The Difference

AbstractDietary iron requirements are higher among women of child-bearing age (WCBA) to replenish blood loss during menses, to prevent iron deficiency anaemia and to support a healthy foetus during pregnancy. Low intakes of iron have previously been reported among WCBA in Ireland and across Europe and data from European countries have shown that there is evidence of anaemia and low iron stores in this population group. The aim of this study was to investigate the dietary patterns influencing iron intakes in WCBA (18–50 years) in Ireland.Analyses were based on the National Adult Nutrition Survey (NANS) (2008–2010) (www.iuna.net). A 4 day semi-weighed food record was used to collect food and beverage intake data (including nutritional supplement use) from a nationally representative sample of 1500 adults (487 women (18–50y)). Nutrient intakes were estimated using WISP© based on UK and Irish food composition data. On the basis of mean daily intake of iron, WCBA were divided into three intake groups: low, medium and high. The food groups that accounted for the greatest proportion of the difference between the high (top third) and low (bottom third) of iron intakes were identified.The difference in iron intakes between the high and low intake groups (25 v 6.7mg/d) was 18.3mg/d. Nutritional supplements and ready-to–eat breakfast cereals (RTEBC) (commonly fortified with iron) accounted for 58 and 20% of the difference in intakes between the high and low intake group, respectively. The contribution of nutritional supplements to the difference in iron intakes can be explained by the proportion of users in the high vs low intake group (27% vs < 1%). The contribution of RTEBC to the difference in iron intakes can be explained by both a higher proportion of those in the high vs low intake group consuming RTEBC and those in the high intake group having a higher mean daily intake of RTEBC (78% vs 36%; 32g/d vs 7g/d).Most of the difference in iron intake between high and low consumers is attributable to nutritional supplement use and the patterns of consumption of fortified RTEBC. These findings will aid in the development of strategies to improve iron intakes in WCBA in Ireland.

Study Designs

The use of nonanabolic nutritional supplements for the sake of improving athletic performance is common, and the types of supplements used can have significant implications for the medical care of athletes. This review will address the most common and most controversial nonanabolic nutritional supplements, including recommendations regarding their use. Many supplements are marketed and promoted based on various theoretical benefits, often derived from limited animal studies, without any basis for recommending their human use. Physicians are trained to not recommend a nutritional supplement unless it is known to be effective, whereas athletes are oriented toward trying any supplement or ergogenic aid as long as it is safe, with the hope that it may be effective. The built-in error in most study designs is larger than the difference between winning and not qualifying at elite levels of competition, such that research may not always answer the questions raised by athletes. An honest discussion of the limitations of most supplements, and acknowledgment that some supplements may work some of the time in some athletes, may lead the physician to be more credible and useful to athletes in providing medical care and guidance that support their desire to improve their performance.

Abstract Children’s vegetable consumption is generally below national recommendations in the UK. This study examined predictors of vegetable intake by children aged 1·5–18 years using counts and portion sizes derived from 4-d UK National Diet and Nutrition Survey food diaries. Data from 6548 children were examined using linear and logit multilevel models. Specifically, we examined whether demographic variables predicted vegetable consumption, whether environmental context influenced portion sizes of vegetables consumed and which food groups predicted the presence (or absence) of vegetables at an eating occasion (EO). Larger average daily intake of vegetables (g) was predicted by age, ethnicity, equivalised income, variety of vegetables eaten and average energy intake per d (R2 0·549). At a single EO, vegetables were consumed in larger portion sizes at home, with family members and at evening mealtimes (Conditional R2 0·308). Within EO, certain configurations of food groups such as carbohydrates and protein predicted higher odds of vegetables being present (OR 12·85, 95 % CI 9·42, 17·54), whereas foods high in fats, sugars and salt predicted a lower likelihood of vegetable presence (OR 0·03, 95 % CI 0·02, 0·04). Vegetables were rarely eaten alone without other food groups. These findings demonstrate that only one portion of vegetables was eaten per d (median) and this was consumed at a single EO, therefore falling below recommendations. Future research should investigate ways to encourage vegetable intake at times when vegetables are not regularly eaten, such as for breakfast and as snacks, whilst considering which other, potentially competing, foods are presented alongside vegetables.

