Effects Of Moderate Wine Consumption Research Articles

Effect of Moderate Wine Consumption on Oxidative Stress Markers in Coronary Heart Disease Patients.

Evidence from research studies reports that wine consumption is associated with lower cardiovascular disease risk, partly through the amelioration of oxidative stress. The aim of the present study was to examine the effect of regular light to moderate wine consumption from coronary heart disease (CHD) patients compared to the effect induced by alcohol intake without the presence of wine microconstituents, on oxidation-induced macromolecular damage as well as on endogenous antioxidant enzyme activity. A randomized, single-blind, controlled, three-arm parallel intervention was carried out, in which 64 CHD patients were allocated to three intervention groups. Group A consumed no alcohol, and Group B (wine) and Group C (ethanol) consumed 27 g of alcohol/day for 8 weeks. Blood and urine samples were collected at baseline and at 4 and 8 weeks. Urine oxidized guanine species levels, protein carbonyls, thiobarbituric acid substances (TBARS) levels, as well as superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, were measured. Oxidized guanine species and protein carbonyl levels were significantly increased in the ethanol group during the intervention and were significantly decreased in the wine group. These results support the idea that wine’s bioactive compounds may exert antioxidant actions that counteract the macromolecular oxidative damage induced by alcohol in CHD patients.

The effect of moderate wine consumption on cytokine secretion by peripheral blood mononuclear cells: A randomized clinical study in coronary heart disease patients

Many studies conclude that wine consumption is related to lower risk for cardiovascular diseases partially through the amelioration of inflammatory biomarkers. The aim of the present study was to examine the effects of wine consumption on the inflammatory response and to compare these effects with the consumption of similar amount of alcohol without the wine micro-constituents in cardiovascular disease patients. Therefore, a randomized, single-blind, controlled, three-arm parallel intervention study was designed. Cardiovascular disease patients were randomly assigned to one of the three groups. In Group A participants consumed no alcohol, in Group B (ethanol group) and Group C (wine group) participants consumed 27 g of alcohol per day. Biological samples were collected at the beginning, on the 4th and 8th week and several biomarkers were measured. Peripheral blood mononuclear cells that were isolated from patients were incubated under basal and inflammatory conditions for 4 and 24 h and the secretion of interleukin 1β (IL-1β) and tumor necrosis factor α (TNFα) was measured. No significant difference was observed among the three groups before the initiation or during the intervention in the most soluble biomarkers. Higher TNFα secretion by peripheral blood mononuclear cells was observed at basal conditions in the ethanol group both at 4 and 24 h of incubation versus baseline secretion. Furthermore, lower secretion of the ΤNFα was observed after 8 weeks of intake in the wine group versus the ethanol group, both at 4 and 24 h of incubation. In conclusion, the light to moderate wine consumption for 8 weeks revealed an attenuation of the ethanol consumption effect on cytokine secretion at basal conditions from the patients’ peripheral blood mononuclear cells.

A multi-omics approach for understanding the effects of moderate wine consumption on human intestinal health.

The human gut is a highly diverse microbial ecosystem. Although showing a well-defined core of dominant taxa, an interindividual variability exists in microbiome arrangement patterns, and the presence and proportion of specific species, determining individual metabolic features-metabotypes-which govern the health effects of dietary interventions (i.e. polyphenol consumption). Starting with a 19-volunteer human intervention study, divided into low, medium, and high wine-polyphenol-metabolizers, we detected interindividual discrepancies on the effect of wine consumption in gut bacterial alpha-diversity, but a significant homogenization of beta-diversity among moderate wine consumers, independently of their metabotype. In addition, the abundance of key health-related taxa such as Akkermansia sp. increased after moderate wine intake in the group of high polyphenol-metabolizers. Regarding the metabolic activity, significant (p < 0.05) positive correlations in the production of SCFAs were observed after wine intake. Finally, we were able to correlate the microbiome and the metabolome of the three metabotypes, and to identify some metabolites-biomarker species, highlighting the genera Phascolarctobacterium, Pelotomaculum and Prevotella, as positively correlated with polyphenol concentration, and Prevotella, Zymophilus and Eubacterium as positively correlated with SCFAs concentration in faeces. Our results contribute to the evidence of the need of including the microbiome variable in personalized nutrition programs, as different metabotyes respond differently to dietary interventions.

