Excessive coffee consumption could affect cognitive health in adults over 60 years old.

Coffee, that beverage that accompanies the mornings of millions of people around the world, has been the subject of numerous studies and debates regarding its benefits and possible adverse effects. A recent investigation published by Helsingin Sanomat has shed light on a particular concern: the impact of high coffee consumption on the cognitive health of adults over 60 years old. This study, which analyzed 8,451 individuals in the UK biobank, suggests that drinking more than three cups of coffee a day could be detrimental to this age group. The study found that older adults who consumed more coffee showed a decline in their cognitive abilities compared to those who opted for a more moderate intake. In particular, there was an observed decrease of 8.83% in the flexible intelligence of participants who consumed less coffee, raising serious questions about the balance between enjoying this popular beverage and its implications for mental health as we age. Kelsey R. Sewell, a researcher at the Advent Health Research Institute, warned about the dangers of excessive coffee consumption, citing an old saying: "Excess is bad." This statement resonates particularly in the context of older adults, who may be more susceptible to the adverse effects of caffeine. While coffee can offer benefits, such as increased alertness and improved metabolism of certain nutrients, excess consumption could lead to cognitive decline. It is essential to clarify that the research is observational, meaning that further studies are needed to confirm these findings. Although the correlation between high coffee consumption and cognitive decline is concerning, a definitive cause cannot be established without controlled and more extensive trials. The discussion about the benefits and risks of coffee also includes considerations regarding its preparation and consumption. According to the portal La Tienda del Café, consuming coffee without sugar can offer multiple benefits for the body, including antioxidants and anti-inflammatory properties. However, coffee with sugar can have negative effects, which is also crucial to consider for a healthy lifestyle. Caffeine, the main component of coffee, does not accumulate in the body. After consumption, it is metabolized and excreted through urine within a few hours, meaning its effects can be transient. Specialists suggest that moderate consumption, between 3 and 5 cups a day, is safe as long as the recommended caffeine intake of 400 mg is not exceeded. An interesting aspect of the discussion about coffee is the preference for its temperature. Álvaro Díaz, a nutritionist in Bilbao, points out that hot coffee has a slight advantage in terms of nutritional benefits. Polyphenols and other bioactive compounds are better preserved in hot beverages, which may make it more effective compared to its cold version. However, it is important not to fall into the myth that cold coffee is less effective. Although some compounds may be diluted, the antioxidant effects and other benefits still remain, albeit perhaps to a lesser degree. The temperature of the coffee does not affect its caffeine content, debunking the popular belief that cold coffee might be more energizing. In summary, while coffee is a beverage that many enjoy daily and can offer various benefits, recent research suggests that its consumption should be moderate, especially in people over 60 years old. Cognitive health is a crucial aspect to consider in the aging process, and excessive coffee intake could be a contributing factor to its decline. Science continues to explore the fascinating world of coffee, and consumers should stay informed about emerging evidence to make informed decisions about their daily consumption.
