Lifestyle Factors Association with BMI in Greek Male Conscripts

We determined associations between various lifestyle factors and body mass index (BMI) in 4326 conscripts of the Greek Army, aged 18-27 years. Prevalence of overweight was 32.3% and of obesity 13.2%. Prevalence of underweight was 1.2% and correlated with the level of education (τ=-0.32, p=0.01). In multivariate analysis we found that lower BMI levels were associated with living in urban areas (OR: 0.93, CI: 0.87-0.98, p=0.019), with more time spend in sporting activities (OR: 0.65, CI: 0.61-0.70, p<0.001), and with more juice consumption (OR: 0.75, CI: 0.67-0.83, p<0.001). On the contrary, higher BMI levels were associated with beverage and alcohol consumption (OR: 1.26, CI: 1.14-1.39, p<0.001, and OR: 1.15, CI: 1.04-1.28, p=0.007, respectively). Education and cigarette smoking were not correlated with BMI. In conclusion, prevalence of underweight was correlated with the level of education and obesity was associated with living in rural areas, physical inactivity, heavy alcohol drinking, consumption of sugar sweetened beverages, and low consumption of orange juice.

Orange juice (poly)phenols are highly bioavailable in humans

We assessed the bioavailability of orange juice (poly)phenols by monitoring urinary flavanone metabolites and ring fission catabolites produced by the action of the colonic microbiota. Our objective was to identify and quantify metabolites and catabolites excreted in urine 0-24 h after the acute ingestion of a (poly)phenol-rich orange juice by 12 volunteers. Twelve volunteers [6 men and 6 women; body mass index (in kg/m(2)): 23.9-37.2] consumed a low (poly)phenol diet for 2 d before first drinking 250 mL pulp-enriched orange juice, which contained 584 μmol (poly)phenols of which 537 μmol were flavanones, and after a 2-wk washout, the procedure was repeated, and a placebo drink was consumed. Urine collected for a 24-h period was analyzed qualitatively and quantitatively by using high-performance liquid chromatography-mass spectrometry (HPLC-MS) and gas chromatography-mass spectrometry (GC-MS). A total of 14 metabolites were identified and quantified in urine by using HPLC-MS after orange juice intake. Hesperetin-O-glucuronides, naringenin-O-glucuronides, and hesperetin-3'-O-sulfate were the main metabolites. The overall urinary excretion of flavanone metabolites corresponded to 16% of the intake of 584 μmol (poly)phenols. The GC-MS analysis revealed that 8 urinary catabolites were also excreted in significantly higher quantities after orange juice consumption. These catabolites were 3-(3'-methoxy-4'-hydroxyphenyl)propionic acid, 3-(3'-hydroxy-4'-methoxyphenyl)propionic acid, 3-(3'-hydroxy-4'-methoxyphenyl)hydracrylic acid, 3-(3'-hydroxyphenyl)hydracrylic acid, 3'-methoxy-4'-hydroxyphenylacetic acid, hippuric acid, 3'-hydroxyhippuric acid, and 4'-hydroxyhippuric acid. These aromatic acids originated from the colonic microbiota-mediated breakdown of orange juice (poly)phenols and were excreted in amounts equivalent to 88% of (poly)phenol intake. When combined with the 16% excretion of metabolites, this percentage raised the overall urinary excretion to ∼ 100% of intake. When colon-derived phenolic catabolites are included with flavanone glucuronide and sulfate metabolites, orange juice (poly)phenols are much-more bioavailable than previously envisaged. In vitro and ex vivo studies on mechanisms underlying the potential protective effects of orange juice consumption should use in vivo metabolites and catabolites detected in this investigation at physiologic concentrations. The trial was registered at BioMed Central Ltd (www.controlledtrials.com) as ISRCTN04271658.

Impact of orange juice consumption on bone health of the U.S. population in the national health and nutrition examination survey 2003-2006.