Moderate Wine Consumption Reduces Faecal Water Cytotoxicity in Healthy Volunteers.

There are some studies that suggest that moderate consumption of wine, as part of a healthy and balanced diet, has a favourable effect on intestinal health. This study evaluates the effect of moderate wine consumption on faecal water (FW) cytotoxicity as a parameter of gut health. To that end, faecal samples before and after a red wine intervention study (250 mL of wine/day, 4 weeks) in healthy volunteers (n = 8) and in a parallel control group (n = 3) were collected and assayed for in vitro FW cytotoxicity. Two reference compounds, phenol and p-cresol, were used for assessing the cytotoxicity assays using two colon epithelial cell lines (HT-29 and HCT 116) and different assay conditions (FW dilution and incubation time). For the two cell lines and all assay conditions, the means of percentage cell viability were higher (lower cytotoxicity) for samples collected after the red wine intervention than for those collected before, although significant (p < 0.05) differences were only found in certain assay conditions for both cell lines. Significant positive correlations between the percentage cell viability and the contents of some faecal metabolites (short-chain fatty acids (SCFA) and phenolic acids (PA)) were found for the more resistant cell line (HCT 116), suggesting that the reduction in FW cytotoxicity observed after moderate red wine consumption was related to the production of microbial-derived metabolites such as SCFA and PA, whose faecal contents have been shown to increase after wine consumption. FW cytotoxicity can be deemed as a holistic biomarker that involves diet, gut microbiota and host.

European consumers’ perception of moderate wine consumption on health

The present study examines the perceptions that French, Italian and Spanish consumers have about the possible health effects of what they consider to be a moderate wine consumption. Furthermore, it identifies whether the following factors positively or negatively influence consumer opinion – wine appreciation, environmental awareness, environmental labels, local legislation and media coverage. Perceptions were identified through an online survey of 1183 respondents. The respondents perceive wine as a rather healthy product if consumed moderately. Wine appreciation positively influences the perception of a healthy effect of moderate wine consumption. French policies advising constraints on wine consumption indirectly influence consumer opinion about the unhealthy effects caused by wine. French and Spanish consumers with high environmental awareness perceive a wine with an eco-label to be healthier than a conventional one.

Biotechnological Strategies for Controlling Wine Oxidation

Apart from the controversial positive effects of moderate wine consumption on human health, wine antioxidant capacity plays a key role in winemaking technology. From juice extraction to bottle storage, oxygen management is one of the most critical points for making quality wines. In the past, the protection of juice and wine from oxidations was based on the sole use of sulfur dioxide; more recently, the toxicity and the allergenic potential of this additive, together with the increased knowledge on wine oxidation mechanisms, have given rise to new biotechnological approaches and producing trends, leading to a significant reduction of sulfites in winemaking. The aim of this paper is to review the oxidation mechanisms of grape juice and wine and to discuss the opportunities to reduce as much as possible sulfur dioxide addition by a proper management of alcoholic and malolactic fermentation and by the supplementation of some important yeast nutritional factors (e.g., thiamine). The use of natural antioxidants complementing the activity of sulfites (i.e., ascorbic acid, glutathione, yeast lees, and yeast derivatives) is also discussed.

