Dietary Supplement Use in the United States, 2003–2006

Abstract: Dietary supplement use has steadily increased over time since the 1970s; however, no current data exist for the U.S. population. Therefore, the purpose of this analysis was to estimate dietary supplement use using the NHANES 2003-2006, a nationally representative, cross-sectional survey. Dietary supplement use was analyzed for the U.S. population (≥1 y of age) by the DRI age groupings. Supplement use was measured through a questionnaire and was reported by 49% of the U.S. population (44% of males, 53% of females). Multivitamin-multimineral use was the most frequently reported dietary supplement (33%). The majority of people reported taking only 1 dietary supplement and did so on a daily basis. Dietary supplement use was lowest in obese adults and highest among non-Hispanic whites, older adults, and those with more than a high-school education. Between 28 and 30% reported using dietary supplements containing vitamins B-6, B-12, C, A, and E; 18-19% reported using iron, selenium, and chromium; and 26-27% reported using zinc- and magnesium-containing supplements. Botanical supplement use was more common in older than in younger age groups and was lowest in those aged 1-13 y but was reported by ~20% of adults. About one-half of the U.S. population and 70% of adults ≥ 71 y use dietary supplements; one-third use multivitamin-multimineral dietary supplements. Given the widespread use of supplements, data should be included with nutrient intakes from foods to correctly determine total nutrient exposure.

Micronutritional approaches to periodontal therapy

Abstract: AIM: Periodontitis results from the loss of a delicate balance between microbial virulence factors and a proportionate host response. Nutritional factors have been implicated in several chronic inflammatory diseases that are associated with periodontitis. This manuscript reviews the evidence for nutritional exposures in the etiology and therapeutic management of periodontitis, and makes recommendations for daily nutritional intake for vitamin C (ascorbic acid), vitamin D, calcium, and antioxidants. RESULTS AND CONCLUSION: Periodontitis is associated with low serum/plasma micronutrient levels, which may result from dietary and/or life-style factors as well as nutrigenetic characteristics. Early evidence suggests beneficial outcomes from nutritional interventions; supporting the contention that daily intake of certain nutrients should be at the higher end of recommended daily allowances. For prevention and treatment of periodontitis daily nutrition should include sufficient antioxidants, vitamin D, and calcium. Inadequate antioxidant levels may be managed by higher intake of vegetables, berries, and fruits (e.g. kiwi fruit), or by phytonutrient supplementation. Current evidence is insufficient to support recommendations of mono-antioxidant vitamin supplements and randomised controlled double-blind intervention studies are needed to provide evidence to underpin future recommendations. Inadequate supply of vitamin D and calcium may be addressed by implementing changes in diet/life style or by supplements.

Diet, environmental factors, and lifestyle underlie the high prevalence of vitamin D deficiency in healthy adults in Scotland, and supplementation reduces the proportion that are severely deficient

Abstract: Vitamin D deficiency has recently been implicated as a possible risk factor in the etiology of numerous diseases, including nonskeletal conditions. In humans, skin synthesis following exposure to UVB is a potent source of vitamin D, but in regions with low UVB, individuals are at risk of vitamin D deficiency. Our objectives were to describe the prevalence of vitamin D deficiency and to investigate determinants of plasma 25-hydroxyvitamin D (25-OHD) concentrations in a high northern latitude country. Detailed dietary, lifestyle, and demographic data were collected for 2235 healthy adults (21-82 y) from Scotland. Plasma 25-OHD was measured by liquid chromatography-tandem MS. Among study participants, 34.5% were severely deficient (25-OHD 40 nmol/L). Among participants who were taking supplements, 21.3% had a May-standardized 25-OHD concentration >50 nmol/L, 54.2% had 25-50 nmol/L, and 24.5% had <25 nmol/L, whereas this was 15.6, 43.3, and 41%, respectively, among those who did not take supplements (P < 0.0001). The most important sources of vitamin D were supplements and fish consumption. Vitamin D deficiency in Scotland is highly prevalent due to a combination of insufficient exposure to UVB and insufficient dietary intake. Higher dietary vitamin D intake modestly improved the plasma 25-OHD concentration (P = 0.02) and reduced the proportion of severely deficient individuals (P < 0.0001). In regions with low UVB exposure, dietary and supplement intake may be much more important than previously thought and consideration should be given to increasing the current recommended dietary allowance of 0-10 μg/d for adults in Scotland.

