Ayurveda is a vast and ancient medical science. Unlike other medical sciences, instead of focusing on treatment of any particular disease, Ayurveda focuses more on the healthy living and well-being of the patient. For healthy living, Ayurveda emphasizes on consuming right kind of diet which is healthy and nutritious. According to Ayurveda, there are positive and negative attributes of diet. Since, Ayurveda deals with a holistic approach to healing; it covers the diet factor in depth. In Ayurveda, food is considered not only as mixture of the basic ingredients like proteins, vitamins, fats and carbohydrates, but it directs to avoid those food articles which are having opposite attributes to be used at same time as per Ayurveda. These sort of food may induce the accumulation of toxins in the body which may end up in chronic and grave diseases like cancer, immune disorders.
Diet is considered to be vital for a human body as it provides the basic nutrients, which are necessary to carry out the basic activities of digestion and metabolism. Ayurveda has categorized food into three types based on its basic quality-the Satvic or spiritual quality, Rajasic or active quality, and Tamasic or material quality. It is said that whatever food we eat affects our mind in accordance with its basic quality. Satvic food is enriching and elevating the level of energy for mind and soul, while Rajasic food has a basic tendency to provoke man to a materialistic and selfish way of living. Tamasic food is one, which leads to a devilish streak in a person.