Orange juice (OJ) fortified with calcium (Ca) and vitamin D has turned OJ into a readily available source of these nutrients for children and adults. However, the impact of OJ consumption on Ca and vitamin D adequacy and bone health has not been documented. The aim of this study was the evaluation of the contribution of 100% OJ consumption to dietary and serum Ca and vitamin D status, and bone health parameters in the U.S. population aged 4 years and older (n=13,971) using the National Health and Nutrition Examination Survey (NHANES) 2003-2004 and 2005-2006. Food consumption data were coded to produce micronutrient intake values using the USDA Food and Nutrient Database for Dietary Studies 3.0. Serum concentrations of bone-related micronutrients and biomarkers, bone mineral density (BMD), and bone mineral content (BMC) were measured. Analysis of data was conducted using SAS software 9.2 and SUDAAN. OJ consumers showed higher intakes of bone-related micronutrients, compared with nonconsumers (P<.05). In addition, OJ consumers had higher serum Ca levels in adults (P<.01) and had a lower odds ratio for serum 25-hydroxyvitamin D3 <20 ng/mL in children (P<.05). OJ consumption was positively associated with femur BMD in children (P<.05) and with femur BMC in both children and adults (P<.05). In conclusion, OJ may be recommended as an effective dietary means of improving the status of Ca and vitamin D, acid-base balance, and of promoting bone health in children and adults.

High-Fiber Orange Juice as a Nutrition Supplement in Women: A Randomized, Double-Blind, Placebo-Controlled Study of Tolerance and Effectiveness.

The daily consumption of dietary fiber is frequently below suggested recommendations. Using a double-blind, controlled, randomized study, we assessed the efficiency and tolerance of a fiber-enriched orange juice to supplement fiber intake in women. After 1 week of noninterventional observation, 192 healthy adult women ingested 400 mL of orange juice for 21 days, which either was not (placebo group) or was enriched with fiber (fiber group). Orange juice ingestion was registered daily and controlled for each week during the study period. Macronutrient, fiber, and energy intake were determined using a 3-day food record, validated food chemical composition databases, and the "Pro Diet" software. Gastrointestinal symptoms were self-evaluated daily by scoring 4 grades of symptom intensity and using a visual analog scale to grade pain severity. No changes were observed for macronutrient and energy ingestion. For the placebo group (n = 97), the total fiber intake record was under the daily recommended value. In contrast, the fiber group (n = 95) displayed higher comparative values of total and soluble fiber consumption (P ≤ .001), achieving the daily recommended values of fiber intake. Both groups reported an increased frequency of slight bloating and rumbles over time (P ≤ .05). The fiber group also experienced a higher frequency of slight flatulence over time (P = .002). Consumption of fiber-enriched orange juice was efficient to achieve the daily fiber intake recommendation for women, was not accompanied by intense adverse events, and may represent a suitable method to supplement fiber intake in woman.

Effect of fresh orange juice intake on physiological characteristics in healthy volunteers.

Background. Impaired endothelial function is a predictor of cardiovascular events. Orange juice (OJ) is rich in dietary flavonoids and could inhibit oxidative stress and inflammatory responses. We examined the effects of commercial (COJ) and fresh orange juice (FOJ) on endothelial function and physiological characteristics in healthy humans. Materials and Methods. Twenty-two healthy volunteers years were enrolled in a single blind randomized crossover controlled trial. The two groups consumed either COJ for the first 4 weeks and then FOJ (CFOJ, 4 weeks), or FOJ for the first 4 weeks and then COJ (FCOJ, 4 weeks). We assessed endothelial function by measuring flow-mediated dilation, serum concentrations of lipids, apolipoproteins A and B (apo A-1 and apo B), and inflammatory markers such as vascular endothelial adhesion molecule 1 (VCAM-1), E-selectin, high-sensitivity C-reactive protein (hs-CRP), and interleukin-6. Results. Consumption of both juices decreased VCAM, hs-CRP, and E-selectin but increased apo A-1. A decline in LDL occurred in the FOJ group. There were no differences between the characteristics of two groups, with the exception of apo A-1 levels that were increased with both forms of OJ. The largest variations occurred with hs-CRP, VCAM in both groups. Conclusion. Consumption of COJ and FOJ produced beneficial effects on the physiological characteristics of healthy volunteers. Although these results could encourage the consumption of OJ, intervention studies are needed to determine the long-term effects of these types of OJ on metabolic and cardiovascular endpoints.

