The Johns Hopkins University Evidence-based Practice Center (EPC) reviewed and synthesized the published literature on four Key Questions: 1. What is the efficacy of multivitamin/mineral supplement use in the prevention of chronic disease for the general adult population? 2. What is the safety of multivitamin/mineral supplementation in the general population of adults and children? 3. What is t...
Concentrations of Al, Cd, Cu, Ni, and Pb in Laurus nobilis L. were examined for assessment of the impact of heavy metal exposure during winter periods, since these metals have the highest toxic potential. In this study, leaf (washed and unwashed), bark and branch samples of L. nobilis and soil samples were collected from 13 different localities, belonged to three stations. In conjunction with a...
In addition to determining the amounts of isolated nutrients required for physiological function and homeostatic control, setting Recommended Di etary Allowances requires a consideration of nutrient bioavailability from foods in common diets. Bioavail ability algorithms, or mathematical models to estimate nutrient bioavailability from different diets, have great appeal to help establish recomme...
Drinking water, a fluid primarily for human hydration, is also a source of mineral nutrients. Groundwater, a drinking water source for more than 70% of inhabitants living in Asian deltas, has received much attention because of its naturally occurring arsenic, but the linkage of arsenic toxicity with other water constituents has not been studied. In addition, although nutrients are generally pro...
BACKGROUND There continues to be considerable debate about the role of acid vs. basic components of the diet on the long-term status of bone mineral density. AIM In a set of two analyses, we examined the effect of components in the diet thought to have basic effects (magnesium, potassium, fruit, vegetables) and acid effects (protein) on bone mineral density in an elderly cohort. METHODS Bon...
Enhanced efficiency nitrogen (N) fertilizers (EEFs) may improve crop recovery of fertilizer-N, but there is evidence that some EEFs cause a lag in crop growth compared to growth with standard urea. Biomass and mineral nutrient accumulation was investigated in rice fertilized with urea, urea-3,4-dimethylpyrazole phosphate (DMPP) and polymer-coated urea (PCU) to determine whether any delays in bi...
