Where does coffee come from? Coffee was discovered during the 15th century in Ethiopia and became popular due to its stimulating properties. Like most natural foods, it contains more than 1000 different kinds of substances, of which caffeine is the best known. Coffee is made from seeds of the coffee plant; coffee beans. The coffee beans are dried and roasted. A part is then ground and a part is sold unground.
Caffeine, the most researched substance in coffee, increases alertness. Caffeine leads to a short-term narrowing of blood vessels and leads to an increase in blood pressure. It is thought that coffee is associated with an increased risk of cardiovascular disease. However, the opposite is true. Coffee actually lowers the risk of heart disease.
In addition, caffeine increases the availability of insulin, which could reduce the risk of diabetes. It is also said that caffeine has an inhibitory effect on inflammation. It can be concluded that there is a connection between drinking coffee and reducing the risk of heart attack, stroke, diabetes, infections and even reducing the risk of death.
However, there are a few comments about this. Only a moderate amount of coffee, say 2 to 5 cups per day, has a positive effect on health. With a larger amount of coffee there are more negative than positive consequences.
There is also a difference in the way a cup of coffee is made. Filtered coffee, yes, the way your grandmother always drinks is the healthiest. The coffee-like substances cafestol and kahweol largely remain behind on the filter in filter coffee. With unfiltered coffee, such as cafetière coffee (French press) or coffee made with a percolator, these oils end up in the coffee.
Cafestol and kahweol have been associated with increasing LDL cholesterol, also known as ‘bad’ cholesterol, and therefore with an increase in the risk of cardiovascular disease. The increase in LDL cholesterol has not been demonstrated with filter coffee. Espressos and coffee from cups are in terms of health between filtered and unfiltered coffee. With around 2 to 3 espressos a day, the effect on LDC cholesterol is negligible.
You experience the most positive effects of coffee on your health when you drink 2 to 5 cups of filter coffee per day. With regard to this intake, on average given the relative decrease in the death risk is around 15%. The risk of a heart attack is reduced by 13% and there is a 17% reduction in the risk of a stroke.
So enjoy a cup of coffee, as long as there are no more than 5!
