Is Your Coffee Habit Helping or Hurting Your Health?

Coffee has plenty of health benefits, but how you brew it could make a big difference.

Research suggests that unfiltered coffee may increase health risks—specifically heart disease. A 20-year study analyzing the coffee habits of over 500,000 adults found that those who drank unfiltered coffee had higher LDL cholesterol and a 10% greater risk of cardiovascular disease.

The Filtered vs. Unfiltered Debate

Filtered coffee, on the other hand, was linked to better health outcomes. Drinking one to four cups per day was associated with a 12% lower risk of death in men and a 20% lower risk in women compared to those who drank no coffee at all.

The issue with unfiltered coffee comes down to cafestol, a compound found in coffee beans that can raise LDL cholesterol by altering cholesterol metabolism. The highest levels of cafestol were found in French Press and boiled coffee, while espresso—despite being unfiltered—did not show the same effect.

Should You Change Your Coffee Routine?

While the research is observational, multiple studies suggest similar findings. If you regularly drink unfiltered coffee, consider limiting your intake or getting a blood test to see how it affects your cholesterol levels.
