Glass of Wine a Day May Ward Off Depression
But, moderate drinking might also just be sign of normal social life, researchers add
Wine was the most popular drink and participants who drank two to seven glasses a week were the least likely to suffer from depression, compared to nondrinkers.
These findings remained significant even after the researchers took factors such as smoking, diet and marriage into account.
Eva Redei, a distinguished professor in the department of psychiatry and behavioral sciences at the Feinberg School of Medicine at Northwestern University, in Chicago, also expressed doubts about the direct effect of wine on depression.
"Considering the increase of major depression in the age group examined in this study, the finding of protective effects of moderate alcohol consumption is intriguing," she said.
However, it raises more questions than answers. "Is moderate wine consumption related to increased socialization, decreased cardiovascular events, or as it seems, increased activity? These questions are not answered by this study, but the findings are definitely worth noticing," Redei said.
"Is it possible that 'in vino veritas' [in wine there's truth] reflects a bigger truth?" she asked.
