Food plays an important role in the maintenance of fine health and both in the prevention and cure of diseases. According to Sir Robert McCarrison ‘, The correct reasonably of food is the most significant single factor in the promotion of health; and the wrong kind of food is the most important single factor in the promotion of disease’. In other words, nutrition depends upon food and is also of utmost importance in the cure of disease. Nutrients are required for the build-up and maintenance of healthy cells, tissues, glands, and organs that aid in metabolic, hormonal, mental, physical, or chemical activities of the physique. It is reported that a minimum of 45 essential nutrients are needed by human cells. These include oxygen, water, and five major groups namely carbohydrates, fats, proteins, minerals, and vitamins. All 45 of those nutrients are vitally important and they function together and the absence of any of them will lead to disease and eventually death.
