Drinking coffee can change your brain structure
Regular caffeine intake can reduce the volume of gray matter in the brain, suggesting that coffee intake can impair information processing, according to a new study.
Swiss researchers gave volunteers three 150 mg of caffeine a day for 10 days. That's the equivalent of about 4-5 small cups of filter coffee or six or seven espresso per day. As a result, they found a reduction in gray matter, which is mostly found in the outermost layer of the brain, or cortex, and serves to process information.
