TL;DR: This analysis is based on the responses of participants in the most recent Nationwide Food Consumption Survey in 1987–88, and the data are descriptive of nutrient intake of a large number of Americans.
Abstract: This analysis is based on the responses of participants in the most recent Nationwide Food Consumption Survey in 1987–88. The data are descriptive of nutrient intake of a large number of Americans. The results do not provide population estimates for the United States.

TL;DR: A case-control study within the same cohort of women attending the Canadian National Breast Screening Study to check whether a depletion of vitamin D could be detected in the diet of breast cancer patients as compared to controls.
Abstract: It has been stated recently that atmospheric acid haze containing sulfur dioxide and sulfate crystals may lead to vitamin D deficiencies in exposed populations and increase breast cancer mortality, especially in Montreal. In view of the implications of this hypothesis, we have done a case-control study within the same cohort of women attending the Canadian National Breast Screening Study to check whether a depletion of vitamin D could be detected in the diet of breast cancer patients (n = 108) as compared to controls (n = 322) or a random sample of 1,141 women in our Montreal centre as well as 40 breast cancer cases for which precise food intake data were available by way of a 24-hour dietary journal. The mean daily intake of vitamin D of breast cancer cases was 1.65 +/- 2.48 I.U./kg while in 322 controls matched for age the mean intake was 1.34 +/- 1.17 (S.D.). It has to be pointed out that in the 5 years before diagnosis, cancer patients had not increased significantly their consumption of foods rich in vitamin D, namely milk, cheese, yoghurt, butter and fish. It has also to be stressed that, in relation to the recommended daily intake, twice as many breast cancer patients than controls had a higher consumption of vitamin D.

TL;DR: It is concluded that a habitual calcium intake exceeding 800 mg/day (the current Recommended Daily Allowance for adults) is ineffective in preventing cortical bone loss during early menopause.
Abstract: During an 8-year follow-up study, the effect of habitual dietary calcium intake on cortical bone loss in 154 healthy perimenopausal women was examined Dietary calcium intake, determined by the cross-check dietary history method, and cortical bone mineral content of the radius were measured annually Habitual dietary calcium intake was calculated as the mean of the estimated daily dietary calcium intake during the follow-up period The women were classified according to their habitual calcium intake: those with an intake below 800 mg/day (n = 28), between 800 and 1350 mg/day (n = 95), and above 1350 mg/day (n = 31) The results show a continuous significant loss of cortical bone in all groups, amounting yearly to 13 +/- 025, 15 +/- 010, and 19 +/- 023% (mean +/- SE) for the groups with a low, medium, and high habitual calcium intake, respectively (P less than 001) The differences among the three groups did not reach statistical significance (P = 011) Body mass index was found to be positively correlated with the negative changes in cortical bone mineral density (r = 032, P less than 001), even after adjustments had been made for confounding factors It is concluded that a habitual calcium intake exceeding 800 mg/day (the current Recommended Daily Allowance for adults) is ineffective in preventing cortical bone loss during early menopause Body mass index is of major importance for the perimenopausal bone loss

TL;DR: Gender and age had an important influence in the dialysis adequacy, as men presented lower dialysisadequacy and younger adults presented better dialysis inadequacy.
Abstract: To characterize the nutritional status of renal failure patients and its relationship with hemodialysis adequacy measured by Kt/V, a study was carried out with a population of 44 adult patients with renal failure and mean age 51+/-15 years. Anthropometric data, such as dry weight, height, arm circumference, triceps skinfold thickness, mid-arm muscle circumference, and body mass index were assessed, and biochemical tests were conducted for urea, potassium, creatinine, serum albumin, and phosphorus levels, in addition to hemogram and quarterly urea reduction rate average (Kt/V). In order to evaluate calorie intake, a dietary questionnaire on habitual daily food ingestion was administered, taking into consideration the hemodialysis date. The patients were divided into 2 separate groups for the statistical analysis, with 50% of the patients in each group: A (Kt/V 1.2). The data were tabulated as mean and standard deviation, with differences tested by Student's t test. The correlations between variables were established by the coefficient p of Pearson. Most of the patients (43%) were considered eutrophic, based on the BMI, and presented inadequate calorie intake, corresponding to 88.5+/-24% (30.8 kcal/kg actual weight) of the total energy required and adequate protein intake, reaching 109.9+/-40% of the recommended daily allowance (1.24 g/kg of actual weight). There was a correlation of Kt/V with anthropometric parameters such as body mass index, arm circumference, and mid-arm muscle circumference. The biochemical parameters related to dialysis adequacy were albumin, ferritin, and urea (predialysis). Well-dialyzed patients presented better levels of serum albumin. There was an influence of gender and age on correlations of the analyzed variables. Female and younger patients presented better dialysis adequacy. The dialysis adequacy was related to the nutritional status and influenced by the protein intake and body composition. Gender and age had an important influence in the dialysis adequacy, as men presented lower dialysis adequacy and younger adults presented better dialysis adequacy. Further research is necessary to understand better how to facilitate effective and efficient techniques for the nutritional status assessment of hemodialysis patients.

TL;DR: Results improve the knowledge on choline intake in Europe that could be further refined by the collection of choline composition data for foods consumed by the European population and the subsequent assumption made to assess their intake levels.
Abstract: Choline is an important nutrient for humans. Choline intake of the European population was assessed considering the European Food Safety Authority European Comprehensive Food Consumption Database and the United States Department of Agriculture Nutrient Database. Average choline intake ranges were 151–210 mg/d among toddlers (1 to ≤3 years old), 177–304 mg/d among other children (3 to ≤10 years old), 244–373 mg/d among adolescents (10 to ≤18 years old), 291–468 mg/d among adults (18 to ≤65 years old), 284–450 mg/d among elderly people (65 to ≤75 years old) and 269–444 mg/d among very elderly people (≥75 years old). The intakes were higher among males compared with females, mainly due to larger quantities of food consumed per day. In most of the population groups considered, the average choline intake was below the adequate intake (AI) set by the Institute of Medicine in the USA. The main food groups contributing to choline intake were meat, milk, grain, egg and their derived products, composite dishes and fish. The main limitations of this study are related to the absence of choline composition data of foods consumed by the European population and the subsequent assumption made to assess their intake levels. Given the definition of AI, no conclusion on the adequacy of choline intake can be drawn for most European population groups. Such results improve the knowledge on choline intake in Europe that could be further refined by the collection of choline composition data for foods as consumed in Europe.
