crucial for their role in metabolic pathways and in enhancing immunity.
