EFFECTIVENESS OF FRUIT JUICE AS COMPLEMENTARY THERAPY ON BLOOD PRESSURE OF HYPERTENSION PATIENTS : A SYSTEMATIC REVIEW OF RANDOMIZED CONTROLLED TRIALS

Hypertension treatment can be helped through complementary therapies, one of which is fruit juices. This study aimed to systematically review the evidence from various study regarding the effect of fruit juices on blood pressure in hypertensive patients and the types of fruit juices that are proven to be effective in reducing hypertension.This study is systematic review. Literature searching was conducted in four electronic databases, namely CINAHL, EMBASE, Pubmed, and Sciencedirect with the phrase fruit juices AND (hypertension OR blood pressure). Studies obtained from searching will be selected based on a screening title and abstract, eligibility criteria, and assesment risk of bias. The results of the study obtained 21 final studies with RCT research designs that passed the screening with complete eligibility criteria. However, the studies with valid results only amounted to 8 studies. These data show that as many as 5 studies prove fruit juices can reduce blood pressure in hypertensive patients and 3 other studies have stated the opposite. Thus, it can be concluded that there is strong evidence that fruit juices has a significant effect on reducing blood pressure in hypertensive patients. Fruit juices that have been shown to be effective are orange juice and queen garnet plum juice

Effect of fruit juices in skim milk extender in maintaining Sapudi ram spermatozoa quality at chilled temperature

This study aimed to determine the effect of the addition of cherry tomato, california papaya, and honey melon juice into skim milk extender in maintaining the quality of Sapudi ram semen at chilled temperature (5oC) storage. Five replication of ejaculates were divided equally into four groups. In control group (T0) semen was diluted in skim milk extender, while in T1, T2, and T3 groups semen were diluted in skim milk extender contained 20% of cherry tomato, california papaya, and honey melon juice, respectively. The extended semen was stored at a chilled temperature, and semen quality (based on sperm motility, viability, and plasma membrane integrity) was observed daily for five days. The result showed that semen quality declined day by day during the five days of storage. Based on the minimum standard of post-thawed semen motility (40%), the spermatozoa of the control group only lasted by the second day. Meanwhile, in the groups with the addition of fruit juice motility could last up to the third day, with the highest motility (p <0.05) on the addition of california papaya juice. This study concluded that the addition of 20% (v/v) california papaya juice in skim milk extender could maintain the percentage of spermatozoa motility up to three days at a chilled temperature.

Application of Design of Experiments to the Analysis of Fruit Juice Deacidification Using Electrodialysis with Monopolar Membranes.

Despite the beneficial health effects of fruit juices, the high content of organic acids and low pH of some of them limit their consumption. The aim of this work was to study the deacidification of fruit juices using electrodialysis (ED) with monopolar membranes. Aqueous solutions of citric acid were used in ED deacidification experiments following a factorial design with citric acid concentration and electric current varying in the ranges of 5–25 g/L and 0.5–1 A, respectively. The design runs were characterized by a constant Faraday efficiency of 0.37 ± 0.03, suggesting that the triple-charged citrate ion (Cit3−) carried the electric charge through the anionic membranes. During deacidification, the pH increased in agreement with the decreasing concentration of the acid. Deacidification of pineapple juice or pineapple juice enriched with 20 g/L of citric acid using ED led to similar values of the Faraday efficiency, confirming that Cit3− is the main ion migrating through the anionic membrane. However, the decrease in titratable acidity during ED treatment was accompanied by a decrease in pH. Such behavior, already reported, was explained by considering proton generation during the transformation of the single (H2Cit−) and double-charged (HCit2−) citrate ions into the triple-charged ion (Cit3−) when entering the anionic membrane.

