For years, coffee has been a subject of debate, with studies highlighting both its benefits and potential drawbacks. As one of the most widely consumed beverages globally, with approximately 2 billion cups drunk every day, coffee has been linked to numerous health effects. Some studies suggest that coffee may lower the risk of chronic diseases like type 2 diabetes, liver disease, and obesity due to its rich content of nutrients and antioxidants. However, there are concerns about its potential to cause issues like increased anxiety, migraines, sleep disturbances, and gastrointestinal problems.
A recent review conducted by researchers at the University of Coimbra in Portugal, published in Ageing Research Reviews, sheds light on the potential positive effects of regular coffee drinking. This review examined over 50 studies and concluded that coffee could add an average of 1.8 years of healthy living to a person’s life.
The study was funded by the Institute for Scientific Information on Coffee (ISIC), an organization supported by coffee industry giants such as illycaffè, Nestlé, and Lavazza. Rodrigo Cunha, PhD, the lead author of the study, explained that coffee’s molecular components, including chlorogenic acids, provide antioxidants that help protect our cells from damage and improve cell recovery. Additionally, caffeine plays a role in preserving cell function by reducing stress signals in the body.
However, the review also acknowledged that more research is needed to determine who will benefit the most from coffee and how different types of coffee or consumption patterns affect health outcomes.
Scott Kaiser, MD, a geriatrician who was not involved in the study, expressed his support for the review, emphasizing its relevance in the context of the aging global population. Kaiser noted that coffee could be an accessible lifestyle factor to support healthy aging.
Monique Richard, MS, RDN, a registered dietitian, shared practical tips for coffee drinkers. She advised moderation, suggesting that 3-5 cups of coffee per day (about 400 mg of caffeine) may be ideal for health benefits. Richard also highlighted the importance of avoiding excessive sugar and additives, which can negate some of the positive effects of coffee. She further suggested that people who experience adverse side effects like jitteriness or sleep disturbances should consider switching to decaffeinated coffee or adjusting their intake.
In conclusion, while coffee may not be a magical health elixir, it offers a range of potential benefits, particularly when consumed in moderation as part of a balanced lifestyle.
