Food forms the foundation of Life. Healthy food builds healthy tissues of the body. The fresh the food is, the better it is. Stored food and food with decaying matter would have its impact on the tissues. If one is accustomed to unclean food, even from childhood may not see any immediate danger of such habit. But one should remember that the germs of most terrible diseases are contained in impure food. This knowledge enables avoidance of stored food and drinks and adaptation to fresh foods and drinks. Any postponement to such adaptation is permissible only in a limited way. Eventually, ignorant sowing will yield its harvest of incurable sicknesses.
The modern life promotes mostly stored food, stored fruit juices and aerated drinks. It is no wonder that these inferior foods and drinks contributed through time to upsurge our sicknesses. People have neither time nor inclination to ensure that fresh food and fresh drinks are supplied to body. They are just unmindful of this dimension. Even the so called mineral waters stored in plastic bottles over days are questionable of their healthy condition.
Men would not like to fall into sickness and much less into chronic and incurable sicknesses. The first and fundamental duty to prevent manifesting of sicknesses is to ensure healthy, clean and fresh intake of food in rhythmic intervals. Not much can be done when ignorance already causes the needed damage. People are afraid of dead cells of Cancer. Instead, they should be afraid of food containing dead matter.
A clean life is but the basic foundation upon which activity can be built.
Nourishing the subtle body as also the vital body, is best done through vegetable diet. Freshly cooked vegetables are best suited for human intestines for nourishment. Raw vegetables in so far as they are suitable to intestines can also be taken. Eating raw vegetables and cooked vegetables at the same time is not considered wise. The digestive system should be fed to uniform work but not zigzag work through dishes which require different degree of digestion.
The ancients knew the order of eating. They recommend a sweet liquid preparation to start with, followed by liquid food such as rice mixed with vegetable soups. This further followed by vegetables and lentils to be concluded with yogurt and again a sweet preparation. The order of eating recommends intake of easily digestible fluids followed by less easily digestible substances and concluded by, again dishes that improve the flora of the digestive system. The beginning and the conclusion is with freshly made sweet preparations. Such is the order given in Vishnu Purana, the Mother of all Puranas.
Men should know their digestive systems and develop a programme accordingly to avoid indigestion and constipation which would form eventually a platform for sicknesses.
