Although drinking coffee has many benefits, it also has disadvantages to health, that is, it leads to an increase in blood lipids. The main reason is that coffee contains coffee oil, in which the diterpenes compounds caffeine (cafestol) and caffeinol (kahweol) can increase the concentration of triglycerides and cholesterol in the blood.

Martijn Katan, a professor at the Institute of Health Sciences at the Free University of Amsterdam in the Netherlands, pointed out that drinking five cups of coffee brewed in a French filter pot a day, which contains about 10 to 13 milligrams of coffee oil, raises cholesterol in the body's blood by 60.8 per cent in four weeks.

Another study also pointed out that drinking 60 milligrams of coffee oil a day is enough to increase low-density lipoprotein cholesterol and triglycerides in the body. Han Huizong, a coffee expert in Taiwan, points out that coffee beans contain 1% coffee oil. as long as you drink more than 6 grams of coffee, you will consume more than 60 milligrams of coffee oil, which is bad for your health.

What should I do?

Just add a piece of filter paper.

The Harvard Health Newsletter (Harvard Health Letter) issued by Harvard University in early 2012 suggested that filter paper can filter out most caffeine and caffeine, effectively reducing the disadvantages of rising blood lipids.

Han Huaizong points out that coffee brewed without filter paper, such as Nordic brewed coffee, French filter pot, and Turkish kettle, contains about 612 milligrams of caffeine and caffeinol per cup, while coffee brewed with filter paper contains only about 0.2 to 0.6 milligrams. The difference between the two is 20 to 30 times. Although the brewing methods such as mocha pot and siphon pot are filtered, they are made of metal or coarse cotton cloth, and the effect of adsorbing coffee oil is still limited.

Therefore, he suggests that in order to protect cardiovascular health and reduce the intake of caffeine and caffeine, filter paper should be used to brew coffee. If coffee is usually cooked with espresso machines, mocha pots, siphon pots, and French filter pots, it is best to go through one more procedure and filter them with filter paper before drinking.
