TL;DR: Daily consumption of approximately the recommended daily intake of vitamin A did not increase breast milk retinol concentrations in this sample of Ghanaian women.
Abstract: BACKGROUND: Vitamin A deficiency remains a global public health problem. Daily supplementation with a lipid-based nutrient supplement (LNS) has potential for increasing milk vitamin A concentrations. OBJECTIVE: The objective of this study was to determine whether daily supplementation with approximately the recommended daily intake of vitamin A in an LNS or a multiple-micronutrient supplement (MMN) during pregnancy and the first 6 mo postpartum has an effect on breast milk retinol concentration at 6 mo postpartum. METHODS: Women

TL;DR: Good status for folate, vitamin B6, and vitamin B12 in the highly active women is documented in this nutrition assessment using both dietary (food and dietary supplements) and biochemical assessments among highly active and sedentary women.
Abstract: Background: Female athletes and active women require adequate nutrition for optimal health and performance. Nutrition assessments are needed to identify potential nutrients of concern. Folate, vitamin B6, and vitamin B12 function in important pathways used during physical activity and female athletes may be at risk for poor status of these micronutrients. This cross-sectional study described a comprehensive nutrition assessment of the B-vitamins (folate, vitamin B6, and vitamin B12) using both dietary (food and dietary supplements) and biochemical assessments among highly active and sedentary women. Methods: Highly active (n = 29; age 20 ± 2 years; body mass index (BMI) 23.8 ± 3.5 kg/m2) and sedentary (n = 29; age 24 ± 3 years; BMI 22.6 ± 3.0 kg/m2) women were recruited for this study. Participants completed 7-day weighed food records and a fasting blood draw. Results: Although the highly active women reported higher intakes of energy (p < 0.01), folate (p < 0.01), vitamin B6 (p < 0.01), and vitamin B12 (p < 0.01), no significant differences were found between the groups for biomarkers of folate, vitamin B6, and vitamin B12. All of the highly active women had biomarkers within the desired reference ranges, suggesting good status. In general, most participants were able to meet the 1998 Recommended Daily Allowance (RDA) from food alone. For the women that reported using dietary supplements, micronutrient intakes met the 1998 RDA and in some cases, exceeded the Tolerable Upper Intake Level. Conclusion: This nutrition assessment documented good status for folate, vitamin B6, and vitamin B12 in the highly active women. Similar assessment approaches (food, dietary supplements, and biomarkers) should to completed with other nutrients of concern for the female athlete.

TL;DR: The results of dietary Se intake estimation showed that Se intake for the observed group of female subjects from Zagreb area is lower than in the majority of European countries, and lower than the value recommended by the World Health Organisation.
Abstract: Data about selenium (Se) concentrations in the environment and its daily dietary intake in Croatia are scarce. The aim of this study was to estimate daily dietary Se intake in a group of female subjects from the Zagreb area using three different approaches: direct measurement of Se in collected daily duplicate portions, daily dietary records and the indirect method of Se analysis in serum. The results were 33.2±8.82, 30.9±7.40 and 37.8±5.45 μg day–1 (arithmetic mean ±SD) by duplicate portion, daily dietary records and the serum Se method, respectively. The results of dietary Se intake estimation showed that Se intake for the observed group of female subjects from Zagreb area is lower than in the majority of European countries, and lower than the value recommended by the World Health Organisation.

TL;DR: The relation is sigmoid with eGFR up-regulation for (on)U-ureaN >5.19 mg/h, a threshold approximately corresponding to the recommended daily allowance for protein intake (0.8 g/day per kg of ideal weight).
Abstract: Background Kidney function measured as estimated glomerular filtration rate (eGFR) is a risk factor for mortality and severe diseases Protein intake up-regulates kidney function The dose-response curve of eGFR over protein intake is unknown Urinary urea nitrogen is an objective index of protein intake Methods The study cross-sectionally analysed the relation between overnight urinary urea nitrogen ((on)U-ureaN) and eGFR with and without control for other variables in 4106 adults of the Gubbio population Analyses were done for serum creatinine (S-cr) also to investigate the independency of results from eGFR calculation Results Higher (on)U-ureaN associated with higher eGFR, and lower S-cr independently of sex and age (simple and partial correlation coefficients >0100, P 1012 mg/h, respectively) Multi-variable spline regression indicated that the relation of eGFR over (on)U-ureaN was non-significant for (on)U-ureaN 1012 mg/h (coefficient = +005, 95% CI = -006/ +016, P = 0394) eGFR differed by ≈8 mL/min × 173 m(2) between the lowest and highest 20% of (on)U-ureaN distribution Conclusions Higher protein intake relates to higher eGFR The relation is sigmoid with eGFR up-regulation for (on)U-ureaN >519 mg/h, a threshold approximately corresponding to the recommended daily allowance for protein intake (08 g/day per kg of ideal weight)

TL;DR: Vitamin and mineral supplementation may be warranted for individuals following some diet plans, as not one of the 11 diets evaluated provided 100% of the U.S. recommended daily allowances.
Abstract: The objective of this study was to determine the nutritional adequacy of some of the popular published diet plans. Diet analyses were made using the University of Massachusetts Nutrient Data Bank. Not one of the 11 diets evaluated provided 100% of the U.S. Recommended Daily Allowances for the 13 vitamins and minerals studied. The nutrients most often below recommended levels were thiamin, vitamin B-6, vitamin B-12, calcium, iron, zinc, and magnesium. Vitamin and mineral supplementation may be warranted for individuals following some diet plans.
