Research published in May 2013 in the Journal of Psychopharmacology looked at the mood and cognitive benefits of having a chocolate drink every day for a month. Chocolate contains a type of antioxidant called polyphenols, which are thought to boost mood. The 72 female participants were divided into three groups, drinking cocoa with 0 mg, 250 mg, or 500 mg of polyphenols. Those who drank the chocolate with the highest polyphenol count experienced the greatest boost in mood, feeling calmer and more content.
A cup of caffeinated coffee could boost your mood, both short and long term. On a short-term basis, the caffeine provides an immediate pick-me-up — and can provide a social mood boost if you’re at a coffee bar. Plus, a review of data from 12 studies of caffeine and depression suggests that coffee may help protect against depression. According to the results, reported in January 2016 in the journal Molecular Nutrition & Food Research, you’ll get the most protection with about 2 cups (400 milliliters) of coffee per day.
