Ayurveda, India's ancient medical system, divides food into three categories: Satvic, Rajasic, and Tamasic. Satvic food is made up of all natural and minimally processed ingredients, such as vegetables, and is thought to have a positive, calming, and purifying effect on the body and mind. Rajasic food is spicy, oily, salty, or bitter, and it fuels ambition, competition, and egotistical desires. Tamasic food is highly processed, toxic, and difficult to digest, and it has a negative impact on both the mind and the body.
