Red wine or white wine? Doctor reveals the healthier choice, as well as cautionary details

Because some white wines are sweeter, many people assume they're packed with more calories.

"White wine has slightly more sugar, slightly fewer calories [due to lower alcohol content] and fewer antioxidants," she told Fox News Digital. "The differences are negligible."

Stephenson also disputed the myth that red wine is significantly healthier than white.

"Otherwise, there is little difference."

Some research has suggested resveratrol and other polyphenols might influence certain markers like LDL cholesterol or blood vessel function - but these effects are typically observed in lab studies or at high doses not achievable through normal wine consumption, according to a Brown University study.

Though white wine has fewer calories, Stephenson noted that red wine's antioxidant properties may offer some biological effects - while emphasizing risk.

"The less you drink of any alcohol, the better. None is best," she said. 

"However, I know many people are never going to give up drinking wine - so if you want to make the best choice, choose red wine for the antioxidant benefits."

"These also provide the wine experience without the downsides."

"Some people won't be interested in these," added Stephenson. "But they are steadily gaining in popularity."
