Recent research has highlighted the potential health benefits of moderate coffee consumption, suggesting that it may lower the risk of dementia and cardiovascular diseases. A study conducted in 2025 indicated that individuals who drink caffeinated coffee, particularly in the morning, could experience reduced mortality risk from cardiovascular issues compared to non-coffee drinkers. The findings suggest that those who consume coffee primarily in the morning show a more significant benefit compared to those who drink it throughout the day.
Another study published in February 2025 in JAMA found that moderate intake of caffeinated coffee (2 to 3 cups) or tea (1 to 2 cups) is associated with a lower risk of dementia and cognitive decline. This research, which involved over 131,000 participants, revealed that those with higher coffee consumption had an 18% reduced risk of developing dementia, alongside improved cognitive performance on various tests.
The studies highlight that while coffee can offer health benefits, moderation is essential. The addition of cream and sugar may negate some of these advantages. Experts recommend that for healthy adults, a daily intake of approximately 2 to 4 cups of mostly unsweetened coffee aligns with heart and brain health guidelines.
Despite these promising results, researchers caution that these studies are observational, and further investigations are necessary to establish causation. They emphasize that coffee and tea consumption can be part of a broader approach to maintaining cognitive health as one ages, along with other dietary choices rich in polyphenols and nutrients.
