How coffee affects cognition?
Coffee is part of the daily life of many people. In fact, some people can not live without it.
But what it brings to our health?
Of course, coffee is a stimulant. It helps the brain to stay active.
But the new studies found even more interesting findings – it does not only activate the brain but also alleviates psychological problems.
For instance, the latest review of more than two hundred articles found that drinking three to four cups a day reduced the possibility of getting depressed and Parkinson’s disease.
The authors have concluded:
“Coffee consumption was consistently associated with a lower risk of Parkinson’s disease, even after adjustment for smoking, and across all categories of exposure.
Decaffeinated coffee was associated with a lower risk of Parkinson’s disease, which did not reach significance.
Consumption had a consistent association with lover risk of depression and cognitive disorders, especially for Alzheimer’s disease.”
Given all these facts, should you drink coffee?
For those who already drink on a regular basis, you may go on. But the findings do not encourage people to start drinking.
Although drinking coffee has several benefits, too much of it may have a negative impact on the body.
So how many cups should one consume to attain its benefits?
The authors suggest that:
“Coffee consumption seems generally safe within usual levels of intake, with summary estimates indicating largest risk reduction for various health outcomes at three to four cups a day, and more likely to benefit health than harm.”
However, the weakness of the study is that it only established the link, not causation. This means that coffee drinking may or may not the factor behind those health benefits being found.