Impact of Season and Diet on Vitamin D Status of African American and Caucasian Children

Abstract: Seasonal variation of vitamin D status and adequacy of dietary vitamin D and impact of race on maintaining vitamin D sufficiency was assessed in 140 healthy 6- to 12-year-old African American (AA) and Caucasian (C) children residing in Pittsburgh, Pennsylvania during summer and winter. Vitamin D insufficiency was not rare in either group (AA vs C, summer, 17.2% vs 14.3%, nonsignificant; winter, 34.1% vs 32.5%, nonsignificant) despite a mean dietary intake of vitamin D above the American Academy of Pediatrics (AAP) recommended intake (400 IU/d; AA vs C, summer, 421 vs 456 IU/d, nonsignificant; winter, 507 vs 432 IU/d, nonsignificant). Race/season and dietary vitamin D were predictors of serum 25-hydroxyvitamin D [25(OH)D] concentrations. However, dietary vitamin D influenced 25(OH)D only in Caucasians during winter. Current AAP recommended daily intake for vitamin D is inadequate for maintaining vitamin D sufficiency in children.

High sodium intake of children through 'hidden' food sources and its association with the Mediterranean diet: the GRECO study.

Abstract: Objectives Sodium is the mineral that has been, mainly, linked to hypertension and cardiovascular disease. It is found naturally in many foods, but is also used in the food industry and manufacturing. Identification of total sodium intake, as well as 'hidden' sodium intake from food sources early in life is necessary. Methods Four thousand, five hundred and eighty children aged 10-12 years were enrolled, in a cross-sectional, population-based survey. Among other measurements, dietary data were obtained by a semi-quantitative food frequency questionnaire, and sodium intake was calculated. High sodium consumption was considered an intake over 2200 mg/day. Adherence to the Mediterranean dietary pattern was evaluated using the Mediterranean Diet Quality Index for children and adolescent score (KIDMED score). Results Twenty-three percent of Greek children had sodium intake which exceeded the 2200 mg/day recommendation, excluding salt added at table and during cooking. Sodium intake was found elevated in children with moderate and high adherence to the Mediterranean Diet. Additionally, 1 unit increase in KIDMED score (i.e. higher adherence) was associated with 10% [odds ratio (OR) 1.10, 95% confidence interval (CI) 1.07-1.13] increased likelihood of consuming sodium above the median intake (i.e. >1500 mg/day). Thirty-four percent of sodium intake from 'hidden' sources came from bread, processed cereals and white cheese. Conclusions Greek children have an elevated sodium intake from 'hidden' sources and main contributors are foods which are recommended to be consumed on a daily basis according to the Mediterranean Diet Pyramid. These findings should induce manufacturers to reduce the amount of sodium added during processing of 'healthy' foods, especially bread and cheese.

Dietary Guidelines for Calcium and Vitamin D: A New Era

Abstract: Ensuring adequate intake of calcium and vitamin D are important nutritional goals for children. They are primarily important for bone growth and development, and recent data suggest the possibility of other important health benefits for these key nutrients throughout life. These new data prompted the Institute of Medicine (IOM) to reevaluate existing dietary recommendations for calcium and vitamin D. On November 30, 2010, the IOM issued a new report that provides dietary recommended intake (DRI) values for calcium and vitamin D for adults and children.1 The final publication of the report will be in 2011; thus, it will be known as the 2011 IOM report. Key pediatric values are shown in Table 1. I was a member of both the previous (1997) and current IOM committees. View this table: TABLE 1 Selected Calcium and Vitamin D DRI Values for Children and Adolescents The previous DRI values provided only adequate intake (AI) values and, in some cases, a tolerable upper intake level (UL) for these key nutrients.2 AI is a single value that would be likely to meet the needs of most children. It is used for infants when either the content of a nutrient in breast milk is the nutritional standard or when limited data are available regarding the average requirements of a population for the nutrient (estimated average requirement [EAR]). Some knowledge or estimate of the variance around the EAR is needed to calculate the recommended dietary allowance (RDA). The better-known RDA is the intake that meets the requirements of nearly all (98%) of the population. Although both values are important in public policy, providers of pediatric care generally advise individual intakes to achieve the RDA to ensure that a child is very likely to meet his or her nutritional needs.

