Dietary Vitamin D

Three experiments were conducted to measure the effects of dietary vitamin D, phosphorus and calcium on zearalenone (Z) toxicosis in female weanling rats Experiments were of completely randomized design and were for 14 days. All diets were supplied to groups of 15 rats with or without 250 μg Z/g feed. Vitamin D was fed at 0, 555, 1113, 2225 and 4450 IU per kg diet. There was no significant correlation between dietary vitamin D level and feed consumption, feed efficiency, plasma phosphorus or plasma calcium. Final body weight was negatively correlated with dietary vitamin D for rats fed both levels of Z. Dietary phosphorus was supplied at 0.00, 0.23, 0.45, 0.91 and 1.40% and this resulted in curvilinear correlations between phosphorus and final body weight, feed consumption and feed efficiency. Plasma calcium concentration was negatively correlated with dietary phosphorus. A positive correlation was seen between dietary levels of phosphorus and plasma concentrations of phosphorus. Calcium was fed at 0, 0.25, 0.58, 1.00 and 2.00% but no effect of dietary calcium was seen on body weights or feed efficiencies, while feed consumption was correlated with dietary calcium but only for those rats fed Z. Plasma concentrations of calcium rose with dietary calcium while there was a simultaneous drop in plasma phosphorus concentration. The plasma changes were more pronounced in those rats fed Z. In all experiments, inclusion of Z in diets caused depressions in final body weight, feed consumption and feed efficiency compared to rats fed the same diet devoid of Z.

The Women’S Health Initiative

The relationship between vitamin D and glaucoma is controversial. The objective of this study was to examine women from the Women’s Health Initiative (WHI) to determine if there is an association between vitamin D and incident glaucoma in postmenopausal women. We examined the association between dietary vitamin D intake, vitamin D supplements and serum 25 hydroxyvitamin D (25(OH)D) levels and the risk of developing glaucoma. 143,389 postmenopausal women from the WHI including a subset with serum 25(OH) D measurements were examined to determine the association of dietary, supplemental and serum levels of vitamin D to the development of glaucoma. Dietary intakes of vitamin D, use of vitamin D supplements and serum levels of 25(OH) D were predictors examined for the main outcome of incident glaucoma. In multivariable models adjusted for demographic, clinical variables and medication use, dietary vitamin D, vitamin D supplements, total vitamin D intake (diet plus supplements) and serum 25 (OH) D measurements were not significantly associated with incident glaucoma. In the CaD placebo-controlled intervention clinical trial, there was also no association in the active intervention arm with glaucoma. We conclude that dietary vitamin D intake, supplements and serum levels are not significantly related to the risk of developing glaucoma in postmenopausal women.

Abstract Objectives To assess maternal dietary intake and adequacy at postpartum and to determine whether lifestyle characteristics and breastfeeding status are related to nutrient intakes. Methods We analyzed cross-sectional data from a convenience sample of 129 mothers at 18-mo postpartum, whose families were enrolled into a randomized toddler intervention trial, in the Lower Mainland, British Columbia, Canada. The Canadian Diet History Questionnaire II (C-DHQ II) was used to estimate usual dietary intake in the mothers during the preceding 12 months (i.e., between 6- to 18-mo postpartum). Implausible energy intakes were defined as <600 kcal/day or >3500 kcals/day, and excluded from analysis. Demographic and lifestyle characteristic data about the pregnancy and postpartum time period were collected using a questionnaire. Results Maternal mean (SD) age at birth was 33.5 (4.0) years and most women were of European (46%) or Asian (38%) ethnicity, and had Bachelor's degree or higher education (70%). About 75%, 88%, and 89% did not meet their dietary requirements (i.e., intake below the EAR) for fiber, potassium, and vitamin D intakes, from food only, respectively. Considering total dietary intake from food and supplements, the prevalence of dietary vitamin D inadequacy was 25%. Women of European ethnicity had higher vitamin D intake (median (IQR) in mg/1000kcal/day: 19.5 (7.26,101)) compared to Asian women (10.8 (3.87, 21.1); P < 0.05). Dietary vitamin D intake was higher in breastfeeding (i.e., providing breastmilk as primary milk source, i.e., ³2 times/day, to their 18-mo old toddlers) compared to non- or occasionally breastfeeding mothers (20.0 (10.5, 61.1) versus 14.9 (4.28, 26.7) mg/1000kcal/day; P < 0.05). Conclusions While most Canadian mothers in this sample met the EARs for most nutrients, the prevalence of dietary inadequacy was very high for vitamin D, potassium, and fiber. Some population groups may be especially at risk of developing nutrient deficiencies in this period of life characterized by postpartum recovery and transition; targeted public health strategies may be needed to address these deficiencies.
