Black coffee and green tea are the two most studied caffeinated beverages in nutrition science, and both have substantial evidence supporting their health benefits. Black coffee contains more caffeine per serving and has been linked to improved cognitive performance, reduced risk of type 2 diabetes, and liver health benefits. Green tea contains less caffeine but delivers L-theanine — an amino acid that promotes calm alertness — along with a distinct class of antioxidants called catechins associated with cardiovascular and metabolic health. Both are essentially calorie-free when consumed without additions. The choice between them often comes down to personal preference and caffeine sensitivity.