1H‐NMR‐based metabolomic analysis of the effect of moderate wine consumption on subjects with cardiovascular risk factors

Moderate wine consumption is associated with health-promoting activities. An H-NMR-based metabolomic approach was used to identify urinary metabolomic differences of moderate wine intake in the setting of a prospective, randomized, crossover, and controlled trial. Sixty-one male volunteers with high cardiovascular risk factors followed three dietary interventions (28 days): dealcoholized red wine (RWD) (272mL/day, polyphenol control), alcoholized red wine (RWA) (272mL/day) and gin (GIN) (100mL/day, alcohol control). After each period, 24-h urine samples were collected and analyzed by (1) H-NMR. According to the results of a one-way ANOVA, significant markers were grouped in four categories: alcohol-related markers (ethanol); gin-related markers; wine-related markers; and gut microbiota markers (hippurate and 4-hydroxphenylacetic acid). Wine metabolites were classified into two groups; first, metabolites of food metabolome: tartrate (RWA and RWD), ethanol, and mannitol (RWA); and second, biomarkers that relates to endogenous modifications after wine consumption, comprising branched-chain amino acid (BCAA) metabolite (3-methyl-oxovalerate). Additionally, a possible interaction between alcohol and gut-related biomarkers has been identified. To our knowledge, this is the first time that this approach has been applied in a nutritional intervention with red wine. The results show the capacity of this approach to obtain a comprehensive metabolome picture including food metabolome and endogenous biomarkers of moderate wine intake.

Wine Features Related to Safety and Consumer Health: An Integrated Perspective

This review presents a global view of the current situation of the scientific knowledge about aspects of wine with possible repercussions (positive or negative) on consumer health and wine safety. The presence in wine of some potential harmful compounds such as phytosanitary products, trace metal compounds, sulfites, and some toxics of microbial origin, such as ochratoxin A, ethyl carbamate, and biogenic amines, is discussed. The different strategies and alternative methodologies that are being carried out to reduce or to avoid the presence of these substances in wines are also discussed. In recent years much work has focused on establishing the scientific explanations for the positive biological effects of some wine compounds. In this review, we also examine the latest knowledge regarding wine and health, focusing on two types of compounds that have been related to the positive effects of moderate wine consumption, such as phenolic compounds and bioactive peptides.

283 Effect of moderate wine consumption on high density lipoprotein-cholesterol levels in high risk patients: A prospective observational study

Regular light to-moderate wine consumption, defined as 1-3 drinks/day, is associated with a lower risk of cardiovascular disease. Moreover, half of the cardiovascular benefit of wine consumption would be attributable to its High density lipoprotein-cholesterol (HDL-C) rising effect. The aim of this prospective study was to investigate the association between moderate wine consumption and HDL-C levels in patients who survived an acute myocardial infarction (AMI). From the French regional RICO survey, 920 consecutive patients surviving an AMI were included between the 1 st January and the 31 st december 2005. At one year follow-up, patients were asked to report their wine consumption, using a questionnaire and examination of serum lipids was performed. Associations of demographic, clinical, and lifestyle risk-factors with HDL-C levels were assessed with multivariate analysis. Patient consuming 1-3 drink/day of wine had higher HDL-C levels (respectively, 0.47(0.38-0.56) vs 0.43(0.35-0.53) mg/dL, (p=0.026)), and lower CRP concentrations (2(1-5) vs 4(2-7) mg/L (p=0.01)), than non or high-drinkers (0 or >4 drink/day). No difference was reported for triglycerides or LDL-C levels in the two groups. In univariate analyses, CRP levels, diabetes, smoking and body mass index (BMI) were negatively associated with high HDL-C (> 40 mg/dL in men and >50 mg/dL in women). In contrast, female, physical activity and moderate wine intake were positively associated with HDL-C. In multivariate analyses, BMI (OR (95%CI) (0.91(0.87-0.96)), physical activity (OR(95%CI) (1.23(1.07-1.41)) and moderate wine intake (OR(95%CI) (1.84(1.22-3.73)) were associated with high HDL-C. These data suggest that a moderate wine intake is associated with elevated levels HDL-C levels. This association may participate to the beneficial effect of moderate wine intake on cardiovascular disease.

