Effect of Fibre-Enriched Orange Juice on Postprandial Glycaemic Response and Satiety in Healthy Individuals: An Acute, Randomised, Placebo-Controlled, Double-Blind, Crossover Study.

Background: Consumption of fibre-enriched orange juice may be an appropriate way to supplement daily fibre intake and achieve beneficial effects on metabolic health. The present study aimed to assess the short-term effects of fibre-enriched orange juice on postprandial metabolism and satiety in a healthy adult population. Methods: In this double-blind, randomised, placebo-controlled, crossover study 10 healthy subjects underwent two one-day trials in which they consumed an orange juice beverage containing 1.4 g/100 mL of citrus fibre (29.3% soluble and 41.9% insoluble) or a placebo (regular orange juice without added fibre). Postprandial glucose, insulin, gut hormones (GLP1, GIP and ghrelin), leptin and qualitative appetite/satiety assessment were measured every 15 or 30 min over the 120 min test period. Results: The fibre-enriched orange juice decreased postprandial serum glucose and circulating insulin levels at 15 min compared with the placebo. In addition, after intake of the fibre-enriched juice, a significant effect on qualitative feelings of satiety and fullness was observed at 15 and 120 min, and was accompanied by a significant decrease in GLP1 response at 15 min. No significant changes were observed in leptin, GIP and ghrelin after juice intake. Conclusions: In healthy individuals, a single acute consumption of fibre-enriched orange juice has short-term beneficial effects on postprandial glycaemia, circulating insulin levels and satiety through GLP1 secretion.

Associations between 100% Orange Juice Consumption and Dietary, Lifestyle and Anthropometric Characteristics in a Cross-Sectional Study of U.S. Children and Adolescents.

Concerns about orange juice’s sugar content have spurred discussions regarding its potential contributions to childhood obesity. The objective of this study was to evaluate the association between 100% orange juice (OJ) consumption and dietary, lifestyle and anthropometric characteristics in children and adolescents. Baseline anthropometric, dietary and lifestyle data from the Growing Up Today Study I (GUTS I) and GUTS II were collected via self-reported questionnaires from 26,554 participants. The mean values of these variables were then computed for children grouped by categories of OJ consumption, and linear trend testing was used to determine whether OJ consumption was linearly related to these variables. Multivariate adjustment modeling was used to calculate odds ratios of being obese or overweight/obese by OJ consumption. Among both boys and girls, OJ intake was positively associated with height, height-for-age z-score (HAZ), intakes of total energy, total energy excluding OJ, fruits and non-starchy vegetables and physical activity. BMI, BMI z-score and BMI-for-age percentile did not differ by OJ consumption. After adjustment for cohort, age, race, total energy intake without OJ, physical activity and screen time, prevalence of overweight/obesity significantly decreased by OJ intake in boys compared to non-consumers (odds ratio (OR) and 95% confidence interval (CI)): 1.17 (1.02, 1.33) for 1–3 glasses per month, 1.11 (0.98, 1.26) for 1–6 glasses per week, 1.00 (0.85, 1.18) for 1 glass per day, 0.91 (0.73, 1.13) for ≥1 glass per day, p-trend = 0.0403). Prevalence of obesity similarly decreased by OJ intake in boys. Prevalence of overweight/obesity and obesity did not significantly differ by OJ intake in girls. The results indicate that children consuming more OJ tended to practice healthier dietary and lifestyle habits without increased prevalence or odds of obesity or overweight.

Why the new orange juice consumption model favors global trade and growth in orange production

PurposeThe purpose of this paper is to analyze international orange trade as different types of orange juice seem to obtain the favor of newer food consumption patterns as opposed to fresh oranges. In addition, the authors will outline market tendencies that could be useful to stakeholders interested in any way in the sector.Design/methodology/approachThis document uses the Lafay index (LFI) in order to evaluate the intra-sectoral trade specialization; however, the social network analysis (SNA) approach is used to connect the international trade relations and to refine, classify and prioritize the countries having a central role in the orange juice world trade network. For both indexes, UNCOMTRADE has been used.FindingsThe findings show that the growing orange juice trade is the leading global growth factor as opposed to the sale of fresh oranges. It appears that major trade revenues come from orange juice concentrate (Frozen Concentrated Orange Juice (FCOJ)). Business takes place mostly in Europe.Originality/valueThis study shows for the first time that the current orange juice export competitiveness is crucial to the long-term survival of the orange sector. This study valuably contributes to the less known literature regarding FCOJ and Not From Concentrate orange juice trade relevance.

