Ancient principles for a healthy diet

From the Charaka Samhita, which is thought to be the oldest of the treatises of Ayurvedic medicine (1000BCE):

1. Food needs to be hot (usually cooked).

2. Food needs to be tasty and easy to digest.

3. Food needs to be eaten in the proper amounts, not too much or too little.

4. Foods needs to be eaten on an empty stomach, after your last meal has been digested, and not before.

5. Foods need to work together and not contradict one another in their actions.

6. Foods need to be eaten in pleasant surroundings with the proper equipment for their enjoyment.

7. Eating should not be rushed.

8. Eating should not be a horrendously drawn out affair either.

9. It is best to focus on your food while eating.

10. Only eat food which is nourishing to your particular constitution and which suits your mental and emotional temperament.
