If one would consider Ayurveda as part of Veda or Vedic scriptures, then the question would be best dealt with by the Ayurveda itself.
According to Dr.Vasant Ladd in his book ‘Ayurveda- The science of self healing, He opines as follows:-
“It is food that nourishes the body, mind and consciousness. How you eat is very important. While eating, one should sit straight and avoid distractions such as television, conversation or reading. Focus your mind upon and be aware of the taste of the food. Chew with love and compassion and you will clearly experience the taste.
Taste does not originate in food, it originates in the experience of the one who eats. If your agni is impaired, you will not taste the food properly. The taste of food depends upon agni. Spices help to enkindle agni, as well as to cleanse the body and to enrich the taste of the food. Each mouthful should be chewed at least thirty-two times before it is swallowed. This practice allows the digestive enzymes in the mouth to do their work properly and, in addition, it gives the stomach time to prepare for the arrival of the masticated food. It is important that one eats at a moderate speed.
One should eat and drink with discipline and regularity for eating is a meditation. Eating in this way will nourish your body mind and consciousness and will also enhance longevity.”
