Ayurveda is one of the great gifts of the sages of ancient India. It is one of the oldest scientific medicinal systems in the world. It is also known as Fifth Veda or Pancham Veda. It just teaches us how to maintain and protect health, how to cure diseases and how to achieve longetivity.

Here are general tips for balance:
1.  In Ayurveda there are six tastes or rasas - sweet, sour, salty, bitter, pungent and astringent. Generally all meals should include at least a small amount of each taste.
2.  Eat in a settled environment when you are calm and relaxed.
3.  Always sit down to eat.
4.  Be silent while chewing.
5.  Minimise ice-cold food and drink.
6.  It is best to consume fruit (or fruit juice) separately from other foods.
7.  Enjoy a light nourishing breakfast and make lunch your largest meal of the day, with a smaller meal in the evening (3 - 4 hours before bed).
8.  Eat only when you are hungry and leave about 25% of your stomach empty as this will aid digestion.
9.  Wait approximately 4 hours between meals to allow adequate time to digest. This might be less between small meals and more between big meals.
10. Water should be avoided at least 15 minutes before food. The quantity of water after food should be small. Let it be drunk often.