Magnesium intake is associated with strength performance in elite basketball, handball and volleyball players

Abstract: Magnesium plays significant roles in promoting strength. Surveys of athletes reveal that intake of magnesium is often below recommended levels. We aimed to understand the impact of magnesium intake on strength in elite male basketball, handball, and volleyball players. Energy and nutrient intake were assessed from seven-day diet record. Strength tests included maximal isometric trunk flexion, extension, and rotation, handgrip, squat and countermovement Abalakov jump, and maximal isokinetic knee extension and flexion peak torques. Linear regression models were performed with significance at p<0.1. Mean magnesium intake was significantly lower than the recommended daily allowance. Regression analysis indicated that magnesium was directly associated with maximal isometric trunk flexion, rotation, and handgrip, with jumping performance tests, and with all isokinetic strength variables, independent of total energy intake. The observed associations between magnesium intake and muscle strength performance may result from the important role of magnesium in energetic metabolism, transmembrane transport and muscle contraction and relaxation.

Dietary Calcium Intake, Vitamin D Status, and Bone Health in Postmenopausal Women in Rural Pakistan

Abstract: The high prevalence of osteoporosis in Pakistan is of public-health concern. However, there is a paucity of information regarding nutrition and bone density in rural communities. The purpose of this study was to evaluate the dietary and lifestyle factors that impact bone health in Nahaqi. Data were collected from 140 postmenopausal women using an interviewer-administered 24-hour dietary recall questionnaire. Bone mineral density was estimated using the quantitative ultrasound index (QUI). Serum 25(OH)D was measured in fasting blood samples. The QUI scores revealed that 42% and 29% of the women had T-scores, indicative of osteopaenia and osteoporosis respectively. The mean calcium intake was 346 mg/d, which is less than 50% of the recommended daily intake. The QUI correlated with 25(OH)D after controlling for age (p=0.021, r=0.41, r2=0.168). Vitamin D deficiency and low intake of dietary calcium are two key factors contributing to poor bone health in this population.

Nutrient intake variability and number of days needed to assess intake in preschool children

Abstract: The duration of the period of time during which diet should be recorded for sufficiently accurate results on the usual intake of an individual is an especially challenging issue in prospective studies among children. We set out to describe nutrient intake variability in preschoolers and to determine the number of record days required (D) to estimate intake of energy and thirty-two nutrients. The diet and the use of dietary supplements were assessed with three consecutive daily food records including one weekend day in 1639 children participating in the population-based birth cohort of the Type 1 Diabetes Prediction and Prevention Project (DIPP) in Finland. Variance ratios and D stratified by sex and age groups were calculated for 455 (1-year-old), 471 (3-year-old) and 713 (6-year-old) children (born between 1998 and 2003). Within:between variance ratios and D increase with increasing age, and are slightly higher for girls. Vitamin A, cholesterol, n-3 and n-6 fatty acids, β-carotene and folate intakes require the most replicates. Including supplemental intake has an impact on the variance estimates according to the proportion of supplement users. In the DIPP Nutrition Study with 3 d food records, the correlation coefficients between observed and true intakes of energy and thirty-two nutrients averaged 0·91 in 1-year-old children, 0·79 in 3-year-old children and 0·74 in 6-year-old children. For providing accurate nutrient intake estimates, three replicates of food records are reasonable in 1-year-old children but must be questioned for several nutrients in 3- and 6-year-old children. The accuracy of ranking boys is greater than that for girls.

