The requirement for vitamin E is closely related to the dietary intake of polyunsaturated fatty acids (PUFA). By the protective mechanism to prevent PUFA from being peroxidized, vitamin E is metabolically consumed. In addition, PUFA impair the intestinal absorption of vitamin E. Therefore PUFA generate an additional vitamin E requirement ...

1. Three experiments were carried out with light strain laying hens to evaluate the effects of relatively high doses of dietary vitamin E (125 mg/kg food) or ethoxyquin (EQ) (250 mg/kg food) on their laying performance. The control diet contained 5 and 125 mg/kg vitamin E and EQ, respectively. The ...

Cataract is one of the major causes of age-dependent visual impairment and blindness. The geographic distribution of cataract is known to be associated with the intensity and duration of sunlight--especially of the ultraviolet frequency--at particular places. Exposure of animals and humans to oxygen has also been known to result in ...

Recent studies indicate that nearly one in five older adults has xerostomia (dry mouth). Salivary gland dysfunction and/or inadequate saliva increases the difficulty of these older adults in obtaining proper nutrition. Problems in lubricating, masticating, tolerating, tasting, and swallowing food contribute notably to the complex physiological and psychological manifestations of ...

Data from the Second National Health and Nutrition Examination Survey were analyzed to determine food and nutrient intake differences between current smokers (also categorized as light, moderate, and heavy smokers) and non-smokers. Smokers in several age-race-sex categories have lower intakes of vitamin C, folate, fiber, and vitamin A than non-smokers, ...

Different sources of dietary fibre (cellulose, pectin, Isabgol, cabbage and guava) were fed to weaning rats for 5 weeks to study their effect on serum vitamins. Both the plant foods (cabbage and guava) were analysed for dietary fibre. Guava was found to be a good source of dietary fibre constituting ...

Anticoagulation instability due to a change in intake of vitamin K after dietary modification was observed in 2 patients on long-term oral anticoagulants. One patient developed diffuse bruises treated conservatively with fresh frozen plasma transfusion and the other had a thrombosed aortic prosthesis which required emergency operation. To prevent such ...

Previous studies suggest that Parkinson's disease (PD) is negatively associated with early-life intake of vitamin E-rich foods and positively associated with rural experience. Using a new survey design, we attempted to confirm and extend these results. We gave a telephone questionnaire to 106 patients with PD and to their spouses ...

Significantly elevated Thrombo-test values after natto intake were observed in patients undergoing anticoagulant therapy after valve replacement operations. Corroborative tests with humans and rabbits to check the observations showed natto to be strongly antagonistic to warfarin. The author suspected that Bacillus natto contained in natto might produce a large amount ...

Further clarification of the bioavailability of dietary vitamin B6 requires better analytical data concerning the forms of vitamin B6 in foods as well as the overall composition of foods. The application of radioisotopic and stable-isotopic studies such as those described will provide useful information concerning the inherent bioavailability of the ...

Preparing vegetables with heat the contents of their constituents will change to a various extent. Particularly the water-soluble and the heat-sensitive vitamins are affected. At an early stage the vitamin C losses were investigated, because of vitamin C's indicating function for oxidation and leaching-out processes (1, 2, 7, 11-13, 15, ...

Over the millennia various hominoids and hominids have subsisted on very different dietaries, depending on climate, hunting proficiency, food-processing technology, and available foods. The Australopithecines were not browsers and fruit-eaters with very high intakes of vitamin C; rather they were scavengers of kills made by other animals. The hominids who ...

In this study the conventional autoclaving technique was modified by incubating the food overnight prior to autoclaving. This treatment resulted in a markedly improved consistency of the food pellets, comparable with that of untreated food. The modified autoclaved food did not adhere to the walls of feeders or clog the ...

The dietary intake and biochemical status of vitamin B-6 in 476 apparently healthy Dutch elderly people (aged 65-79 y), who were not using drugs known to affect vitamin B-6 metabolism, were evaluated. Intake of vitamin B-6 per gram protein was related to biochemical data, namely plasma pyridoxal 5'-phosphate (PLP) and ...

The administration of warfarin requires careful attention. The concurrent intake of drugs can either enhance or compete with its anticoagulant effect. Less frequently encountered are the effects from vitamin K added to food, intake of foods with naturally occurring high levels of vitamin K and diets deficient in vitamin K. ...

Exposure to sunlight initiates the formation of vitamin D3 in skin as the UV B radiation in the solar spectrum causes the photoconversion of 7-dehydrocholesterol to previtamin D3. A heat-induced isomerization then converts previtamin D3 to vitamin D3 over a period of days. A number of irradiation products of vitamin ...
