The caffeine content in different types of coffee can affect its health benefits. While moderate consumption of caffeine has been linked to various health benefits such as reduced risk of Parkinson's disease and depression, excessive intake may negate these positive effects. Additionally, different types of coffee contain varying levels of caffeine; for example, espresso typically contains higher concentrations compared to drip-brewed coffee. Therefore, individuals should be mindful of their overall caffeine intake from all sources to maximize the potential health benefits while minimizing any negative effects associated with excessive consumption.