Drinking Orange Juice Increases Total Antioxidant Status and Decreases Lipid Peroxidation in Adults

Cardiovascular disease (CVD) is the leading cause of death in the world and is the primary cause of mortality among Americans. One of the many reasons for the pathogenesis of CVD is attributed to eating diets high in saturated fat and refined carbohydrates and low in fruits and vegetables. Epidemiological evidence has supported a strong association between eating diets rich in fruits and vegetables and cardiovascular health. An experiment was conducted utilizing 24 adults with hypercholesterolemia and hypertriglyceridemia to evaluate the impact of drinking 20 fl oz of freshly squeezed orange juice daily for 90 days on blood pressure, lipid panels, plasma antioxidant capacity, metabolic hormones, lipid peroxidation, and inflammatory markers. Except for addition of drinking orange juice, subjects did not modify their eating habits. The findings suggested that drinking orange juice does not affect (P>.1) blood pressure, lipid panels, metabolic hormones, body fat percentage, or inflammatory markers. However, total plasma antioxidant capacity was significantly increased (P<.05) and lipid peroxidation was significantly decreased (P<.05) after orange juice consumption. Drinking orange juice may protect the cardiovascular system by increasing total plasma antioxidant status and by lowering lipid peroxidation independent of other cardiovascular risk markers evaluated in this study.

Multinutrient-Fortified Juices Improve Vitamin D and Vitamin E Status in Children: A Randomized Controlled Trial

BackgroundProvision of fortified juices may provide a convenient method to maintain and increase blood fat-soluble vitamins. ObjectiveTo determine whether children consuming orange juice fortified with calcium and combinations of vitamins D, E, and A could increase serum 25-hydroxyvitamin D [25(OH)D], α-tocopherol, and retinol levels. DesignA 12-week randomized, double-blind, controlled trial. Participants/settingOne hundred eighty participants (aged 8.04±1.42 years) were recruited at Tufts (n=70) and Boston University (n=110) during 2005-2006. Of those recruited, 176 children were randomized into three groups: CaD (700 mg calcium+200 IU vitamin D), CaDEA (700 mg calcium+200 IU vitamin D+12 IU vitamin E+2,000 IU vitamin A as beta carotene), or Ca (700 mg calcium). Children consumed two 240-mL glasses of CaD, CaDEA, or Ca fortified orange juice daily for 12 weeks. Main outcome measuresSerum 25(OH)D, α-tocopherol, and retinol concentrations. Statistical analysesChanges in 25(OH)D, α-tocopherol, retinol, and parathyroid hormone concentrations were examined. Covariates included sex, age, race/ethnicity, body mass index, and baseline 25(OH)D, α-tocopherol, retinol, or parathyroid hormone levels. Multivariate models and repeated measures analysis of variance tested for group differences with pre–post measures (n=141). ResultsBaseline 25(OH)D was 68.4±27.7 nmol/L (27.4±11.10 ng/mL) ), with 21.7% of participants having inadequate 25(OH)D (<50 nmol/L [20.03 ng/mL]). The CaD group's 25(OH)D increase was greater than that of the Ca group (12.7 nmol/L [5.09 ng/mL], 95% CI 1.3 to 24.1; P=0.029). The CaDEA group's increase in α-tocopherol concentration was greater than that in the Ca or CaD groups (3.79 μmol/L [0.16 μg/mL], 95% CI 2.5 to 5.1 and 3.09 μmol/L [0.13 μg/mL], 95% CI −1.8 to 4.3), respectively (P<0.0001). Retinol levels did not change, and body weight remained as expected for growth. ConclusionsDaily consumption of orange juice providing 200 IU vitamin D and 12 IU vitamin E increased 25(OH)D and α-tocopherol concentrations in young children within 12 weeks.

