The Claim
Cafestol is the primary driver of the hyperlipidemic effect of unfiltered coffee, with a substantially greater lipid-raising impact than kahweol, which contributes minimally to increases in cholesterol and triglyceride levels.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Cafestol in unfiltered coffee raises cholesterol and triglycerides more than any other compound in coffee, including kahweol, which has a much smaller effect.
See the scientific wording
Cafestol is the primary driver of the hyperlipidemic effect of unfiltered coffee, as its lipid-raising impact is substantially greater than the additional effect of kahweol, which contributes minimally to cholesterol and triglyceride elevation.
Cafestol blocks the liver from making proteins that remove bad cholesterol from the blood and stops the liver from turning cholesterol into bile acids, so cholesterol builds up in the bloodstream.
What the research says
1 studyThe study gave people pure cafestol and then cafestol plus kahweol, and found that cafestol made cholesterol and triglycerides go up a lot, while kahweol added almost nothing extra. So cafestol is the main culprit in unfiltered coffee that raises bad fats.
