Three Types of Food
Foods that increase life, purity, strength, health, happiness, and satisfaction are dear to those in sattva.
Krishna extends the guna analysis to diet. Sattvic foods are fresh, nourishing, and pleasant—they promote health and clarity. Rajasic foods are overly stimulating—too salty, sour, or hot. Tamasic foods are stale, impure, or harmful. What we eat affects our consciousness. This teaching has influenced vegetarian practices and mindful eating. Modern nutrition science confirms that diet affects mental and emotional states, validating this ancient wisdom.
Foods dear to those in the mode of goodness increase the duration of life, purify one's existence, and give strength, health, happiness, and satisfaction.
Ayurveda elaborates this dietary wisdom extensively—we are what we eat, and conscious eating is spiritual practice.