The use of nutritional supplements is highly prevalent among athletes. In this cross-sectional study, we assessed the prevalence of nutritional supplement use by a large group of Dutch competitive athletes in relation to dietary counseling. A total of 778 athletes (407 males and 371 females) completed a web-based questionnaire about the use of nutritional supplements. Log-binomial regression models were applied to estimate crude and adjusted prevalence ratios (PR) for the use of individual nutritional supplements in athletes receiving dietary counseling as compared with athletes not receiving dietary counseling. Of the athletes, 97.2% had used nutritional supplements at some time during their sports career, whereas 84.7% indicated having used supplements during the last 4 weeks. The top ranked supplements used over the last 4 weeks from dietary supplements, sport nutrition products and ergogenic supplements were multivitamin and mineral preparations (42.9%), isotonic sports drinks (44.1%) and caffeine (13.0%). After adjustment for elite status, age, and weekly exercise duration, dietary counseling was associated with a higher prevalence of the use of vitamin D, recovery drinks, energy bars, isotonic drinks with protein, dextrose, beta-alanine, and sodium bicarbonate. In contrast, dietary counseling was inversely associated with the use of combivitamins, calcium, vitamin E, vitamin B2, retinol, energy drinks and BCAA and other amino acids. In conclusion, almost all athletes had used nutritional supplements at some time during their athletic career. Receiving dietary counseling seemed to result in better-informed choices with respect to the use of nutritional supplements related to performance, recovery, and health.

Background: Nutritional supplements refer to a product ingested to increase the nutritional content of a normal diet, to fill a dietary need and/or presumed deficiency. The usage and popularity of nutritional supplements, however, raises concerns from a health benefit and risk perspective. In South Africa, there is currently no adequate regulatory framework of enforcement for nutritional supplement products and undeclared constituents by the statutory body, the Medicines Control Council (MCC). Education awareness programmes by organisations that should take consumer protection and the general public health and wellness as a right, needs to be improved. Objectives: To investigate the attitudes toward nutritional supplements by adult gym users from commercial gymnasiums in the Johannesburg North region of South Africa. Methods: A cross-sectional quantitative design, using a selfadministered questionnaire was applied to 364 recruited study participants who attended commercial gymnasiums in Johannesburg North. Results: One hundred and fifty users (41%) claimed that they ‘always’ read the information about the nutritional values, benefits, and side effects of the supplements on the labels prior to use. Three hundred and three users (83%) indicated that the number of users of nutritional supplements in gymnasiums is on the increase. Two hundred and seventy-three (75%) of main information sources for nutritional supplements may be found on the internet, while 292 (80%) indicated the need for gymnasiums to provide educational programmes pertaining to nutritional supplement consumption. Conclusion: Gymnasium users are aware of the increase in nutritional supplement use in commercial gymnasiums. Many of the users were unaware of the potential mislabelling and health concerns regarding these supplements. Therefore there is a need for improved nutritional supplement education programmes and diligence at multiple levels.