Effect of citrus fruit and juice consumption on risk of developing type 2 diabetes: Evidence on polyphenols from epidemiological and intervention studies

BackgroundCitrus fruits are commonly consumed worldwide in both fresh and processed forms, especially as juices. While fruit consumption is perceived as beneficial for long-term health, the effects of fruit juices are more controversial, linked to high intrinsic sugar content. On the other hand, citrus juices, like the fruits, are rich in many nutrients including vitamin C, and also contain various bioactive components such as (poly)phenols. Scope and approachThis review examines the effect of citrus fruits, juices and constituent (poly)phenols on the risk of type 2 diabetes through a critical evaluation of the literature, considering data from epidemiological and human intervention studies, both acutely and chronically. Key findings and conclusionsEpidemiological studies show some protection from consuming citrus fruits against developing type 2 diabetes, but the outcomes for citrus juices are conflicting. The direct acute effect of citrus (poly)phenols on postprandial glycaemic response, a risk factor for type 2 diabetes, is relatively small. Improved fasting glucose, fasting insulin and insulin resistance were observed after longer periods of citrus juice consumption. High inter-individual variation in flavanone bioavailability is possibly one of the main factors affecting the physiological responses in humans, as well as changes in gut microbiota. To further understand the effect of citrus consumption on type 2 diabetes risk and to shed light on the interconnection between the gut microbiome, bioavailability and bioefficacy, future acute and chronic studies linking these factors with clinical outcomes are recommended.

Effect of fruit juices and chloride ions on the corrosion behavior of orthodontic archwire

ABSTRACTElectrochemical and surface analytical study on the corrosion behavior of AISI 316L stainless steel orthodontic archwire in different fruit juices was carried out. The electrochemical parameters were measured after immersing the wires for approx. 24 h in artificial saliva (AS) containing different fruit juices and separately in fruit juices with 1% NaCl in AS. All the fruit juices used in this study increased the rate of corrosion process in AS in the presence or absence of salt. Addition of 1% NaCl to the AS, all experiments exhibited pitting. Solanum lycopersicum (Tomato) and Durio zibethinus (Amra) are rated as most detrimental to the surface followed by Prunus domestica Linn. (Plum) juice. SEM Micrographs of the specimens show formation of blisters onto the steel surface which are remnants of passive film.

Rehydration properties of hybrid method dried fruit enriched by natural components

Abstract The aim of the study was to determine the impact of osmotic pre-dehydration and drying of fruit on the rehydration properties of dried fruit. Herein, the effect of fruit juice, applied as a natural enriching substance was very important. In addition, the properties of dried fruits obtained through combined air-drying and subsequent microwave-vacuum drying with ‘puffing’ effect were similar to the freeze-dried fruits, but showed other rehydration properties. As raw material, frozen strawberry (Honeoye variety) and fresh apples (Idared variety) were used in the study. The apples and partially defrosted strawberries were prior dehydrated in solutions of sucrose and a mixture of sucrose with chokeberry juice concentrate at 50°C for 2 h. Next, the fruit samples were dried by one of two ways: air-drying (50°C, 5 h) and microwavevacuum drying for about 360 s; and freeze-drying (30°C, 63 Pa, 24 h). The rehydration was carried out in distilled water (20°C, 5 h). The osmotic pre-dehydration hindered fruit drying process. The impact of drying method became particularly evident while examining the kinetics of rehydration. During the rehydration of the pre-dehydrated dried fruit a slower hydration could be observed. Freeze-dried strawberries absorbed 2-3 times more water than those dried by the ‘puffing’ effect.

