Moderate consumption would seem to be a premise to have a healthier life and prevent certain diseases, but little is known about the real effects wine produces. With the purpose of learning about them, doctors Roberto Iermoli and Raúl Pastor, were invited to speak in the seminar of the international contest ‘2011 Vinandino’, held from 14th to 16th September, in Mendoza, Argentina.
The first one to speak in front of a large group of listeners was Iermoli, professor of the 4th Chair of Internal Medicine at ‘Universidad de Buenos Aires’, Argentina. His lecture was focused on the technical aspects of wine effects inside the human body.
Among other topics, the specialist stressed the wine capacity to reduce cardiovascular diseases. “The resveratrol present in red wines increases nitric oxide levels (NO), a component that keeps potassium channels open in the mitochondria of the heart cells, protecting them from oxygen deficiency consequences. This mechanism enables fewer cells die and reduce cell mortality to 50% after a heart attack”, stated the doctor.
Then, he explained: “vascular diseases emerge when bad cholesterol (LDL) is deposited and builds up on the arterial walls, damaging them and ending in an embolism that causes an artery blockage. Afterwards, the tissue supplied by this artery finally dies.”
These details helped to introduce the following explanation. “The alcohol stimulates good cholesterol production (high-density lipoprotein) that removes bad cholesterol (low-density lipoprotein) from arteries and veins where it could form plaques. It also helps lessen the stickiness or coagulation of red blood cells, which can cause an embolism and block the blood flow in an artery (thrombosis) resulting in a myocardial infarction or stroke.”
Besides, he highlighted that alcohol has an anti-inflammatory effect that affects positively blood vessels, holding up the development of atherosclerosis. “Both wine and oil enhance endothelium-dependent relaxation”, he added.
Wine and diabetes
During his lecture, the professor of the ‘Universidad de Buenos Aires’ mentioned the site ‘wineinmoderation.com’. There, people can find the results derived from a research made on a large sample of European population.
One of the conclusions drawn from this study is that moderate alcoholic-beverage consumers have less risk of suffering from diabetes than teetotalers or heavy drinkers. Results coming from a meta-analysis, studying the relation between moderate alcohol consumption and type 2 diabetes, reveal the protective effect against diabetes when wine consumption is moderate.
“It still remains unknown how exactly alcohol decreases risk of suffering from diabetes”, Iermoli explained. “However, researches point out that alcohol could improve body’s insulin resistance, a problem of type 2 or adult-onset diabetes”.
Benefits for brain
Continuing with his lecture, Roberto Iermoli spoke about wine benefits for human brain. This time, he mentioned the web sites ‘lacienciadelvino.com’, in which a work presented by Doctor Guzmán Ortuño Pacheco is available. According to this work, “the daily alcohol consumption should not exceed 40 g, distributed into the two main meals, that is to say 3 glasses, in the case of a red wine containing 12.5% alcohol. As regards women, they should not drink more than two glasses of wine a day.”
In addition, Iermoli made reference to two brain diseases. The first one is called cerebral Ictus, so-called cerebral infarction. About this topic, he stated that resveratrol can make this pathology’s risks be reduced by 30% or 40%. For this, it is necessary to drink two glasses of red wine a day.
The second disease on which wine has benefits is Alzheimer. “The oxidative stress could be the key factor to explain its pathogenesis. Moderate alcohol consumption may lessen the risk of getting Alzheimer.”
The responsible enjoyment of wine
It was then, the turn of doctor, professor and researcher Raúl Pastor. People present at the seminar of 2011 Vinandino had the chance to listen some suggestions about responsible alcohol consumption. “The alcohol abuse is a cellular toxic that damages many organs”, he underlined.
Likewise, he added: “it is important to enjoy the moment and to savor the wine. It has been scientifically proven that enjoying a relaxed time with a glass of wine, helps reduce stress levels and nerves.”
