"When diet is wrong, medicine is of no use. When diet is right, medicine is of no need".
Digestion, and therefore diet, are hugely important in Ayurveda. It is literally a case of "you are what you eat" (or perhaps "you are what you digest"!), and food is a medicine as well as a daily fuel. Everything we eat has the ability to either heal or harm us as individuals, and what is medicine for one person might be poison to another. There are no good or bad foods in Ayurveda, just foods that should either be chosen or avoided depending on a person's constitutional type. Processed foods, though, should be avoided by everyone.
An Ayurvedic diet is based around full use and awareness of the six main tastes: sweet, salty, sour, pungent, astringent, and bitter. Each taste has an effect on the elements in the body, and therefore on the balance of the doshas. The sweet taste, for example, is made up mainly of earth and water, and so increases Kapha while decreasing Vata and Pitta. The salty taste is composed mainly of water and fire, and so increases Kapha and Pitta while decreasing Vata. All six of the tastes are essential for proper balance in the body, and it is vital that the digestive system is healthy so that the full benefit can be gained.
"The more you let Ayurveda and Yoga become the basis for your living, the easier living gets"
Yoga and Ayurveda are complimentary sciences, born from the ancient Vedic culture of India. There are so many links between them that it is actually quite hard to practice one without at least dipping into the other, even unintentionally! They share much of a common philosophy, and are both concerned with the balancing of body, mind and spirit.
There are several ways you can bring Ayurveda into your Yoga practice. Many asanas, for instance, can be used for balancing or pacifying a particular dosha. Slow, grounding, stabilizing asanas such as Savasana and forward bends can really help to balance Vata, while twists and backbends are great for releasing the heat of Pitta. Kapha tends to benefit from a warming, stimulating practice such as Surya Namaskar. Try incorporating a short Yoga practice into your morning routine to help balance your body and mind before the rest of the day kicks in. You could even end your practice with a short self massage, bringing in the element of touch.