Abstract: Background Epidemiological studies indicate that a well balanced vegetarian diet offers several health benefits including a lower prevalence of prosperity diseases in vegetarians compared to omnivores. It was the purpose of the present study to compare nutritional and physical characteristics in matched samples of institutionalized vegetarian (V) and non-vegetarian (NV) elderly.

Dietary survey in Hungary, 2009. Part I. Macronutrients, alcohol, caffeine, fibre

Abstract: In 2009 Hungarian Food Safety Office (HFSO) performed a countrywide representative dietary survey to obtain food consumption data for quantitative food safety risk assessment utilizable in the field of public health nutrition as well. The consumption of foodstuffs, daily energy- and nutrient intakes, nutritional habits and dietary supplement usage of Hungarian population was assessed. The complex system has included three-day dietary record and a food consumption frequency questionnaire. Some anthropometric parameters were also self-recorded. According to the body mass index, a considerable proportion of both the 31–60 years old males (69%) and females (46%) were overweight or obese. The energy intake of the Hungarian adult population is slightly exceeds the recommendation. The intake of proteins is satisfactory in general. The average intake of total fats is very high (36.1–38.9 energy percent), and the fatty acid composition — mostly the ratio of n-6/n-3 fatty acids — is unfavourable, but the fatty acid...

Dietary and nutritional treatments for attention-deficit/hyperactivity disorder: current research support and recommendations for practitioners.

Abstract: Evidence for dietary/nutritional treatments of attention-deficit/hyperactivity disorder (ADHD) varies widely, from double-blind, placebo-controlled trials to anecdotal. In guiding patients, clinicians can apply the SECS versus RUDE rule: treatments that are Safe, Easy, Cheap, and Sensible (SECS) require less evidence than those that are Risky, Unrealistic, Difficult, or Expensive (RUDE). Two nutritional treatments appear worth general consideration: Recommended Daily Allowance/Reference Daily Intake multivitamin/mineral supplements as a pediatric health intervention not specific to ADHD and essential fatty acids, especially a mix of eicosapentaenoic acid, docosahexaenoic acid, and γ-linolenic acid as an ADHD-specific intervention. Controlled studies support the elimination of artificial food dyes to reduce ADHD symptoms, but this treatment may be more applicable to the general pediatric population than to children with diagnosed ADHD. Mineral supplementation is indicated for those with documented deficiencies but is not supported for others with ADHD. Carnitine may have a role for inattention, but the evidence is limited. Dimethylaminoethanol probably has a small effect. Herbs, although "natural," are actually crude drugs, which along with homeopathic treatments have little evidence of efficacy. Consequences of delayed proven treatments need consideration in the risk-benefit assessment of dietary/nutritional treatments.

Energy Allowances for Solid Fats and Added Sugars in Nutritionally Adequate U.S. Diets Estimated at 17–33% by a Linear Programming Model

Abstract: The 2010 Dietary Guidelines Advisory Committee has recommended that no more than 5–15% of total dietary energy should be derived from solid fats and added sugars (SoFAS). The guideline was based on USDA food pattern modeling analyses that met the Dietary Reference Intake recommendations and Dietary Guidelines and followed typical American eating habits. This study recreated food intake patterns for 6 of the same gender-age groups by using USDA data sources and a mathematical optimization technique known as linear programming. The analytic process identified food consumption patterns based on 128 food categories that met the nutritional goals for 9 vitamins, 9 minerals, 8 macronutrients, and dietary fiber and minimized deviation from typical American eating habits. Linear programming Model 1 created gender- and age-specific food patterns that corresponded to energy needs for each group. Model 2 created food patterns that were iso-caloric with diets observed for that group in the 2001–2002 NHANES. The optimized food patterns were evaluated with respect to MyPyramid servings goals, energy density [kcal/g (1 kcal = 4.18 kJ)], and energy cost (US$/2000 kcal). The optimized food patterns had more servings of vegetables and fruit, lower energy density, and higher cost compared with the observed diets. All nutrient goals were met. In contrast to the much lower USDA estimates, the 2 models placed SoFAS allowances at between 17 and 33% of total energy, depending on energy needs.

