Project description:Most vitamins are primarily ingested from foods. However, it has been reported that intakes of some vitamins do not meet the nutrition reference values even in high-income countries. In this case, vitamin-fortified foods and/or vitamin supplements are helpful to fix insufficient/deficient status. However, it is not clear whether consumers are aware of their nutritional status or whether they use these products efficiently. To address this issue, we conducted an online cross-sectional questionnaire survey among 14,741 Japanese adults (over 20 years old, 7489 males and 7252 females) concerning the perceptions and prevalence of vitamin-fortified food and/or vitamin supplements. Differences in distribution among groups were compared using the chi-squared test. According to dietary habits, 33.2% of the participants consumed a well-balanced diet every day, but 25.5% could not because of time (41.6%) or money (36.9%) constraints. The perception of each vitamin varied: the highest was for vitamin C (93.2%) and the lowest was for biotin (41.9%). In addition, only a portion of the participants believed that they took sufficient amounts of each vitamin; the highest was vitamin C (22.3%) and the lowest was biotin (5.2%). Despite this situation, most did not use vitamin-fortified food and/or vitamin supplements due to economic reasons. Among vitamin-fortified food and/or vitamin supplement users, the purposes for the usage of these products were varied, such as maintaining health (80.5%), supplementation of nutrients (47.8%), beauty-related purposes (27.5%), and to prevent infectious disease (23.2%). To remedy nutritional status in individuals, it is important to improve not only consumer awareness but also the environment, which can lead consumers to use acceptable vitamin products without any burden.

Project description:Background: The key issue is whether voluntarily fortified foods and vitamin/mineral supplements available on the market serve public health needs. The study aim was to estimate nutrient intakes from voluntarily fortified foods and vitamin/mineral supplements in relation to the Dietary Reference Intake (DRI) in adolescents (n = 759) aged 13-19 who attended public secondary schools in Central-Eastern Poland. Methods: Data on the consumption of voluntarily fortified foods were collected using a semi-quantitative food frequency questionnaire containing 58 food items. Data on the use of dietary supplements were assessed via an open-ended question. The content of nutrients was estimated using the producer's labeling declaration. The distribution of nutrient intakes according to the percentage of DRI categories (<20%, 20-39.9%, 40-59.9%, 60-79.9%, 80-99.9%, 100-119%, or >120%) was estimated. Results: Consumption of voluntarily fortified foods was a common behavior in adolescents (86.7% of participants), while vitamin/mineral supplements were used by less than one-fifth of them (17.7%). The amounts of nutrient intakes from fortified foods and/or supplements were at different levels: (I) vitamins A, D, calcium, magnesium (>50% of adolescents did not exceed 20% of DRI); (II) vitamins E, B12, iron (>50% of respondents consumed at least 20% of DRI); (III) niacin and pantothenic acid (>50% of respondents consumed at least 40% of DRI); IV) vitamins C, B1, B2, B6, folate, biotin (>50% of participants consumed at least 60% of DRI). In a subgroup of respondents who used fortified foods and supplements simultaneously (n = 126), some nutrients (i.e., vitamins C, B1, B2, B6, niacin, and biotin) were consumed in amounts ≥150% of DRI. Intake above the Tolerable Upper Intake Levels was observed for niacin, vitamin A, B6 and folic acid in individual cases (up to 1.1% of respondents); a higher risk of overconsumption was associated with using vitamin/mineral supplements than voluntarily fortified foods. Conclusion: Adolescents should be educated on how to reasonably use fortified foods and dietary supplements to help to overcome the potential deficiency of nutrients without causing excessive consumption.

Project description:PurposeThis study investigates intakes of risk micronutrients from non-fortified foods, fortified foods and food supplements in different age and gender sub-groups of the Dutch population.MethodsThis is a secondary analysis of the Dutch National Food Consumption Survey (DNFCS 2012-2016, N = 4313, 1-79 years). The proportion of the population with Habitual Intakes below the Estimated Average Requirement (EAR) and above the Upper Level (UL) for calcium, iron, zinc, vitamin A, vitamin B6, folate, vitamin D and vitamin E from non-fortified foods, fortified foods and total intake including food supplements was calculated using Statistical Program to Assess Dietary Exposure (SPADE).ResultsMore than 50% of the population had an intake below the EAR for calcium, iron, vitamin D and folate. Intakes were inadequate for certain sub-groups for the other vitamins and minerals. Adolescents and women were the population sub-groups most likely to have an intake below the EAR. For zinc, vitamin A and folic acid, more than 1% of toddlers exceeded the UL from the total intake. A negligible proportion exceeded the UL for the other vitamins and minerals.ConclusionInadequate intakes were found for several micronutrients in various population sub-groups despite an apparently well-nourished population. Intakes of zinc, folic acid and vitamin A from food supplements in toddlers and preschoolers should be investigated further to ensure they do not exceed recommended amounts. These results can be used to inform policy makers and to design nutritional interventions to improve micronutrient intakes in the Netherlands.

