Protein, Calcium, Vitamin D Intake and 25(OH)D Status in Normal Weight, Overweight, and Obese Older Adults:A Systematic Review and Meta-Analysis

The aging process is often accompanied by increase in body weight. Older adults with overweight or obesity might have an overconsumption in energy that is accompanied by inadequate intake of protein, vitamin D, and calcium. It is unclear if intake of protein and vitamin D and calcium is sufficient in older adults with overweight/obesity, and whether it differs from older adults with normal weight, since a recent overview of the literature review is lacking. Therefore, we systematically analyzed the current evidence on differences in nutrient intake/status of protein, vitamin D and calcium between older adults with different body mass index (BMI) categories. Randomized controlled trials and prospective cohort studies were identified from PubMed and EMBASE. Studies reporting nutrient intake/status in older adults aged ≥50 years with overweight/obesity and studies comparing between overweight/obesity and normal weight were included. Nutrient intake/status baseline values were reviewed and when possible calculated for one BMI category (single-group meta-analysis), or compared between BMI categories (meta-analysis). Nutrient intake/status was compared with international recommendations. Mean protein (N = 8) and calcium intake (N = 5) was 0.98 gram/kilogram body weight/day (g/kg/d) [95% Confidence Interval (CI) 0.89–1.08] and 965 mg [95% CI: 704–1225] in overweight/obese. Vitamin D intake was insufficient in all BMI categories (N = 5). The pooled mean for vitamin D intake was 6 ug [95% CI 4–9]. For 25(OH)D, the pooled mean was 54 nmol/L [95% CI 45–62], 52 nmol/L [95% CI 46–58], and 48 nmol/l [95% CI 33–62] in normal (N = 7), combined overweight and obese (N = 12), and obese older adults (N = 4), respectively. In conclusion, older adults with overweight and obesity have a borderline sufficient protein and sufficient calcium intake, but insufficient vitamin D intake. The 25(OH)D concentration is deficient for the obese older adults

The Relationship Between Vitamin D and Calcium/Dairy Intake and Obesity in Children

Objective: The aim of this study is to examine the relationship between vitamin D and calcium intake and obesity in a population of young adolescents who participated in a Vitamin D and Sunlight Exposure study in Pittsburgh, PA. Participants: 252 healthy 6 to 14.9 year old young adolescents (54% male, 69% African American) were recruited between June 2006 and December 2009. Main outcome measures: Weight status, BMI, vitamin D intake, calcium intake, vitamin D and calcium rich food intake. Results: A significant difference by race was observed with 30.1% of African Americans and 8.5% of Caucasians being obese (P\u3c0.01). No difference was found by gender. Median (25%, 75%) vitamin D intake in the total population was 254.9 IU (146.8, 407.3) which is below the level recommended by the Institute of Medicine. Median calcium intake in the total population was 1193.6 mg (752.8, 1161.1) which met recommended guidelines. Median vitamin D intake differed by weight status (normal, overweight, obese) in the total population (259.5 IU, 325.2 IU and 181.9 IU, respectively; P=0.015). A similar pattern was observed for calcium (1193.4 mg, 1416.3 mg and 911.6 mg, respectively; P=0.016). No correlation was found between vitamin D or calcium intake and BMI in the total population or by race and gender. Conclusion: Vitamin D and calcium intake was significantly different based on weight status, particularly in obese and African American subjects. Vitamin D intake in the population was reportedly below recommended guidelines. Further research is necessary to determine the ideal vitamin D and calcium intake in children for optimal health status, including longitudinal studies to better assess the relationship between vitamin D and calcium intake and weight status

The Relationship Between Serum 25-Hydroxyvitamin D, Vitamin D and Calcium Intake, and Adiposity in Infants