Long-term orange juice consumption is associated with low LDL-cholesterol and apolipoprotein B in normal and moderately hypercholesterolemic subjects

BackgroundThis study investigated the hypothesis that long-term orange juice consumption (≥ 12 months) was associated with low risk factors for cardiovascular disease in adult men and women with normal and moderately high cholesterol blood levels.MethodsThe sample consisted of 103 men (18–66 y) and 26 women (18–65 y); all were employees of an orange juice factory with daily access to free orange juice. The results showed that 41% of the individuals consumed 2 cups (480 mL) of orange juice per day for at least twelve months, while 59% of the volunteers are non-consumers of orange juice.ResultsOrange juice consumers with normal serum lipid levels had significantly lower total cholesterol (−11%, p <0.001), LDL-cholesterol (−18%, p < 0.001), apolipoprotein B (apo B) (−12%, p < 0.01) and LDL/HDL ratio (−12%, p < 0.04) in comparison to non-consumers, as did the consumers with moderate hypercholesterolemia: lower total cholesterol (−5%, p <0.02), LDL-cholesterol (−12%, p <0.03), apolipoprotein B (−12%, p <0.01) and LDL/HDL ratio (−16%, p <0.05) in comparison the non-consumers counterparts. Serum levels of homocysteine, HDL- cholesterol and apolipoprotein A-1, body composition and the dietary intake of food energy and macronutrients did not differ among orange juice consumers and non-consumers, but vitamin C and folate intake was higher in orange juice consumers.ConclusionLong-term orange juice consumers had lower levels of total cholesterol, LDL-cholesterol, apo B and LDL/HDL ratio and an improvement of folate and vitamin C in their diet.

Soda and Other Beverages and the Risk of Kidney Stones

Not all fluids may be equally beneficial for reducing the risk of kidney stones. In particular, it is not clear whether sugar and artificially sweetened soda increase the risk. We prospectively analyzed the association between intake of several types of beverages and incidence of kidney stones in three large ongoing cohort studies. Information on consumption of beverages and development of kidney stones was collected by validated questionnaires. The analysis involved 194,095 participants; over a median follow-up of more than 8 years, 4462 incident cases occurred. There was a 23% higher risk of developing kidney stones in the highest category of consumption of sugar-sweetened cola compared with the lowest category (P for trend=0.02) and a 33% higher risk of developing kidney stones for sugar-sweetened noncola (P for trend=0.003); there was a marginally significant higher risk of developing kidney stones for artificially sweetened noncola (P for trend=0.05). Also, there was an 18% higher risk for punch (P for trend=0.04) and lower risks of 26% for caffeinated coffee (P for trend<0.001), 16% for decaffeinated coffee (P for trend=0.01), 11% for tea (P for trend=0.02), 31%-33% for wine (P for trend<0.005), 41% for beer (P for trend<0.001), and 12% for orange juice (P for trend=0.004). Consumption of sugar-sweetened soda and punch is associated with a higher risk of stone formation, whereas consumption of coffee, tea, beer, wine, and orange juice is associated with a lower risk.

Do Canadians meet Canada's Food Guide's recommendations for fruits and vegetables?

National dietary guidelines pertaining to the intake of fruits and vegetables (FV) were recently amended, in both Canada and the United States, to provide specific recommendations about dark green and orange vegetables and juice consumption. However, little is known about the extent to which Canadians meet the updated recommendations for FV. This study fills current gaps by applying the National Cancer Institute's methodology for assessing the distribution of usual intake of foods to examine reported FV intake using 24-h recalls from the 2004 Canadian Community Health Survey, cycle 2.2, a nationally representative health survey. After identifying plausible respondents, usual intake distributions were estimated after adjustment for respondents' age, sex, body mass index, frequency of FV consumption, sequence effect, weekend-weekday effect, income, and ethnicity. The majority of Canadians did not meet Health Canada's 2007 recommendations for FV intake. Only 26% of the population aged 2 years and older consumed the minimum number of daily servings recommended for their respective age-sex group. Approximately 1 in 5 Canadians consumed at least 1 daily serving of dark green vegetables, and 9% consumed 1 or more daily servings of orange vegetables or their substitutes. Juice was a substantial contributor to FV intake, particularly for children and teens who, on average, consumed 32%-41% of their daily FV servings as juice. These findings provide insight into the quantity and composition of FV intake and adherence to national dietary recommendations in Canada.

