People who drink unfiltered coffee have higher LDL cholesterol levels than people who drink filtered coffee.
See the technical phrasing
Consumption of unfiltered coffee leads to higher LDL cholesterol levels than consumption of filtered coffee.
Cafestol, a compound in unfiltered coffee, enters the liver and stops liver cells from making proteins that remove LDL cholesterol from the blood. This causes more LDL cholesterol to stay in the bloodstream.
What the research says
Supports
1 study
Study: Separate effects of the coffee diterpenes cafestol and kahweol on serum lipids and liver aminotransferases.
Unfiltered coffee contains a natural oil called cafestol that raises 'bad' cholesterol, while filtered coffee removes most of it. This study proved that when people consume cafestol, their LDL cholesterol goes up.
Contradicts
1 study
Study: Dose-dependent effect on serum cholesterol and apoprotein B concentrations by consumption of boiled, non-filtered coffee.
This study found that unfiltered coffee raises LDL cholesterol about the same amount as filtered coffee — so it doesn't raise it more, which means the claim is wrong.
