Drinking coffee with high blood pressure will increase the risk of illness? Professor s conclusion on most research results

 8:44am, 26 June 2025

Reader Arthur used the "Contact Me" on this website the day before yesterday (2024-2-22) to inquire: Hello Professor

, reading your article means that coffee is roughly safe. This report shows that even if people with "light" hypertension "appropriate" drinking coffee will increase cardiovascular disease by 2 times. I wonder if mainstream studies hold the same view? Thank you very much Professor, peace! The link above opens an article published in the Changchun Monthly magazine that day, with the title: Attention! If you have high blood pressure and drink coffee, the risk of 1 disease may increase by twice.

I don't know what "1 disease risk" means.

Its second paragraph is: In the past few years, coffee has almost made coffee and healthy dietary pictures of antioxidants, but in the recent "European Neurological Physics and Pharmacy Medical Association Academic Seminar", a study published in Italy pointed out that it is better for people with high blood pressure to not drink coffee, because even patients with mild hypertension, drinking a lot of coffee will increase the risk of cardiovascular disease by 4 times.

There are many doubts in this paragraph: 1. Why is it said to be "recent" rather than an exact date? 2. Why not name the seminar in English? 3. Why is it said that it is "risk increase 4 times" instead of "risk increase 2 times" as shown in the title?

Plus the weirdness of the article title (1 The risk of disease?), I can't help but wonder if this article in Changchun Monthly was compiled in a blind way. (Note: I have published many articles that point out that "Changchun Monthly" is not reliable)

No matter what, there is really such research, but it is only published in a seminar rather than officially published, so its credibility is mostly 50%.

In fact, past studies have almost agreed that coffee can lower blood pressure (credibility > 90%). For example, published in December last year, the clinical study from Taiwan Moderate or greater daily coffee consumption is associated with lower incidence of metabolic syndrome in Taiwanese military: results from the CHIEF cohort study (The results of the CHIEF team study show that the daily appropriate or more coffee intake of the Taiwan military is related to the lower incidence of charitable syndrome).

Published in July last year, a clinical study from South Korea also said that coffee can lower blood pressure. Please see Coffee intake and hypertension in Korean adults: results from KNHANES 2012-2016 (KNHANES 2012-2016 results).

Published last summer, a review from the United States also said that coffee can lower blood pressure. Please see Impact of Coffee Consumption on Cardiovascular Health.

Published in March last year, a essay on the analysis of the face-to-face ethnic group from Germany also said that coffee can lower blood pressure. See Coffee consumption and associations with blood pressure, LDL-cholesterol and echocardiographic measurements in the general population.

Published in June last year, a comprehensive analysis from Iran, Canada and the UK also said that coffee can lower blood pressure. Please see Coffee Consumption and Risk of Hypertension in Adults: Systematic Review and Meta-Analysis.

Please note that this paper comprehensively analyzes all the papers on "adult coffee intake and hypertension risk", so its conclusion is far higher than the research conclusions published in "Study Conference", "Unreviewed" and "One".

Of course, I know that the conclusions of these articles may not be suitable for the "hypertensive patients" specified in the article "Changchun Monthly" so we are now looking at several studies on "hypertensive patients".

2022: Relationship of Daily Coffee Intake with Vascular Function in Patients with Hypertension. Conclusion: Daily appropriate coffee consumption may have a beneficial effect on endothelial function and vascular smooth muscle function in patients with hypertension.

2023: Coffee and Green Tea Consumption and Cardiovascular Disease Mortality Among People With and Without Hypertension (Coffee and Green Tea Consumption and Cardiovascular Disease Mortality Among People With and Without Hypertension). Conclusion: Excessive drinking of coffee is related to increased risk of cardiovascular disease death in patients with severe hypertension, but it is not related to patients with no hypertension and grade 1 hypertension. In contrast, green tea consumption was not related to increased risk of cardiovascular disease death in all types of patients with hemostatic pressure.

2024: Acute Effects of Coffee Consumption on Blood Pressure and Endothelial Function in Individuals with Hypertension on Antihypertensive Drug Treatment: A Randomized Crossover Trial. Conclusion: Compared with coffee without caffeine and water, caffeine-containing coffee neither promotes acute elevation of blood pressure nor has an improved or harmful effect on endothelial function in patients with hypertension who take coffee.

From these three articles, it can be seen that the article in Changchun Monthly said that "even patients with mild hypertension, as long as they drink a lot of coffee, will increase the risk of cardiovascular disease by 4 times", is difficult to stand firm.