Abstract: The aim of our study was to evaluate a hypercaloric sweet milkbased oral nutrition supplement in a prospective 3 day-study designed to assess the taste preferences of this oral nutritional supplement (ONS) in elderly malnourished out-patients and the influence on adherence in daily intake during two months.A total of 28 out-patients with recent weight loss were included in this study. One flavour (chocolate, vanilla or strawberry) was administered each day in a random way during three consecutive days. In the first three days, patients were asked to fulfill two questionnaires in order to reflect ONS tolerance and acceptance. Sweet and aftertaste were better for chocolate flavour than for vanilla or strawberry flavours. Patients who chose vainilla took a total of 96.3+7.4 average bricks during outpatient followup (1.60+0.3 per day), patients who chose chocolate took 76.8+15.0 bricks (1.28+0.8 per day) and patients who chose strawberry bricks taken 60.3+19.5 bricks (1.10+0.7 per day), with a significant difference with vainilla flavour (p <0.01). The improvement of weight (vanilla +1.0+0.8 kg vs chocolate +0.5+0.8 kg vs 0.6+1.0 kg:p=0.03), tricipital skinfols (vanilla +1.5+0.3 mm vs chocolate +1.1+0.4 mm vs 0.7+0.3 mm:p=0.03), prealbumin levels (vanilla +4.2+0.8 mg/dl vs chocolate +3.9+0.7 mg/dl vs +3.6+1.0 mg/dl:p=0.01) and transferrin levels (vanilla +100.0+21.8 mg/dl vs chocolate +75.5+18.8 mg/dl vs 63.8+14.1 mg/dl:p=0.03) was higher in patients treated with vanilla ONS than chocolate or strawberry ONS. The three flavoured ONS taste preferences are similar although the consumption is high in vanilla flavoured ONS.

Background:U.S. Army Soldiers must meet body weight and composition standards and consequently may use nutritional supplements (NS) purported to assist in weight modification (WM). Nutritional supplements are dietary supplements (DS) and foods intended to supplement the diet.Purpose:This study assessed relationships between NS use, demographic characteristics, health-related behaviors, and WM goals among U.S. Army personnel.Methods:Participants (N = 990) self-reported NS use, categorized as energy drinks, sport nutrition products, or DS, and WM goal (lose, gain, or maintain) was ascertained by survey. DS were subcategorized as health, weight-loss, weight-gain, or other DS. Chi-square and logistic regression were used to assess relationships between predictors, NS use, and WM goal. Most respondents (70.3% ± 1.7%) consumed some NS; however, overall NS use was not related to WM goal. Significant relationships were observed between predictors (tobacco use, age, body-mass index, fitness score, general health, and eating habits) and both WM goal and NS use. Respondents attempting to lose or maintain weight were less likely to consume energy drinks and weight-gain DS.Conclusion:WM goal is related to multiple health behaviors including tobacco use, physical fitness score, and self-perception of health and eating behavior. NS are consumed in this population regardless of WM goal.

Abstract Objectives High iron intake has been shown to be associated with poor cognition among older Chinese people. We aimed to examine the association between plant-based iron-related dietary pattern (IDP) and cognitive function in Chinese adults. Methods Longitudinal study data from the China Health and Nutrition Survey (CHNS) during 1991–2006 were used (N = 4852, ≥55 years old). Dietary intake was obtained from a 3-day food record during home visits. Reduced rank regression was used to construct dietary pattern with iron intake as a response variable. Cognitive function was assessed in 1997, 2000, 2004 and 2006. Multivariable mixed linear regression and logistic regression were used in the analyses. Results IDP was characterised by high intake of fresh vegetable, wheat, legume, beverage, offal, rice and whole grain. High IDP intake was associated with poor cognition. In fully adjusted models, across the quartiles of IDP, the odds ratio (95% CI) for poor cognitive function were: 1.00, 1.06 (0.86–1.30), 1.24 (0.99–1.54), and 1.50 (1.17–1.93), respectively. There was a borderline significant interaction between IDP and meat intake (p interaction 0.085). The association between high IDP and poor cognition was only observed among those with no or low intake of meat. With the adjustment of carbohydrate or iron intake, the IDP and cognition association became non-significant. IDP was positively associated with lead intake. The association between IDP and poor cognition was partly mediated by lead intake. Conclusions Plant-based iron-related dietary pattern is associated with poor cognition in Chinese adults, partly due to high intake of carbohydrate, iron and lead. Funding Sources None.

