Last Updated: 2026/01/17, It has been confirmed and reliable that caffeine increases blood pressure. Professor Jack James, a psychologist at the University of Reykjavik in Iceland (Reykjavik University), said that although the increase in blood pressure was negligible, the impact on caffeine consumption over a lifetime could be significant from a clinical point of view. I think caffeine intake will also be used in the future.

"it is a confirmed and reliable view that caffeine increases blood pressure." Professor Jack James (Jack James), a psychologist at the University of Reykjavik in Iceland (Reykjavik University), said: "although the increase in blood pressure is negligible, if caffeine is consumed throughout life, the impact may be significant from a clinical point of view. I think caffeine intake will also be considered as one of the risk factors for cardiovascular disease in the future. "

Another paper by Professor James in the Journal of caffeine Research (Journal of Caffeine Research) found that people who regularly consumed caffeine were 14 per cent more likely to die prematurely because of coronary heart disease and 20 per cent more likely to die from stroke.

A few weeks ago, a study by Austrian scientists said that the chemical chlorogenic acid in coffee increases the risk of diabetes and even causes the body to store too much fat. The findings are published in the Journal of Agriculture and Chemistry (Journal of Agriculture and Food Chemistry). After the researchers injected the mice with chlorogenic acid equivalent to five or six cups of coffee a day, the mice became unable to control their blood sugar, developed insulin resistance, and had difficulty losing weight.

Other studies have shown that drinking coffee and tea regularly can reduce the risk of stroke and heart disease, as well as avoid neurodegenerative diseases such as Parkinson's disease. In fact, Harvard researchers conducted a large study that analyzed the results of five studies involving 140000 people, proving that moderate amounts of coffee (four cups a day) can reduce the risk of heart failure. The study was published in the journal Circulation (journal Circulation).

"more and more studies have shown that coffee is beneficial, and this paper is a new evidence." Said Dr. Elizabeth Mostovsky (Dr Elizabeth Mostofsky), who is a postdoctoral student. Drinking coffee can also reduce the risk of type 2 diabetes and some cancers. However, as with any diet, moderate intake is the key. Drinking 10 cups of coffee a day "could be harmful," Dr. Mostovsky said. In addition, her early research showed that a brief blood pressure spike after drinking coffee may increase the risk of stroke, while drinking tea has no such problem.

Professor Rogers pointed out that, in fact, the benefits of coffee and tea come from the antioxidants, which can reduce the body's inflammatory response. Inflammation in the body is considered to be one of the key causes of many diseases, including stroke, cardiovascular disease and cancer, and antioxidants in tea and coffee can reduce the risk of these diseases. As a result, Professor Rogers drinks decaf tea and coffee every day, about five cups of tea and one cup of coffee a day.
