Is Coffee Bad for Cholesterol? It Depends How You Brew It
Unfiltered coffee can raise cholesterol, but filtered coffee may be heart-healthy. Learn how your brewing method affects your lipid levels.

It depends on how you brew it. Filtered coffee is fine for cholesterol, but unfiltered coffee — like French press, espresso, and Turkish coffee — can raise LDL levels significantly.
The Culprit: Cafestol and Kahweol
Coffee beans contain oily compounds called cafestol and kahweol (diterpenes). These are the most potent cholesterol-raising substances in the human diet — more powerful than saturated fat.
Five cups of French press coffee daily can raise LDL cholesterol by 6-8% over four weeks.
Brewing Methods Compared
- Paper-filtered coffee: Removes nearly all cafestol — minimal effect on cholesterol
- French press: High cafestol — can raise LDL significantly
- Espresso: Moderate cafestol — less volume means less impact
- Turkish/Greek coffee: High cafestol — unfiltered grounds
- Instant coffee: Low cafestol — processing removes most
The Heart-Healthy Choice
If you drink multiple cups daily and have elevated cholesterol, switching to paper-filtered coffee is an easy win. A simple paper filter removes 95%+ of the cholesterol-raising compounds while keeping the caffeine and antioxidants.
The Good News
Coffee itself (filtered) is associated with reduced cardiovascular risk. It contains antioxidants and may improve insulin sensitivity. Moderate coffee consumption — 3-4 cups daily — is considered safe for most people.
If you love your French press, you don't have to give it up entirely. Just be aware it may affect your cholesterol, and track your levels to see.
