Drink your coffee black, without sugar or dairy products, to maximize its protective health benefits and avoid canceling out its beneficial effects on mortality.

Regular coffee consumption is indeed correlated, in several large-scale observational studies, with a reduction in the risk of all-cause mortality. The claim that milk proteins (caseins) can bind to polyphenols (notably chlorogenic acid) is supported by in vitro and small pharmacokinetic studies, suggesting a reduction in their immediate bioavailability. However, stating that this completely "cancels" health benefits is an extrapolation; the actual impact on long-term health outcomes remains debated and difficult to isolate. Regarding the addition of saturated fats, the warning about cardiovascular markers (ApoB/LDL-C) is consistent with standard nutritional recommendations for heart health. In summary, while black coffee optimizes antioxidant intake without superfluous calories, the data do not allow us to state with certainty that adding a splash of milk eliminates all the protective advantages of coffee. This is an important nuance between the chemical absorption of compounds and the overall clinical impact on longevity.
