Long before we had heard of carbs-fats-proteins,or came to know of nutrition, food pyramids, RDA’s (recommended daily allowance), ayurveda came up with a list of six distinct tastes to formulate a balanced diet. As ayurveda originated thousands of years back, the wisdom and knowledge was shared in an oral communication (communication language was not written) and was passed on by one person to another. It was much later that the vedic scholars compiled them into ayurvedic texts/vedas.
Incorporating all these six tastes in our daily meals, leads us to eating a balanced diet. I call this the “vedic taste chart”!
