Coffee is one of the most consumed beverages in the world, loved especially for its taste, warming effect, and invigorating caffeine content. But what does coffee actually do in the body, and how does it affect blood values and health in the long term?
Coffee is packed with bioactive compounds that affect the body in various ways:
Caffeine has a quick blood pressure-raising effect, especially in individuals who do not drink coffee regularly. However, this effect is usually short-lived, rarely lasting more than two hours, and is milder in habitual coffee drinkers due to tolerance. For most healthy individuals, coffee is not harmful to blood pressure in the long term, but those with high blood pressure should consume it in moderation.
Coffee can influence cholesterol levels, and the key factor is how the coffee is prepared. Boiled coffee and French press coffee (including cold brew) contain more cafestol and kahweol, which can raise LDL cholesterol. Filtered coffee, on the other hand, traps these substances and does not negatively affect cholesterol levels.
Tip: If you have high blood lipid levels, it’s best to drink filtered coffee.
Research shows that coffee can influence insulin sensitivity:
The antioxidants in coffee are believed to have a protective effect, which, in the long term, compensates for the impact of caffeine.
Coffee has been shown to have protective effects on the liver:
Both caffeinated and decaffeinated coffee appear to have these positive effects.
Regular coffee consumption in moderate amounts (2–4 cups per day) has been linked to:
However, excessive consumption (more than 6–8 cups per day) may cause heart palpitations, restlessness, and sleep disturbances, especially in sensitive individuals.
Coffee contains compounds that inhibit the absorption of plant-based iron. Drinking coffee immediately after a meal may reduce iron absorption by 40–60%. Therefore, if you have low iron levels, it’s advisable to wait at least one hour after eating before drinking coffee.
You can easily measure your body’s iron stores with Puhti’s laboratory tests, which are available without a referral or doctor’s visit. Through Puhti, you can access tests quickly and conveniently, and the results are provided in a clear report. If needed, you can separately order a doctor’s consultation after the tests.