Dietary Intake of Participants With Peripheral Artery Disease and Claudication

Abstract: We compared the dietary intake of participants with peripheral artery disease (PAD) and claudication with diet recommendations of the National Cholesterol Education Program (NCEP) and dietary reference intake values recommended by the Institute of Medicine (IOM) of the National Academy of Sciences. Forty-six participants consumed a mean macronutrient composition of 17% protein, 51% carbohydrate, and 30% fat. Compared to the NCEP and IOM recommendations, few participants met the recommended daily intake for sodium (0%), vitamin E (0%), folate (13%), saturated fat (20%), fiber (26%), and cholesterol (39%). Participants with PAD and claudication have poor nutrition, with diets particularly high in saturated fat, sodium, and cholesterol, and low in fiber, vitamin E, and folate intakes. Participants should be encouraged to reduce consumption of dietary fat, saturated fat, cholesterol, and sodium and to increase fiber and vitamin intakes to meet recommendations of the NCEP and IOM.

Antioxidant intake among Brazilian adults - The Brazilian Osteoporosis Study (BRAZOS): a cross-sectional study

Abstract: Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant. Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits. These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

How much is too much? A case report of nutritional supplement use of a high-performance athlete.

Abstract: Although dietary nutrient intake is often adequate, nutritional supplement use is common among elite athletes. However, high-dose supplements or the use of multiple supplements may exceed the recommended daily allowance (RDA) of particular nutrients or even result in a daily intake above tolerable upper limits (UL). The present case report presents nutritional intake data and supplement use of a highly trained male swimmer competing at international level. Habitual energy and micronutrient intake were analysed by 3 d dietary reports. Supplement use and dosage were assessed, and total amount of nutrient supply was calculated. Micronutrient intake was evaluated based on RDA and UL as presented by the European Scientific Committee on Food, and maximum permitted levels in supplements (MPL) are given. The athlete's diet provided adequate micronutrient content well above RDA except for vitamin D. Simultaneous use of ten different supplements was reported, resulting in excess intake above tolerable UL for folate, vitamin E and Zn. Additionally, daily supplement dosage was considerably above MPL for nine micronutrients consumed as artificial products. Risks and possible side effects of exceeding UL by the athlete are discussed. Athletes with high energy intake may be at risk of exceeding UL of particular nutrients if multiple supplements are added. Therefore, dietary counselling of athletes should include assessment of habitual diet and nutritional supplement intake. Educating athletes to balance their diets instead of taking supplements might be prudent to prevent health risks that may occur with long-term excess nutrient intake.

Perceptions of fruit and vegetable dietary guidelines among Australian young adults

Abstract: Aim: Regular consumption of fruit and vegetables has been associated with a decreased risk of a number of chronic diseases. An appropriate level of knowledge is important to successfully adhere to the dietary guidelines for eating fruit and vegetables. However, there is little research about the level of knowledge that young adults have about fruit and vegetable consumption. The current study aimed to investigate the recall and understanding of Australian dietary guidelines, food product and serving size knowledge in a population of young adults. Methods: One hundred and six undergraduate students completed online questionnaires regarding (1) knowledge of dietary recommendations; (2) knowledge of serving size information; and (3) foods that could be included as part of fruit and vegetable intake. Results: The results showed that the sample had significant knowledge gaps in all three areas. Approximately half (54%) of participants correctly reported the recommended daily intake of fruit and vegetables, the majority were not able to correctly report serving sizes (correct responses were 30–61%) and were not able to identify all ingredients from a recipe that counted towards fruit and vegetable intake. Conclusions: Past interventions have not tended to focus on the fruit and vegetable knowledge, or behaviours, of Australian young adults. On the basis of findings from this study, it appears that more work is needed to develop messages to effectively target this important group.

Assessment of vitamin D and vitamin A intake by female students at the United Arab Emirates University based on self-reported dietary and selected fortified food consumption.

