4. The Twenty Qualities (Gurvadi Gunas)
Ayurveda describes every substance and every state of the body by ten pairs of opposite qualities. This is its most practical tool: like increases like, and opposites balance. If a guest is dry, constipated and cold (Vata qualities), the kitchen adds their opposites — moist, smooth and warm — through ghee, soups and warm spices.
| Quality | Opposite | Increases | Food examples (first quality) | Food examples (opposite) | |
|---|---|---|---|---|---|
| Heavy (guru) | Light (laghu) | Kapha / Vata | Urad, paneer, sweets, cheese, wheat | Moong, puffed rice, barley, steamed vegetables | |
| Slow (manda) | Sharp (tikshna) | Kapha / Pitta | Milk, rice, banana | Chilli, mustard, garlic, ginger | |
| Cold (shita) | Hot (ushna) | Vata–Kapha / Pitta | Cold water, cucumber, ice cream | Ginger, pepper, sesame, hot soup | |
| Unctuous (snigdha) | Dry (ruksha) | Kapha–Pitta / Vata | Ghee, sesame oil, avocado, coconut | Barley, millets, crackers, popcorn, beans | |
