Senior drinkers of wine (Polyphenol) prove higher cognition

Hi everyone, how’s life treating you?   Today, I’m very happy to report wine-lovers that the wine could prevent a decline in cognitive activity as wine Is full of Healthy Polyphenol.

Elderly people who drink wine likely have higher cognitive abilities than those who do not, but the same cannot be said about imbibers of other alcoholic beverages, according to a study.

The study, by a group of researchers led by Mai Kabayama, an assistant professor of community health nursing with Osaka University, was conducted in 2016 and 2017 on 1,217 residents aged around 76 or 86 in Tokyo and Hyogo Prefecture.

The researchers studied the residents’ drinking habits and other traits and evaluated their cognitive functions through memory and attention tests.

The 67 subjects who were wine drinkers had significantly higher cognitive abilities than the remaining 1,150 who did not drink wine, according to the study.

There was, however, no significant difference in the cognitive abilities between drinkers and nondrinkers of six other varieties of alcoholic drinks, including beer and sake.

An earlier scientific report said that drinking wine effectively prevents a decline in cognitive functions, citing the antioxidant effects of certain ingredients, including polyphenols, which are contained in red wine.

Polyphenols play a big part in wine’s claim to health-benefit fame. But we don’t know or actually we can’t explain why wine’s polyphenols are good for us?

Or even what a polyphenol is? For those without degrees in organic chemistry, understanding these compounds can seem daunting.

Let’s break it down.

What is a polyphenol?

Let’s start with an even more common term in the wine-health lexicon: antioxidants, molecules that protect against the harmful effects of oxidation.

Not to be confused with the flaws caused by wine oxidation (which is harmless to our health), oxidation in the human body is the breakdown of oxygen molecules caused by everyday occurrences.

They are such as exercise, metabolizing food and environmental factors such as exposure to air pollutants. Those chemical reactions generate free radicals, which can lead to aging, inflammatory diseases and even cancer.

Wine’s polyphenols come from grapes, mainly from the skins, and because the red-winemaking process involves more extended contact with the grape skins, those wines tend to contain a lot more polyphenols than white wines do.

As a whole, red wine’s polyphenol content has been praised by wellness-conscious drinkers, but there are also specific polyphenols in red wine that have been studied individually for their potential health benefits.

One of the most widely studied polyphenols in wine, resveratrol.

What’s Resveratrol, then?

Resveratrol is naturally produced in plants in response to physical harm, or invasion by pathogens. Also found in high quantities in peanuts, blueberries and cacao.

Resveratrol is extracted from plant sources to create cosmetic products and dietary supplements.

In lab studies, scientists have found that resveratrol offers protective effects against many human health risks.

Two of its chief benefits are its potential to fight different cancers, by inhibiting cancerous cell growth, and its potential to fight cardiovascular disease, by preventing blood-vessel damage, lowering bad cholesterol and raising good cholesterol.

Researchers have also found evidence that resveratrol may help battle neurodegenerative diseases such as Alzheimer’s, by helping to slow the disease’s progression and clearing out harmful plaque buildup in the brain.

It may also stave off type 2 diabetes, by helping regulate insulin.

Resveratrol’s anti-inflammatory properties have also made it a point of study for health issues related to inflammation, such as lung disease and mental health disorders.

However, the amount of resveratrol used to test this polyphenol’s healthy properties isn’t always the amount that is found in an average serving of red wine.

While some studies have shown that quantities of resveratrol found in just one or a few glasses of wine can confer some health benefits, many others have shown that the amounts of resveratrol used to produce other health benefits could require a person to drink as many as hundreds of glasses per day.

Of course, heavy drinking (let alone the impossible task of drinking 100 glasses of wine in one day) is associated with negative health benefits, so consuming lots of wine just to get reap its resveratrol-related benefits is inadvisable.

For now, many scientists remain skeptical that humans could benefit from resveratrol just from moderately drinking wine; others believe that a glass of wine’s resveratrol content still might lend a health boost.

“It is conceivable that lovers of wine have a stronger interest in health and well-being, which may have affected our results,” said Yuya Akaki, one of Kabayama’s co-researchers, who attends the Osaka University graduate school.

“Further studies are necessary because we have yet to establish that wine can effectively prevent dementia.

Excessive drinking has negative effects on cognitive abilities, so moderation is recommended.”

Scientists around the world have been studying the correlation between drinking and cognitive functions, but few have studied possible links with different varieties of alcoholic beverages or elderly subjects, the researchers said.

When all varieties of alcoholic drinks were taken together, a correlation study showed that those who drank alcohol less than one day a week and those who drank between one and six days a week both had significantly higher cognitive abilities than those who did not drink at all.

We encourage everyone to drink an ‘appropriate amount’ of alcohol. It has said.

Finally, we have wine-related two articles, one is “Natto” that goes well with red wine, to be well worth browsing.

Another is “Excessive alcohol use linked to early-onset dementia risk“, thanks
