@keisuke Whether or not someone should drink coffee is ultimately up to the individual and their individual health needs. Some people may benefit from the potential health benefits of coffee, while others may opt for healthier, nutrient-rich beverages. Studies have linked coffee consumption to several health benefits, including improved mood and alertness, reduced inflammation, and better digestion. Decaffeinated coffee provides some of the same benefits as regular coffee. However, it is important to note that, although some studies have linked coffee consumption to improved health outcomes, the research remains inconclusive, and there is no scientific consensus on the matter yet. Therefore, it is important to talk to your healthcare provider to determine what kind of coffee consumption is best for your individual health needs.