Daily Consumption of Orange Juice from Citrus sinensis L. Osbeck cv. Cara Cara and cv. Bahia Differently Affects Gut Microbiota Profiling as Unveiled by an Integrated Meta-Omics Approach.

We have investigated the effect of intake of two different orange juices from Citrus sinensis cv. "Cara Cara" and cv. "Bahia" on faecal microbiota and metabolome using an integrated meta-omics approach. Following a randomized crossover design, healthy subjects daily consumed 500 mL of orange juice from Cara Cara or Bahia juices or an isocaloric control drink. Stools were collected at baseline (T0) and after a week (T7) of intervention. Operational taxonomic units (OTUs) were pyrosequenced targeting 16S rRNA, and faecal metabolites were analyzed by an untargeted metabolomics approach based on 1H NMR spectroscopy. The major shift observed in microbiota composition after orange juice intake was the increased abundance of a network of Clostridia OTUs from Mogibacteriaceae, Tissierellaceae, Veillonellaceae, Odoribacteraceae, and Ruminococcaceae families, whose members were differently affected by Cara Cara or Bahia juice consumption. A core of six metabolites such as inositol, choline, lysine, arginine, urocanic acid, and formate significantly increased in Cara Cara compared to the Bahia group.

Effect of orange juice and tryptamine on the behavior and c-fos expression of Wistar rats.

Recent reports have shown that commercial orange juice is rich in biogenic amines. Consumption of foods containing large amounts of biogenic amines increase hypertensive crisis and high levels of histamine and tyramine, which have been implicated as causative agents in a number of food poisoning episodes. In addition, accumulation of tryptamine in plasma may be associated with mood disorders. The aim of this study was to determine whether chronic administration of orange juice extract and tryptamine affects the behavior and c-fos expression in the rat. For this purpose, Wistar male rats were injected with saline solution, tryptamine or orange juice extract. Sucrose preference test and elevated plus maze were evaluated to determine hedonic and anxiety behavior, respectively. Rats treated with orange juice extract showed increased anxiety behavior and sucrose consumption, similar to those treated with tryptamine. In addition, dorsal raphe nucleus, accumbens nucleus, and hippocampus showed an increase of c-fos positive cells in rats treated with orange juice extract. In conclusion, the chronic and lengthy consumption of orange juice or their derivatives in the diet could be a factor responsible to induce mood disorders and may promote excess caloric consumption.

Blond and blood juice supplementation in high fat diet fed mice: effect on antioxidant status and DDAH/ADMA pathway.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease spread throughout the world. The most frequent causes of death in NAFLD patients are due both to liver and cardiovascular damage. Several pathways, including the dimethylarginine dimethylaminohydrolase (DDAH)/asymmetric dimethylarginine (ADMA) pathway, are involved in the pathogenesis of NAFLD. It has been reported that ADMA plasmatic levels are increased in patients with hepatic dysfunction such as NAFLD. Although many studies demonstrated that some foods are effective in the treatment of NAFLD, few studies have evaluated their effects with respect to the prevention of the disease. It has been reported that sweet orange juice (OJ) consumption may be associated with potential health benefits. However, some varieties of sweet orange are more effective than others. The aim of the present paper was to investigate the effect of blond and blood sweet orange juice in prevention of NAFLD by evaluating its ability to improve liver steatosis in mice with diet-induced obesity, reducing oxidative stress and affecting the DDAH/ADMA pathway. Results obtained in our experimental conditions evidenced that blood orange juice rather than blond orange juice was more effective. Blood orange juice or blond orange juice enriched in anthocyanins may represent a promising dietary option for the prevention of fatty liver disease.

