Unbalanced nutrition

Astr ali radix" (AR) [83] is an important traditional Chinese herbal medicine widely used in China and Japan. It is used to improve naturally weak constitutions, as an invigorating drug to improve the immune response, often for the elderly, and to coxmter unbalanced nutrition in China. The immunostimulant effect of polysaccharides, isolated from A. membranaceus, has been proved so many authors recommend that this plant may be used in immunotherapy. It is chiefly used as a decoction. 

Polyhydroxyalkanoates (PHAs) are polyesters formed by many prokaryotic micro-organisms-when unbalanced nutritional conditions are chosen for die (Hoducing cells Up to more than 90% of the cell dry weight can be accounted for as polymer. Besides the homopolyester poly-R-3-hydroxybutanoate, consisting of 3-hydroxybutanoate (3HB) only, two main types of copolyesters can be formed by different microorganisms. The first type of PHAs always contains C3 units in the polymer backbone, but the... 

Lack or deficiency of a V., as a result of unbalanced nutrition, leads to charaeteristic metabolic disturbances. Complete absenee of a V. leads to avitaminosis, with typical clinical symptoms. Relative deficiency of a V. causes hypovitaminosis. Such conditions are reversible by administration of the appropriate V. Excessive intake of certain V, e.g. V.A or V.D, can lead to hypervitaminosis. Formerly, V. were named after the diseases they cured, e.g. antiscorbutic V., antirachitic V, antiberiberi factor. Not all V., however, have such a pronounced specificity, and the clinical pictures of many avitaminoses and hypovitaminoses are complex and variable. A nomenclature based on letters of the alphabet was developed simultaneously the designations A, B, C, D and E were applied in the historical order of discovery. Subscripts were applied as more refined chemical analysis revealed that the originally isolated substances were in fact complex mixtures. This was especially true for the B vitamins. Partly because of confusion over the B complex , trivial names which give an indication of the chemical structure of the V. (e.g. pyridoxine or pyiidoxol for V.B() are now preferred. 

Filling the Requirement of Vitamins. Deficiency diseases appear very rarely under adequate nutritional situations. Such diseases are the consequence of unbalanced nutrition. Hypovitaminoses are actually clinically more significant than the avitami-... 

Nutritional problem is the key issue along with food security in Bangladesh today. A small percentage of the people have access to nutritious food, whilst the majority is forced to survive on subsistence diets that are unbalanced and devoid of essential food ingredients (MoA-UNPD 2000). Generally, landless and marginal farmers are at... 

The NPN content has been demonstrated to range from 15 to 37% at harvest (6, 7). The only published report of the composition showed the NPN fraction to be nutritionally unbalanced, containing mostly amino acids and amides (6). The major components were asparagine, 61% aspartic acid, 11% glutamic acid, 4% serine,... 

Nutritional factors such as a poor or an unbalanced diet may influence the intake and probably also the biotransformation of food contaminants. Ethnic differences due to variations in, e.g., dietary habits have also been reported (KEMI 2003). 

Testing as a whole This may characterize the toxicity profile of the mixture and eventually verify the (presumed) safety or hazard from exposure to mixmre. One problem may be that incorporation of the test material in the diet at a sufficiently high dose may result in an unbalanced diet and nutritional deficiencies. Another problem is that most mixtures may change in chemical composition over time. 

A nutritional deficit is the result of having less than the adequate amount of nutrients because of an unbalanced diet, surgery, trauma, malignancy, and other conditions that breakdown (catabolize) the body. 

Our supermarkets today provide an abundance in food choices, yet most Americans do not follow the research based advice on good nutrition summarized in The Dietary Guidelines for Americans. Instead, people plan and select a diet of traditional foods that they believe will meet their needs. In the best of cases, this can result in a balanced, healthful diet that makes a positive contribution to the quality of life. In the worst of cases, it can result in over-consumption of some nutrients, under-consumption of other nutrients, and a generally unbalanced diet that results in a general or specific decrement in health. Our goal must be to consume the variety of foods necessary to obtain in the appropriate amounts (i.e., the levels associated with the lowest prevalence of disease and longest life), all the nutrients and protective compounds found in food (1). 

Concentrations of various carboxylic acids in human body fluids reflect some of the major metabolic processes of the body. These metabolites apparently originate from lipid and amino acid metabolism the major metabolic defects are frequently associated with unbalanced concentrations of these acidic substances. One of the most widely occurring conditions of this kind is ketoacidosis in diabetic disease high concentrations of the so-called ketone bodies (3-hydroxybutyric acids, acetoacetic acid and others) are the traditional hallmarks of ketoacidosis. Many additional acidurias were discovered (particularly during the last 15 years) in major part due to the availability of GC and GC/MS techniques. Acidurias are among the serious medical conditions that are usually a result of genetic aberration (enzyme deficiencies), but environmental factors or nutritional deficiency could occasionally be involved. These conditions are characterized by either (a) drastically enhanced excretion of normal metabolic intermediates, or (b) excretion of unusual metabolites that are produced from the accumulated intermediates via alternate biochemical pathways. Many acidemic conditions have now been documented in the literature, and the role of GC in such medical discoveries has been adequately stressed in the recent reviews of Jellum [15] and Tanaka and Hine [373]. 

Usually, joy is not present because we haven t allowed it to be. We block it chemically, with unbalanced biochemicals in our brain, with poor nutrition that depletes our bodies, or sleep patterns that disrupt our relationship to nature and our own cycles. We block it with our thoughts, when we strive to control the uncontrollable, to grasp after happiness, to push away love and connection, to blind ourselves to internal and external reality. We block it with our hearts, too, when we close down in fear or resentment or confusion. You cannot receive an object when your hand is clenched. You cannot receive food when your jaws are clenched. You cannot receive joy when your mind is clenched. And you cannot receive love when your heart is clenched. 

One of the most serious nutritional problems in the developing countries of the world is a group of disorders associated with inadequate or unbalanced intakes of protein and energy.
