COURSE OF NUTRITION AND FEEDING
LIQUIDS .
The water is an indispensable food in the feeding: the body needs it he/she will be able to carry out all its functions and to stay fresh. Around 60 organism% it is composed of water; this percentage is smaller when adult is the quantity of accumulated fat; because the cells that contain the adipose tissue hardly contain water.
In the healthy organism, the consumption and the elimination of water they are balanced this it remains where it should be and almost everything happens it in automatic form. The hunger and the thirst regulates the ingestion of waters and minerals, and the kidneys regulate its elimination. The complex physiochemical mechanisms that sustain the life make possible that the water and the minerals dissolved in this they are in fact retained where the body needs them: for example, most of the sodium remains outside of the cells, most of the potassium, inside them
THE FEEDING AND THE WATER.
The water is not ingested alone when drinking but also when eating, because almost all the allowances contain it in abundance: the fruits and vegetables contain 80% of water; the rice and the boiled pastas, 70%, and the bread around 35%. Therefore, he/she doesn't generally need to drink but of 6 to 8 glasses of water per day (that is to say, around about two liters).
It is strange that the organism suffers for lack of water. The athletes and who make vigorous exercises they lose sodium, potassium and chlorine, besides water but in general the normal feeding allows to restore them; also, the kidneys have capacity to regulate the levels of waters, sodium and potassium in the urine when the ingestion of this elements suffers alterations or when one sweats intensely. He/she doesn't need to take pills of salt, neither drinks, powders or special allowances for sportsmen; in fact, even when this products are sweet and they turn off the thirst, they spread to belong to the person he/she drinks less water that which is but harmful that beneficial. If a person drinks too much water, she doesn't have because to be disturbed: the kidneys took charge of eliminating the excess; also, the water doesn't put on weight in fact since it doesn't contain calories. On the other hand, the sodas, the alcoholic drinks, the lemonades, the juices and those malted are very rich in calories.
Aveces the diets alter the balance of the corporal liquids; the drastic diets to lose weight, for example deceive when making that the body loses water, but alone for short time. The alcoholic drinks, the coffee, the you and some sodas made with the help of line produce certain diuretic effect that, in extreme cases, it can cause dehydration when affecting to the system cardiocirculatorio and to hinder the elimination of the excessive corporal heat, the serious dehydration happens when the body loses but of 2% of its weight; he/she makes him to increase the corporal temperature and the heart frequency and it causes fatigue, apathy and wrong physical acting.
SPECIAL CASES.
Although the body usually balances its content of water, in certain cases it is necessary to help him increasing the ingestion of liquids deliberately; if one has high fever it is necessary to drink them in abundance, and if you travels to some very hot region or if the climate becomes warm and dry, the body needed time to adapt and quarry a lot of water when perspiring; under these conditions, during one week he/she will be necessary to drink it in great quantity.
For I finish, there is a good advice here for those who accustom to make vigorous exercises. It is convenient to be weighed (of preference without clothes) before and after making them. If he/she gets lost but of 2% of the corporal weight, it will be necessary to drink but he/she dilutes before making the exercises and during their course to compensate the lost one caused by the evaporation and the perspiration. He/she will suit to have to the hand it also dilutes cold and to drink it regularly although he/she doesn't sit down thirst; with the time, this will memorize in the such way that he/she will become something that one makes without thinking.