Assessing key factors influencing orange juice demand in the current US market

AbstractThe US orange juice (OJ) industry has experienced dramatic changes and pressure from both the supply and demand side in the past decade. It is critical for the industry to understand and enhance consumer's demand to sustain the higher prices associated with decreased production and maintain demand for the point in time where production can recover. This study utilized both Nielsen scanner data and a unique consumer tracker database to explore the impact of key factors on OJ consumption to estimate the return on investment. The usage of two datasets and multiple methods increases the reliability of results. Our results identified several demand drivers including demographics, health conditions, promotion awareness, and consumer's positive perceptions. Moreover, this study implies that a larger positive impact can be obtained by focusing on the positive aspects over responding to negative news. Therefore, we suggest the industry enhance generic promotion and advertising awareness and develop marketing programs that emphasize the positive attributes and benefits of OJ.

Long-term intake of vegetables and fruits and subjective cognitive function in US men.

To evaluate the prospective association of long-term intake of vegetables and fruits with late-life subjective cognitive function (SCF). Among 27,842 men with a mean age of 51 years in 1986, we used multinomial logistic regression to examine the relation of vegetable and fruit consumption to future SCF. Average dietary intake was calculated from 5 repeated food frequency questionnaires collected every 4 years until 2002. SCF score was assessed twice (2008 and 2012) using a 6-item questionnaire; validity was supported by strong associations with APO ε4 genotype. We categorized the average of the 2 scores as good, moderate, and poor SCF. Higher intakes of total vegetables, total fruits, and fruit juice were each significantly associated with lower odds of moderate or poor SCF after controlling for major nondietary factors and total energy intake. The association with total fruit intake was weaker after further adjusting for major dietary factors. In this model, the multivariate odds ratios (95% confidence intervals) for vegetable intake (top vs bottom quintile) were 0.83 (0.76-0.92), p trend <0.001 for moderate SCF and 0.66 (0.55-0.80), p trend <0.001 for poor SCF. For orange juice, compared to <1 serving/mo of intake, daily consumption was associated with a substantially lower odds of poor SCF (0.53 [0.43-0.67], p trend <0.001). Higher consumption of vegetables and fruits 18 to 22 years before SCF assessment was associated with lower odds of poor SCF independent of more proximal intake. Our findings support a long-term beneficial role of vegetable, fruit, and orange juice consumption on SCF.

A critical evaluation of the use of gas chromatography- and high performance liquid chromatography-mass spectrometry techniques for the analysis of microbial metabolites in human urine after consumption of orange juice

The present study compared and validated two analytical methods, HPLC-HRMS, and GC–MS using MSTFA as derivatization agent, for the analysis of microbiota-derived phenolic acids and aromatic compounds accumulating in urine, collected over a 24 h period after the consumption of 500 mL of orange juice. In addition, purification procedures using SDB-L and HLB solid phase cartridges were compared when HPLC-HRMS technique was used. Both HPLC-HRMS and GC–MS methodologies were successfully validated in terms of specificity, sensitivity, limit of detection and quantification, recovery and matrix effects. HPLC-HRMS, unlike GC–MS, does not require sample derivatization prior to analysis. GC–MS was not suitable for the analysis of phenolic sulfate and glucuronide metabolites because of their lack of volatility. These phase II metabolites could, however, be analysed by HPLC-HRMS which, as a consequence, provided more detailed and complete information on the phenolic compounds derived from microbiota-mediated degradation of orange juice (poly)phenols. Furthermore, the use of SDB-L and HLB cartridges for sample purification prior to HPLC-HRMS analysis is suitable for free phenolics and glucuronide metabolites but not sulfate derivatives. These findings highlight that the use of an inappropriate analytical protocol can adversely affect studies on the bioavailability of dietary (poly)phenols in which microbiota-derived phenolic catabolites play an important role.

Assessing the impact of immersing teeth in fresh orange juice and commercial orange juice on enamel hardness: an in vitro study

The pH of orange juice is below the critical pH of the enamel. Lately, consumption of orange juice has considerably increased because of its commercial availability. This study aims to investigate the impact of immersion time and juice types, both fresh and packaged, on enamel hardness. 60 premolars were immersed in fresh orange juice (n = 30) and commercial juice (n = 30) for 30 and 60 min and assessed the obtained data using repeated analysis of variance, Friedman test, Mann–Whitney U-test, and independent t-test. Enamel hardness decreased (P < 0.05) at every assessed time, and the commercial juice immersion significantly decreased the enamel hardness (P < 0.05). This study infers that enamel hardness is adversely affected by the pH, citric acid concentration, and immersion time of the orange juice.

