The next time you fire up your espresso machine or queue up at your local coffee shop, your brain will thank you. Recent research suggests that a daily dose of 200 milligrams of caffeine for adults (about as much as a double shot of espresso) is beneficial to longterm memory. The study tested image recognition over a 24-hour period—adults who were given caffeine pills outperformed those given placebos at recognizing “similar” images, suggesting that the stimulant improves memory consolidation but not necessarily retrieval. This contributes to mounting evidence of the health benefits of moderate caffeine consumption and has us hitting the espresso bar with no regrets.