Abstract: In the United Arab Emirates (UAE), many adolescent girls and women (especially the UAE citizens) are not adequately exposed to sunlight and their dietary intake of vitamin D is insufficient to fulfill the required recommended daily allowance of the vitamin. In the present study, the problem of vitamin D and vitamin A insufficiency in female students of UAE University was investigated through a dietary intake assessment of the vitamins. Results indicated that over 70% of female students constituting the survey population did not consume enough milk and other vitamin-D-rich foods, and many showed poor food habits. Prevalence of vitamin D insufficiency among the population studied indicated that 37% of the total population was considered vitamin D insufficient and 40% of the female students residing in the hostels also had vitamin D insufficiency ( < 5 μg/day) based on self-reported dietary and selected fortified food consumption.

Nutritional intake of Korean population before and after adjusting for within-individual variations: 2001 Korean National Health and Nutrition Survey Data

Abstract: Accurate assessment of nutrient adequacy of a population should be based on usual intake distribution of that population. This study was conducted to adjust usual nutrient intake distributions of a single 24-hour recall in 2001 Korean National Health and Nutrition Surveys (KNHNS) in order to determine the magnitude of limitations inherent to a single 24-hour recall in assessing nutrient intakes of a population. Of 9,960 individuals who provided one 24-hour recall in 2001 KNHNS, 3,976 subjects provided an additional one-day 24-hour recall in 2002 Korean National Nutrition Survey by Season (KNNSS). To adjust for usual intake distribution, we estimated within-individual variations derived from 2001 KNHNS and 2002 KNNSS using the Iowa State University method. Nutritionally at risk population was assessed in reference to the Dietary Reference Intakes for Koreans (KDRIs). The Korean Estimated Average Requirement (Korean EAR) cut-point was applied to estimate the prevalence of inadequate nutrient intakes except for iron intakes, which were assessed using the probability approach. The estimated proportions below Korean EAR for calcium, riboflavin, and iron were 73%, 41%, and 24% from usual intake distribution and 70%, 51%, and 39% from one-day intake distribution, respectively. The estimated proportion of sodium intakes over the Intake Goal of 2,000 mg/day was 100% of the population after adjustment. The energy proportion from protein was within Korean Acceptable Macronutrient Distribution Ranges (Korean AMDR), whereas that of carbohydrate was higher than the upper limit and that of fat was below the lower limit in the subjects aged 30 years or older. According to these results, the prevalence of nutritional inadequacy and excess intake is over-estimated in Korea unless usual intake distributions are adjusted for one-day intakes of most nutrients.

Changes in Food and Nutrient Intakes of College Students between 1999 and 2009

Abstract: The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin B 6 , phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

Dietary intake in adolescents with asthma--potential for improvement.

Abstract: Associations between an unhealthy diet and overweight and the presence of asthma are reported. The aims of this study were to assess whether the intake of nutrients and food items in adolescents with asthma differs from that of healthy adolescents, whether the intake was in accordance with the Nordic Nutrition Recommendations (NNR) or whether possible relationships were confounded by body composition. A four-day-validated 18-page pre-coded food diary was completed by 169 13- to 14-year-old adolescents, 93 with asthma and 76 healthy control subjects, in addition to clinical assessment, anthropometric measurements, lung function and skin prick tests. Neither intake of added sugar, snacks nor saturated fat was associated with asthma. All groups had an intake of saturated fat and added sugars exceeding the NNR, while the intake of fruits and vegetables, fibre and vitamin D was lower than recommended. The intake of folate, calcium, magnesium and iron was lower than recommended for girls with asthma and healthy girls. The intake of vitamin C was satisfactory for all groups. Body composition did not influence eating habits, and the prevalence of overweight was similar in the two groups. The dietary intake among Norwegian adolescents in general had a potential for improvement. As girls have a lower energy intake than boys, they have a larger demand of quality of the diet. Additional dietary research in adolescents with asthma is recommended.

