| Latest news | Plus, discover the five healthiest wines you should be drinking. Thankfully, enjoying wine and living a healthy lifestyle are not mutually exclusive. You can have your wine and drink it, too! Basically, that equates to consuming Elevated amounts of alcohol intake increases your risk of high blood pressure, liver and pancreas diseases, cancer, obesity, weight gain, and more. So, always do your best to drink in moderation. Yet certain wines are healthier than others. This is thanks in large part to the varied winemaking processes of each. White wine is typically made by pressing grapes off their skins and fermenting only the juice. While red wine is produced by fermenting crushed grapes with their skins. Then, alcohol and heat during red wine fermentation extract color, flavor, and tannins from the skins, as well as compounds beneficial to our health. These healthy compounds include antioxidants, anthocyanins, flavonoids, polyphenols, and more. More often than not, red wines are also fermented completely dry. Therefore, they typically contain less sugars than white wine. If you must have white wine, do your best to choose one with no residual sugar. Since rosé has spent some time on the skins to obtain that pink color, it will have similar, though significantly less, health benefits as red wine. Drinking red wine in moderation is linked to lowering the risk of heart disease, stroke, and early death. There are numerous naturally occurring compounds in wine that provide these benefits. Red wine contains antioxidants called polyphenols, which boast a number of health benefits. This oxidative stress is linked to aging, cancer, diabetes, and heart disease. Anthocyanins are red, blue, and purple pigment compounds in the flavonoid family. Berries, flowers, grape skins, and other fruits and vegetables contain them. Anthocyanins have many antioxidant and anti-inflammatory properties, including their ability to lower high blood pressure and help manage weight loss. Flavonols are another type of flavonoid, a beneficial compound in fruits and vegetables, found in wine. Again, these help fight inflammation and serve as antioxidants. Flavonols assist in cardiovascular disease prevention and support the formation of healthy blood vessel walls. Fruits, vegetables, and certain medicinal plants contain these natural phytochemical compounds. drinking one glass of wine per day. Pinot Noir has the highest concentration of resveratrol antioxidants. Additionally, while most red wines have low or non-existent residual sugars, Pinot Noir often has a lower initial sugar pre-fermentation. This results in lower alcohol and less calories in the finished wine compared to a higher alcohol wine like Cabernet Sauvignon. As an especially thick-skinned variety, Malbec claims higher antioxidant levels than other red wines especially in terms of resveratrol. This variety has two to four times the amount of anti-inflammatory, health boosting antioxidants than other popular red wines like Cabernet Sauvignon and Merlot. The inclusion in the diet of foods rich in antioxidant compounds could help in counteracting the toxic effects of ROS. Particularly, over the last decade, the moderate consumption of wine, especially red wine, has been associated with the reduction in mortalities mainly from cardiovascular diseases, slowing LDL oxidation, inhibiting platelet aggregation and stimulating nitric oxide production [ 2 ]. Most positive effects of wine are due to the high content of polyphenols mainly flavonoids , which have shown significant antioxidant properties. On these bases, several studies have been focused on the quantification of antioxidant properties of wines, taking into consideration their polyphenol content. The methods used to assess the antioxidant activity differ from each other in terms of chemical bases and reaction conditions. Since a single assay does not accurately reflect all classes of antioxidant molecules, it is recommended the use of two or more assays in order to better describe the antioxidant property of a specific foodstuff in the human body. Considering the importance of polyphenols in wine, the aims of this study were: 1 the evaluation of the total phenolic content TPC in different wine samples, and the set up and application of in vitro methods for a fast screening of antioxidant activity. The methods will include spectrophotometric and chromatographic assays and a novel method, based on the use of an electrochemical biosensor. Biosensors are gaining an increasing role in food analysis; they can be defined as a sub-group of chemical systems, in which the analytical device includes a biological sensor coupled with a chemical or physical transducer. The biosensor used in this study was based on the electrochemical measure of potential to determine concentration of analytes or to characterize the chemical reactivity of a compound. Differential Pulse