Coffee's effect on your cholesterol depends on what catches the diterpenes before they reach your cup.Coffee beans contain two natural compounds called diterpenes: cafestol and kahweol. They aren't oils themselves, but they ride along in coffee oil, the lipid fraction of the bean. When hot water passes through ground coffee, those diterpenes get carried into the brew on tiny lipid droplets. Once swallowed and absorbed, cafestol acts on your liver. It activates a receptor called FXR, which suppresses an enzyme called CYP7A1. CYP7A1 is the enzyme your liver uses to convert cholesterol into bile acids. With less of that conversion happening, your liver clears less LDL out of circulation, so blood LDL rises.This is not a fringe finding. It has been replicated across decades of randomized controlled trials. Jee and colleagues (2001, American Journal of Epidemiology) pooled fourteen RCTs and found a clear pattern: unfiltered coffee raised total and LDL cholesterol in a dose-dependent way, while filtered coffee showed essentially no effect. Cai and colleagues (2012, European Journal of Clinical Nutrition) pooled twelve more RCTs in 1,017 subjects and found coffee raised LDL by an average of 5.4 mg/dL, with the largest effects in trials using unfiltered coffee.
>>21997412Part Eleven:The variable that determines whether you get a cup full of diterpenes or a cup that has had them stripped out is the filter material. Paper traps them. Metal mesh, the kind you'll find in a French press, an espresso basket, a percolator, or a moka pot, does not. A 2025 analysis of Swedish workplace coffee (Orrje et al., Nutrition, Metabolism and Cardiovascular Diseases) measured cafestol concentrations across brewing methods. Boiled coffee came in at 939 mg/L. Workplace brewing machines averaged 176 mg/L. French press and percolator landed around 90 mg/L. Some espresso samples reached 2,447 mg/L. Paper-filtered home drip averaged 12 mg/L. The same green coffee bean produces wildly different cardiovascular exposures depending on what comes between the grounds and your cup.The downstream evidence comes from a 20-year prospective study of 508,747 Norwegian adults (Tverdal et al., 2020, European Journal of Preventive Cardiology). Adults who drank filtered coffee had about 15% lower all-cause mortality compared with non-drinkers. Unfiltered coffee drinkers showed a weaker, less consistent benefit. In adults drinking nine or more unfiltered cups per day, ischemic heart disease mortality was modestly elevated.A few honest caveats. Cafestol's LDL-raising effect is real and reproducible, but the magnitude is moderate, not dramatic. A 5 mg/dL bump in LDL over years matters more for someone with elevated baseline cholesterol or established cardiovascular risk than for someone whose lipids are already excellent. Cloth filters, properly used, also remove a substantial fraction of diterpenes. And coffee carries other compounds: chlorogenic acids, polyphenols, caffeine, and trigonelline have their own metabolic effects, mostly favorable. These compounds are mostly water-soluble. Paper filters trap the lipid-soluble diterpenes while letting the water-soluble actors pass through.
>>21997412don't care.
I drink coffee every day without a filter and last time I went to the doctor they said my cholesterol was too low
>>21997468I guess this one data point proves that OP is lying
>>21997487no need to thank me
>>21997412I'm not going to look too hard because this doesn't concern me (I drink like 1 cup of coffee a week) but>20 years and half a million people is a pretty great study length>'all cause mortality' is a fucking meme
>>21997511>>'all cause mortality' is a fucking memeThe opposite, actually. You either died or didn't die.
>>21997546>drinking unfiltered coffee increases your chance of being hit by a car"all cause mortality" indicates that the author has no fucking idea what's happening, only stats. If you can link something to specific causes of mortality that indicates a consistent detrimental effect, but all cause mortality just intentionally allows all sorts of coincidences and vaguely linked factors to affect your statistics. Any study that looks at all cause mortality is flawed, especially in relation to food and nutrition
>>21997567uh well maybe drinking coffee secretly increases your luck. did you ever think of that?
>>21997412>>21997413What about Instant Coffee?My Mom drinks 2 cups/day.
>>21997412Protip: use 1/2 a paper towel and stick it to big filter
>>21997412I'm willing to make other lifestyle changes to have an occasional espresso. Either way I'll probably live.t. person with a family history of high cholesterol
>>21997737You can just pour your espresso through a paper filter.
>>21997604>drink filtered coffee>cholesterol remains low, overall healthier, coffee gives cognitive boost>can more easily dodge incoming cars
Statins called, they were wondering why you guys were turning your entire life into a miserable punishment diet for a 5% reduction in LDL
>>21997489I want to thank you (for giving me the best day ehs of my life)
>>21997412>coffee nigger say unfiltered coffee bad>un filtered coffee raises testosterone >coffee nigger mad that coffee nigger can't have 14 cups of coffee a day>coffee Chad's have 4 shots of espresso a day. Raise test, give energy, coffee oils reduce anxiety from caffeine drug. >filtered coffee nigger is retarded
>>21997412Did the study account for the fact that drip coffee is much more diluted/less concentrated?
>>21997610Your mother should be raped for disrespecting coffee in such a way.
>>21997412literally nobody is drinking unfiltered coffee
>>21997905Except nobody is drinking an 8 oz cup of pure espresso shots in the morning, let alone three
>>21997412big paper shill thread
>>21997951not all filters are made of paper
>>21997412>Office machine>not drip
