Silicon Level

Silicon in nutritional amounts provides benefits for bone health and cognitive function. The relationship between silicon intake from a common daily diet and silicon blood level has been scarcely elucidated, so far. The aim of this study was to analyze the associations between plasma silicon levels and the total and bioavailable silicon intake—along with the contribution of silicon made by food groups—in a healthy adult Polish population. Si intake was evaluated in 185 healthy adults (94 females and 91 males, aged 20–70) using a 3-day dietary recall and a database on the silicon content in foods, which was based on both previously published data and our own research. Fasting plasma silicon levels were measured in 126 consenting subjects, using graphite furnace atomic absorption spectrometry. The silicon intake in the Polish population differed significantly according to sex, amounting to 24.0 mg/day in women and 27.7 mg/day in men. The median plasma silicon level was 152.3 µg/L having no gender dependency but with a negative correlation with age. Significant correlations were found between plasma silicon level and total and bioavailable silicon intake, as well as water intake in the diet (r = 0.18, p = 0.044; r = 0.23, p = 0.011; r = 0.28, p = 0.002, respectively). Silicon intakes from non-alcoholic beverages, cereal foods, and carotene-rich vegetables were also positively associated with plasma silicon levels. These results may help establish dietary silicon recommendations and formulate practical advice on dietary choices to ensure an appropriate supply of silicon. The outcome of this study, however, needs to be confirmed by large-scale epidemiological investigations.

Background: Suaahara, a large-scale integrated program, aimed to improve diets and nutritional status among women and children, in part by facilitating enhanced homestead food production (EHFP). Objective: This study examines associations between EHFP and maternal and child dietary diversity and variations by season and agroecological zone (AEZ): mountains and terai. Methods: We used data from household monitoring surveys (n = 2101 mothers; n = 994 children, 6-23 months), which included a 7-day dietary recall and maternal report on participation in 5 EHFP activities—received vegetable seeds, chicks, and technical support and participated in training and EHFP groups. We constructed binary variables for each activity and a scale (0-5) summing participation. For dietary diversity, we used the Women’s Dietary Diversity Score using 10 food groups and 7 food groups for child diets. Multivariable linear regression analyses were used to assess associations between EHFP participation and dietary diversity by season and AEZ, controlling for potential confounders and clustering. Results: In adjusted models, we found positive associations between dietary diversity and chicks, technical support, and EHFP beneficiary groups; the magnitude of the associations varied by season and AEZ. The degree of participation in 5 EHFP activities was positively associated with maternal dietary diversity in the terai (β = .24, P < .001) and mountains (β = .12, P = .01) and child dietary diversity in the terai (β = .35, P < .001) during the winter. No associations were found in the rainy season. Conclusion: Our findings highlight the potential for EHFP to address dietary diversity constraints among this population. Variation by subnational setting and seasonality suggest that policies and programs should be contextualized.

Introduction: Two studies were conducted to evaluate the National Cancer Institute (NCI)’s web-based Automated Self-Administered 24-hour Recall (ASA24) system, which was developed to facilitate the collection of 24-hour dietary recalls in large-scale research. Hypothesis: Energy, nutrient and food group estimates, response rates, and preferences are comparable between ASA24 and USDA’s interviewer-administered Automated Multiple-Pass Method (AMPM). Methods: Study 1 assessed the response rates and data collected using ASA24 compared to AMPM. About 1200 participants were recruited from three integrated health systems using quota sampling to ensure representation of a range of ages and race/ethnicity groups. Participants were asked to complete two 24HRs, 4-7 weeks apart, and randomized into four study groups: 1) two ASA24s; 2) two AMPMs; 3) ASA24 first and AMPM second; and 4) AMPM first and ASA24 second. Study 2 assessed the validity of ASA24 compared to AMPM in a one-day feeding study. Eighty-one participants visited a study center to consume three meals from a buffet. All containers were unobtrusively weighed before and after each participant served him/herself; plate waste was also weighed. The next day, participants returned to the center to complete either ASA24 or AMPM. Results: Study 1: Almost all enrolled participants (95%) completed at least one recall and 80% completed two; response rates did not differ by recall mode. Estimated intakes of energy, nutrients and food groups were comparable for ASA24 and AMPM; for example, energy, 2132 vs. 2126 kcal; fat, 84.9 vs. 82.8 g; saturated fatty acids, 27.9 vs. 26.9 g; fiber, 18.4 vs. 18.4 g; and fruits and vegetables, 3.0 vs. 3.1 cup equivalents. Of participants randomized to complete one ASA24 and one AMPM, a greater percentage preferred ASA24. Study 2: The examination of foods and drinks reported showed that exact or close matches were recalled for 76.9% of items truly consumed among ASA24 respondents compared to 82.5% among AMPM respondents. Far matches were reported for 3.1% of items consumed among ASA24 respondents compared to 0.7% for AMPM. The proportions of foods or drinks consumed but not reported (exclusions) were 20.4% and 16.8% for ASA24 and AMPM, respectively. Median differences between reported and true intakes for energy, nutrient and most food groups were not significantly different between ASA24 and AMPM. Conclusion: ASA24 performs well relative to traditional interviewer-administered recalls and is feasible for use in large-scale research. The tool, which offers significant savings over interviewer-administered recalls, is publicly available from NCI and has been used in over 800 studies to collect over 113,000 dietary recalls. The tool is currently being updated to run on mobile applications.

Abstract52 coal ash samples from individual households were analyzed to determine the pH and the concentrations of four toxic elements: arsenic, cadmium, lead and thallium. The method used was atomic absorption spectrometry with graphite-furnace atomization. The ash samples originated from various coal grades and statistical analysis showed existing correlations between the concentrations of studied elements, pH and the coal grades. The maximum concentrations of arsenic, cadmium, lead and thallium were 50,900, 43,500, 128,900, and 6660 µg/kg, respectively. The results were compared with the published data for the ash of industrial origin.

Abstract A reliable and rapid method is described for the determination of chromium in alcoholic beverages by electrothermal atomic absorption spectrometry (ETAAS) after optimization of the temperature-time program for the graphite furnace. Chromium in wines was determined directly without sample pretreatment. Other samples were first mineralized with HN03 and V2O5. The method was validated, and its analytical characteristics were checked. The detection limit was 1 pg (for a sample volume of 10 μL). Accuracy was 99.20 ± 3.80% for wines and 98.90 ± 2.00% for other beverages. Precision ranged from 3.50 to 4.50%. The proposed method was applied to 124 samples of alcoholic beverages frequently consumed in Spain. Mean values obtained (μg/L) were 20.28 for wines, 8.75 for beer, 7.85 for cider, 14.60 for brandy, 7.50 for rum, 10.25 for whisky, 8.80 for gin, 9.25 for vodka, 24.45 for anisette, and 10.08 for liquors. The advantages of the proposed method (rapidity, sensitivity) and versatility) make it useful for routine analyses and for estimations of dietary intake of chromium