Project description:A key challenge of public health nutrition is to provide the majority of the population with a sufficient level of micronutrients while preventing high-consumers from exceeding the tolerable upper intake level. Data of the 2014 Belgian food consumption survey (n = 3200) were used to assess fat-soluble vitamin (vitamins A, D, E and K) intake from the consumption of foods, fortified foods and supplements. This study revealed inadequate intakes for vitamin A, from all sources, in the entire Belgian population and possible inadequacies for vitamin D. The prevalence of inadequate intake of vitamin A was lowest in children aged 3-6 (6-7%) and highest in adolescents (girls, 26%; boys, 34-37%). Except for women aged 60-64 years, more than 95% of the subjects had vitamin D intake from all sources below the adequate intake (AI) of 15 μg/day. The risk for inadequate intake of vitamins K and E was low (median > AI). Belgian fortification and supplementation practices are currently inadequate to eradicate suboptimal intakes of vitamins A and D, but increase median vitamin E intake close to the adequate intake. For vitamin A, a small proportion (1-4%) of young children were at risk of exceeding the upper intake level (UL), while for vitamin D, inclusion of supplements slightly increased the risk for excessive intakes (% > UL) in adult women and young children. The results may guide health authorities when developing population health interventions and regulations to ensure adequate intake of fat-soluble vitamins in Belgium.

Project description:The objective of the present study was to evaluate the contribution of voluntary fortified foods and supplements to reducing micronutrient shortfalls in the UK population. A secondary analysis of the UK National Diet and Nutrition Survey was conducted (2012/13-2013/14, N 2546, 1·5-95 years). Micronutrient intakes were derived from food consumption intake data and food composition data and calculated as the proportion below or above the Dietary Reference Values for males and females of different age groups, for those on a base diet only, users of fortified foods but no supplements and users of fortified foods and supplements. Of the population consuming a base diet only, 21-45 % and 5-29 % fell below the Estimated Average Requirement (EAR) for minerals and vitamins, respectively. About 3-13 % fewer consumers of fortified foods fell below the EAR for vitamins and minerals. Supplements barely reduced the prevalence of intakes below the EAR. Among supplement non-users and users, 99 and 96 % failed to meet the reference intakes for vitamin D. More women than men were at risk of inadequacies of micronutrient intakes. The prevalence of inadequacies declined with increasing age. Voluntary fortified foods but not supplements made a meaningful contribution to intakes of vitamin and minerals, without risk of unacceptably high intakes. These insights may help the UK to define approaches to address micronutrients of concern in vulnerable groups.

Project description:Poor maternal nutrition contributes to poor birth outcomes, including low birth weight and small for gestational age births. Fortified balanced energy protein (BEP) supplements may be beneficial, although evidence is limited. This mixed method study, conducted among pregnant women in Burkina Faso, is part of a larger clinical trial that seeks to understand the impact of fortified BEP supplements on pregnancy outcomes and child growth. The formative research reported here, a single-meal rapid assessment of 12 product formulations, sought to understand product preferences for provision of BEP supplements and contextual factors that might affect product acceptability and use. Results indicate a preference for products perceived as sweet rather than salty/savoury and for products perceived as familiar, as well as a sensitivity to product odours. Women expressed a willingness and intention to use the products even if they did not like them, because of the health benefits for their babies. Data also indicate that household food sharing practices may impact supplement use, although most women denied any intention to share the products. Sharing behaviour should therefore be monitored, and strategies to avoid sharing should be developed during the succeeding parts of the research.

Project description:Micronutrient deficiencies (MNDs) occur as a result of insufficient intake of minerals and vitamins that are critical for body growth, physical/mental development, and activity. These deficiencies are particularly prevalent in lower-and middle-income countries (LMICs), falling disproportionately on the poorest and most vulnerable segments of the society. Dietary diversity is considered the most effective method in reducing this deficiency but is often a major constraint as most foods rich in micronutrients are also expensive and thereby inaccessible to poorer members of society. In recent years, affordable commodities such as staple foods (e.g., cereals, roots, and tubers) and condiments (e.g., salt and oil) have been targeted as "vehicles" for fortification and biofortification. Despite efforts by many countries to support such initiatives, there have been mixed experiences with delivery and coverage. An important but little understood driver of success and failure for food fortification has been the range of business models and approaches adopted to promote uptake. This review examines the different models used in the delivery of fortified food including complementary foods and biofortified crops. Using a keyword search and pearl growing techniques, the review located 11,897 texts of which 106 were considered relevant. Evidence was found of a range of business forms and models that attempt to optimise uptake, use, and impact of food fortification which are specific to the 'food vehicle' and environment. We characterise the current business models and business parameters that drive successful food fortification and we propose an initial structure for understanding different fortification business cases that will offer assistance to future designers and implementors of food fortification programmes.

