Does Coffee Cause High Cholesterol? It Depends How You Brew
Is your daily cup of coffee secretly sabotaging your cholesterol levels? You’ve likely heard conflicting reports, leaving you to wonder if that essential morning brew is helping or harming your heart health. Many people worry that to lower their cholesterol, they might have to give up coffee entirely.
Yes, coffee can raise LDL (“bad”) cholesterol, but this effect almost entirely depends on how you brew it. The key difference is filtration: unfiltered coffee contains natural oily compounds that increase cholesterol, while paper-filtered coffee methods largely remove them, making your brew heart-healthier.
Leveraging an extensive analysis of scientific studies and guidance from leading health institutions, this guide unpacks the simple truth behind the can coffee cause high cholesterol debate. We’ll explore the science, compare the brewing methods, and give you clear, actionable steps to enjoy your coffee without worry.
Key Facts
- The Brewing Method is Critical: Unfiltered coffee, like that from a French press or boiled coffee, contains high levels of compounds that can raise LDL cholesterol. In contrast, paper-filtered drip coffee has a negligible effect, as highlighted by research from sources like the Cleveland Clinic.
- Specific Compounds are the Cause: The culprits are natural coffee oils called diterpenes, specifically cafestol and kahweol. These compounds are known to inhibit the body’s ability to process and eliminate cholesterol, leading to higher levels in the blood.
- Paper Filters are the Solution: A simple paper filter is remarkably effective at trapping the vast majority of these oily diterpenes. Studies show that pouring even boiled coffee through a filter can substantially reduce its cholesterol-raising potential.
- Quantity Plays a Role: The impact is dose-dependent. A 2025 study found that high consumption, defined as more than four cups per day, was directly correlated with increased LDL-cholesterol levels, especially when the coffee was unfiltered.
- Add-ins Can Be Worse: What you put in your coffee often has a greater impact than the coffee itself. As noted by sources like Everyday Health, cream, butter (as in bulletproof coffee), and sugary syrups add saturated fats and calories that directly contribute to high cholesterol.

Does Coffee Raise Cholesterol? The Surprising Truth About Your Brew
Yes, coffee can raise LDL (“bad”) cholesterol, but it primarily depends on how you brew it. Unfiltered coffee contains compounds that increase cholesterol, while filtered coffee largely removes them. So, is your morning cup helping or hurting your heart health? The answer is more complex than you think. According to health authorities like WebMD and the Cleveland Clinic, the link is clear, but it’s conditional.
- The Connection: Certain brewing methods allow natural, oily compounds from coffee beans to get into your mug.
- The Culprits: These compounds, called diterpenes, have been shown to raise levels of LDL cholesterol.
- The Solution: The good news is that a simple paper filter traps most of these compounds, neutralizing the effect.
The Science Explained: Meet Diterpenes, Coffee’s Cholesterol-Raising Compounds
Coffee contains natural oils called diterpenes (specifically cafestol and kahweol) which can raise LDL cholesterol by affecting how the body metabolizes and removes it. To understand why coffee can cause high cholesterol, we need to look at these two specific molecules found naturally in coffee beans. Think of diterpenes as tiny roadblocks that slow down your body’s cholesterol-clearing traffic.
Research indicates the process works like this:
1. Coffee Beans Contain Oils: All coffee beans have natural oils within them. These oils are released during the brewing process, especially when hot water comes into direct, prolonged contact with the grounds.
2. Oils Contain Diterpenes: Within these oils are the two primary diterpenes: cafestol and kahweol. They are responsible for some of coffee’s flavor but also for its effect on cholesterol.
3. Diterpenes Affect Metabolism: Once consumed, studies show these compounds inhibit a key mechanism in the body responsible for metabolizing and excreting cholesterol. This disruption leads to higher levels of LDL (“bad”) cholesterol circulating in the bloodstream.
Why Your Brewing Method is the Most Important Factor
The brewing method is key because paper filters trap the cholesterol-raising diterpenes. Unfiltered methods allow these compounds to pass into your cup, while filtered methods remove them. This single variable—filtration—is more important than the type of bean or roast level when it comes to the coffee and cholesterol connection.
The science is incredibly clear on this point. When you brew coffee using a method that involves pouring hot water through grounds without a paper filter, the oily diterpenes flow directly into your final beverage. However, when you use a paper filter, those same oils get trapped in the paper, along with the cafestol and kahweol.