Voltammetry DPV has been used for quantification, since it is suitable to measure the redox properties of chemical compounds having low molecular weights. Applying a potential, a redox reaction occurs on working electrode surface; electrons involved in the reaction modify the current applied in the cell, and this modification is elaborated by a signal transducer. Results obtained with biosensors were compared with data from spectrophotometric and chromatographic techniques. The antioxidant capacity of samples was also evaluated using the electrochemical biosensor described above. The wine samples included in the study were from different regions from Southern Italy. The abbreviations used in this study are listed in Table 1. Table 1. Wine samples included in the study. Samples of wine Bibeo were kindly offered by Francesca Tassiello Azienda vinicola Pere Rosse, Bitonto, Bari. Other samples were obtained from the market. Before of the analyses, samples were degassed, filtered on a 0. Total polyphenol content TPC was determined according to Singleton and Rossi [ 4 ]. Samples were suitable diluted with water for HPLC VWR, France , and aliquots of μ L were mixed in test tubes with: 1. After 30 minutes, the absorbance was measured at nm in a UV-visible spectrophotometer Varian Cary 50 SCAN, Palo Alto, California, USA. Blank was prepared using μ L of water and treated as described above. The antioxidant activity AOA of wine samples was evaluated spectrophotometrically, as a measure of radical scavenging activity, using 1,1-diphenylpicryl-hydrazyl free radical DPPH [ 5 , 6 ]. The absorbance was measured after 30 minutes at nm. The ABTS assay was performed as described by Re et al. with some modifications [ 7 ]. ABTS radical cation solution was prepared by mixing 2. Aliquots of 1. The absorbance was measured after 6 minutes at nm. High Performance Thin Layer Chromatography HPTLC is a fast and suitable method for the screening of different classes of molecules, allowing the fingerprint characterization of complex products [ 9 ]. Furthermore, HPTLC technique can assess some biological properties, which can be directly associated with any specific compound. Among the possible applications, the semi- quantitative measure of antioxidant activity is here described. Particularly, in this study, HPTLC technique was applied to associate antioxidant activity with wine flavonoids separated by chromatography. For wine samples, volumes of 5 μ L were loaded onto the plate. The chromatographic run was performed by using a mobile phase 10 mL containing acetone:toluene:formic acid 4. At the end of the chromatographic run, the plate was exposed at nm not shown , derivatized with a DPPH Sigma Aldrich, Germany methanolic solution 0. The dried plate was wrapped with aluminium foil for 30 min and exposed at UV nm or at visible light. The images were achieved by using a specific software VisionCats, CAMAG, Muttenz, Switzerland. The band discoloration from violet to yellow was proportional to the antioxidant activity of each phenolic compound. Antioxidant activity of samples was also measured by a new approach based on an electrochemical biosensor, EDEL meter Edel Therapeutics, Lausanne, Switzerland an analytical device, which includes a biological detector coupled with a chemical transducer and specific software Fig. Figure 1. Edel meter with the sensor insert on the right. Gallic acid was used as a reference standard. Working solutions were prepared in phosphate buffer pH 7. Each sample standard solutions or diluted wine samples was transferred in an aluminium-wrapped becker under magnetic stirring. Then, the electrode was inserted in the EDEL meter and immersed in the solutions. After 10 second, the software was launched and measurements, expressed as EDEL units, were recorded each 30s. An example of EDEL scale is reported in Fig. For each sample, the measure was stopped when EDEL values were stable, reaching the plateau status. Figure 2. Preview of EDEL program; EDEL values are shown on the left. The experiments were repeated three times. For each standard concentration, EDEL units were plotted versus time. Then, EDEL values corresponding to the linear part of the curve were used for quantification. At the end of the experiments, a calibration curve was calculated plotting each standard concentration vs the slope values. The calibration line correlated the concentration of standard compounds with slope values. Finally, the same protocol was used for wine samples; the antioxidant activity was measured using gallic acid solutions to prepare the calibration curve. Total polyphenol content TPC and the antioxidant activity AOA quantified using DPPH and ABTS assays are illustrated in Fig. Figure 3. For abbreviations of wine samples see Table 1. As expected for the known contribution of antho- cyanins, the total phenolic content TPC of red wines was higher than that measured in rosé and