I was told that ayurveda means
the study of life

Which today in English would be called *Biology*

I remember there are 3 Doshas
Vatta, Pitta, and one more?

This made me think of Todays diet guide based on the 3 (main) blood types.

I know little about ancient ayurveda but saw there was no post on this topic so perhaps others will add to this.
