The claim that everyone can drink coffee and other caffeinated beverages sounds appealing, but it is oversimplified. Current research shows that the response to caffeine is very individual: after a few weeks of regular consumption, most people develop a tolerance, and the temporary increase in blood pressure after a cup becomes less noticeable. This means that the amount of coffee that is habitual for a particular person most often does not cause chronic hypertension, but it certainly does not guarantee complete safety for everyone.
For people with an innate sensitivity to caffeine or with already diagnosed cardiovascular problems, the situation is different: for them, even one cup can cause palpitations, a feeling of anxiety, or a noticeable increase in blood pressure. Therefore, in such cases, it is better not to rely on general rules, but to consult a cardiologist or family doctor. The doctor will help take into account the medications you are taking and will tell you the permissible limits of consumption.
As for benefits, some meta-analyses have linked moderate coffee consumption to a lower risk of heart disease and even a lower risk of some cancers. Such benefits are often attributed to the complex biological effects of caffeine and antioxidants in coffee and tea. Green tea and certain tea varieties in particular are rich in polyphenols, which have been shown to have anti-inflammatory and vascular effects in experimental models. However, this does not mean that beverages are “cures” for disease; they can be part of a healthy lifestyle, but no beverage is a substitute for a balanced diet, exercise, and medical supervision.
The story is much more straightforward with sugary sodas, packaged juices, and energy drinks with lots of added sugar. Their regular consumption is associated with an increased risk of obesity, type 2 diabetes, metabolic disorders, and cardiovascular disease. If you want to reduce this risk, a smart replacement is water, mineral water, unsweetened tea, or unsweetened coffee. Energy drinks should be treated with caution separately: high doses of caffeine plus other stimulants can create an unexpected strain on the heart, especially in people with rhythm problems.
The practical advice is simple and realistic. Watch yourself: if after coffee you feel palpitations, tremors or severe anxiety - reduce the dose. Measure your blood pressure at different times of the day to understand whether caffeine has a long-term effect in your case. If you are on blood pressure or heart medication, consult your doctor about the permissible amount of caffeine. And remember: water is the simplest and most useful drink, and giving up sweetened carbonated drinks gives an instant plus for metabolism and overall health.