Effect of Fruit Juices and Other Beverages on Loss of Tooth Structure

Objective: To determine the effect of seven different beverages on tooth enamel. Material and Methods: Human teeth samples were immersed in each beverage (Pepsi, Red Bull, Orange juice, Apple juice, Lemon juice, Coffee and Green tea). Specimens were divided into seven groups by beverage type (n = 5 per group). Weight of the enamel was measured before and after immersion in different beverages daily for at periodic intervals of 24hrs, 7 days, 15 days and 30 days. The data were recorded after weighing the teeth at each time. The beverages were replaced daily. Anova and Tukey post hoc test was performed to compare the differences in percent weight loss. The significance level was set at 5%. Results: There was change in the mean percent weight loss amongst the different beverages with orange juice showing a high reduction in comparison to green tea and coffee. The mean weight reduction of orange juice was by 21% followed by Red Bull (13%), Pepsi (11%), Lemon juice (16%), Apple juice (16%), coffee (3%) and green tea (3%). Conclusion: This study shows that different beverages have erosive potential on teeth depending on the duration of the exposure.

Protective effects of fruit-juices on sperm viability of West African Dwarf goat bucks during cryopreservation

The present study was conducted to determine the effects of adding fruit-juices to semen extenders on viability of buck spermatozoa during cryopreservation in two studies. Pooled semen samples obtained from West African Dwarf (WAD) goat bucks were diluted with Tris-egg yolk based extenders. In study I, the diluted semen samples were supplemented with orange ( Citrus sinensis ), cucumber ( Cucumis sativus ) and pineapple ( Ananas comosus ) juices (2.5, 5, 7.5 and 10 ml/100 ml). In study II, the diluted semen samples were supplemented with 5 ml/100 ml of different combinations of fruit-juices consisting of pineapple and orange juices (TEYPO) at a 1:1 ratio, pineapple and cucumber juices (TEYPC) at a 1:1 ratio, orange and cucumber juices (TEYOC) at a 1:1 ratio, and pineapple, orange and cucumber juices (TEYPOC) at a 1:1:1 ratio, respectively. The diluted semen samples were cryopreserved and thereafter evaluated for sperm viability parameters. The extenders supplemented with 7.5 and 10% orange, and 10% pineapple had higher (P < 0.05) motility compared to the control. There was higher (P < 0.05) acrosome integrity in extenders supplemented with orange and pineapple at all levels compared to the control while cucumber at 10% had higher (P < 0.05) acrosome integrity compared to other levels and the control. The extenders supplemented with cucumber, orange and pineapple had higher (P < 0.05) membrane integrity compared to the control except at 7.5% of extender supplemented with cucumber. Similarly, the extenders supplemented with cucumber, orange and pineapple had lower (P < 0.05) sperm abnormality compared to the control. The extenders supplemented with cucumber, orange and pineapple at 2.5, 10 and 7.5% respectively had lower (P < 0.05) concentrations of MDA compared to other levels and the control. There was higher motility and acrosome integrity in extenders supplemented with different combinations of fruit-juices (P < 0.05) compared to the control. TEYPC had higher (P < 0.05) membrane integrity and lower (P < 0.05) concentrations of MDA compared to the control. The findings revealed that extenders supplemented with orange and pineapple at 10% consistently improved motility, acrosome integrity and membrane integrity, and reduced sperm abnormality compared to the control while no particular combination of these fruit-juices was consistently superior in all the parameters.

Effect of fruit juice on glucose control and insulin sensitivity in adults: a meta-analysis of 12 randomized controlled trials.

