Three cups of tea or coffee a day could lower dementia risk, study suggests

New scientific research has provided a refreshing incentive for the UK's beverage lovers, suggesting that regular consumption of tea or coffee may offer significant protection against cognitive decline. The study indicates that individuals who enjoy approximately three cups of these caffeinated drinks daily could see a reduced risk of developing dementia in later life.

For the Turkish community across London, where the culture of tea (çay) and coffee is a cornerstone of social life in boroughs like Enfield, Hackney, and Haringey, these findings offer a welcome health-based justification for a beloved daily ritual.

The science behind the brew

The research, which monitored thousands of participants over several years, looked at the long-term impact of caffeine and antioxidants on brain health.

• Cognitive Protection: The study found that caffeine may help block specific receptors in the brain associated with age-related cognitive impairment.

• Antioxidant Benefits: Both tea and coffee are rich in polyphenols, which help reduce inflammation and oxidative stress—factors often linked to the onset of dementia.

• Optimal Dosage: The "sweet spot" identified by researchers was three cups per day; those within this range showed a noticeably lower rate of memory-related issues compared to those who avoided these drinks or consumed them in excess.

A cultural staple with health benefits

In the vibrant social hubs of Islington, Barnet, and Waltham Forest, the Turkish café culture plays a vital role in bringing people together. This new data suggests that the hours spent over a glass of tea or a cup of Turkish coffee might be doing more than just fostering community—they may be actively preserving the cognitive health of the diaspora.

"Tea and coffee are more than just drinks for our community; they are part of our identity," says a health advisor based in North London. "Knowing that these habits, shared by families from Camden to Newham, could help protect against dementia is very encouraging, especially as we look for natural ways to support our aging population."

Moderation and lifestyle

While the results are promising, experts in Westminster and Southwark remind the public that beverage consumption should be part of a balanced lifestyle. They note that adding excessive sugar or cream can offset some of the health benefits. Furthermore, maintaining a healthy diet and regular physical activity remains essential for overall brain health for residents throughout Tower Hamlets and the rest of the capital.

As the scientific community continues to explore the link between diet and neurological health, Londoners can feel a bit more confident as they pour their next cup.