Nutritional status of Korean elderly by oral health level - based on 2009 national health and nutrition survey data

Abstract: Objectives : The purpose of this study was investigation of quality and qu antity of nutritional intake related oralhealth status among Korean elders. Methods : The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference IntakesFor Koreans(KDRIs). Chi-square test for Complex Samples was use d to determine the relationship between oralhealth and inadequate nutrient intake in Korean elders.The complex samples general linear model was used to test diffe rence of average value difference of nutrientintake percentage compared to dietary reference intake(DRI), en ergy intake rate from three major nutrients,average mean adequacy ratio(MAR) and index of nutritional quali ty(INQ) related oral health status. Age, sex andtotal energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results : We could found the difference of the nutrient intake and the dietary quality related oral health statusamong Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energyintake rate from three major nutrient was lower as oral health status became worse. The percentage of subjectswith nutritional intakes under showed highest level in worst or al health status. As oral health status becameworse, average mean adequacy ratio(MAR) was lower and the numbe r of nutrient of which index of nutritionalquality(INQ) was under 1 was more. Conclusions : From the result above, this study clearly shows the level of oral health affecting the inequalities ofeating and the food for the people. And the various propose of oral health policies is needed for vulnerable groupswho needs solution to solve the problem of inequality of food d istribution where intensive distribution of nutri-tion problem occurred. Sufficient, safe, and a variety of healt hy food intake is a fundamental right of our people.And also, to apply this policy in reality, institutional arrang ements and organizations, and specific performingsystem will be needed.

Assessing the nutritional status of Palestinian adolescents from East Jerusalem: a school-based study 2002-03.

Abstract: In Palestine, there is a little information about nutrition of adolescents compared to other age groups. This study was designed to assess the nutritional status of Palestinian school-aged children (11-16 years) in East Jerusalem during 2002-03. A school-based cross-sectional study targeted randomly 313 adolescents from public and private schools. A previously validated and reliable questionnaire was administered through interviews that included anthropometric and hemoglobin measurements, 24-h dietary intake recall and physical activity questionnaire. It was found that being overweight (24.3%) or obese (9.9%) coexisted with being underweight (4.8%) and/or anemic (23.3%). Only 22.4% of the study subject had physical activity for ≥5 days a week with boys being more physically active than girls (p < 0.01). Inadequate energy intake had 55.66% of boys and 64.81% of girls; inadequate protein intake was reported by 15.07% of boys and 43.08% of girls. The majority of them met <80% of the recommended daily allowances for most micronutrients. The whole sample and especially boys consumed more total, saturated fat, less monounsaturated fat and carbohydrates than what is advised. Obese and overweight adolescents had lower energy intake (p < 0.05) and a lower trend in being physically active than normal weight counterparts. School health education programs targeted at adolescents and parents need to be developed as part of overweight-obesity, malnutrition and anemia prevention.

Assessment of dietary intake in a sample of Polish population - baseline assessment from the prospective cohort 'PONS' study.

Abstract: OBJECTIVE The aim of this study was to assess the dietary intake of participants in the Polish-Norwegian Study (PONS). METHODS The presented study comprised 3,862 inhabitants of Świetokrzyskie Province aged 45-64 (2,572 females and 1,290 males). Daily intakes of energy, protein, carbohydrate, fat and fatty acid were estimated using the Food Frequency Questionnaire (FFQ). RESULTS Energy intake was significantly higher in males than females (1,461.4 vs 1,320.7 kcal/day), and in participants aged 45-54 than in those aged 55-64 (1,409.5 vs 1,338.5 kcal/day). The percentage of energy from saturated fatty acids was higher than dietary recommendations. Protein, fat and carbohydrate intakes were significantly higher in males compared to females, and in younger than in older group. Daily cholesterol intake was significantly higher in males compared to females and in younger than in older group. People with a higher level of education had a higher energy, protein and fat intake. CONCLUSION Under-reporting of energy intake was observed in a significant percentage of participants, especially in males. Gender, age and education status had statistically significant impact on dietary intake. Increase in the intake of dietary fibre, mono- and polyunsaturated fatty acids with diet by the studied participants will make the diets more healthy.
