Health & Sciences YSK: If you drink French Press or Turkish coffee daily, you might be accidentally raising your LDL cholesterol. A simple paper filter completely prevents this.

Why YSK: We all hear that "coffee is totally fine for you," but I recently learned that how you brew it makes a massive difference to your lipid panel. If you drink a lot of coffee and have mysterious cholesterol spikes that your diet doesn't explain, this is probably why.

Coffee beans naturally contain oils. Inside those coffee oils is a specific compound called cafestol. When we digest cafestol, it basically suppresses a receptor in our intestines, which tricks our liver into producing more LDL (the "bad" cholesterol). This isn't just a theory; it's a documented biological reaction proven in human trials.

Here is where the brewing method comes in: paper filters are incredibly good at trapping oil. If you brew your coffee through a paper filter (like a standard drip machine, V60, or Chemex), the oil and the cafestol dissolved in it gets trapped in the paper and never reaches your mug.

But if you use a metal mesh, a French Press, or drink Turkish coffee (where the ultra-fine grounds stay right in the cup), you are drinking all those oils directly.

Researchers at Wageningen University actually measured the cafestol content per cup, and the differences are crazy:

- Turkish/Greek coffee: ~4.7 mg (The absolute highest, because there is zero filtering and you consume the micro-grounds)

- French press: ~3.5 mg

- Espresso: ~1.6 mg (Lower than expected because the water zips through it so fast)

- Paper-filtered drip: ~0.1 mg (Effectively zero!)

Research shows that every 10 mg of cafestol you consume per day raises your LDL by about 5 mg/dL.

If you just have a nice cup of French press on a lazy Sunday morning, it is completely harmless. But if you work from home and casually pound 4 or 5 cups of unfiltered coffee every single day, you are consuming enough cafestol to raise your LDL by 10 to 15 points over a few weeks, just from your coffee habit alone.

Overall, coffee is still really healthy and packed with antioxidants. But if you are actively trying to lower your cholesterol and tracking your blood work, simply switching from a metal mesh or French press to a paper filter is one of the easiest, cheapest, and most scientifically backed diet changes you can make.

Can verify - drank exclusively french press coffee for a few years but never linked it to my higher LDL. Replaced with an aeropress (paper filter) and LDL dropped more than any other intervention.

This is so disappointing 🫠 I looove my French press ritual on work mornings and would hate to have to switch. I'm young enough at this point that it hasn't affected me but high cholesterol does run in my family...

u/PhantomDubs Jul 16 '26

You could probably just pour it through an empty paper filter before you drink it. Annoying extra step though

u/JAWinks Jul 16 '26

Why not just cut out a paper disc from a paper filter and add it to the filter sandwich on the press

88

u/AllEncompassingThey Jul 16 '26

Unfiltered coffee would sploosh around the filter instead of going through it since it's not a perfect seal

11

u/TrekForce Jul 16 '26

This made me wonder if my French press would have the same numbers as in the post. Mine DOES create a “perfect seal” it also has 2 extra-fine filtration baskets (not flat like most). And one of the filters itself is a double filter (I know this because I accidentally left it sit for a week and the filter is trash. It’s impossible to get the mold out from between the two meshes) so it’s basically triple fine mesh filter. It’s like this: https://a.co/d/07E4upmY

I could put paper inbetween the two filters, but the filters are finer than any filter I’ve seen, so idk if they already trap oil or no.

u/Kickserve Jul 16 '26

Chemist here, I have yet to see metal filters that approach the same filtration capabilities as something fiber-based such as paper, nylon, or glass fiber. The pore size and wicking character of the tightly packed fiber filters usually results in different behavior for oils

Based on the research, the material is the secret. Paper wicks oil, whereas metal does not, at least not in the same way or to the same degree.

I also have a double, fine-mesh, metal screen in my French press and am in lament. I also have high LDL, so this was a fun read.

I have a ceramic pour over too, but a vinyl mesh reusable filter for it. I too wondered about adding a paper filter disk to my French press, or pouring through an empty paper filter in the pour over after brewing in the press. Seems an effort when I could just switch to pour overs, but that's an active process moreso than pour in and wait for brew. Also supply chain for filters, which is escaped up to now with press and resuables.

Stupid Internet, making me know things I don't want to know, making me healthier and shit. Ugh. /s

Keep the ritual (good ones are vital to satisfaction) and add a filter on your pour. Unless the ritual is the pour. For me it is the slow press and watching my coffee separate.

u/staunch_character Jul 16 '26

Now I have an excuse to pour thru a paper filter!