Pro Tip: The simple act of pouring your coffee through a paper filter is the single most effective way to reduce its impact on your cholesterol.
Coffee to Limit: Unfiltered Methods High in Diterpenes
Unfiltered methods like French press, boiled coffee, Turkish coffee, and espresso contain high levels of cholesterol-raising compounds because they don’t use a paper filter. If you are managing your cholesterol, these are the preparation styles you should moderate or avoid.
- French Press (Plunger Coffee): This popular method, mentioned by numerous sources including Plantstrong, involves steeping grounds in hot water and then pressing them down with a metal mesh filter. This mesh is not fine enough to catch the oily diterpenes.
- Boiled Coffee: Common in Scandinavian countries, this method involves boiling the grounds directly with water, resulting in the highest concentration of diterpenes.
- Turkish Coffee: This preparation involves simmering very fine coffee grounds in water, which are then served along with the liquid, ensuring a high diterpene content.
- Espresso: As a study from UiT The Arctic University of Norway found in 2025, drinking three to five cups of espresso daily was linked to increased cholesterol, particularly in men. Espresso forces hot water through compacted grounds without a paper filter, concentrating the oils.
Quick Fact: Did you know? A study from Uppsala University found many workplace coffee machines use metal filters or liquid concentrates, making your office coffee a potential source of unfiltered brew with higher diterpene levels.
The Cholesterol-Friendly Choice: Filtered Coffee
Paper-filtered coffee, like standard drip or pour-over, is the best choice for cholesterol management as the paper effectively traps the oily diterpenes. If you’re concerned about whether coffee can cause high cholesterol, switching to a filtered method is the most powerful change you can make.
When you use a standard drip coffee machine or a pour-over method, the paper filter acts as a barrier. It allows the water and flavor to pass through but catches the vast majority of the cafestol and kahweol. Health authorities like the Cleveland Clinic and MedStar Health consistently recommend these methods as the safest option for coffee lovers who are also watching their cholesterol.
Comparing Brewing Methods: A Cholesterol-Conscious Guide
Where does your daily brewing method fall on this chart? A direct comparison shows that boiled and French press coffee have the highest cholesterol impact, while standard paper-filtered drip and pour-over methods have the lowest and are considered the best choice.
| Brewing Method | Filter Type | Diterpene Level | Cholesterol Impact |
|---|---|---|---|
| Boiled Coffee | None | Highest | Highest |
| Turkish Coffee | None | Very High | Very High |
| French Press | Metal Mesh | High | High |
| Espresso | None / Metal | Medium-High | Medium-High |
| Pour-Over | Paper | Negligible / Low | Lowest |
| Drip Coffee Machine | Paper | Negligible / Low | Lowest |
Beyond the Brew: Other Factors That Influence Coffee’s Impact
Drinking more than 4 cups of unfiltered coffee daily and adding high-fat ingredients like cream, butter, or certain syrups can significantly increase coffee’s negative impact on cholesterol. Remember, what you put in your coffee can matter just as much as how you make it. A filtered coffee loaded with cream and sugar might defeat the purpose.
- Consumption Quantity: Moderation is key. A 2025 scientific report found a correlation between high coffee consumption (more than four cups per day) and raised LDL-cholesterol levels. The risk is compounded if that coffee is unfiltered.
- High-Fat Add-ins: This is a major factor. As multiple health sources warn, adding sources of saturated fat can dramatically raise your cholesterol.
- Cream and Half-and-Half: These are high in saturated fat.
- Butter or MCT Oil: Bulletproof coffee, which includes these ingredients, is exceptionally high in saturated fat and has been directly linked to sharp increases in LDL cholesterol.
- Sugary Syrups & Whipped Cream: These add empty calories and can contribute to weight gain, which is another risk factor for high cholesterol.
- Genetics: Some people have a genetic predisposition that causes them to metabolize coffee more slowly. For these individuals, the risk of negative cardiovascular effects from high coffee consumption may be elevated.
Don’t Forget the Benefits: Coffee’s Positive Side
Despite its effect on cholesterol, moderate coffee consumption is linked to numerous health benefits, including a lower risk of heart disease, stroke, and type 2 diabetes, due to its high antioxidant content. It’s a balance of risks and rewards. The key is maximizing the benefits while minimizing the risks.
Coffee is more than just caffeine; it contains over 1,000 bioactive substances, including powerful antioxidants and polyphenols. According to a consensus from sources like Healthline, EatingWell, and Verywell Health, regular coffee drinkers may enjoy:
- A lower risk of developing type 2 diabetes.