AbstractLow intakes and suboptimal status of vitamin D, riboflavin, vitamin B12, folate and calcium have been reported in older adults across Europe. Dietary strategies to improve micronutrient intakes and status could include food fortification (mandatory or voluntary) and/or the use of nutritional supplements. This study aims to examine the impact of fortified food consumption and nutritional supplement use on nutrient intakes and nutritional status of vitamin D, riboflavin, vitamin B12, dietary folate equivalents (DFE) and calcium in older Irish adults.Analyses were based on the National Adult Nutrition Survey (NANS) (2008–2010). A 4 day semi-weighed food record was used to collect food and beverage intake data (including nutritional supplement use) from a nationally representative sample of 1500 adults (226 older adults (≥ 65y)). Blood samples (n 1126 (n 145 ≥ 65y)) were collected, processed and analysed using standard operating procedures. Nutrient intakes were estimated using WISP© based on UK and Irish food composition data. Fortified foods were identified as those that had one or more micronutrients added in the ingredient list and a nutritional supplement was defined as a supplement containing vitamins and/or minerals (i.e. excludes herbal/non-nutritional supplements). A fortified food consumer or nutritional supplement user was defined as a participant who consumed a fortified food or took a nutritional supplement at any time over the 4-day recording period. Usual intakes of micronutrients were calculated via the NCI-method using SAS© Enterprise Guide and analyses of biomarker data were carried out using SPSS©.The consumption of fortified foods and/or use of nutritional supplements increased mean intakes of vitamin D (3.6 to 6.9μg/d), riboflavin (1.6 to 2.3mg/d), vitamin B12 (4.5 to 6.0μg/d), DFE (228 to 408μg/d) and calcium (784 to 947mg/d) in older Irish adults and reduced the prevalence of inadequate intakes of these micronutrients by up to 40%. Furthermore, consumers of fortified foods and/or nutritional supplements had improved biomarker status and reduced prevalence of low/deficient status for vitamin D (62 vs 16%), riboflavin (65 vs 11%), vitamin B12 (8 vs 0%) and folate (serum folate:18 vs 0%; red blood cell folate: 0% across all groups) when compared to non-consumers.This study has shown that fortified foods and/or nutritional supplements represent an opportunity to improve intakes and status of key micronutrients in older adults. The data presented in this study will serve to inform the development and implementation of updated dietary recommendations for older adults in Ireland.

AbstractObjectiveTo describe the current use of nutritional supplements and their contribution to micronutrient intakes in a representative sample of Irish adults, to evaluate the impact of supplement use on the adequacy of micronutrient intakes and to assess the risk to supplement users of exceeding tolerable upper intake levels (UL).Study design and subjectsFood intake data were collected in 1379 (662 male and 717 female) randomly selected Irish adults aged 18 to 64 years using a 7-day food diary. The current use of nutritional supplements was assessed using a selfadministered questionnaire and respondents entered each supplement as it was consumed into the food diary.ResultsTwenty-three per cent of respondents regularly used nutritional supplements. Twice as many women used supplements as men. The intakes of micronutrients were significantly higher (P < 0.001) in supplement users than in non-users. Micronutrient intakes from food sources were similar in male users and non-users of supplements, but were significantly higher (P < 0.01) in female users, by 3 to 13%, for Fe, Mg, Mn, vitamins C and E and niacin than in non-users. The percentage of female users between 18 and 50 years who had mean Fe intakes below the average requirement (AR) (10 mg) decreased from 50 to 25 when the contribution from supplements was included. The use of supplements reduced the percentage of men who had mean intakes below the AR for Zn from 19 to 13, for riboflavin from 14 to 6 and for vitamin A from 20 to 5, and reduced the percentage of women with intakes below the AR for Ca from 23 to 16 and for riboflavin from 23 to 14. Twenty-one women out of 80 aged between 18 and 50 years, who consumed supplemental folate, achieved the intake of 600 |xg recommended to prevent neural tube defects. Twenty-two per cent of the women who took iron and 15% of the women who took vitamin B$ in supplemental form had mean daily intakes that exceeded that UL for these nutrients. Supplement users did not exceed the UL for the other micronutrients.ConclusionsSupplementation appears to be beneficial in promoting adequate intakes of some micronutrients, particularly Fe and folate in women aged 18–50 years and vitamin A in men. There appears to be little risk to supplement users of experiencing adverse side effects due to excessive intakes of micronutrients.