Orange Juice, a Marker of Diet Quality, Contributes to Essential Micronutrient and Antioxidant Intakes in the United States Population

To evaluate the impact of 100% orange juice (OJ) on the healthy diet and micronutrient intakes of the United States population. Cross-sectional study of 13,971 people in the United States aged ≥ 4 years using 2 24-hour diet recalls from the National Health and Nutrition Examination Survey, 2003-2006. Consumption of OJ was higher among 4- to 8-year-old children, older adults (> 50 y old), non-Hispanic blacks, those with lower body mass index, those of lower income level, nonsmokers, dietary supplement users, and those participating in regular exercise (P < .05). Consumption of OJ was positively associated with the percentage of participants meeting MyPyramid recommendations for fruit consumption. Increased OJ consumption was correlated with increased daily intakes of certain micronutrients and antioxidants (P < .05). Percentages of participants with intakes below Estimated Average Requirements for these micronutrients decreased with increased OJ consumption (P < .001). The implicated nutritional and potential health benefits of OJ warrant further investigation in clinical research studies.

Anti-inflammatory Properties of Orange Juice: Possible Favorable Molecular and Metabolic Effects

The low-grade inflammation has been recognized as the link between adiposity and the risk of chronic metabolic disorders. Thus, increased concentrations of inflammatory markers, such as interleukins and tumor necrosis factor alpha have been found in obese individuals. In turn, diet can positively or negatively influence on the risk of chronic metabolic diseases by modulating the inflammatory status. In this context, orange juice consumption can play a role in modulation of inflammatory markers through bioactive compounds, such as the flavonoids (hesperidin, naringenin). According to this review, orange juice appears to mediate the inflammatory response in plasma level and gene expression, and in postprandial and chronic (≥7 consecutive days) periods. The current findings suggest that orange juice could be a dietary feature for prevention and treatment of chronic diseases, although more studies are necessary to evaluate the physiological and molecular mechanisms involved.

100% orange juice consumption is associated with better diet quality, improved nutrient adequacy, decreased risk for obesity, and improved biomarkers of health in adults: National Health and Nutrition Examination Survey, 2003-2006.

BackgroundConsumption of 100% orange juice (OJ) has been positively associated with nutrient adequacy and diet quality, with no increased risk of overweight/obesity in children; however, no one has examined these factors in adults. The purpose of this study was to examine the association of 100% OJ consumption with nutrient adequacy, diet quality, and risk factors for metabolic syndrome (MetS) in a nationally representative sample of adults.MethodsData from adults 19+ years of age (n = 8,861) participating in the National Health and Nutrition Examination Survey 2003-2006 were used. The National Cancer Institute method was used to estimate the usual intake (UI) of 100% OJ consumption, selected nutrients, and food groups. Percentages of the population below the Estimated Average Requirement (EAR) or above the Adequate Intake (AI) were determined. Diet quality was measured by the Healthy Eating Index-2005 (HEI-2005). Covariate adjusted logistic regression was used to determine if consumers had a lower odds ratio of being overweight or obese or having risk factors of MetS or MetS.ResultsUsual per capita intake of 100% OJ was 50.3 ml/d. Among consumers (n = 2,310; 23.8%), UI was 210.0 ml/d. Compared to non-consumers, consumers had a higher (p < 0.05) percentage (% ± SE) of the population meeting the EAR for vitamin A (39.7 ± 2.5 vs 54.0 ± 1.2), vitamin C (0.0 ± 0.0 vs 59.0 ± 1.4), folate (5.8 ± 0.7 vs 15.1 ± 0.9), and magnesium (51.6 ± 1.6 vs 63.7 ± 1.2). Consumers were also more likely to be above the AI for potassium (4.1 ± 0.8 vs 1.8 ± 0.2). HEI-2005 was significantly (p < 0.05) higher in consumers (55.0 ± 0.4 vs 49.7 ± 0.3). Consumers also had higher intakes of total fruit, fruit juice, whole fruit, and whole grain. Consumers had a lower (p < 0.05) mean body mass index (27.6 ± 0.2 vs 28.5 ± 0.1), total cholesterol levels (197.6 ± 1.2 vs 200.8 ± 0.75 mg/dL), and low density lipoprotein-cholesterol levels (112.5 ± 1.4 vs 116.7 ± 0.93 mg/dL). Finally, compared to non-consumers of 100% OJ, consumers were 21% less likely to be obese and male consumers were 36% less likely to have MetS.ConclusionThe results suggest that moderate consumption of 100% OJ should be encouraged to help individuals meet the USDA daily recommendation for fruit intake and as a component of a healthy diet.