- Reduced risk of certain liver diseases.
- A lower likelihood of suffering from heart disease and stroke.
- Potential protection against neurodegenerative diseases like Parkinson’s.
Some studies even suggest that these powerful positive effects may help counterbalance the negative cholesterol-raising impact of the diterpenes for many people.
Making the switch to filtered coffee is the single best step you can take. Using high-quality paper coffee filters ensures you remove the vast majority of diterpenes, allowing you to enjoy your coffee with peace of mind.

FAQs About Coffee and Cholesterol
Is black coffee good for cholesterol?
It completely depends on how it’s brewed. Filtered black coffee is an excellent choice, as it’s free of cholesterol-raising diterpenes and has no added sugar or fat. Unfiltered black coffee, like from a French press, is not recommended for those managing cholesterol because it contains high levels of cafestol and kahweol.
What about instant coffee, does it raise cholesterol?
Instant coffee is generally considered to have very low levels of diterpenes. The manufacturing process, which involves brewing the coffee and then dehydrating it, appears to remove most of the oily compounds. Therefore, instant coffee is a much better choice than unfiltered brewing methods like French press or boiled coffee for those concerned about their cholesterol.
Will quitting coffee lower my cholesterol?
It might, but only if you are a heavy consumer of unfiltered coffee. If you drink large amounts of French press or boiled coffee, switching to filtered coffee or quitting could lead to a reduction in your LDL levels. However, for most people drinking moderate amounts of filtered coffee, quitting is unlikely to have a significant impact, as diet and genetics are much larger factors.
Does decaf coffee affect cholesterol?
Yes, decaf coffee can affect cholesterol in the same way as regular coffee. The cholesterol-raising compounds are the diterpenes (cafestol and kahweol), not the caffeine. Therefore, an unfiltered decaf coffee will have the same potential to raise LDL cholesterol as an unfiltered caffeinated coffee. The key factor remains the brewing method.
How much does unfiltered coffee raise cholesterol levels?
The exact amount varies significantly based on the individual, the specific brewing method, and the quantity consumed. While studies confirm a clear and measurable increase in LDL (“bad”) cholesterol from drinking unfiltered coffee regularly, they don’t provide a single universal number. The effect is significant enough that health authorities advise switching to filtered methods if cholesterol is a concern.
Does coffee itself contain cholesterol?
No, coffee contains zero cholesterol. Cholesterol is a substance found only in animal products. The issue is that coffee contains the diterpene compounds (cafestol and kahweol) that can signal your liver to produce more LDL cholesterol than it otherwise would, thereby raising your blood cholesterol levels.
Does coffee affect a cholesterol test?
Yes, it can. Since drinking unfiltered coffee can temporarily increase your LDL cholesterol levels, consuming it shortly before a blood draw could potentially skew your results higher. It is always best to follow your doctor’s specific instructions for fasting and beverage consumption before a lipid panel test to ensure an accurate reading.
Are the add-ins like cream and sugar worse than the coffee itself?
For many people, yes. Ingredients like heavy cream, butter, and whole milk are high in saturated fat, which is a primary dietary driver of high LDL cholesterol. Sugary syrups contribute to weight gain, another risk factor. For someone drinking filtered coffee, the high-fat, high-sugar additions are almost certainly a greater threat to their cholesterol levels than the coffee itself.
Final Summary: How to Drink Coffee Without Harming Your Cholesterol
The verdict on the can coffee cause high cholesterol question is refreshingly clear: your brewing method is everything. You do not need to give up coffee to protect your heart health. By understanding the role of diterpenes and the power of a simple paper filter, you can easily mitigate the risks while continuing to enjoy the rich flavor and significant health benefits that coffee offers.
This advice, based on a synthesis of numerous scientific studies and guidance from health authorities, puts you back in control of your coffee cup. The key takeaways are simple and powerful:
- Always Choose Filtered: Make paper-filtered drip coffee or pour-over your default brewing method. This one change virtually eliminates the cholesterol concern.
- Limit Unfiltered Brews: Enjoy French press, espresso, and boiled coffee as an occasional treat rather than a daily habit, especially if you have high cholesterol.
- Watch Your Add-ins: Be mindful of cream, sugar, and butter. These can add significant amounts of saturated fat and calories, undermining the benefits of choosing a healthier brew.
Armed with this knowledge, you can now make a simple change to your coffee routine to protect your heart health. Time to grab a paper filter
