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.

Ayurveda has categorized personality traits into three different kinds, based on the food we eat - the Satvic or spiritual quality, Rajasic or active quality, and Tamasic or material quality of the mind is all affected by the food we eat. The activating Rajasic quality may dominate or combine with the other two qualities to form different mental tendencies in man; spiritually active, intellectually active, or materially active. Satvic food is elevating while Rjasic foods lead man to a materialistic, selfish way of living. Worst is Tamasic food, which leads to a devilish streak in a person.

The bane of today's generation is that they are Tamasic personalities. Self-centered, insecure and ailing, they are reaching a point of no return. The very food that has become an epitome of fashion is of unhealthy nature. We are leaving the wisdom of Satvic food and rushing towards the ills of an unhealthy Tamasic diet. No wonder our society is degenerating into a violent, self-seeking, power hungry and uncaring one.
