According to Ayurveda there should be 06 raas in food. Or 06 tastes in food. Those are Sweet, Sour, Salty, Spicy, Bitter and Astringent like. Now lets take a quick run on what these tastes are. Sweet everyone knows It should be purest form than the processed form. Sour means like tamarind or lemon. Salty we all know. Spice is like green chilly taste or jalapeno. Bitter is like bitter gourd or pure cocoa like taste and Astringent taste is if you have tasted goose berries or alum. All the time we were doing it wrong. Food is not by count of proteins, or calories count. It should have all these 06 tastes mentioned.
