There’s something almost meditative about making French press coffee. You add your grounds, pour in hot water, wait a few minutes, and then push that plunger down with a slow, satisfying press. The result is a cup that’s richer, fuller, and bolder than what a drip machine puts out. Millions of people swear by it. But is this beloved brewing method doing your body a favor, or is it quietly working against you? The answer, as with most things in health, is: it depends.

What Makes French Press Different

When you brew coffee in a standard drip machine or pour-over setup, the water passes through a paper filter before it reaches your cup. That paper does more than you might think. It catches tiny coffee grounds, but it also traps the natural oils that coffee beans release during brewing.

French press skips the paper entirely. Its metal mesh plunger holds back the coarse grounds, but it lets those oily compounds pass right through into your cup. That’s part of what gives French press coffee its signature richness. And those oils are where the health story gets interesting.

Meet Cafestol and Kahweol

The two compounds at the center of this conversation are called cafestol and kahweol. They belong to a class of substances called diterpenes, which are natural compounds found in coffee beans. In a French press brew, these oils flow freely into your cup. In a paper-filtered cup, they mostly stay behind.

According to cardiologist Robert Fishberg, the concentration of cafestol in French press coffee is roughly 300 times greater than in paper-filtered drip coffee. That’s not a small difference.

Research published in the American Journal of Epidemiology found that drinking five cups of French press coffee daily could raise LDL cholesterol, the “bad” cholesterol, by 6 to 8 percent over just four weeks. LDL is the substance that builds up in your arteries over time, narrowing them and raising the risk of heart attack and stroke. A 2022 review published in the cardiology journal Open Heart linked elevated blood cholesterol to drinking six or more cups of unfiltered coffee per day. And a landmark 2020 study in the European Journal of Preventive Cardiology, which tracked more than 500,000 Norwegians over 20 years, found that people who drank filtered coffee were 15 percent less likely to die prematurely, with those drinking one to four filtered cups daily showing the lowest mortality rates.

Those are numbers worth knowing.

But Here’s the Other Side

Before you empty your French press into the trash, let’s look at the full picture.

Cafestol and kahweol are the same compounds that researchers have found may offer some surprising benefits. A review published in the International Journal of Molecular Sciences found that both compounds have documented anti-inflammatory, anti-cancer, anti-diabetic, and liver-protective properties. Kahweol also appears to support mitochondrial protection, meaning it may help the tiny energy-generating structures inside your cells work more effectively.

Coffee beans contain over 1,000 bioactive compounds, and researchers are still working to understand how they all interact inside the human body. A 2024 review in the journal Nutrients concluded that moderate coffee consumption isn’t detrimental to cardiovascular health and may actually be associated with reduced cardiovascular risk in several observational studies.

Coffee also contains compounds formed during roasting called phenylindanes, which researchers believe may help block the buildup of proteins in the brain linked to Alzheimer’s disease. And a 2023 study found that drinking two to three cups of unsweetened coffee daily may lower the risk of depression and anxiety.

So the picture isn’t simple. French press coffee carries both risks and potential benefits, and they often come from the same source: those oily diterpene compounds that the metal mesh filter allows to pass through.

How Much Is Too Much?

Context matters a lot here. Registered dietitian Stefani Sassos, of the Good Housekeeping Institute, points out that research suggests it takes about five cups per day of French press to show a measurable increase in serum cholesterol and triglycerides. If you’re having one or two cups in the morning, the risk is considerably lower than if you’re drinking a full French press pot all day long.

The FDA considers up to 400 milligrams of caffeine daily, roughly four to five cups of coffee, to be generally safe for most healthy adults.

A 2025 laboratory study measuring cafestol and kahweol levels across different brewing methods found that French press coffee contained intermediate levels of both compounds, significantly less than boiled coffee but more than paper-filtered options.

Who Should Pay Attention

Not everyone processes these compounds the same way. People who already have high cholesterol, a family history of heart disease, or other cardiovascular risk factors should be especially thoughtful about how much unfiltered coffee they’re drinking. If that’s you, it doesn’t mean you have to give up French press entirely. But alternating with filtered coffee on most days is a sensible and practical approach.

If you’re on cholesterol-lowering medication or other heart-related prescriptions, it’s worth having a five-minute conversation with your doctor about your coffee habits. That’s a small investment that could matter.

What You Can Do

If you love your French press but want to lower your exposure to cafestol and kahweol, there are some practical adjustments that can help. Running your pressed coffee through a paper cone filter on the way to your mug dramatically reduces the oil content. Keeping your steep time to no more than four minutes also limits how much oil the grounds release into the water. Using a coarser grind, drinking one to two cups rather than four or five, and skipping the sediment that settles at the bottom of your cup are all simple steps that can make a meaningful difference.

The Bottom Line

French press coffee is genuinely delicious, and for most healthy adults drinking one to two cups a day, it’s likely not a meaningful health risk. But if your cholesterol is already heading in the wrong direction, or if heart disease runs in your family, your morning ritual might deserve a second look.

Science doesn’t ask you to stop enjoying coffee. It just asks you to pay attention to how much you’re drinking, how you’re brewing it, and what’s already happening in your body. A conversation with your doctor about your lipid levels and your coffee habits takes maybe five minutes and could be genuinely useful.

Your coffee can still be rich and full-bodied. It just might be smarter to keep it to one or two cups, made with a little more awareness.