Purpose: National prevalence of childhood overweight and obesity has plateaued in recent years, but rates remain high, with approximately 10% among children“high weight.” The relationship between adiposity and serum 25-hydroxyvitamin D [25(OH)D] status has been well-explored in older individuals, with inconsistent results. Furthermore, previous studies have suggested a relationship between adequate consumption of calcium and vitamin D and healthy weight status in older children and adults. However, in the infant population, there are few studies detailing the interaction between body composition and serum 25(OH)D or intake of calcium and vitamin D. Our study aims were to assess the association between serum 25(OH)D and body composition and to examine the association between adiposity and dietary intake of calcium and vitamin D in a sample of infants and toddlers. Methods: Our population included healthy male and female infants and toddlers from Pittsburgh, PA who participated in the “Practices Affecting Vitamin D Status in Pittsburgh Infants and Toddlers” study. Parents completed a Vitamin D and Sunlight Exposure Questionnaire, which assessed dietary intake of foods high in calcium and vitamin D as well as daily sunlight exposure (≥2 hours vs. \u3e2 hours). Anthropometric measures and bloodwork for serum 25(OH)D were obtained during at the time of the study visit. Weight-for-length (WFL) percentile status was determined using WHO growth standards (low weight97.7 %ile) and WFL z-scores were calculated. ANOVA was used to compare mean serum 25(OH)D and calcium and vitamin D intake by WFL status. Chi square analysis was used to evaluate the relationship between serum 25(OH) D status (deficient =/mL, insufficient = 12-20 ng/mL, sufficient \u3e20 ng/mL), calcium intake status (sufficient = \u3e700 mg), vitamin D intake status (sufficient = \u3e400 IU) and WFL percentile status. Pearson’s correlation coefficient was used to assess the strength and significance of associations between serum 25(OH)D, calcium and vitamin D intake and WFL z-score. The analysis was repeated after subdivision by race and sun exposure. Results: 125 infants and toddlers (9 to 24 months of age, 68% African American) participated in the study. Approximately 11% of the population had a high weight. Mean vitamin D intake (~600 IU/d) and median calcium intake (~1550 mg/d) exceeded recommendations. Prevalence of high weight was higher among children with adequate intake compared to those who consumed less than the recommendations (calcium: 41% vs. 36%, respectively; vitamin D: 45% vs. 29%, respectively). However, this difference was not statistically significant. Mean serum 25(OH)D level (37 ng/mL) was sufficient. When compared across WFL status, neither mean serum 25(OH)D nor mean intake of calcium and vitamin D varied significantly. No significant correlation was found between WFL and serum 25(OH)D for the cohort or any of the subgroups examined. Conclusions: Rates of infant overweight and obesity in our sample are similar in comparison with the national average. Our results do not support a relationship between calcium and vitamin D intake on weight status or an association between serum vitamin D and body composition in children of this age. Future studies are needed to re-examine these relationships in a larger group of children of more evenly distributed weight status

Do Soup Kitchen Meals Contribute to Suboptimal Nutrient Intake & Obesity in the Homeless Population?

The double burden of suboptimal nutrient intake and obesity exists when available foods lack essential nutrients to promote health and provide high amounts of energy. This study evaluated the nutrition content of 41 meals served to the homeless at 3 urban soup kitchens. The mean nutrient content of all meals and of meals from each of the kitchens was compared to two-thirds of the estimated average requirement (EAR). The mean nutrient content of the meals did not provide two-thirds of the EAR for energy, vitamin C, magnesium, zinc, dietary fiber, or calcium but provided 11.8% of calories from saturated fat. On average one meal did not meet homeless individuals’ estimated requirements; however, 2 meals did meet estimated requirements but provided inadequate fiber and high amounts of energy, saturated fat, and sodium. Soup kitchen meals may contribute to the high prevalence of obesity and chronic disease reported in the homeless, food insecure population

Serum 25-hydroxyvitamin D and bone turnover markers in Palestinian postmenopausal osteoporosis and normal women

Summary This study evaluated the association of vitaminD and bone markers with the development osteoporosis in Palestinian postmenopausal women. Even though vitamin D deficiency was very high for the recruited subjects, it was not associated with osteoporosis except for bones of the hip. Age and obesity were the strongest determining factors of the disease. Purpose The purpose of this study was to investigate the association of bone mineral density (BMD) with serum vitamin D levels, parathyroid hormone (PTH), calcium, obesity, and bone turnover markers in Palestinian postmenopausal women. Methods Three hundred eighty-two postmenopausal women (≥45 years) were recruited from various women clinics for BMD assessment (131 women had osteoporosis and 251 were normal and served as controls). Blood samples were obtained for serum calcium, PTH, 25(OH)D, bone formation (N-terminal propeptide (PINP)), and bone resorption (serum Cterminal telopeptide of type I collagen (CTX1)) markers. Results Women with osteoporosis had statistically significant lower mean weight, height, body mass index (BMI), and serum calcium (p < 0.05) compared to controls. No significant differences were detected between the mean values of bone turnover markers (CTX and PINP), 25(OH)D, and PTH of the two groups. Women with vitamin D deficiency (severe and insufficiency) represented 85.9% of the study subjects. Multiple and logistic regression showed that age and BMI significantly affected BMD and vitamin D had a significant association with BMD only at the lumbar spine. BMI was positively correlated with BMD and PTH but negatively correlated with vitamin D. Logistic regression showed that the odds ratio (OR) for having osteoporosis decreased with increasing BMI (overweight OR = 0.11, p = 0.053; obese OR = 0.05, p = 0.007). Conclusions There was no direct correlation between BMD and PTH, bone turnover markers, and vitamin D except at the lumbar spine. A negative correlation between BMD and age and a positive correlation with BMI were observed. The protective effect of obesity on osteoporosis was complicated by the effect of obesity on vitamin D and PTH.This work was supported in part by a special grant from the Palestinianministry of education and higher education (MEHE)