BackgroundDiabetes mellitus has become a worldwide health problem. Whether fruit juice is beneficial in glycemic control is still inconclusive. This study aimed to synthesize evidence from randomized controlled trials on fruit juice in relationship to glucose control and insulin sensitivity.MethodsA strategic literature search of PubMed, EMBASE, and the Cochrane Library (updated to March, 2014) was performed to retrieve the randomized controlled trials that evaluated the effects of fruit juice on glucose control and insulin sensitivity. Study quality was assessed using the Jadad scale. Weighted mean differences were calculated for net changes in the levels of fasting glucose, fasting insulin, hemoglobin A1c (HbA1c), and homeostatic model assessment of insulin resistance (HOMA-IR) using fixed- or random-effects model. Prespecified subgroup and sensitivity analyses were performed to explore the potential heterogeneity.ResultsTwelve trials comprising a total of 412 subjects were included in the current meta-analysis. The numbers of these studies that reported the data on fasting glucose, fasting insulin, HbA1c and HOMA-IR were 12, 5, 3 and 3, respectively. Fruit juice consumption did not show a significant effect on fasting glucose and insulin concentrations. The net change was 0.79 mg/dL (95% CI: −1.44, 3.02 mg/dL; P = 0.49) for fasting glucose concentrations and −0.74 µIU/ml (95% CI: −2.62, 1.14 µIU/ml; P = 0.44) for fasting insulin concentrations in the fixed-effects model. Subgroup analyses further suggested that the effect of fruit juice on fasting glucose concentrations was not influenced by population region, baseline glucose concentration, duration, type of fruit juice, glycemic index of fruit juice, fruit juice nutrient constitution, total polyphenols dose and Jadad score.ConclusionThis meta-analysis showed that fruit juice may have no overall effect on fasting glucose and insulin concentrations. More RCTs are warranted to further clarify the association between fruit juice and glycemic control.

A comparative study of pH modulation and trace elements of various fruit juices on enamel erosion: An in vitro study

Fruit juices are popular worldwide with children of all ages as they are sweet and perceived to be healthful. This in vitro study was sought to measure pH of 10 different fruit juices, to find out possible erosive effects on human dental enamel of 40 extracted sound premolars and also to measure fluoride and trace elements of these juices. The estimation of pH of fruit juices was done by using Systronic upH 362 pH meter. The erosive effects of fruit juices were tested by using polarized light microscope. Orion electrode was used to measure fluoride. The trace elements were estimated by using Atomic Absorption Spectrophotometer No. 6501F. The pH values in different juices were observed at different levels, and pH values of these juices were more acidic than baseline after 24 hours. As the time increased, the erosion effect became more in pineapple; grape and sugarcane juices, and they had more cariogenic trace elements like selenium, iron and manganese. So, these juices were found to be cariogenic. To conclude, orange, mousambi, mango, pomegranate, apple, chikku and watermelon juices had no erosive effect on the human enamel, with the presence of highest amount of trace elements like fluoride and phosphorous which are considered as strongly cariostatic.

EFFECT OF FRESH FRUIT JUICES ON pH OF DENTAL PLAQUE

Background: The concept of health has prevailed for centuries and the dietary habits are changing with modernization. “Healthy eating” is perceived to be important and fruit juices are promoted aggressively as a “Health drink”. Objectives: 1. To estimate endogenous pH and titratable acidity of four freshly prepared fruit juices. 2. To assess the effect of fruit juices on plaque pH in two groups. (DMFT=0 and DMFT≥ 1) Material and Methods: Forty Volunteers were divided into two groups based on caries experience. Endogenous pH and titratable acidity of fruit juices; pH of plaque samples collected at different time interval was assessed. Statistical analysis was done by using ANOVA and Tukey’s post hoc. Result: Endogenous pH of all fruit juices was acidic. Titratable acidity was maximum for sweet lime. In group B for Mango and Sweet lime plaque pH was below critical value till 30 minutes. Conclusion: All the fruit juices tested in present study were acidic in nature and reduced plaque pH below critical pH in caries group.

Pomegranate Juice Inhibits Sulfoconjugation in Caco-2 Human Colon Carcinoma Cells

