Beef provides a significant portion of human dietary selenium (Se), and it is possible that modest portions of beef produced in areas with high-Se soil and forage could provide the entire Recommended Dietary Allowance (RDA) for Se. The present study has addressed the environmental conditions that resulted in the production of high-Se beef. One hundred and thirty-eight cull cows were obtained fr...

Following the comprehensive systematic review of domestic and overseas scientific evidence, the "Dietary Reference Intakes for Japanese, 2005 (DRI-J)" was published in April, 2005. The DRIs-J were prepared for health individuals and groups and designed to present a reference for intake values of energy and 34 nutrients to maintain and promote health and to prevent lifestyle-related diseases and...

BACKGROUND Multiple micronutrient deficiencies are common among women in low-income countries and may adversely affect pregnancy outcomes. OBJECTIVE To conduct a meta-analysis of the effects on stillbirths and on early and late neonatal mortality of supplementation during pregnancy with multiple micronutrients compared with iron-folic acid in recent randomized, controlled trials. METHODS Tw...

The nutritional value of a high-carbohydrate diet was evaluated. Seven male marathon runners kept a food record diary for the three days preceeding two endurance races. They were instructed in how to compose a diet which contained about 9 g carbohydrate day-1 kg body weight-1. Sixty three per cent of the subjects' total energy intake was derived from carbohydrates. The dietary intake of vitamin...

Determinants of the recommended dietary allowance (RDA) for vitamin C include the relationship between vitamin C dose and steady-state plasma concentration, bioavailability, urinary excretion, cell concentration, and potential adverse effects. Because current data are inadequate, an in-hospital depletion-repletion study was conducted. Seven healthy volunteers were hospitalized for 4-6 months an...

Many adolescents are at an increased risk for anemia due to their rapid growth and increasing muscle mass. However, adolescent females with heavy menstrual bleeding are at an even greater risk for anemia. Heavy menstruation in adolescent females not only has negative effects on health-related quality of life and school attendance, but also has major health implications such as iron deficiency a...

To assess the association between dietary magnesium intake and hyperuricemia in United States (US) adults, we extracted 26,796 US adults aged 20-85 years from the National Health and Nutrition Examination Survey (NHANES) in 2001-2014. All dietary intake was measured through 24 h dietary recall method. Multivariable logistic regression analysis was performed to investigate the association betwee...

The aim of this study was to evaluate the effect of a higher protein intake on lean body mass (LBM) gain in postmenopausal women practicing resistance exercise and compare it to the Recommended Dietary Allowance (RDA) recommendation. Twenty-three postmenopausal women (63.2 ± 7.8 years) were randomized into two groups. The group with higher protein intake (n = 11) (HP) received a dietary plan wi...

A large survey by the Ministry of Agriculture, Fisheries and Food of people aged 15 to 25 showed that the women, and especially the participants "on a diet" or "watching their weight," generally had iron intakes well below the recommended daily allowance. Reduced iron intake appeared to result from diets of reduced iron concentration as well as from energy restriction. Further research is neede...
