A new study has found that women aged 65 and older with larger caffeine intakes (more than 261mg per day) are 36% less likely to suffer from dementia over 10 years of follow-up.
For the study, researchers from the University of Wisconsin-Milwaukee looked into the benefits of caffeine consumption on the brain function in postmenopausal women. Specifically, they wanted to find out whether almighty caffeine could delay or help prevent dementia and cognitive decline in 10 years. They were inspired by previous by previous research suggesting caffeine may have some protective affects against cognitive impairment and Alzheimer's Disease, which is the most common cause of dementia.
Caffeine has also be found to protect against Parkinson's disease, reduce kidney stones, and even prevent skin cancer.
So, it may well be that a few coffees a day could keep the doctor away.. or at least help you remember his last name correctly. Play safe though as caffeine overdose could lead to a seizure and be very dangerous.