High orange juice consumption with or in-between three meals a day differently affects energy balance in healthy subjects

Sugar-containing beverages like orange juice can be a risk factor for obesity and type 2 diabetes although the underlying mechanisms are less clear. We aimed to investigate if intake of orange juice with or in-between meals differently affects energy balance or metabolic risk. Twenty-six healthy adults (24.7 ± 3.2 y; BMI 23.2 ± 3.2 kg/m2) participated in a 4-week cross-over intervention and consumed orange juice (20% of energy requirement) either together with 3 meals/d (WM) or in-between 3 meals/d (BM) at ad libitum energy intake. Basal and postprandial insulin sensitivity (primary outcome), daylong glycaemia, glucose variability and insulin secretion were assessed. Body fat mass was measured by air-displacement plethysmography. After BM-intervention, fat mass increased (+1.0 ± 1.8 kg; p < 0.05) and postprandial insulin sensitivity tended to decrease (ΔMatsudaISI: −0.89 ± 2.3; p = 0.06). By contrast, after WM-intervention fat mass and gamma-glutamyl transferase (GGT) decreased (−0.30 ± 0.65 kg; −2.50 ± 3.94; both p < 0.05), whereas glucose variability was higher (ΔMAGE: +0.45 ± 0.59, p < 0.05). Daylong glycaemia, insulin secretion, changes in basal insulin sensitivity, and triglycerides did not differ between WM- and BM-interventions (all p > 0.05). In young healthy adults, a conventional 3-meal structure with orange juice consumed together with meals had a favorable impact on energy balance, whereas juice consumption in-between meals may contribute to a gain in body fat and adverse metabolic effects.

β-Cryptoxanthin is more bioavailable in humans from fermented orange juice than from orange juice

Carotenoids, especially β-cryptoxanthin, exert multiple biological activities in the organism. Various processing techniques can improve carotenoid bioavailability in relation to the food matrix. The study objective was to compare the bioavailability of carotenoids from orange juice (OJ) with that from a beverage obtained by alcoholic fermentation of orange juice (FOB). Seven volunteers were recruited for a randomized, controlled, and crossover study. Post-intake plasma carotenoid concentrations were measured by HPLC in the subjects at 0–8 h after their consumption of OJ or FOB. β-Cryptoxanthin and lutein absorption was significantly higher from FOB than from OJ, but no significant difference in zeaxanthin absorption was found. The mean baseline-corrected area under the concentration curve (AUC0-8 h) for β-cryptoxanthin, lutein and zeaxanthin was 24.6-, 1.3- and 4.65-fold larger, respectively, after FOB versus OJ consumption. This fermented orange beverage could be an abundant source of bioavailable carotenoids, and its regular consumption may exert healthy effects.

Orange juice affects acylcarnitine metabolism in healthy volunteers as revealed by a mass-spectrometry based metabolomics approach

Citrus juices, especially orange juice, constitute rich sources of bioactive compounds with a wide range of health-promoting activities. Data from epidemiological and in vitro studies suggest that orange juice (OJ) may have a positive impact on lipid metabolism. However, the effect of orange juice intake on blood lipid profile is still poorly understood.We have used two different blood samples, Dried Blood Spots (DBS) and plasma, to assess the effect of two-week orange juice consumption in healthy volunteers by a mass-spectrometry based metabolomics approach. DBS were analysed by liquid chromatography mass spectrometry (LC-MS) and plasma samples were analysed by the gas chromatography mass spectrometry (GC–MS).One hundred sixty-nine lipids including acylcarnitines (AC), lysophosphatidylcholines (LysoPC), (diacyl- and acyl-alkyl-) phosphatidylcholines (PC aa and PC ae) and sphingomyelins (SM) were identified and quantified in DBS. Eighteen fatty acids were identified and quantified in plasma. Multivariate analysis allowed to identify an increase in C3:1, C5-DC(C6-OH), C5-M-DC, C5:1-DC, C8, C12-DC, lysoPC18:3, myristic acid, pentadecanoic acid, palmitoleic and palmitic acid and a decrease in nervonic acid, C0, C2, C10, C10:1, C16:1, C16-OH, C16:1-OH, C18-OH, PC aa C40:4, PC ae C38:4, PC ae C42:3, PC ae C42:4 and cholesterol levels after orange juice intake.A two-week period of orange juice intake could affect fatty acids β-oxidation through mitochondrial and peroxisomal pathways, leading to an increase of short-chain acylcarnitines and a decrease of medium and long-chain acylcarnitines. This is the first report analyzing the effect of orange juice intake in healthy volunteers using a dried blood spot-based metabolomics approach.

