  • For centuries, red wine has been used for health benefits.
  • Muscadine grapes, used in red, white, or rosé wines, are known to have a large amount of a type of antioxidant called polyphenols.
  • Researchers from the University of Florida have found consuming a small amount of dealcoholized wine made from muscadine grapes daily can help improve aging skin.

For many years now, researchers have discussed and debated the potential health benefits of wine, especially red wine.

Wine has been used medicinally for centuries and some believe it is the first recorded “medicine.”

Previous studies show red wine consumption is associated with protection against heart disease, chronic inflammation, and cognitive decline. And other research shows drinking red wine may promote longevity and increase healthy bacteria in the gut microbiome.

Researchers from the University of Florida recently presented research at NUTRITION 2023 — the flagship annual meeting of the American Society for Nutrition — showing dealcoholized wine made from Health">muscadine grapes can help improve aging skin.

For this study, Dr. Lindsey Christman, graduate research assistant in the Food Science and Human Nutrition Department at the University of Florida,and her team recruited 17 women ages 40–67. They were randomly assigned either a dealcoholized wine or a placebo beverage that did not contain polyphenols to drink.

Study participants drank about two glasses of their assigned liquid every day for six weeks. They then took a three-week break and switched to the beverage they had not started the study with for another six weeks.

Researchers measured each participant’s skin conditions and markers of inflammation and oxidative stress at the beginning of the study, as well as at the end of each six-week period.

Upon analysis, scientists found drinking the dealcoholized muscadine wine significantly improved participants’ skin elasticity.

“We were hoping that it would improve elasticity,” Dr. Christman, co-author of this study, told Medical News Today. “Polyphenols in dealcoholized muscadine wine, such as ellagic acid, anthocyanins, quercetin, and myricetin, [may] decrease UVB-induced protease activation. These proteases are responsible for the loss in elasticity — and increase in sagging — often seen with aging.”

Additionally, the wine was associated with a decrease in water loss at the skin surface, indicating the skin had a more effective barrier against damage.

Researchers reported no significant change in the amount of participants’ skin wrinkles during the trial.

And while there were some improvements in skin smoothness and less evidence of inflammation and oxidative stress compared to baseline, there was not a significant difference in these factors when comparing the dealcoholized wine to the placebo drink.
