Espresso, filter coffee or would you prefer instant coffee?

Whether filter coffee, espresso or instant  coffee , there is no evidence that coffee consumption in the usual amounts taken is associated with a health risk, reports nutritionist Anja Baustian from the Society for Nutritional Medicine and Dietetics eV in Aachen. In 2005, an American research group examined the effects of caffeinated and decaffeinated coffee on the heart, blood circulation and  metabolism . Caffeinated coffee had no negative effect whatsoever on the parameters measured: blood pressure, pulse rate and  body mass index, blood sugar level, amount of insulin or various blood lipid values ​​(total cholesterol, HDL, LDL) (1). On the other hand, if you have problems with your cholesterol level, you should rather use filter coffee, as this largely filters out the coffee oils.

Effect of caffeine on the body

After a sumptuous meal, espresso and coffee stimulate gastric acid production and bile secretion, thus getting the stomach and intestines going. Coffee drinkers with a sensitive stomach should opt for an espresso rather than a cup of filter coffee. Because espresso is easier on the stomach than filter coffee.

The reason is the longer and stronger roasting of the  beans . This destroys acids and other irritating substances that often upset the stomach. Caffeine can also increase blood pressure. Therefore, caffeine helps with headaches. However, migraines  and chronic headaches cannot be treated with a cup of coffee.

Different types of production

The most classic way to enjoy a coffee is with the help of the filter method. Espresso is prepared according to the steam pressure principle. It is characterized by its short contact time, around 20 to 30 seconds, between espresso powder and water. Soluble coffee is a product made exclusively from roasted coffee using water. The instant powder is made from the liquid of brewed beans, which are concentrated and dried after the coffee grounds have been removed.

The three differ only slightly in terms of the ingredients. Coffee consists of over 1200 components: insoluble carbohydrates, soluble carbohydrates, coffee oils, Maillard products, alkaloids including caffeine, minerals, acids such as citric, acetic, malic, chlorogenic and quinic acid and 1000 volatile aromatic substances.


Even if coffee is not harmful to health, with a balanced diet, no more than four to five cups should be consumed daily. Except for the preparation, the ingredients and thus the physiological effect are relatively the same. Whether it should be filter coffee, espresso or instant coffee depends solely on taste. References:
