Filter coffee, French press or as an espresso? Many people don’t even get up in the morning without a coffee. Studies still do not fully agree on the health advantages and disadvantages of coffee. But there are interesting findings about which preparation is the healthiest.
With milk, condensed milk, even cream or completely black – with white or brown sugar, with sweetener or pure?
The way you drink coffee can make a difference in terms of its health benefits.
A research team led by nutrition expert Walter C. Willet, doctor and epidemiologist at the Harvard School of Medicine and head of the Nutrition Department at the Harvard School of Public Health, has now found in a study that the method of preparation has just as much influence on it as it is healthy Coffee is.
Healthy or unhealthy: how does coffee affect the body?
For a long time coffee, consumed daily and in large quantities, had a bad reputation.
It promotes cardiovascular diseases, promotes high blood pressure and also has an acidic effect, it was said.
In their study, Willet and his colleagues have now been able to reveal that the right type of coffee is – on the contrary – beneficial to health. Drinking coffee every day can therefore even extend life.
Conclusion of the study: This is how you should prepare coffee
Not the gently prepared espresso, not the coffee with the connoisseur cream from a portafilter machine, but simple filter coffee is the healthiest, according to the researchers.
In addition to the knowledge that coffee can help you lose weight because it curbs the appetite and stimulates the metabolism, the scientists identified other health benefits:
- Filter coffee lowers the cholesterol level,
- enhances pain relief from tablets,
- has an anti-inflammatory effect,
- protects against certain types of cancer (skin, breast, prostate cancer),
- reduces the risk of certain liver diseases (liver fibrosis and cirrhosis) and
- lowers the risk of heart disease.
In an earlier study by the same research team, it was shown in 2006 that moderate coffee consumption also reduced the risk of developing type II diabetes.
Coffee contains important antioxidants and minerals
Coffee contains many phytochemicals such as polyphenols and alkaloids.
These are important antioxidants that have anti-inflammatory effects and protect against free radicals that attack the cell structure and are involved in the development of various diseases (including cancer, cardiovascular diseases).
Coffee also contains a lot of magnesium, potassium and vitamin B3.
In its overall effect, it can therefore have a positive effect on intestinal health and the sugar and fat metabolism.
What makes filter coffee so healthy in particular?
In addition to these good ingredients, roasting the beans can also produce harmful substances. This is why the preparation of coffee is so crucial.
Unfiltered variants, such as coffee from the French press or Turkish coffee, contain so-called diterpenes, which increase the cholesterol level.
The much-praised espresso, which is brewed gently, also contains fewer, but still moderately many harmful substances. Here, too, a certain amount of coffee grounds remains in the cup, which is often drunk along with it.
The bad LDL cholesterol increases the risk of cardiovascular disease in coffees other than filter coffee by a full 11 percent (when consuming six cups a day), according to the study.
Unfiltered coffee is therefore particularly dangerous for people with lipid metabolism disorders.
How many cups of coffee a day are still healthy?
If you drink filter coffee, you don’t have to worry about the amount of coffee. Three to five cups a day are still considered beneficial for health. Of course, the strength and the roast also play a role here.
How bitter you perceive your coffee is, by the way, depends in part on your genes. Some people lack certain receptors that can taste bitter substances, which is why they perceive their coffee as milder than others who have these receptors.