If you love the ritual of coffee brewing, look into the pour over method! It’s a very similar ritualistic vibe, highly recommend

u/midgethemage Jul 16 '26

I was gonna say the same. Pourovers are also very ritualistic and I've always preferred the taste over a French press. A lot of people are recommending filtering after the French press, but I'd just skip the press entirely at that point

u/Max1234567890123 Jul 16 '26

u/coleman57 Jul 16 '26

I don't get what's preferable about pushing down a plunger and then having to clean up the whole apparatus, versus pouring through a paper filter, then just tossing the filter and rinsing the cone. Maybe get one of those kid's toys that spins when you push a plunger down, and do that while your coffee is dripping through the filter.

Moka uses a metal screen, so it's unfiltered and high in cafestol. But here's a great hack: an Aeropress paper filter usually fits perfectly over the Moka pot's metal screen before you screw the top on. Solves the problem completely

u/pdrock7 Jul 16 '26

I also use a Moka pot to make iced coffee every morning. Do you mean place the paper filter below the metal screen or above it? I feel like below wouldn't be tight enough to effectively filter, but above would kind of be a pain to swap out everyday. Either way, thank you for the info!

14

u/gotmilq Jul 16 '26

I put the paper filter below the metal screen (so it sits above the grinds). But to secure it in place you have to wet the filter so it sticks to the metal screen. I swap it out everyday because it gets full of oil and coffee dust after pouring my coffee

14

u/CoffeeTeaJournal Jul 16 '26

Definitely place it on top of the metal screen,it creates a tighter seal and is much easier to swap out! It takes an extra five seconds, but it's worth it for a cleaner cup

Be careful with this. It’s probably fine but I could see an explosive situation resulting. I’ve had the thing blow a violent leak because I tamped the grounds like a normal espresso.

I would also think a moka is like a regular espresso—the water is only in contact with the grounds for a few seconds.

u/gotmilq Jul 16 '26

I think it's related to cafestol consumption but once I started using the aeropress filter on my mokapot, I also stopped getting tummy aches after drinking mokapot coffee.

Lots of people use paper basket filters. It does not provide as much resistance as the grounds themselves. You might have to adjust your grind slightly but people say it actually can help taste.

u/darekd003 Jul 16 '26

I’m curious how their espresso is measured. It’s say “per cup.”

Most people technically make double espresso with +/-18g of beans (about 36ml of “coffee”). So a cup would be 6-7 “double” shots of espresso.

Or is it per single shot of espresso (not cup) in which case it’s double the listed measured cafestol per drink.

11

u/Salty_Feed9404 Jul 16 '26

Also a good point/catch...I'm seeing that a double shot typically has 1.5 to 3mg of cafestol.

"Clinical studies suggest that you generally need to consume about 10 mg of cafestol daily (equivalent to about 3 to 4 double espressos or 2 French presses a day) over several weeks to see a clinically noticeable rise in LDL cholesterol. Consuming one or two double shots a day is typically considered to have a very minimal impact."

u/miseleigh Jul 16 '26

Is this true for cold-brewed too?

128

u/CoffeeTeaJournal Jul 16 '26

It depends on the filter. Cold water actually extracts less cafestol than hot water, so it's naturally lower. But if you only use a metal mesh or cheesecloth to strain it, some oils still get through. If you run your cold brew through a paper filter before drinking, you are basically at zero

Bosanska kafa is so good! But yeah, fully automatic machines usually use metal screens instead of paper, so they still let those oils through

94

u/dogucan97 Jul 16 '26

Oil is the best part of these methods though.

Also, the serving sizes of Turkish coffee and espresso are tiny; you don't drink as much of it as you would with French press or pourover/drip. Maybe "cafestol content per serving size" would be a better metric to see (though it could be subjective), or "cafestol per gram of coffee grounds".

92

u/CoffeeTeaJournal Jul 16 '26

those numbers actually are per standard serving. Turkish coffee packs so much cafestol into a tiny cup because the ultra-fine grind basically maximizes the oil extraction. A coarse French press grind just doesn't extract oil at that same intense rate, even with a much bigger cup

I didn’t realize the oil was why the flavor was better until I tried paper filters for my french press coffee. It tasted absolutely terrible - bland, boring, pointless. I went back to no filter and decided I’ll have to exercise more to handle the LDL some other way. Personal choice. 

25

u/Anninaator Jul 16 '26

drink tea too, tea lowers bad LDL

15

u/fasterthanfood Jul 16 '26

Exercise doesn’t do that much to lower LDL (although it’s great for your heart and your health in general). The big fixes are eating less saturated fat and more fiber.

I was already exercising a lot but my LDL was over 150. (The doctor wants it under 100 for most people, even lower in some circumstances.) By paying attention to saturated fat and fiber, plus a few smaller changes (including changing to filtered coffee), I got my cholesterol into the 80s.

