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.

The Impact

Ecological restoration often involves revegetation. I have investigated the impact of revegetation on the distribution, abundance and body condition of skinks on Stephens Island (Takapourewa). I tested the prediction that only one, Oligosoma infrapunctatum, of the four skink species (Oligosoma lineoocellatum, O. nigriplantare polychroma, O. infrapunctatum andO. zelandicum) will benefit in terms of abundance and distribution from revegetation. Stephens Island is a Wildlife Sanctuary in the north-western Marlborough Sounds, New Zealand. The island is known for its diverse and abundant reptile community. Prior to the mid 19th century Stephens Island was covered in forest. Nearly 80% of this forest was destroyed following the establishment of a lighthouse and farm on the island in 1894. In 1989, when the control of Stephens Island passed to the Department of Conservation, reforestation became a key conservation goal. Stephens Island is currently a mosaic of different habitat types from pasture to coastal forest. Pitfall traps caught skinks for a mark-recapture study in four replicated habitat types: forest, tussock, pasture and replanted.<br><br>Oligosoma lineoocellatum comprised 75% of all individuals caught. Densities of O. lineoocellatum were higher in replanted habitat (3020/ha in December and 3770/ha in March) than tussock (2690/ha in December and 2560/ha in March) and lowest in the pasture (1740/hain December and 1960/ha in March). Rates of captures were too low to perform density estimates for the other three species. Trap occupancy rates indicate O. nigriplantare polychroma is more common in the tussock habitat, and O. infrapunctatum is more common in the replanted habitat. Few O. zelandicum were found, primarily in the tussock habitat. Pasture areas replanted 13 years ago (now scrub habitat) support a higher diversity and abundance of skinks. Forest areas remain depauperate of skinks. Skink preference for replanted areas suggests that, for now, revegetation benefits their populations, possibly due to greater food sources, lower predation pressure and a wider thermal range.<br><br>Body condition (log weight/ log snout-vent length) and proportion of tail loss of skinks were similar in the different habitat types. However, both O. nigriplantare polychroma and O.lineoocellatum had higher body condition in the replanted than the tussock habitat. Juvenile skinks had significantly lower body condition and a lower proportion of tail loss. Skink body condition was not negatively affected by revegetation or by different habitats, despite the large differences between the habitats. Revegetation currently benefits skink populations. Maintaining a mosaic of habitat types is recommended, because, should revegetation create more forest habitat through plantations or plant succession, it is likely that the population of all four species of skink will decline.<br>

The Impact

The objective of this work was to quantify the impact of the voluntary fortification of foods on dietary intakes of vitamins and minerals of Irish adults. Foods that were voluntarily fortified were identified and pre- and post-fortification levels of micronutrients were determined from data supplied by manufacturers and food composition tables. Using food consumption data in 1379 adults aged 18–64 years, estimated using a 7-d food diary during the North/South Ireland Food Consumption Survey, intakes of micronutrients were determined, both including and excluding the fortification component in foods. Of approximately 3000 foods recorded as consumed, 1·9 % were fortified, mainly breakfast cereals and beverages. Median micronutrient content of fortified foods (FF) ranged from 18–33 % EC RDA per typical serving. Among consumers (65 % of men, 68 % of women), FF contributed, on average, 3·9 % (men) and 5·0 % (women) to mean daily intake (MDI) of energy. Relative to their contribution to MDI of energy, FF contribute a greater % MDI for Fe (men 16, women 19), folate (men 18, women 21), vitamins B1(men 14, women 16), B2(men 16, women 18), B6(men 12, women 15), D (men 5, women 11), B12(men 5, women 7) and niacin (men 10, women 12). Fortification significantly improved the adequacy of intake of some micronutrients, particularly of riboflavin, folate, vitamin D and Fe in women and did not contribute to an increased risk of adverse effects from excessive intake of any micronutrient.

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.