A Single-Nucleotide Polymorphism in CYP2B6 Leads to &gt;3-Fold Increases in Efavirenz Concentrations in Plasma and Hair Among HIV-Infected Women

Efavirenz exhibits marked interindividual variability in plasma levels and toxicities. Prior pharmacogenetic studies usually measure exposure via single plasma levels, examine limited numbers of polymorphisms, and rarely model multiple contributors. We analyzed numerous genetic and nongenetic factors impacting short-term and long-term exposure in a large heterogeneous population of human immunodeficiency virus (HIV)-infected women. We performed 24-hour intensive pharmacokinetic studies in 111 women receiving efavirenz under actual-use conditions and calculated the area-under-the-concentration-time curve (AUC) to assess short-term exposure; the efavirenz concentration in hair was measured to estimate long-term exposure. A total of 182 single-nucleotide polymorphisms (SNPs) and 45 haplotypes in 9 genes were analyzed in relationship to exposure by use of multivariate models that included a number of nongenetic factors. Efavirenz AUCs increased 1.26-fold per doubling of the alanine aminotransferase level and 1.23-fold with orange and/or orange juice consumption. Individuals with the CYP2B6 516TT genotype displayed 3.5-fold increases in AUCs and 3.2-fold increases in hair concentrations, compared with individuals with the TG/GG genotype. Another SNP in CYP2B6 (983TT) and a p-glycoprotein haplotype affected AUCs without substantially altering long-term exposure. This comprehensive pharmacogenomics study showed that individuals with the CYP2B6 516TT genotype displayed >3-fold increases in both short-term and long-term efavirenz exposure, signifying durable effects. Pharmacogenetic testing combined with monitoring of hair levels may improve efavirenz outcomes and reduce toxicities.

Effects of red orange juice intake on endothelial function and inflammatory markers in adult subjects with increased cardiovascular risk

Oxidative and inflammatory stresses are involved in the pathogenesis of atherosclerosis. The consumption of fruit and vegetables is associated with improved health and reduced cardiovascular risk. Red oranges have a high content of antioxidant and antiinflammatory substances, but there is a paucity of data concerning their effects on cardiovascular biomarkers in subjects with increased cardiovascular risk. We investigated the effect of red orange juice intake on endothelial function, oxidative stress, and markers of inflammation in subjects with increased cardiovascular risk. Nineteen nondiabetic subjects with increased cardiovascular risk (aged 27-56 y) were included in a randomized, placebo-controlled, single-blind crossover study and compared with 12 healthy, nonobese control subjects. In 2 periods of 7 d each with a 3-d interval, each participant alternatively received 500 mL red orange juice/d and 500 mL placebo/d in a random sequence. All measurements were performed in the morning after overnight fasting. Endothelial function, which was measured as flow-mediated dilation, significantly improved and was normalized (5.7% compared with 7.9%; P < 0.005) after 1 wk of red orange juice consumption. Similarly, concentrations of high-sensitivity C-reactive protein, IL-6, and TNF-α significantly decreased (P < 0.001). Red orange juice had no significant effect on nitric oxide plasma concentrations. A 7-d consumption of red orange juice ameliorates endothelial function and reduces inflammation in nondiabetic subjects with increased cardiovascular risk. This trial was registered at biomedcentral.com as ISRCTN39987296.

The entanglement of consumer expectations and (eco) innovation sequences: the case of orange juice

Prospects for future innovation to reduce the carbon intensity of everyday consumer products rest significantly on the path dependent processes that have caused current products with their associated modes of provision and practices of consumption to be as they are. We use the history of orange juice to examine the dynamics of innovation sequences that have emerged to solve a series of ‘problems’ associated with the production and consumption of orange juice, the latest being the carbon problem. In particular, we focus on the interdependencies between consumer expectations of what constitutes ‘good orange juice’, changes in the product itself and in the system through which it is provisioned. We conclude with a discussion of how historical, path dependent processes lead to alternative framings of the new problem to be solved and different strategies for pursuing innovative solutions.