Several fruit juices have been reported to cause food-drug interactions, mainly affecting cytochrome P450 activity; however, little is known about the effects of fruit juices on conjugation reactions. Among several fruit juices tested (apple, peach, orange, pineapple, grapefruit, and pomegranate), pomegranate juice potently inhibited the sulfoconjugation of 1-naphthol in Caco-2 cells. This inhibition was both dose- and culture time-dependent, with a 50% inhibitory concentration (IC(50)) value calculated at 2.7% (vol/vol). In contrast, no obvious inhibition of glucuronidation of 1-naphthol in Caco-2 cells was observed by any of the juices examined. Punicalagin, the most abundant antioxidant polyphenol in pomegranate juice, was also found to strongly inhibit sulfoconjugation in Caco-2 cells with an IC(50) of 45 microM, which is consistent with that of pomegranate juice. These data suggest that punicalagin is mainly responsible for the inhibition of sulfoconjugation by pomegranate juice. We additionally demonstrated that pomegranate juice and punicalagin both inhibit phenol sulfotransferase activity in Caco-2 cells in vitro, at concentrations that are almost equivalent to those used in the Caco-2 cells. Pomegranate juice, however, shows no effects on the expression of the sulfotransferase SULT1A family of genes (SULT1A1 and SULT1A3) in Caco-2 cells. These results indicate that the inhibition of sulfotransferase activity by punicalagin in Caco-2 cells is responsible for the reductions seen in 1-naphthyl sulfate accumulation. Our data also suggest that constituents of pomegranate juice, most probably punicalagin, impair the enteric functions of sulfoconjugation and that this might have effects upon the bioavailability of drugs and other compounds present in food and in the environment. These effects might be related to the anticarcinogenic properties of pomegranate juice.

Influence of fruit juices on drug disposition: discrepancies between in vitro and clinical studies

Background: Grapefruit juice is known to alter the pharmacokinetics of over 30 prescription drugs by increasing their bioavailabilities. After the discovery of this interaction almost 20 years ago, there have been many reports investigating the effects of fruit juices on drug disposition. Objective: This article reviews the literature on fruit juice–prescription drug interaction studies to determine which juices are likely to cause clinically significant interactions. Methods: We examined the results from in vitro and clinical studies regarding the interactions between prescription drugs and over ten fruit beverages. Results/conclusions: Grapefruit juice and Seville orange juice caused several clinically significant interactions with cytochrome P4503A (CYP3A). The OATP drug transporter was inhibited by grapefruit juice, orange juice, and apple juice. Other fruit juices also interacted with drug metabolizing enzymes and transporters in vitro, but more studies are needed to determine whether these interactions are clinically significant.

Intervention of antioxidant system function of aged rats by giving fruit juices with different antioxidant capacities

To observe the effects of fruit juices with different antioxidant capacity on antioxidant system function of aged rats. Thirty Wistar rats were randomly divided into three groups: pomegranate juice and apple juice as two experimental groups, while distilled water as normal control group. They were administrated fruit juices or distilled water respectively by gavage daily for 4 weeks. At the end of experiment, the antioxidant system function was assessed. The aged rats in pomegranate juice group showed significantly higher serum antioxidant capacity (0.90 +/- 0.13) mmol/L than that in control group (0.79 +/- 0.10) mmol/L (P < 0.05). The concentrations of serum carbonyl and oxLDL were decreased significantly in pomegranate juice group as compared to the control group (P < 0.05). The percentage of injured blood lymphocyte DNA and the ratio of tail length/total length were declined significantly in pomegranate juice group (P < 0.05 and P < 0.01 respectively). The apple juice showed no effects except decreased ratio of tail length/total length of injured lymphocyte DNA. There were no changes in concentrations of serum vitamin C, vitamin E, urinary 8-OH-dG excretion and the activities of serum SOD, GSH-Px, CAT among three groups. The pomegranate juice should possess higher antioxidant capacity and might improve the antioxidant system function of aged rats, while the apple juice is relatively lower in antioxidant capacity and not very effective. The polyphenols in pomegranate juice might be the important functional components.

