Question to TKV Desikachar:
What is the relationship between diet and health?

TKV Desikachar Response:
It is a big subject. Our system has to be nourished. Food or Annam is needed. There is the Annamaya, we have a body which has to be nourished. The food we need and eat is Annam.

“Annam is that which will nourish you or that which will eat you.”

This Annam is a very interesting Saṃskṛta word. Annam is that which will nourish you or that which will eat you. The Annam or food must nourish me, it should not consume me. For this reason there is given so much importance to Annam that nourishes and Annam that will consume.
