Consuming two or more cups of coffee per day could double the risk of cardiovascular mortality in people suffering from severe hypertension, whereas a single cup per day does not present this increased risk.

This advice is based on a prospective observational study (JACC) conducted on a large Japanese cohort, published in the Journal of the American Heart Association. The reported association between high coffee consumption (≥2 cups) and increased cardiovascular mortality is specific to individuals with severe hypertension (≥160/100 mmHg) and was not observed in those with normal blood pressure or mild hypertension. It is important to note that this is an observational study, which limits the evidence to a correlation and not a direct causal link. Other research, such as the PAMELA study, has not found similar deleterious effects in hypertensive patients followed over the long term. Furthermore, the limited number of events in the "severe hypertension" subgroup necessitates cautious interpretation. The creator therefore simplifies complex data, but their approach remains cautious by highlighting the role of dosage and individual health profiles.