The effect of CPP-ACP paste on the surface hardness of glass ionomer cement when immersed in orange juice

This study aims to identify the effect of CPP-ACP paste on the surface hardness of glass ionomer cement (GIC) when immersed in orange juice. Eighteen specimens of Fuji IX GIC were divided into three groups: no CPP-ACP added (group A); CPP-ACP applied for three minutes (group B); and CPP-ACP applied for 30 minutes (group C). Specimens were immersed in orange juice and tested for surface hardness using a Vickers hardness tester. Data were analyzed using the one-way ANOVA (p = <0.05). Group A resulted in a 31.77 ± 0.77 Vickers Hardness Number (VHN), group B in a 42.97 ± 1.08 VHN, and group C in a 51.92 ± 0.27 VHN. It was concluded that application of CPP-ACP paste for 30 minutes is effective in preventing a decrease in the surface hardness of GIC due to orange juice consumption.

In situ evaluation of color stability and hardness' decrease of resin-based composites.

To determine the color stability (CS) and hardness' decrease (HD) of two commercial resin-based composites (RBCs), after in situ staining conditions (SC). Six disc-shaped specimens (6 × 2 mm) of two RBCs-Filtek Z350 XT (FZX) and IPS Empress Direct (IED)-were randomly distributed into palatal devices. Eight volunteers (aged 20-30 years) participated in this study. The in situ SC consisted of 400 mL consumption (2 × 200 mL/day) of water, orange juice, cola soda, and coffee and 140mL consumption of red wine, 10 days each. CS was obtained by CIELAB color difference (ΔE*) and HD (in %) by the Knoop method (50 g for 15 s), after curing (baseline) and after the in situ SC. Data were statistically analyzed at α = 0.05 significance level. For both RBCs, the coffee (5.7 ± 0.5 for FZX; 5.9 ± 1.3 for IED) and red wine (6.1 ± 1.1 for FZX; 6.2 ± 1.6 for IED) groups showed the highest ΔE* while water the lowest (1.6 ± 0.6 for FZX; 1.8 ± 0.2 for IED). The highest HD was induced by red wine group for FZX (40.7 ± 5.4) and by cola soda for IED (40.6 ± 3.2) while the water groups (8.3 ± 1.7 for FZX; 7.8 ± 2.1 for IED) presented the lowest values for both RBCs. Both RBCs were affected by the in situ SC, but no significant differences for CS and HD were observed between them. Red wine and coffee showed higher discoloration potential. This in situ study suggests that color stability and hardness' decrease of resin-based composites were dependent on the type of consumed beverage and materials' composition. Patients with esthetic direct restorations should be aware of the degradative potential of them.

Urinary metabolite profiling of flavonoids in Chinese volunteers after consumption of orange juice by UFLC-Q-TOF-MS/MS.

The metabolism of flavonoids derived from orange juice in Chinese volunteers has not been well investigated. With the ultra-fast liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UFLC-Q-TOF-MS/MS) system, orange juice-derived flavonoids, as well as metabolites contained in urine collected from healthy Chinese volunteers after consumption of 250mL orange juice, were systematically identified and quantified. Finally, a total of 9 flavonoids and 30 metabolites were detected. Obtained results revealed that flavonoids derived from orange juice underwent extensive phase II metabolism in human, mainly comprising glucuronidation and sulfation. The overall recovery of the primary flavonoid aglycones, i.e., naringenin and hesperetin, were both approximately equivalent 22% of intake, primarily occurred in 4-12h post consumption. Meanwhile, additional 35 phenolic catabolites were identified in urine collected post consumption. However, it is difficult to determine the exact amounts of phenolic catabolites derived from specific flavonoid due to the interference of diets and other flavonoids. This work would be valuable for the clarification of metabolic profiles for flavonoids in Chinese population.