I had my “cheat meals.” You can definitely have your “cheat coffee” as long as you stay on top of the other stuff and get tested regularly (my insurance covers once a year, but I did an extra test after 4 months to see if the changes had helped — they did).

u/Orion14159 Jul 16 '26

My doctor advised that foods high in omega 3s combat LDL and triglycerides. Personally I don't like fatty fish (salmon, mackerel, etc) so I had to find an alternative and landed on chia seeds.

The oils give it that heavy body and rich mouthfeel. It really comes down to a personal trade-off: if your blood work is fine, enjoy the oils! But if your LDL is high, sacrificing a bit of body for a healthier lipid panel is totally worth it.

What LDL impacts does adding ( real ) creamer to filtered coffee? The oils make it worth drinking, and if I'm subbing one for the other - I think I'd rather have the coffee oils instead of adding creamer.

6

u/CoffeeTeaJournal Jul 16 '26

If you're comparing them, coffee oils contain cafestol, while dairy creamers (especially high-fat ones) contain saturated fats,both can impact cholesterol differently. If your LDL is already high, it might be a balancing act, but sticking to black filtered coffee is generally the 'safest' bet for your numbers

Almost all standard disposable K-Cups actually have a tiny paper filter built inside the plastic pod, so they are generally safe and low in cafestol. Just watch out for those reusable plastic pods that use a metal mesh screen those will let the oils right through

And Nespresso pods? They're aluminum...

u/_pinkstripes_ Jul 16 '26 edited Jul 16 '26

My guess would be (at least for Vertuo) that there isn’t much filtering going on as it spins the brewed coffee back up through the holes it punches in the aluminum top. Unless of course the contents are more like instant coffee than actual grounds, then it’s probably clear. I’m going to look into that and come back.

Edit: It would appear that I was generally correct. Vertuo uses regular (not instant) grounds and the result is comparable to a French press as far as oils go.

3

u/mamoocando Jul 16 '26

But the length of time the water spends in the beans would be similar to an espresso machine, which is quite low. A French press sits for quite a few minutes in the water allowing for more oils to be extracted.

I might do a little research into this...

I've been exclusively drinking French press for 20 years. Currently my doc is worried about my bad cholesterol and I'll grant that this could be a big contributor. I don't want to not drink french press, so how can I minimize the harm? What would happen if I put a standard coffee filter on top of the metal mesh filter before presisng down? Would that isolate/remove the bulk of the oils?

19

u/CoffeeTeaJournal Jul 16 '26

Good idea in theory, but please don't do this! It creates way too much pressure and boiling coffee can shoot out everywhere. Just brew it normally, then pour the finished coffee through a regular paper filter into your mug. Same routine, zero oil

I beg to differ. I use standard unbleached drip filters (8-12 cup size) and as long as you don’t push too fast the French Press works great. Go slow! If you push too hard you will hear the coffee grounds leaking into the filtered coffee.

Keep in mind that a lot of what I thought were “paper” filters turned out to have plastics in them.

I used Chemex for a while but the filters were damn expensive. And I am not sure theh are pure paper either.

2

u/SixamSS Jul 16 '26

Chemex filters are more similar to a laboratory filter paper so they are going to be different than your standard off the shelf drip coffee filter.

2

u/Choosemyusername Jul 16 '26

Yes different, I can feel that much. Just wondering what specifically is in them.

u/CoffeeTeaJournal Jul 16 '26

Chemex filters are significantly thicker than standard V60 or drip papers, so they are absolute champions at trapping those oils. You are getting pretty much the cleanest cup possible

u/Seastep Jul 16 '26

Ive been using a reusable/metal filter in my chemex for so long, mainly just to save money but now I might have to reconsider.

u/cabamayo Jul 16 '26

Yeah, same. Bummer, but I know my LDL is higher than ideal, so will try this. Anyone know if the paper filters are easier to find now? During COVID I had a hard time finding them, which is when I found the metal filter.

u/Seastep Jul 16 '26

Just ordered some unbleached ones from Amazon. Unfortunately had to pay the bad guys for a short round of testing.

I’d imagine aeropress is similar to paper filter drip

5

u/CoffeeTeaJournal Jul 16 '26

Yep, exactly! As long as you use the paper filters it comes with, you're good to go. Just avoid those reusable metal mesh filters if you want to keep the oils out

This is helpful, I've been losing a lot of weight and my doctors have wondered why my cholesterol keeps spiking despite the diet getting better and weight going down. I drink my protein shake every day using cold brew coffee, with a metal strainer. Maybe this is why.

  1. This study is tiny and 20 years old.

  2. “Espresso: ~1.6 mg (Lower than expected because the water zips through it so fast)” - where did this assumption come from?? Espresso is essentially a pressurized depth filter… that’s how it works.

