Can This Drink Reduce the Risk of Depression?
Certain drinks often hit the headlines for being particularly good or bad for you, red wine is one of the more popular ones for being lauded for a variety of health-benefits.
Another common drink that has been historically linked with health gains is tea, from slimming to enhancing sport endurance.
But new research aimed to examine if tea consumption could decrease the risk of depression:
We performed a meta-analysis of findings from observational studies to evaluate the association between tea consumption and depression risk
The researchers systematically searched and collated all of the existing research that compared levels of tea consumption and depression in order to provide a unified answer.
Once the data had been gathered the authors were able to show that tea drinking was beneficial:
The dose–response analysis identified a linear association between tea consumption and the risk of depression, with every 3 cups/day increment in tea consumption associated with a 37% decrease in the risk of depression.
The study proposed several explanations as to why they thought this was found:
Tea polyphenols, mainly catechins, which can enter the brain in significant quantities are posited to play a major protective role in depression development.
These catechins are antioxidants that are naturally occurring in most types of tea, although in differing amounts.
So it seems that while having a cup of tea may not help people with depression it certainly appears to have a protective effect from the risk of depression.