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 CONTEXT AND OBJECTIVE: Bariatric surgery has been an effective alternative treatment for morbid obesity and has resulted in decreased mortality, better control over comorbidities and reduced use of drugs. The objective of this study was to analyze the impact of bariatric surgery on medication drug and nutritional supplement use. DESIGN AND SETTING: Longitudinal study of before-and-after type, on 69 morbidly obese patients in a public hospital in Porto Alegre. METHODS: Through interviews, the presence of comorbidities and use of drugs with and without prescription were evaluated. RESULTS: Among the 69 patients interviewed, 85.5% had comorbidities in the preoperative period, with an average of 2.3 (± 1.5) per patient. The main comorbidities reported were hypertension, diabetes and dyslipidemia. 84.1% of the patients were using prescribed drugs in the preoperative period. The mean drug use per patient was 4.8, which decreased to 4.4 after the procedure. The surgery enabled significant reduction in use of most antidiabetic (84%), antilipemic (77%) and antihypertensive drugs (49.5%). On the other hand, there was a significant increase in use of multivitamins and drugs for disorders of the gastrointestinal tract. The dosages of most of the drugs that continued to be prescribed after surgery were decreased, but not significantly. CONCLUSION: After bariatric surgery, there were increases in the use of vitamins, gastric antisecretory drugs and antianemic drugs. Nevertheless, there was an overall reduction in drug use during this period, caused by suspension of drugs or dose reduction.

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 evaluate the impact of the disaggregation of composite foods on intake estimates of meat and individual meat categories and on the contribution of meat to nutrient intakes in Irish adults.DesignData were analysed from the North/South Ireland Food Consumption Survey, which used a 7-day food diary to estimate food intake. Of 742 food codes that contained meat, 320 were codes for meat consumed as an individual portion and 422 were composite foods and were disaggregated to estimate the meat content.SubjectsA nationally representative sample of 475 men and 483 women (not pregnant or lactating) from the Republic of Ireland aged 18–64 years.ResultsThe mean intake of meat was 134 g day−1in consumers (98.5%) and men (168 g day−1) consumed significantly more (P< 0.001) than women (102 g day−1). Mean intakes of meat were higher in subjects with manual skilled occupations (P< 0.01) and lower in those with third-level educational qualifications (P< 0.05). Without disaggregating meat from composite foods, meat intake was overestimated by 43% (57 g day−1) and varied widely by meat category. Meat disaggregated from composite foods contributed 25% of meat intake. The contribution meat made to nutrient intakes ranged from 29% for protein, vitamin B12, zinc and niacin to 20% for vitamin D, 16% for vitamin B6, 15% for thiamine and 14% for iron.ConclusionsFailure to disaggregat meat from composite foods substantially overestimates meat intake, with a large variation between meat categories. This has important implications for estimates of meat intakes in nutritional epidemiological studies and for food safety purposes.

Background: Nutritional supplements are defined as any dietary supplement manufactured product that is generally intended to supplement the diet when taken by mouth as a pill, capsule, tablet, or liquid. Currently, the use of nutritional supplements is on the increase worldwide, predominantly in Western countries but also more recently expanding to other parts of the world for what has become a multibillion-dollar global industry. As a result, consumer demand has caused the increase in the advertising and marketing of these products. This contributes to early exposure to nutritional supplements by potential consumers and is an influencing factor for the use of performance-enhancing and/or appearance substances by adolescents. For the nutritional supplement industry the container is thus the manifestation of innovative ideas for the enterprising business-minded mogul. For the consumer, body image and ideal body discrepancy, and social influences manifest in the belief that the perfection of body development cannot be achieved without the use of nutritional supplements. This makes the consumer a captive audience for the industry and a challenge for the health care provider when suggesting alternatives to nutritional supplements, based on cost- benefit, and risk assessment. Objective: To determine the association between commercial gym goers and nutritional supplements, in particular the commencement of use, reasons and purpose for use, and the financial and risk implications of use. Methods: A self-administered questionnaire based on a cross-sectional quantitative design and systematic convenience sampling was given to the 364 recruited males and female gym goers. Results: This study’s finding shows that the main reasons why females attend gyms are for muscle gain (57%), weight loss (48%), staying healthy (47%), and a ‘spiritual motive’ (39%) In males, it is predominantly for muscle gain (54%). Protein supplements were the most popular products that were consumed (84%) followed by carbohydrates (72%) and vitamins (71%). It was found that the consumption of nutritional supplements often starts at high school age and continues into adulthood. The analysis shows that natural source protein products are better priced than nutritional supplement products. Conclusion: The study shows the importance of educating gym goers, the general public, and the guardians of minors to make a behaviour change towards nutritional supplement consumption. The change should also incorporate a cost-benefit risk assessment which is practical for the consumer when comparing supplement use as alternative sources of protein. Keywords: alternative protein, body image, cost, gender, spiritual motives
