According to a recent study published in the journal Archives of Internal Medicine, coffee can significantly reduce the risk of depression in women, and women who drink four cups of coffee a day can reduce their risk of depression by 20 percent, according to foreign food websites.

The study was conducted by a team led by Dr. Michelle Lucas of the Harvard School of Public Health. They studied 50739 women with an average age of 63 who had a history of drinking coffee dating back to 1980. They were then studied for 10 years from 1996 to 2006. The results showed that women who drank two to three cups of coffee a day were 15 percent less likely to suffer from depression, while women who drank four cups of coffee a day were 20 percent less likely to suffer from depression.

The researchers said that this trial found a negative correlation between coffee consumption and the risk of depression, but it is not known what the effect will be after drinking a lot of coffee, because in this study, very few women drank six or more cups of coffee, accounting for only 0.52%. And this study only shows that coffee has a protective effect, but it is not fully proved that caffeine or coffee reduces the incidence of depression.
