Not that anyone needs a reason to crack open a bottle of wine after a long day of adulting, but knowing its good for your health might make it an even easier choice.

According to a Spanish study that appeared in the American Journal of Clinical Nutrition in May 2012, the polyphenol contents found in wine have positive effects on people’s immune system.

According to Chris Woollams Health Watch the research followed ten healthy middle-aged males who were given merlot, low alcohol red wine or gin for periods of time.

The benefits in the gut bacteria occurred with the Merlot and the low alcohol red wine but not with the gin, leading the researchers to conclude that the benefit came from the polyphenol content of the wine, not from the alcohol.

“There are different kinds of polyphenols, including antioxidants like procyanidins and resveratrol, and each one has different properties and benefits. Resveratrol in particular has been the focus of many scientific studies, and has been found to potentially boost the immune system,” reported the Bright Cellers Blog.

Since everyone is trying to stay healthy with the pandemic still posing a threat on our lives, dry red wines with high levels of tannins and antioxidants should be your go-to.

People who suffer from headaches because of high levels of tannin though are encouraged to go for lower-tannin red wines with high levels of resveratrol like Pinot Noir.