Orange juice consumption is associated with enhanced antioxidant intake status in the U.S. population: a cross‐sectional study

Antioxidants, including polyphenolic antioxidants, are important to reduce oxidative stress and inflammation, key mechanisms in the development and progression of chronic diseases. The aim of the study was to evaluate the impact of 100% orange juice (OJ) on diet quality and antioxidant intake status of 13,971 U.S. population aged ≥ 4 y in the NHANES 2003–2006. OJ was found to be the largest single contributor to fruit intake and 3rd largest contributor to total antioxidant intake (TAC) in the US, with tea #1 and vitamin C supplements #2. Furthermore, OJ consumers (OJC) had a healthier life style as well as greater intakes of whole fruits and vegetables than non‐OJ consumers (OJNC). OJC had higher intakes of carotenoids, vitamin C, and flavonoids compared to OJNC after adjusting for age, gender, ethnicity, and energy intake (p&lt;0.01). Particularly, the intakes of β‐cryptoxanthin, hesperidins, and naringenins were increased by the amount of OJ consumption (p&lt;0.001). Dietary TAC also showed similar increases relative to OJ consumed compared to NOJC (p&lt;0.001). Overall, OJC have higher antioxidant intakes and greater intakes of fruit than OJNC.

Multi‐nutrient fortified juices improve vitamin D and vitamin E status in children

We examined whether children consuming orange juice (OJ) fortified with calcium (Ca) and combinations of vitamins D, E and A could increase serum 25‐hydroxyvitamin D [25(OH)D], alpha‐tocopherol, and retinol levels. Boys and girls (6 to 12 yr) were recruited (n=179) and randomized into 3 groups: CaD (700 mg Ca+ 200 IU vitamin D), CaDEA (700 mg Ca + 200 IU vitamin D + 12 IU vitamin E + 2000 IU vitamin A as beta‐carotene), or Ca (700 mg Ca). Children consumed two 240 mL glasses of CaD, CaDEA, or Ca OJ for 12 weeks. We hypothesized the mean increase of 25(OH)D would be 1 SD higher in children consuming vitamin D fortified juice. Multivariate models and repeated measures of ANOVA tested for group differences. Baseline 25(OH)D was 27.4 ± 11.1 ng/mL with 26.2% deficient (≤ 20 ng/mL). The 25(OH)D increase in the CaD group was greater than the Ca group (P = 0.029). The increase in alpha‐tocopherol in the CaDEA group was greater than the Ca or CaD groups (P &lt; 0.001). Retinol levels were not increased. Daily consumption of OJ providing 700 mg Ca and 200 IU of vitamin D improved 25(OH)D levels and provision of 12 IU vitamin E increased alpha‐tocopherol levels in children without gaining undesirable weight greater than expected growth changes.

Impact of orange juice consumption on macronutrient and energy intakes and body composition in the US population.

The present study evaluated the contribution of 100 % orange juice (OJ) consumption to the intakes of macronutrients and energy and its impact on body composition. A cross-sectional study was conducted. The main exposure was OJ consumption based on two non-consecutive 24 h diet recalls. Macronutrient and energy intakes and body composition parameters were outcome measures. All statistical analyses were carried out using SAS and SUDAAN statistical software packages to allow for multistage sample designs. The US population and its subgroups. The US population aged ≥4 years (n 13 971) from the National Health and Nutrition Examination Survey 2003-2006, conducted by the National Center for Health Statistics. In this US population, OJ consumers had lower BMI and healthier lifestyle behaviours (including lower alcohol consumption and smoking as well as higher exercise level) than non-consumers (P < 0.05). After adjusting for covariates, OJ consumers had higher daily intakes of carbohydrate, total sugar, total fat and energy than non-consumers (P < 0.01). However, these linear trends still remained even after OJ was removed from the food list of items consumed. Adult OJ consumers had lower BMI, waist circumference and percentage body fat than non-consumers (P < 0.01), as well as lower odds ratio for overweight and obesity (P < 0.01). These effects were not seen in children and adolescents, where there was no significant difference in BMI, waist circumference and percentage body fat in OJ consumers compared with non-consumers. OJ consumption was associated with healthier body composition in adults; while there were no significant associations between OJ consumption and body composition in children and adolescents.