Project description:Evidence suggests that multiple micronutrient and balanced energy protein (BEP) supplementation during pregnancy can decrease the risk of stillbirth and small-for-gestational-age births and increase birth weight. We conducted a mixed-methods formative research study to identify the most acceptable among a range of 11 candidates fortified BEP supplements for use in pregnancy and lactation in a rural district in Nepal. Forty pregnant women aged 15-40 years participated in a test meal tasting of 11 different sweet and savoury candidate BEP supplements. Each participant rated the products on organoleptic properties using a 7-point hedonic scale (1 = Dislike it very much to 7 = Like it very much), ranked her 'top 3' most liked supplements, and subsequently discussed each product with peers in focus group discussions (FGDs). Five supplements (sweet lipid-based nutrient supplement (LNS), savoury LNS, sweet vanilla biscuits, vanilla instant drinks and seasoned pillows) achieved the maximum overall median hedonic score of 7, with sweet LNS and seasoned pillows ranking as the top 2. This was consistent with the assessments in FGDs. Women in the FGDs expressed dislike of the smell and taste of the cocoa drink, savoury masala bar, sweet mango bar and savoury curry biscuit, which was consistent with the hedonic scale scores. This study provides valuable insights into our understanding of women's acceptance of different BEP supplements during pregnancy in rural Nepal and has helped identify the two most accepted BEP supplements to be used in a two-month home trial to assess utilisation and compliance in this setting.

Project description:Limited data are available on the source of usual nutrient intakes in the United States. This analysis aimed to assess contributions of micronutrients to usual intakes derived from all sources (naturally occurring, fortified and enriched, and dietary supplements) and to compare usual intakes to the Dietary Reference Intake for U.S. residents aged ≥2 y according to NHANES 2003-2006 (n = 16,110). We used the National Cancer Institute method to assess usual intakes of 19 micronutrients by source. Only a small percentage of the population had total usual intakes (from dietary intakes and supplements) below the estimated average requirement (EAR) for the following: vitamin B-6 (8%), folate (8%), zinc (8%), thiamin, riboflavin, niacin, vitamin B-12, phosphorus, iron, copper, and selenium (<6% for all). However, more of the population had total usual intakes below the EAR for vitamins A, C, D, and E (34, 25, 70, and 60%, respectively), calcium (38%), and magnesium (45%). Only 3 and 35% had total usual intakes of potassium and vitamin K, respectively, greater than the adequate intake. Enrichment and/or fortification largely contributed to intakes of vitamins A, C, and D, thiamin, iron, and folate. Dietary supplements further reduced the percentage of the population consuming less than the EAR for all nutrients. The percentage of the population with total intakes greater than the tolerable upper intake level (UL) was very low for most nutrients, whereas 10.3 and 8.4% of the population had intakes greater than the UL for niacin and zinc, respectively. Without enrichment and/or fortification and supplementation, many Americans did not achieve the recommended micronutrient intake levels set forth in the Dietary Reference Intake.

Project description:BackgroundUse of complementary and alternative medicine (CAM), including vitamins, minerals, herbals, and other dietary supplements, is widespread in the United States (ranging from 24% in Hispanics to 50% in American Indians). Pharmacists are an accessible source for healthcare information, but little is known about their use of CAM products and to whom they would recommend these products.MethodsA cross-sectional survey was sent via email to pharmacists licensed in one state in the United States in 2015. The survey included items about their use of 10 vitamins and minerals, and 21 herbal or other dietary supplements, as well as reasons for use, conditions used to treat, if they would recommend the product to patients, family, or friends, their perception of CAM safety and effectiveness, and four demographic questions. Descriptive statistics were used to summarize the data, and a chi-square test was used to determine differences between pharmacists' use of vitamins/minerals and herbals/other dietary supplements. The a priori alpha level was 0.05.ResultsA total of 639 pharmacists completed the survey. Female pharmacists used vitamins/minerals (p = 0.031) and herbals/others (p = 0.039) more than male pharmacists. Older pharmacists used herbals/others more than younger pharmacists (p < 0.001). Fifty-nine percent thought the dietary supplements in the survey were safe while 32% reported they were effective. Seventy-eight percent of respondents reported use of any vitamin or mineral product versus 42% who reported use of any herbal or other dietary supplement. Commonly used products included: multivitamins (91%), vitamin C (71%), fish oil (65%), probiotics (53%), and fiber (53%). The most commonly reported reason for use was general health and wellness (17-90%). Pharmacists most commonly recommend fiber/psyllium (94%) and calcium (90%) to patients, family, and friends.ConclusionsPharmacists in this survey selectively used vitamins, minerals, herbals and other dietary supplements, and recommended some of the more commonly used products to patients, family and friends. This is valuable information given that pharmacists are frontline healthcare professionals who may be asked to provide advice about these products.