Radioprotective Effect of Moderate Wine Consumption in Patients With Breast Carcinoma

Given the high cost and side effects of radioprotective agents such as amifostine, attention has been focused on potentially equally effective but less expensive and toxic natural substances. We evaluated the potential radioprotective effects of wine in preventing skin toxicity in patients with breast cancer. Before treatment, the medical history and habits of patients were assessed and the information recorded in their clinical folders. Patients were divided into three groups based on the dose/fractionation scheme used: control group, 60.4 Gy (standard technique); Modulated Accelerated Radiotherapy in Adjuvant treatment of breast cancer (MARA)-1 protocol group, 44 Gy (concomitant boost to tumoral bed); and MARA-2 protocol group, 60 Gy (concomitant boost to tumoral bed). The impact of the following variables on acute skin toxicity was evaluated by chart review: radiotherapy protocol, planning target volume (PTV), comorbidity (e.g., hypertension and diabetes), hemoglobin level before therapy, adjuvant hormone therapy, adjuvant chemotherapy, cigarette smoking, and drinking habits. The study population consisted of 348 patients. More severe skin toxicity was significantly associated with the radiotherapy protocol (p < 0.001) and median PTV (p = 0.005). In addition, the incidence of acute toxicity of Grade 2 or greater was higher in patients without alcohol intake (38.4% vs. 22.3%, p = 0.021). The daily amount of alcohol intake also influenced the incidence of skin toxicity, with an incidence of 38.4% in patients with no wine intake, 31.8% in patients drinking half a glass per day, 13.6% in patients drinking one glass per day, and 35.0% in patients drinking two glasses per day. Multivariate analysis showed that wine intake, PTV, and radiotherapy protocol were all significantly correlated with acute toxicity. Our results indicate that wine may have a radioprotective effect; however, prospective studies are needed to confirm this beneficial effect of wine and its components.

What advice should be given to patients with NAFLD about the consumption of alcohol?

Nonalcoholic fatty liver disease (NAFLD) is one of the most common diseases of the Western world, and is associated with an increased risk of cardiovascular disease. The beneficial effects of moderate wine consumption on cardiovascular function are well known. This Viewpoint article discusses potential risks and benefits of alcohol consumption in patients with NAFLD.

Moderate Wine Consumption in the Prevention of Metabolic Syndrome and its Related Medical Complications

The metabolic syndrome (MetS) encompasses a constellation of cardio-metabolic abnormalities associated with a high risk of developing type 2 diabetes and cardiovascular disease (CVD), the top killer in the ageing population. Recent studies have demonstrated multiple beneficial effects of moderate wine consumption in the protection against development of the MetS and its related medical complications. The association of moderate wine consumption with lower incidence of the MetS and atherosclerotic heart disease has been repeatedly documented in numerous epidemiological studies on diverse ethnic groups. In addition to the favorable effects of moderate ethanol intake on lipid profiles, polyphenols enriched in red wine possess multiple benefits on the MetS beyond alcohol through their anti-oxidant, anti-inflammatory, vascular-protective and insulin-sensitizing properties. Notable among these red wine polypheolic compounds is resveratrol, a phytoalexin that has recently attracted great attention due to its role in mimicking calorie restriction. This compound can act as a potent activator of the NAD(+)-dependent deacetylases sirtuins to expand the life span and to prevent the deleterious effects of excess intake on insulin resistance and metabolic derangement. In addition, resveratrol exerts its multiple protective effects against the MetS through stimulating AMP-activated protein kinase and promoting mitochondria biogenesis. In this review, we highlight the recent epidemiological and experimental evidences supporting the protective effects of moderate wine intake against the MetS and its associated cardio-metabolic complications, and discuss the molecular mechanisms underlying the multiple beneficial actions of red wine polyphenols with the focus on resveratrol.

Wine, Diet, and Arterial Hypertension

Hypertension is one of the leading causes of death in developed countries, and the number of prehypertensive patients is increasing. The beneficial effects of moderate wine consumption on cardiovascular diseases have been demonstrated, along with the healthy influence of a Mediterranean dietary pattern. The association of these 2 factors on hypertension and its complications is considered here. As wine polyphenols exert a vasorelaxing action, they might positively influence the hemodynamic situation of these patients. These effects could be enhanced by dietary constituents, such as garlic, onions, and olive oil, which are widely employed in Mediterranean cooking. By evaluating many studies performed in animal models and in humans, the authors conclude that moderate wine consumption, if associated with a healthy dietary pattern, such as the Mediterranean one, could help hypertensive patients to ameliorate their arterial pressure and quality of life by reducing cardiovascular morbidity and mortality rates.

