THE coffee In the work room at work, could contain high levels of substances that increase the levels of “bad” cholesterol in your blood – but there is a simple way to reduce them.
Diterpenes are compounds made by plants that have a variety of effects on the human body. Two of them – cafestol And kahweol – were linked to increased levels Lipoprotein cholesterol with low density (LDL). High levels of these compounds have been found in the coffee, but it seems to depend on How to extract you.
Swedish researchers have measured the levels of diterpenes in coffee made by a range of current coffee machines and brewing techniques. They found that boiling a large coffee jar is the worst offender, but you can easily compensate for these levels by filtering it.
Coffee machines generally found in workplaces around the world have also produced cups of Joe with relatively high levels of diterpene.
“We studied 14 coffee machines and could see that the levels of these substances are much higher in the coffee of these machines than by regular coffee makers” ” Said David iggmanClinical nutritionist at the University of Uppsala.
“From this, we deduce that the filtering process is crucial for the presence of these cholesterol elevation substances in the cafe.”
The team calculated the advantages for a person drinking three cups of coffee per day, five days a week. The exchange of coffee machine for a good paper filtered in paper could reduce enough LDL cholesterol to reduce the relative risk of atherosclerotic cardiovascular disease by 13% over 5 years and 36% over 40 years.
The researchers collected samples of 11 machines that have prepared coffee from mixed dirts with hot water and crossed a metal filter, and from three others that mixed a concentrate of liquid coffee with hot filtration water.
For comparison, the team also prepared a coffee itself using a range of methods, including drip, a percolator, a French press and a boiled coffee. The samples of each method and of each machine were then frozen for storage and transport, before being analyzed for the concentration of diterpene. In addition, the team collected four espresso samples from three cafeterias and a workplace.
The team noted that manual methods of brewing coffee generally led to lower diterpene levels than enter a cup of a machine, Whether it is a brewing machine, a liquid model machine or a traditional espresso manufacturer.
At a glance, the espresso seemed to be the worst way to make coffee, with a median coffee level of about 1,060 mg / L. But there were only four samples analyzed and their levels varied wildly, from 35.6 to 2,446.7 mg / L as such, it is difficult to remove a lot of meaning.
Coffee of models of liquid and brewing machines had a median concentration of cafestol of 174 milligrams per liter and 135 mg / L of Kahweol. The French presses produced coffees with moderate diterpene levels, coming from less than 90 mg / L for coffee and less than 70 mg / L for Kahweol, while the percoleters had similar readings.
The best option seemed to be drip beers filtered in paper, blocking a median of only 11.5 mg / L of Cafestol and 8.2 mg / L for Kahweol.
The exception was boiled coffee, a generally non -filtered method which is common in countries like Sweden. Get your caffeine Fixed in this way has resulted in a massive average concentration of just under 940 mg / L of Cafestol and almost 680 mg / L of Kahweol.
Fortunately, it is easy to reduce these levels. When the researchers filtered their boiled coffee through fabric, the concentrations fell to only 28 mg / l for coffee and 21 mg / l for Kahweol. They have used a sock for any reason, but any fabric or paper filter should do the trick.
The team also acknowledges that the study has major limitations, including small sample sizes and variables that have been not counted, such as filter pores, water pressure and temperature, and how beans were roasted and crushed.
The results join a set of growing and often conflicting research on the effects of coffee health – and it is difficult to know how it all fits. Other studies, for example, have discovered that drinking three cups of coffee or more per day could Reduce your risk develop 40%cardiometabolic diseases.
Regular coffee consumption has also been linked to a drop in the risk of dementia,, ParkinsonAnd skin,, mouthAnd intestine cancer. It could compensate for the negative effects of the health of Prolonged seatand even prolong your life by years. But all of this could depend on How many cups You go down per day, what time You drink them – and now, how you prepare it.
“Most coffee samples contained levels that could affect LDL cholesterol levels of people who drank coffee, as well as their future risk of cardiovascular disease”, ” said iggman. “For people who drink a lot of coffee every day, it is clear that the coffee drip coffee or another well -filtered coffee is preferable.”
