Sri Lanka is a country which enjoyed a great food culture. Our ancestorsalways consumed natural foods. Greens (herbals) of medicinal value, the localvegetables and cereals were an essential component in their daily meal. Theydid use and adopted various ingredients to stimulate their taste buds and retainthe nutritional value. Using local methods like adding tamarind, goraka, sera,cinnamon, curry leaves etc. Seven curries (Hath maluwa), Mixed green (KalavanMalluma), Milk rice with Green gram (Munata Kiribath), Sambar, Biriyani rice,are some of their mixed preparations. Their culinary art was different from today.They had various other combinations of which in some still exist in the ruralareas. They seldom cooked one kind of food. They used jack seeds for manycombinations. E.g. Jack seeds and Kehel Muwa(the remainder of the banana
flower), Jack seeds and Sarana or any similar green, Dhal and Spinach or anysimilar green, Bread fruit and a green like spinach or Sarana. The open economygradually brought in different kinds of food to Sri Lanka and change rapidly thefood consumption pattern specially among the urban population. This included
junk food, instant food and processed food. People always tend to rush in forthe latest now. So with the food too. But it is more wise to revert back to healthyculinary art and form a healthy food culture so that the new generation will havea taste for healthy food. We must eat to live and not live to eat.
When preparing food there are two main factors to be considered. They are,to prepare food to maintain the nutritional value and also
to improve the nutritional value .

(a) Food should be taken when the body demands, because the system isready with digestive juices, and at least 3 hours after the next meal. To getthe maximum from the nutrients, system should be trained to a regularpattern.
(b) Natural fresh food as well as the preparations and substances added shouldenhance the nutrient value. It should be palatable, tasty, easier to swallowand digest.
(c) Combination of food should improve the quality of nutrients and also beaware of unhealthy combinations. Health Education Beaureau promotestaking 5 kinds of vegetables a day. If we combine food we should knowwhich types we should combine when preparing, for taste, flavours andnutritional value.

(d) Food habits play an important role in the nutrition of an individual. Selection of food, quantity, quality, place, condition should be included into a pattern and asystem of food habits for it will affect adversely to the nutritional value. Food servedshould be sufficient to the individual's needs. Serving too much and throwing awayis not a good habit.
(e) Food should be selected to suit the time, age, period, condition of theindividuals. False beliefs, false sense of status, should not be the criterionwhen selecting food. But strictly consider the nutrient value of the food tosuit the condition of individuals.
(f) The quantity and the quality of the food consumed is another important factor.Having a bellyful of food disturbs the proper function of digestion. Thequantity, quality should suit the age, sex condition of the individual. Thedeciding factor of the quantity of food consumed should be the condition of the hunger. Similarly the condition of the person, specially when a person issick if the same quality and quantity is consumed, it will disturb the absorptionof nutrients. Easily digested foods are best suited for the sick. Other conditionslike pregnancy, lactation, old age too should be considered to maintainnutritional standard. A mother needs more food and an elderly person shouldtake easily digested food.
