A recent review of over two hundred medical studies showed a correlation between coffee intake and how likely a person is to develop Parkinson’s, dementia, or depression. It’s not the coffee, but the caffeine; drinking three or four cups over the course of a day was the key level. That amount of caffeine consumption was associated with a lower chance of developing various dementia diseases or depression disorders, even after adjusting the data for other factors such as smoking. Some types of cancers, and even diabetes risk, were also less likely.
- Medical studies have shown coffee drinkers are less likely to be at risk for depression and dementia diseases.
- The correlation between coffee consumption and lower dementia risk held up even after adjusting for other risks, such as smoking.
- Drinking coffee is also linked to reduced risks for certain types of cancer, gallstones, and even type 2 diabetes.
“Decaffeinated coffee was associated with a lower risk of Parkinson’s disease, which did not reach significance.”
