OBJECTIVE: We measured the serum levels of four trace elements (Cu, Zn, Mn, Pb) and Mg in surgical patients receiving total parenteral nutrition (TPN). The clinical implications and the results are discussed.METHODS: Two groups of patients were studied: the first group (n = 40) was our study group and the second (n = 40) was the control group. Four measurements of each trace element (TE) in blood...
OBJECTIVE: Epidemiologic studies have suggested that dietary intake and plasma concentrations of antioxidants have an inverse relation with coronary heart disease. To test whether fat-soluble antioxidants can play a role against the occurrence of myocardial infarction (MI), we measured plasma levels of retinol, tocopherols, and individual carotenoids in MI patients.METHODS: A case-control and follow-up...
OBJECTIVES: Hyperhomocysteinemia is regarded as a public health problem of increasing importance likely to contribute to vascular disorders and premature mortality. Folate, cobalamin, pyridoxine, and riboflavin dietary deficiencies are currently regarded as causative factors. However, several investigations have indicated that the theory of vitamin B deprivation provides only a partial explanation...
In many Sub-Saharan African populations, in particular urban dwellers, there have been marked rises in the prevalences of obesity in women, hypertension, diabetes, and cerebral vascular disease. Yet there have been only slight rises in coronary heart disease. To learn more of the roles of the various influencing factors in the puzzling situations described, some aspects of the past and present occurrences...
The flavonols belong to a large group of compounds called flavonoids, which are diverse in their chemical structure and characteristics. Fruits, vegetables, and beverages such as tea and red wine are major sources of flavonols in the human diet. The daily consumption of flavonols is difficult to estimate because values depend on accurate assessment of feeding habits and flavonol content in foods....
OBJECTIVES: Although it is well known that leptin reflects body fat content in adults, the regulation of leptin levels during childhood malnutrition is poorly understood. Insulin-like growth factor I (IGF-I) and the IGF-binding proteins (IGFBPs) may play important roles in the regulation of body composition. We investigated the relation between leptin, IGF-I, and IGFBPs in children with protein-energy...
OBJECTIVES: Vitamin D plays a critically important role in the development, growth, and mineralization of the skeleton during its formative years, and performs an equally essential role in maintaining a healthy mineralized skeleton for adults of all ages. We evaluated the vitamin D status and risk factors for vitamin D deficiency in healthy breast-fed newborns and their nursing mothers.METHODS: Serum...
Nutritional status, iron-deficiency-related biochemical indices, and immunologic patterns of female Judo athletes and control subjects were evaluated. The subjects' 3-d food records showed that 41.0 kcal/kg of energy was consumed daily and the contributions of protein, fat, and carbohydrate to total energy intake were 12.5%, 29.2%, and 58.3%, respectively. The reported vitamin intakes of athletic...
OBJECTIVE: The time of day of meal ingestion, the number of people present at the meal, the subjective state of hunger, and the estimated before-meal contents in the stomach have been established as influences on the amount eaten in a meal and these influences have been shown to be heritable. Because these factors intercorrelate, the calculated heritabilities for some of these variables might result...
Objective: We investigated the influence of different edible oils high in oleic acid but with different unsaponifiable fractions on the fatty acid composition and lipid peroxidation in plasma and low-density lipoprotein (LDL) in rabbits.Methods: Thirty-two rabbits were randomly assigned to four groups of eight animals. For 8 wk each group was fed a semisynthetic isoenergetic diet that differed by...
OBJECTIVES: We investigated the clinical usefulness of soluble dietary fiber (SDF) for the treatment of diarrhea during enteral nutrition in elderly patients.METHODS: This study included 10 men and 10 women (mean age +/- standard deviation: 79.3 +/- 5.1 y) who had diarrhea during long-term nutrition management. When administering SDF, the initial dose was 7 g and thereafter gradually increased at...
Under normal conditions, the homeostasis of energy intake is maintained in the hypothalamus by 1) transducing metabolic and sensorial inputs arising from the periphery into neuronal response, 2) integrating the information originating from different tissues, and 3) triggering the appropriate feeding responses. If cancer anorexia is considered a disruption of the physiologic mechanisms controlling...