Wine phenolic antioxidants inhibit AP-1 transcriptional activity.

Some of the beneficial effects of moderate wine consumption may be related to the antioxidant properties of polyphenolic compounds containing tannins, flavonoids, and phenolic acids. Cellular actions have recently been reported and may involve the modulation of transcriptional factors such as AP-1 (activator protein-1), which controls the expression of various genes implicated in inflammation processes, cell differentiation, and proliferation. The aim of this study was to evaluate the modulation of AP-1 activity by the phenolic acids (gallic, caffeic, protocatechic, paracoumaric, sinapic, and ferulic acids) that are present in wine and to compare their modulating pathways to those of lipophilic or hydrophilic "chain-breaking" antioxidants (such as DL-alpha-tocopherol or trolox) vitamin C, nitric oxide, and reduced glutathione. AP-1 response was studied on a cell line (MTLN) derived from MCF-7 cells transfected with luciferase gene under TRE sequence control. After stimulation by phorbol 12-myristate 13-acetate (PMA; 100 nM, 6 h, 10(-7) M), luciferase activity was determined by a luminescence method in the presence of luciferine/coenzyme A solution using a luminometer (LKB 1251, Finland). Antioxidants to be tested were incubated with cells in the presence or absence of PMA. Stimulation with PMA resulted in an AP-1-mediated increase in luciferase gene expression corresponding to an 8-fold increase in luciferase activity. After stimulation by PMA, a dose-dependent inhibition of AP-1 was observed with the six phenolic acids in the 20 nM-20 microM concentration range: gallic acid > caffeic > protocatechic, paracoumaric, sinapic acids > ferulic acid. Inhibition was more pronounced with phenolic acids than with DL-alpha-tocopherol (IC(50) = 5 +/- 4.5 microM for gallic acid vs 85 +/- 11 microM for vitamin E). None of the hydrophilic antioxidants inhibited PMA-induced AP-1 activation. None of the antioxidants tested in the absence of PMA stimulation induced any activation or inhibition of AP-1. Our results suggest that phenolic acids may act directly on cell signaling via inhibition of AP-1 transcriptional activity. In addition to preventing LDL oxidation in the arterial wall, our observations indicate that phenolic acids have a cell-mediated capacity to prevent some of the processes involved in atherosclerosis in a plasma concentration range compatible with nutritional intakes.

Induction of net mass lipid transfer reactions in plasma by wine consumption with dinner

Moderate alcohol consumption is associated with a reduced risk of coronary heart disease. Alcohol may exert protection through its effects on the metabolism of plasma lipoproteins. In the present study we investigated the effects of moderate wine consumption with an evening dinner on lipoprotein composition and parameters of reverse cholesterol transport (plasma lipid transfer reactions and cholesterol esterification) in eight healthy middle-aged men. Wine consumption, if compared with mineral water, resulted in increased postprandial plasma levels of triglyceride-(TG)-rich lipoproteins (P < 0.005 or < 0.002 at two different time points) and in increased net mass transfer of cholesterylesters (CE) from high-density lipoprotein (HDL) to apolipoprotein B-containing lipoproteins during in vitro incubation of plasma (P < 0.001). Net mass transfer of TG (in the opposite direction) was also significantly increased by wine (P = 0.014). The concentrations of total plasma cholesterol, HDL-cholesterol and apolipoproteins A-I, A-II and B did not change postprandially and were not affected significantly by wine, but the CE TG-1 in HDL was affected postprandially and decreased by wine consumption. It is concluded that moderate wine consumption with evening dinner induces transfer reactions of CE and TG between HDL and TG-rich lipoproteins. Due to the fact that wine raises plasma TG, it also causes changes in plasma cholesterol metabolism and lipoprotein composition, without major effects on total plasma cholesterol concentration.