Hypothalamic Vitamin D Improves Glucose Homeostasis and Reduces Weight

Despite clear associations between vitamin D deficiency and obesity and/or type 2 diabetes, a causal relationship is not established. Vitamin D receptors (VDRs) are found within multiple tissues, including the brain. Given the importance of the brain in controlling both glucose levels and body weight, we hypothesized that activation of central VDR links vitamin D to the regulation of glucose and energy homeostasis. Indeed, we found that small doses of active vitamin D, 1α,25-dihydroxyvitamin D3 (1,25D3) (calcitriol), into the third ventricle of the brain improved glucose tolerance and markedly increased hepatic insulin sensitivity, an effect that is dependent upon VDR within the paraventricular nucleus of the hypothalamus. In addition, chronic central administration of 1,25D3 dramatically decreased body weight by lowering food intake in obese rodents. Our data indicate that 1,25D3-mediated changes in food intake occur through action within the arcuate nucleus. We found that VDR colocalized with and activated key appetite-regulating neurons in the arcuate, namely proopiomelanocortin neurons. Together, these findings define a novel pathway for vitamin D regulation of metabolism with unique and divergent roles for central nervous system VDR signaling. Specifically, our data suggest that vitamin D regulates glucose homeostasis via the paraventricular nuclei and energy homeostasis via the arcuate nuclei

Looking Beyond the Marketing Claims of New Beverages: Health Risks of Consuming Sports Drinks, Energy Drinks, Fortified Waters, and Other Flavored Beverages

Consumption of several new categories of beverages has increased significantly in recent years. Sold in cans and bottles in many venues and heavily marketed as health and strength enhancing, these beverages have become popular among children and adolescents as well as adults. Energy drinks, sports drinks, fruit drinks, flavored waters, and sweetened teas and coffees are known collectively as fortified beverages due to the natural and artificial ingredients that are added in the processing of their main ingredient, water. In view of their rising popularity, it is important to assess the healthfulness of these beverages and the implications of their consumption by the general public. Consumption by youth, to whom marketing is often targeted, is of particular interest in view of children's potentially increased vulnerability to chemicals and other added substances. Further, the possible contribution of these beverages to the high prevalence of childhood obesity merits attention.This report will discuss the major categories of fortified beverages, presenting data on their nature, their ingredients, their similarities and differences, the possible effects on children of their consumption, and areas for further research

Вміст кальцію та вітаміну D3 у хворих на морбідне ожиріння до та після оперативного лікування залежно від виду хірургічного втручання

Obesity is the global problem of mankind. Overweight and obesity are among the five major risk factors for death. In the modern world, the problem of obesity is also discussed in the context of noncommunicable diseases, leading to significant difficulties for society. All obese patients are at risk of vitamin D deficiency and the development of secondary hyperparathyroidism, especially patients with morbid obesity. The purpose was to analyze the dynamics of changes in the levels of vitamin 25(OH)D and calcium in patients with morbid obesity before and after biliopancreatic diversion (BPD) in the modification of Hess-Marceau and sleeve gastrectomy. Materials and methods. Prospectively, 57 patients with morbid obesity and concomitant metabolic syndrome aged 21 to 62 years (mean age 40.00 ± 1.38 years) were examined, they underwent surgery and were monitored at the surgical department 1 of the Dnepropetrovsk Medical Academy of Ministry of Health of Ukraine for 3 or more years after the operation. The distribution of patients in groups was carried out taking into account the applied method of surgical treatment. Clinical group 1 included 29 (50.9 %) patients with BPD; group II — 28 (49.1 %) patients with sleeve gastrectomy. In all patients, the levels of calcium and vitamin 25(OH)D in the blood serum were determined. Evaluation of the study results was carried out in the dynamics of observation — at the first visit and within 3 years after surgery. Results. Analysis of the dynamics of morbid obesity after surgical treatment showed general trends to a significant (from p < 0.01 to p < 0.001) decrease in body mass index and body mass index (BMI) in patients of all clinical groups within 3 months after the start of treatment. In group 1, a significant decrease in indicators occurred within 18 months, and in group 2 — within 6–12 months. There was a decrease in the content of vitamin 25(OH)D and calcium at the beginning of the study, which required drug correction. In the course of the study, there was a tendency to decrease in the vitamin 25(OH)D content in patients of both groups within 12 months after bariatric intervention, with significant changes in the BPD group. In subsequent observation periods (after 1.5 and 2 years), such discrepancies from baseline in patients of both groups disappeared (p < 0.05 for all comparisons). A direct correlation was established between the levels of vitamin D and calcium and the length of a common loop during BPD: rs = +0.382 (p < 0.05) and rs = +0.378 (p < 0.05), respectively. At the same time, the length of the loop did not significantly affect the rate of weight loss after BPD (p > 0.05). Conclusions. The established direct correlation between the levels of vitamin D and calcium in the blood serum of patients who underwent BPD with the length of the common loop testified to the effectiveness of the BPD technique developed during the study (increasing the length of the common loop up to 1 m), the application of which led to a decrease in disturbances of the vitamin-calcium metabolism while maintaining the general tendency to a weight loss

A DAY WITHOUT FAFH IS A DAY WITH BETTER NUTRITION

Two day food intakes from the continuing Survey of Individual Food Intake is used to compare nutrition of individuals who on one day had a FAFH meal and on the other did not. It is found that nutrition on the FAFH day is consistently worse for almost all population subgroups. In particular, significantly more calories are consumed on a day with FAFH meal.Food Consumption/Nutrition/Food Safety,
