Everything we eat or drink falls under one of these six tastes. Vata is stimulated by pungent, bitter and acid, and weakened by sweet, sour and salt. It would be advisable for a vata person to eat food that is sweet, sour or salty. Everything that stimulates vata weakens kapha and vice versa. Kapha then is stimulated by sweet, sour and salty and is weakened by pungent, bitter and acid.
Pitta is stimulated by pungent, sour and slightly salty and weakened by sweet, bitter and acid.
In our example horoscope we had a vata-pitta constitution. An anti-vata diet consists of the tastes sweet, sour and salt. However, sour and salt stimulate pitta. The emphasis in the diet of someone with a vata-pitta constitution will then be on sweet tastes. This will stimulate kapha, which Kennedy lacks.