PENGARUH PEMBERIAN PERASAN Sechium edule (Jacq.) Swartz TERHADAP KADAR KOLESTEROL TOTAL DAN TRIGLISERIDA SERA MENCIT QUECKERBUS

This research was an effort to reveal the effect of fruit juice of labu siam (Sechium edule (Jacq.) Swartz) on total cholesterol and total glyceride of mice serum and also to reveal the secondary metabolites content of the juice. In this research, four groups of mice each consist of 8 was used. First group ws given normal food, the second group was given hyperlipidemic inducer. The third group was given hyperlipidemic inducer and fruit juice at dosage 0.546 mg/kg b.w. The third group was given hyperlipidemic inducer and fruit juice at dosage 1.092 mg/g b.w. The exogenic and endogenic hyperlipidemic inducers used were cholesterol suspension and propyl thiouracyl 0.01 percent, espectively. Both the inducer and the juice were given every day orally for three weeks. At the last day, the mice were fasted for 12-24 hours and the blood was collected intracardially. Assay of cholesterol and triglyceride in the sera was carried out using the reagent kits. Statistical analysis shows that the administration of the fruit juice of ‘labu siam’ at dosage 0.546 mg/g and 1.092 mg/g b.w. can decrease the triglyceride concentration in the sera. The dose 0.546 mg/g decreases the total cholesterol concentration, but the dose 1.092 mg/g did not show the sera cholesterol decreasing activity. Phytochemical screening for the constituents of the juice indicated that the juice contains saponin glycosides.

The effects of fruit juices on drug disposition: a new model for drug interactions.

Grapefruit juice produces mechanism-based inhibition of intestinal drug metabolism when consumed in normal quantities. This can produce clinically important increases in oral drug bioavailability when coadministered with substrates of cytochrome p450 3A4 (CYP3A4) that undergo high presystemic metabolism. Furanocoumarins such as bergamottin and 6',7'-dihydroxybergamottin have been identified as probable active constituents. Grapefruit juice may also inhibit intestinal P-glycoprotein-mediated efflux transport of drugs such as cyclosporine to increase its oral bioavailability. However, grapefruit juice does not enhance the absorption of digoxin, a prototypical P-glycoprotein substrate, likely because it has high inherent oral bioavailability. Grapefruit and other fruit juices have recently been shown to be potent in vitro inhibitors of a number of organic anion-transporting polypeptides (OATPs). These juices were also found to decrease the absorption of the nonmetabolized OATP substrate, fexofenadine. Taken together, the data support inhibition of intestinal uptake transporters by fruit juices to decrease drug bioavailability. This would represent a new mechanism for food-drug interactions. These findings with grapefruit and other fruit juices continue to enhance our understanding of the complex nature of food-drug interactions, and their possible influence on the clinical effects of medications.

Gastric physiology and function: effects of fruit juices.

The stomach stores food and starts digesting protein and fat. Lipids, sugars, certain amino acids, and nutrients of high osmolality trigger sensory mechanisms from the intestine which inhibit gastric emptying. Food rich in carbohydrates leaves the stomach slower than protein-rich food, and emptying is slowest after a meal containing lipid. For carbohydrate beverages, the gastric emptying rate is primarily determined by the volume, caloric content, and osmolality of fluid ingested. Gastric emptying rates vary among isocaloric beverages of different type (e.g., sucrose, fructose, galactose) or forms (e.g., maltodextrins, starches) of carbohydrate. For instance, gastric emptying is faster for a fructose solution compared with isocaloric glucose and galactose solutions. A maltodextrin or a sucrose solution empties faster than a glucose solution. This is possibly due to the greater inhibitory feedback associated with the introduction of glucose in the duodenum. In addition, fruit juices contain soluble fibers which further modulate the gastric emptying. Noninvasive methods to study gastric emptying have recently been developed. The pattern of the myoelectric activity of the gastric contraction and the effect of meals on this pattern can now be recorded by cutaneous electrodes. In healthy children ingesting different juices, the myoelectric pattern of the stomach (indicator of the gastric emptying) correlates with the carbohydrate absorption (measured by breath hydrogen excretion). Fast gastric emptying was associated with greater production of breath hydrogen. The malabsorption of juice carbohydrates may in part be related to their effect on gastric motility.