white wines. The TPC in red wines was eight times and three fold higher than TPC in rosé and white wines, respectively. The red wines SRe and BRe and the rosé wine Bibeo BRo showed the highest phenol content: 5. The lowest polyphenol content was found in white wines Tuglie and Spiavento, and in rosé wine Aro 0. These results were in agreement with data published in the scientific literature [ 9 , 10 ]. In wine samples, antioxidant activity AOA measured using DPPH assay ranged between 0. The AOA quantified using ABTS assay, and expressed as Trolox equivalents, ranged between 5. Wine samples with the highest content of phenol compounds showed also the highest antioxidant activity. Figure 4. Correlation between total polyphenol content and AOA measured by DPPH assay. The high correlation obtained supports the fact that antioxidant activity is mainly due to phenolic compounds. Differences between DPPH and ABTS results depend on the chemical reagent involved. Both assays are based on an electron transfer and involve the reduction of a coloured oxidant. Although different, both assays are strongly correlated with TPC and can be considered useful tools in evaluating the antioxidant capacity of foods [ 11 ]. The innovative approach of HPTLC technique allowed the semi-quantitative measure of antioxidant activity associated with a certain number of active compounds. HPTLC technique allowed a parallel evaluation of antioxidant activity and flavonoid distribution in wine samples. In order to perform a semi-quantitative determination of the antioxidant activity, the plate was exposed at visible light after derivatization with the DPPH solution. To obtain a complete evaluation of flavonoid distribution, the plate was also exposed at nm. Figures 6 and 7 show the flavonoid distribution and the associated antioxidant activity of the wine samples included in this study. Figure 6. HPTLC patterns of wine samples at visible light after derivatization with DPPH solution. Standard flavonoids are run in parallel. HPTLC patterns of wine samples at nm after derivatization with DPPH solution. For abbreviation see Fig. After derivatization with DPPH solution and exposure of the plate at nm Fig. At visible light, hyperoside and epicatechin are clearly detectable in red and rosé wines, both showing also high antioxidant activity.

However, considering the mean AOA values for the different types of wine red, rosé and white a good correlation can be found with DPPH and ABTS analysis Fig.
Figure 9. Mean antioxidant activity in the three classes of wines. It should be noticed that this method is still in development and a higher number of samples is required to validate the results obtained. In the present study, different analytical approaches have been applied to assess the antioxidant activity in wine.
As expected, red wines showed the highest antioxidant activity, followed by rosé and white wines. Although not specific, spectrophotometric methods were useful to obtain preliminary information on the phenolic composition of wines and the associated antioxidant activity.
The HPTLC showed interesting results not only for the screening of active compounds, but also for the evaluation of their specific antioxidant activity; the most usual in vitro assays determine only the total activity. Notably, rosé wines mainly BRo showed an interesting profile for both the total polyphenol content and the antioxidant activity, mainly due to the presence of caftaric acid and epicatechin.
It may also increase insulin sensitivity and resistance to the COVID virus. While a moderate amount of red wine may provide health benefits, consuming too much alcohol can cause devastating health effects. According to the World Health Organization, alcohol is associated with numerous health problems, including cirrhosis, cancers, heart disease, and developmental disorders, and these risks outweigh any potential benefits of red wine 31 , An excessive intake of alcoholic beverages may cause alcohol dependence, liver cirrhosis, or cancer.
It may also increase the risk of depression, disease and premature death. If you like drinking red wine, there is no need to worry unless if you are exceeding the recommended amount. In Europe and America, moderate red wine consumption is considered to be 40 , 41 :.
Keep in mind that this refers to total alcohol intake. Drinking this amount of red wine in addition to other alcoholic beverages could easily put you in the range of excessive consumption. If you have a history of substance abuse, then you should probably avoid wine and any other alcoholic beverage completely.
Also be very careful if you have a family history of alcoholism. Moderate intake of red wine is defined as glasses per day. It is also recommended that you have at least 1—2 days a week without alcohol. Despite red wine being linked with some health benefits, none of them are worthy of encouraging alcohol consumption.
