Coffee is a powerful stimulant due to its high caffeine content and has been a popular drink for centuries. It’s often touted as one of the healthiest beverages you can consume. But is this true?
There are many conflicting reports about whether coffee is good or bad for your heart and cholesterol levels. To help you make an informed decision, here is the latest research on how coffee affects cholesterol heart health.
A new study has revealed interesting insight into how caffeine interacted with particular cellular compounds to remove cholesterol from the bloodstream. While its stimulating effects have long been known, researchers have uncovered how caffeine benefits cholesterol levels.
The two particular compounds that caffeine interacted with were:
- Proprotein convertase subtilisin/Kexin type 9 (PCSK9) – is a protein that helps regulate the amount of cholesterol in the bloodstream.
- Sterol regulatory element-binding protein 2 (SREBP2) – is a potent activator of genes involved in cholesterol synthesis and transport.
Per worldwide statistics, the average coffee drinker consumes three 200 ml. (or about 7 oz.) cups of coffee per day. Coffee drinkers ingest up to 600 mg of caffeine per day, depending on the type of coffee used.
In a recent scientific review examining three extensive, prominent heart disease studies, the researchers using Machine Learning Analysis discovered that drinking one or more cups of caffeinated coffee was associated with decreased heart failure risk.
Nevertheless, scientists were never able to determine how caffeine protected the heart. But this new study has solved the puzzle.
The Mechanism Used By Caffeine To Lower Cholesterol
The new study found that when caffeine enters your body, it triggers a molecular chain reaction that lowers LDL cholesterol in the blood—LDL is the “bad” cholesterol. High levels of LDLs are linked to an increased risk of cardiovascular disease.
Notably, caffeine works by decreasing PCSK9 levels in your blood. As mentioned earlier, PCSK9 is a protein that helps regulate the amount of cholesterol in the bloodstream. High levels of it reduce the liver’s ability to clear excess cholesterol.
According to the researchers, a decrease in PCSK9 allows the liver can work more efficiently at removing the overabundance of cholesterol from the blood.
In addition, the study showed that caffeine was able to inactivate SREBP2. As mentioned earlier, SREBP2 is “a potent activator of genes involved in cholesterol synthesis and import.”
SREBP2 increases PCSK9 activity and transports it throughout your bloodstream. Inactivating it lowers excess cholesterol production and transport. And caffeine does precisely that.
Top Two Country Drinking The Most Coffee Have The Largest Drop In Cholesterol Levels
Finland is the nation with the highest per capita consumption of coffee in the world. They consume 26.5 pounds of coffee per capita, and each Finn consumes 12 pounds per year. Second place is Norway, with 21.8 pounds per capita.
You might be questioning what the relevance to cholesterol concerns these two countries. A report published in July 2019 in the International Journal of Epidemiology showed that since 1980 these two countries had the most significant decline in cholesterol.
It could be due to other factors. However, the connection to being the top 2 nations with the highest coffee consumption cannot be ignored, especially with the new landmark study that shows caffeine lowers LDLs (the bad cholesterol).
Many Finns drink as much as 8 or 9 cups of coffee per day. They get plenty of caffeine in their systems.
Similar results in Norway. 80% of its population drinks coffee, and the average number of cups per person is four daily. Both of these countries are obsessed with coffee. It is embedded in their cultures.
Is it a coincidence that they have the most significant drop in cholesterol levels? This cannot be a coincidence. There is an apparent causal connection here. High caffeine consumption/ largest decrease in cholesterol.

New research shows that caffeine found in coffee can decrease your cholesterol levels. Mainly your low-density lipoproteins (LDLs). High LDL levels lead to a buildup of cholesterol in your arteries.
The two nations with the highest consumption of coffee also have the highest decline in cholesterol levels.
You don’t need to drink 8 or 9 cups of coffee per day as they do in Finland. However, to help your cholesterol, you can drink two to three cups per day to reap the caffeine’s benefits on your cholesterol.
It is advisable not to add sugar or any fatty substance to the coffee because it may not help your cholesterol levels.
Always speak to a medical provider before trying this coffee regimen.
