Physiology of Nutrition - the science that develops. She is constantly enriched with new facts and research methods that are based on the achievements of related sciences - chemistry, biochemistry, physics, molecular biology, general physiology and medicine. Therefore, one of the challenges facing the engineer, is a creative nabisco bowling use for all new struggle with outdated traditions in catering, with standard approaches to the selection of the range of products and production of finished products without matching their needs certain part of the population served . However, it should critically evaluate the materials published on nutrition, and especially not scientifically grounded recommendations, "fashionable" theory, which in this area often cause irreparable harm.
In the workplace and everyday life of people with possible contact hazards. nabisco bowling These include toxic chemicals used in industry, solvents, acids, alkalis, magnetic fields, radiation optical lasers, ionizing radiation and others.
In these circumstances, the importance of biomedical events, including important element of preventive nutrition. Preventive nutrition - a special food for the workers of hazardous nabisco bowling industries. The basis of this food is good food, but built on the basis of exchange of harmful substances in the human body and health of the individual foods that protect nabisco bowling the body from the negative effects of chemical compounds and physical factors. Preventive nutrition is a mandatory component of the system and preventive health measures aimed at limiting the negative impact on the body of harmful factors nabisco bowling of production environment.
Based on extensive experimental nabisco bowling research nabisco bowling and summarize data from the literature on the toxic effects of a large number of industrial poisons, their mechanism of action, biotransformation poisons nabisco bowling A. O.Pokrovskym formulated the basic principles of preventive nutrition:
- To increase the overall resistance, its adaptation reserves; nabisco bowling its efficiency, improve health, reduce overall morbidity and professional, contribute to the continuation of active life, poperedzhuvannyu premature aging; act by means of individual nutrients on the state organs nabisco bowling and systems that are most affected;
Environment, including production, always affects the human body. Chemical, physical and biological factors directly or indirectly influence the condition and stability of internal environment, the functioning of organs nabisco bowling and systems at different levels, nabisco bowling ie homeostasis nabisco bowling (dynamic nabisco bowling relative constant internal environment, sustainability basic physiological functions).
Chemicals as factors of production or the environment, nabisco bowling entering the body, violate the "chemical purity" internal environment and face the homeostatic mechanisms of detoxification as the first line of defense against the body. Detoxification is in biological membranes of cells. The effective detoxification possible for their safety. Violation of intact biological membranes leads to a breakthrough nabisco bowling in the intracellular environment of xenobiotics and identify their toxic effects. Chemical agents interfere nabisco bowling with the molecular mechanisms of biological, including biochemical systems (receptor biological membranes, enzymes, antibodies, etc.) interfere with the normal course of metabolism, causing nabisco bowling a shift homeostasis at the cellular and tissue levels (Fig. 1). These phenomena are considered primary dyshomeostatychnymy disorders. The degree of disorders of homeostasis depends on the intensity and duration of exposure of chemical factors. If a critical level changes in the primary pathological process may be involved related biological systems. Then there are more profound, widespread and significant imbalance in the functioning of systems (secondary disturbances of homeostasis), which can lead to the formation of "vicious circles pathological", which in turn support the stability of the pathological condition.
There are many proposals for the definition of "quality of food." In GOST 15467-79, the term "quality" is the sum of product nabisco bowling properties that determine its ability to meet the specific needs according to their purpose.
In food hygiene, food quality - a set of properties that determine the suitability of products for nutrition nabisco bowling (organoleptic and physical-chemical properties, food and biological value).
You also need to have safe food in sanitary and epidemiological aspects, ie, with no signs of rot, mold, fermentation, oxidation, zhirklosti. A reasonable definition of quality food is provided in "Medical Biology Requirements and Quality standards sanytarnыh prodovolstvennoho raw materials and pyschevыh food (
