A number of observational and population studies suggest that drinking a moderate amount of coffee may reduce the risk of cardiovascular disease. However, high daily intake of unfiltered coffee (such as French press, Turkish coffee and espresso) may increase levels of bad cholesterol — and not because of coffee additives, such as milk, creamer or sugar.

Would coffee made from the Keurig machine also raise cholesterol in the same way as unfiltered coffee? Seems like it would, but this is not mentioned in the article. Thanks.

I clicked on the article link, but the details are scarce. I wanted to determine if the study accounted for what trial participants may have added to their coffee, assuming that participants are honest about the additives. I can understand that adding unhealthy fats, such as cream, and possibly also sugar, would definitely raise LDL and triglyceride levels. On the other hand, I just add almond milk and Stevia. Dr. Cooperman, please let me know if you have more details in this regard, because I'm a worrier. Much Thanks!

Hi Deborah - great question! We've reviewed the individual studies cited in the analysis and have updated our full answer above to explain whether coffee additives such as milk, creamer or sugar may have influenced the results.

Regarding the recent Chinese analysis showing that heavier coffee consumption is associated with higher cholesterol: Do you know how a "cup" was defined? At least in the US, if you mention a "cup of coffee" the thought these days is of, say, a generous mug, which can be far larger than traditional "coffee cups," or than what you will be served if you request a "cup" of coffee in many other countries. This definition can greatly change one's practical takeaway from the study.

Hi Richard, great points! We've added information related to your comments - including how a "cup" was defined and how this volume compares to a typical mug - to the answer above.

I believe the way coffee is brewed has a direct result on LDL levels. Specifically, coffee that is brewed with a paper filter via drip versus percolated has a negligible effect on LDL. Apparently, the paper filter captures the coffee oils which are responsible for the modest effect on LDL.

I have read that coffee (caffeine?) can be a big problem ( or one cause) for acid reflux.

I used to drink up to five mugs of coffee a day. At the age of 70 I started to have an irregular heart beat. Meaing my heart would miss a beart or two and then douible up the next beats. This caused an uncomfortable feeling in my chest and neck. I went to my doctor and I ended up doing a stress test with a cardiogram, etc. The conclusion was to cut way back on the caffiene Result, the irregular heart beats stopped. Now I drink decaffineated coffee.
