Is Filter Coffee Good for You?
Paper-filtered coffee removes cafestol, a compound that raises cholesterol - so filter coffee has a small edge over unfiltered. Here's the full picture.
"Filter coffee" here means coffee brewed through a filter that traps the grounds - a paper pour-over filter, a drip machine, or the fine mesh of a South Indian steel filter. For most healthy adults, moderate filter coffee (2-4 cups) is fine and carries the general benefits linked to coffee. This is general information, not medical advice.
The Filter Advantage: Cafestol
Unfiltered coffee - French press, boiled coffee, Turkish, and to a lesser extent metal-filter espresso - lets through cafestol and kahweol, oily compounds ("diterpenes") that raise LDL cholesterol. A paper filter removes most of them. So paper-filtered coffee has a small edge for people watching cholesterol.
The South Indian steel filter sits in between - its mesh is fine and catches the grounds, but it isn't paper, so it lets through more diterpenes than a pour over and fewer than a press. Adding a paper filter step removes more.
The General Coffee Benefits Still Apply
- Alertness, focus and exercise performance (from caffeine).
- Associations with lower type 2 diabetes and better liver markers.
- Near-zero calories when unsweetened.
The Caveats
- The milk and sugar in a typical South Indian filter coffee are where most of the calories and downside are - not the coffee.
- Sleep - keep the last cup to early afternoon.
- Reflux or a sensitive stomach - filter coffee is gentler than espresso but still acidic for some.
