What about two cups of filtered coffee every day with that oatmeal. Coffee has historically been a confusing story—originally linked to bladder and ovarian cancer, but that was just because coffee drinkers tended to be smokers. Coffee may cause heartburn and worsen osteoporosis, but maybe protect against diabetes, parkinsons, and Alzheimers. To sip or not to sip, what do you say, based on the latest research? How many say harmful??? Harmless??? Helpful??? Based on the latest science, helpful. Note this is for filtered coffee, though. There are some substances in coffee that raise your cholesterol, but they’re filtered out in the paper, so brewed coffee is ok, but something like plunger coffee or expresso may not be.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring watch the above video. This is just an approximation of the audio contributed by Dianne Moore.

    Hi Dr. Greger,
    I am glad to hear that coffee is helpful! Does the literature indicate any differences between hot brewed coffee and cold brewed coffee? I have read that hot brewed coffee is more acidic than cold brewed coffee.
    Thank you!

    Does it matter if the coffee is roasted or not? How does that affect its healthy-ness?

    Here is very interesting post
    http://www.idigmygarden.com/forums/archive/index.php/t-33232.html

    If you drink coffee 3 cuts a day, it raises
    homocysteine in by 1.26 mumol,

    but with 200 mg folic acid it reduces it below level of the non-coffee drinkers by 0.17 mumol

    Have you seen the new ‘weight loss holy grail’ or Garcinia Cambogia? I am skeptical on this substance that has been promoted as a breakthrough in the world of dieting.

      it is represented as the ‘all star’ supplement in javita coffee

    What about the claim that coffee destroys the nerves? Are there harmful natural chemicals in the coffee bean?

    As someone who has had intermittent cold sores my whole life, I am wondering what research might show about prevention and treatment. I took lysine daily years ago, until I read that it can increase cholesterol. Now, I use it topically and take it as a supplement only when I feel a fever blister coming on. Curiously, my dad and I got them; my mom, brother and son have never had them.
