Researchers have typically focused less on white wine. However, with white wine, they usually separate the grape skins from the grape juice before the fermentation process. Like red wines, manufacturers harvest and crush white wine grapes. White wines are also classified according to the grapes the manufacturers extract them from and the region they harvest the grapes from. The CDC states that excessive alcohol intake caused around 95,000 deaths each year in the United States between 20.Ī person may be more likely to develop migraine if they drink red wine, but there are a range of serious risks associated with consuming alcohol in large amounts.Īccording to the CDC, the short-term health risks associated with drinking any type of alcohol in excess include:īecause of this, people should try to only drink red wine in moderation. Neurological healthĪ 2017 study showed that red wine consumption may lead to a lower level of disability in people with multiple sclerosis. However, the authors also clarified that the complex relationship between gut bacteria and dietary polyphenols means that they cannot be sure of their positive effects on human health. Gut bacteria are essential to a person’s overall health, as they help control the immune system, digest fiber, and contribute to to the health of the central nervous system. One 2018 systemic review that examined seven studies concluded that red wine may help regulate gut bacteria. This means that the body may not absorb it properly to fully obtain its benefits. However, resveratrol has low bioavailability in humans. ability to protect against neurodegenerative conditions.One 2016 study stated that the benefits of resveratrol include its: Because manufacturers leave the skin on the grapes during the fermenting process of red wine, it may be a rich source of resveratrol. Red wine also contains a compound called resveratrol, which is an antioxidant present in grape skin. However, epidemiological studies may produce less reliable data. Heart healthĪ 2017 review by the American Heart Association (AHA) mentioned epidemiological studies that show that a person may have a lower risk of dying from heart disease if they drink red wine. The authors stated that more research is necessary to confirm their findings and the safety of wine intake among people with type 2 diabetes. However, one 2019 study found that red wine did not improve a person’s glucose levels. One 2017 review found that the flavonoids in red wine may protect against type 2 diabetes. Red wine is the most widely studied type of wine in regards to its potential health benefits. They then extract the juice from the fermented grapes, filter it, and bottle it. This is known as the fermentation process. This enables the conversion of sugar into alcohol. They then add yeast to the grape mixture. They crush these grapes with the skin intact, as the skin adds to the flavor and color of the wine. Manufacturers make red wine by harvesting dark grapes. These grapes will have distinct properties, including their flavor and color. Red wines are classified according to the grapes the manufacturers extract them from and the region they harvest the grapes from. harm to a developing fetus, in pregnant people.In many respects, the health risks of wine outweigh any potential benefits it may have.įor example, drinking a lot of wine can lead to negative rather than positive health consequences, including: Therefore, more studies are necessary to confirm the effectiveness of these health benefits for people who drink wine. Moreover, this study only looked at in vitro testing. It is important to note that the amounts of these polyphenols in wine are very low. However, in studies, researchers often consider the benefits of polyphenols in wine independently from the presence of alcohol. The researchers stated that because of these flavonoids, wine may have anticancer and anti-diabetes benefits.įor example, they noted that some polyphenols in wine can prevent or slow the growth of tumor cells, while some can block enzymes and inhibit glucose absorption. One 2019 study into the effects of flavonoids in foods and drinks, including red wine, on neurodegenerative conditions such as Alzheimer’s disease found that they inhibited the formation of proteins that can cause this condition.Ī 2017 review also discussed the health benefits of flavonoids in wine. Flavonoids are natural compounds present in fruit and vegetables and their products, including wine. Most polyphenols in the diet are flavonoids. Polyphenols are micronutrients present in plants.Ī 2019 review that looked into the Mediterranean diet suggested that polyphenols have strong antioxidant activity, which can prevent damage to cells due to oxidative stress and inflammation. Many of these benefits are due to the polyphenol content in wine. Share on Pinterest Felicia Perretti/OffsetĪccording to some research, wine may have potential health benefits.
