Scientists have found that drinking two to three cups of coffee a day may significantly reduce your risk of developing dementia, but drinking more won’t help protect your brain any further.
A major study tracked 131,821 American nurses and health professionals for up to 43 years, starting when they were in their early 40s. During this time, 11,033 people – around 8% – developed dementia. But those who drank moderate amounts of caffeinated coffee or tea were notably less likely to be among them.