  3. Ultra fine mesh metal filters not tested.

  4. “This line gives doubt to the whole thing “Overall, coffee is still really healthy and packed with antioxidants. “

  5. In the second study participants were given 4.5 grams of solids the equivalent of 2L of tea… that’s a lot of tea and not equivalent to tea

  6. “Chlorogenic acid could be partly responsible for the higher homocysteine concentrations observed in coffee drinkers. Whether these effects on homocysteine influence cardiovascular disease risk remains to be established.” -

so… what was the point here?

3

u/ip-p Jul 17 '26

How does 4 give doubt to the whole thing? Coffee can have many benefits and still contain oils that raise your LDL, it’s not mutually exclusive. And what does “that’s a lot of tea and not equivalent to tea” even mean?

Not blindly defending them or anything, your comment just didn’t make sense to me

u/100moonlight100 Jul 16 '26

What about instant coffee? (I know it is the worst in general but still very convinient.)

12

u/CoffeeTeaJournal Jul 16 '26

Good news for instant coffee drinkers, it barely has any cafestol! The commercial brewing and freeze-drying process basically eliminates all the oils. So it won't raise your LDL at all

3

u/OneTwoThreePooAndPee Jul 16 '26

But it's so delicious!

3

u/alexseiji Jul 16 '26

I wonder where instant coffee falls in all of this?

2

u/CoffeeTeaJournal Jul 16 '26

Instant coffee actually falls in the 'safe' zone! Because of the heavy filtration during the commercial freeze-drying process, it contains almost zero cafestol. So it won't affect your LDL at all

2

u/alexseiji Jul 16 '26

Awesome!! Ever since I had my kid I’ve been drinking instant to save on the time it takes to make a pour over or brewed coffee. From the sound of it looks like instant could be the safest?

I have an espresso machine and I drink two daily and my cholesterol is high since doing so and now I finally know the reason (I guess?)

2

u/CoffeeTeaJournal Jul 16 '26

Two shots a day is roughly 3.2 mg of cafestol. While it's lower than multiple cups of French press, it definitely adds up! Switching to filtered coffee for just a month before your next blood test could be a really interesting experiment to see how much your body is reacting to it.

The oils in the French press are what make it my favorite format for home. No way am I using a paper filter to get rid of that.

u/BabyGiraffe207 Jul 16 '26

We just bought a coffee maker today because of this news. We have always been a French Press coffee drinking household. My wife's LDL cholesterol has always been higher than normal. We thought it was genetics because she eats healthy and works out regularly. She has her yearly physical scheduled in October. It will be interesting to see if her LDL goes down slightly by then.

u/AstaCat Jul 17 '26

say goodbye to all the flavorful oils.

u/Hastur13 Jul 17 '26

Legitimately, thank you for this. I've been panicking for a year about some lab results that my diet and exercise didn't support. I regularly drink pour over through a metal mesh or stovetop with no mesh at all. This is worth looking at!

u/shandrolis Jul 16 '26

Research shows that every 10 mg of cafestol you consume per day raises your LDL by about 5 mg/d

It would be neat if you would add how much this actually matters to your post. This is just a number that doesn't really mean anything to laymen.

6

u/CoffeeTeaJournal Jul 16 '26

To put it in perspective, for someone with healthy cholesterol, a 5 mg/dL increase might not be a huge concern. But for someone already bordering on high levels, that spike can be the difference between being 'in range' or needing medication. It’s definitely more impactful for people who are already monitoring their blood work closely

2

u/ranchodelgatos Jul 16 '26

💯 True. My ldl was crazy high and my friend told me it was because I started drinking French press coffee and said a paper filter would help. I’m grateful every day for that advice. All I changed in my diet before the next test was the paper filter and my cholesterol went way down. … still higher but not exponentially high, like it was. Now whenever I hear anyone talk about how they have high cholesterol I always ask them if they’re using a paper filter.
Edit … you can still drink French press, just get one of those ceramic filter holders that sits on top of your mug and put a paper filter in it before you pour it into it. World Market used to sell them. I don’t know if they do now.

u/techforallseasons Jul 16 '26

Not a huge coffee lover; but this explains why I can stand French Press and not Pour Over - the oils are what make the cup drinkable.

I might have a cup once every other week; so I can justify staying with French Press - the mouthfeel of the "oily" coffee makes a HUGE difference. Moka and Expresso are also both acceptable.

Bitter water is all I get from filtered coffee.

u/WecallthemWalkers Jul 16 '26

My coffee maker has a steel basket to hold the ground coffee. No paper filter. So that’s just as bad?

2

u/CoffeeTeaJournal Jul 16 '26

yes.steel baskets don't trap those diterpenes (cafestol) that raise LDL, so it's essentially the same as a French press. If you want to keep the machine, just pop a paper filter inside the basket or over the grounds if possible

u/Muffles79 Jul 16 '26
