PROBLEM SOLVING OF NUTRITION ON HEALTH
What are the problems ?
1.What are the main and essential composition of nutrition on health?
2.What are the effects of nutrition on health promotion, prevention and treatment?
3.What kind and amount of foods that promote, prevent and treat or cure the diseases as health problems?
The answer for those problems as problem solving will be describe as follows :
1.What are the main and essential composition of nutrition on health?
Let us translate it into 3 sub-problems:
· What is the aim of nutrition?
· What are the main compositions of nutrition?
· What is the essential nutrient?
The aim of the science of nutrition is the determination of the kinds and amounts of foods that promote health and well-being. This includes not only the problems of under-nutrition but those of over-nutrition, taste, and availability. How ever, certain substances are essential constituents of any diet.
Essential human requirements usually not considered to be nutrients: oxygen, water and sunlight [for synthesis of vitamin D].
There are 6 main or major components of nutrition: protein, fat, carbohydrate, vitamins, minerals and water.
The carbohydrate, fat and protein yield energy provide for growth, and maintain tissue subjected to wear and tear.
Vitamin, mineral and water although they do not yield energy, are essential parts of the chemical mechanism for the utilization of energy and for the synthesis of various necessary metabolites such as hormones and enzymes.
The minerals are also incorporated into the structure of the tissue and, in solution, play an important role in acid-base equilibrium.
The energy aspect of the nutrition or diet.
The energy for physiologic processes is provided by the metabolism of carbohydrate, fat and protein. The daily requirement or daily caloric need is the sum of the basal metabolic rate, specific dynamic action, growth, exercise or work, and unused portion.
Distribution of the calories in the nutrition or diet:
In well balanced diet,
10-15 % of the total is usually derived from protein, 55-70 % from carbohydrate, and 20-30 % from fat. These proportion vary under different physiologic conditions, works, or in various environmental temperature. For example the need for calories is increased by the need to retain a constant body temperature in winter or in extreme cold condition, the caloric intake of the diet must therefore increase and this requirement is usually met by increasing the fat content of the diet.
What is the essential nutrient?
An essential nutrient is a nutrient required for normal body functioning that either cannot be synthesized by the body at all, or cannot be synthesized in amounts adequate for good health and thus must be obtained from a dietary source.
Some categories of essential nutrients include essential amino acids, essential fatty acids, vitamins, and dietary minerals.
Essential amino acid or indispensable amino acid is an amino acid that cannot be synthesized by organism, and therefore must be supplied in the diet. Eight amino acids are generally regarded as essential for humans:
Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Additionally , cysteine [or sulphur-containing amino acids], tyrosine, histidine and arginine are required by infants and growing children.
The nonessential amino acids are: Alanine, asparagine, aspartate, cysteine, glutamate, glutamine, glycine, proline, serine, tyrosine, arginine, histidine.
Essential fatty acids [EFAs] are fatty acids that cannot be constructed within an organism from other components by any known chemical pathways, and therefore must be obtained from the diet. The essential fatty acids start with the short-chain polyunsaturated fatty acids [SC-PUFA]. There are two families of EFAs: omega-3 [w-3, or n-3] and omega-6 [w-6, or n-6].
Omega-3 fatty acids such as alpha-linolenic acid or ALA [18:3].
Omega-6 fatty acids such as linoleic acid or LA [18:2]
The other main components of fat which not essential are saturated fat, trans fat and cholesterol. Cholesterol consists of high density lipoprotein cholesterol [HDL-C] or good cholesterol and low density lipoprotein cholesterol [LDL-C] or bad cholesterol.
The essential vitamins are: Vitamin A [retinol], B1 [Thiamine], B2 [Riboflavin], B3 [Niacin, vitamin P], B5 [Pantothenic acid], B6 [Pyridoxine], B7 [Biotin, vitamin H], B9 [Folate, folic acid, vitamin M],B12 [Cobalamin], Cholin [vitamin Bp], C[ascorbic acid], D [ergocalciferol or cholecalciferol], E [tocopherol] and K [naphthoquinoids].
The essential minerals are: Calcium [Ca], Chloride [Cl], Cobalt [Co], Copper [Cu], Iodine [I], Iron [Fe], magnesium [Mg], Manganese [Mn], Molybdenum [Mo], Nickel [Ni], Phosphorus [P], Potassium [K], Selenium [Se], Sodium [Na], Sulfur [S], and Zinc [Zn].
The body’s requirements vary widely. At one extreme a 70 kg human contains 1.0 kg of Calcium but only 3 mg of Cobalt.

THE MAIN AND ESSENTIAL NUTRITIVE VALUE OF FOODS
THE MAIN AND ESSENTIAL NUTRITIVE VALUE OF FOODS AS INPUTS FOR BETTER HEALTH STATUS
The characteristics of life that come to mind are warmth and movement If the human is still and cold it is assumed to be dead.
By taking in food and oxidizing it the human obtain energy which is used to produce heat and movement. The energy is obtain by oxidation of body constituents by a process known as catabolism. The energy obtained by catabolic processes may also be used for anabolic or synthetic processes such as are necessary for growth. Since both processes occur side by side it is convenient to use the word metabolism when referring to the total chemical changes occurring in the cell or in the body.
Living organisms posses two properties under the heading of adaptation and homoeostasis. Simple forms of life can survive over a wide range of temperature and can adapt themselves to change in the environment and to the foodstuffs available.
Although the regulation of the internal environment reaches its highest development in man he has gone still further be attempting to control his external environment. At first then involved the wearing of clothing, the building of shelters and houses, and the use of artificial heating, lighting, ventilation, transportation, manufacturing, communication and information technologies.
The trend in modern medicine and surgery, however, is to study the living patient more and more intensely in order to understand not only the symptoms but the way in which normal physiological and biological processes have been broken down, for diseases coming increasingly to be thought of as a disordered physiology in which the compensatory mechanisms have been overstrained or are inadequate
The cure and prevention of many disease is due to the rapid advances in our knowledge of bacteriology and immunology. But less advances in degenerative diseases such as heart disease, cancer, metabolic disorders and nervous system diseases
The source of all energy required by the body for life such as carrying out muscular activity, for respiration, for beating of the heart, for digestion , for thinking ,is the food.
What are the most need value of substances for life?
Let’s see the mathematic of life:
1.HUMAN LIFE+WATER+NUTRITION+PAT [Property and treasure]-OXYGEN = DEAD IN LESS THAN ONE HOUR.
2.HUMAN LIFE+OXYGEN+NUTRITION+PAT-WATER=DEAD IN A FEW DAYS.
3.HUMAN LIFE+OXYGEN+WATER+PAT-NUTRITION= DEAD IN A FEW WEEKS.
4.HUMAN LIFE+OXYGEN+WATER+NUTRITION-PAT= LIFE, SIMPLE AND SUSTAINING
These simple mathematic formulas for life has the result the most valuable need for life is oxygen, the second is water, the third is nutrition and the fourth is PAT [property and treasure].
Good nutrition is essential for good health. Nutrition directly affects growth, development, reproduction, well being and the mental condition of the individual. Health depends upon nutrition more than other substances.
