For every study that focuses on harmful health effects of caffeine, it seems there's one that supports the health benefits of coffee. Today's study, from Mayo Clinic, finds that coffee may lower the risk of the devastating liver disease primary sclerosing cholangitis (PSC).


A study of the coffee habits of patients with PSC, primary biliary cirrhosis (PBC), and a control group of healthy people, found that people who were more likely to drink more coffee, and drink it more often, were less likely to have PSC.

There was no link found between coffee consumption and PBC, leading researchers to conclude that the two liver conditions differ more than initially thought.


"Moving forward, we can look at what this finding might tell us about the causes of these diseases and how to better treat them," said study author Craig Lammert, M.D., a Mayo Clinic gastroenterologist, in a press release.


Patients from 2002 to 2012 were asked to answer a coffee questionnaire. Overall there were 1,334 patients used -- 530 with PBC, 348 with PSC, and 456 controls. Most of the participants were female.


On average, patients with PSC had 50 cups of coffee per month, and were coffee drinkers for approximately half of their lives. Patients without PSC or PBC claimed they drank an average of 78 cups per month, and were coffee drinkers for nearly two thirds of their lives.


Coffee and caffeine have also shown benefits for protecting the liver from the harmful effects of alcohol, and for perhaps providing an overall defense against liver damage.


Coffee's Hidden Health Benefits


Caffeine isn't always good for you, but recent studies have shown that the right amount of coffee can actually make you healthier:


- Take Your Coffee With Some Milk and Beer. Heavy coffee consumption has been shown to protect alcohol drinkers by decreasing enzyme activity and improving liver protection, according to research from the University of Tampere in Finland. The news is especially good for men, who saw the greatest decrease in gamma-glutamyltransferase levels when drinking nearly as much coffee as alcohol.

"Our findings suggest a possible protective effect for coffee intake in alcohol consumers," study researcher Onni Niemelä, of Seinäjoki Central Hospital and the University of Tampere, told Live Science.


- Coffee Breaks Reduce Stroke Risk. A study of 83,000 daily coffee or tea drinkers showed a reduced stroke risk of approximately 20 percent. These people were specifically protected from hemorrhagic stroke.


- Cheer Up, With Coffee. While other caffeinated drinks, like diet soda, have been linked to depression, coffee might actually lower your risk. Coffee drinkers are about 10 percent less likely to develop depression.


But that's not all. Coffee has also been shown to help with heart disease, breast cancer, stress, cavities, and Parkinson's Disease.

  • Coffee (Or At Least, The Caffeine!) Can Help You Proofread Better


    The caffeine in coffee could actually help you to <a href="http://psycnet.apa.org/psycinfo/2011-23154-001/" target="_hplink">spot grammar errors</a>, according to a new study in the <em>Journal of Experimental Psychology</em>.

  • Coffee Could Lower Women's Depression Risk


    Women who drink a few cups of <a href="http://www.huffingtonpost.com/2011/09/27/coffee-cuts-depression-women_n_982122.html" target="_hplink">caffeinated coffee have a lower risk of depression</a> than women who don't drink any coffee, according to a Harvard study.

    That research, published in the <em>Archives of Internal Medicine</em>, shows that women who drink two to three cups of coffee a day have a 15 percent lower risk, while women who drink four or more cups of coffee a day have a 20 percent lower risk.

    Study research Dr. Albert Ascherio <a href="http://www.huffingtonpost.com/2011/09/27/coffee-cuts-depression-women_n_982122.html" target="_hplink">told HuffPost</a> earlier that "caffeine is known to affect the brain," because it "modulates the release of mood transmitters."

    "I'm not saying we're on the path to discovering a new way to prevent depression," he said. "But I think you can be reassured that if you are drinking coffee, it is coming out as a positive thing."




  • Coffee Could Save Your Brain


    ... Well, maybe. A study in the <em>Journal of Alzheimer's Disease</em> suggests that there's something in coffee -- though researchers have yet to determine what exactly that "something" is -- interacts with caffeine to boost the levels of granulocyte colony stimulating factor (GCSF), a growth factor that seems to be able to <a href="http://www.huffingtonpost.com/2011/06/24/coffee-could-ward-alzheimers_n_882931.html" target="_hplink">fight off Alzheimer's disease in mice</a>.

    The amount of coffee needed in the study is equivalent to about four or five cups of coffee for humans.

    Researchers said <a href="http://www.j-alz.com/press/2011/20110621.html" target="_hplink">GCSF likely has this effect</a> because it causes stem cells in the bone marrow to come into the brain and remove the beta-amyloid plaques associated with Alzheimer's disease. It also has a role in forming brain cell connections and creating new brain neurons, researchers said.




  • Coffee Could Lower Men's Prostate Cancer Risk


    A Harvard School of Public Health study shows that men who drink six cups of coffee a day have a 60 percent decreased <a href="http://www.huffingtonpost.com/2011/05/18/coffee-can-cut-prostate-c_n_863472.html" target="_hplink">chance of developing a dangerous form of prostate cancer</a>, as well as a 20 percent decreased chance of developing any other kinds of prostate cancer.

    The study, published in the <em>Journal of the National Cancer Institute</em>, also shows that just <a href="http://jnci.oxfordjournals.org/content/early/2011/05/17/jnci.djr151.abstract" target="_hplink">drinking just some coffee a day</a> -- just one to three cups -- could still cut prostate cancer risk by 30 percent.




  • Coffee Could Ward Off The World's Most Common Cancer


    New research presented at the American Association for Cancer Research conference shows that coffee could help to <a href="http://www.huffingtonpost.com/2011/10/24/coffee-most-common-cancer_n_1025089.html" target="_hplink">ward off basal cell carcinoma</a>, the most common cancer in the world.

    Researchers from Brigham and Women's Hospital and Harvard Medical School found that women who drink three or more cups of caffeinated coffee a day have a 20 percent lower risk of the skin cancer, while men had a 9 percent lower risk.

    Decaf coffee didn't seem to have the same protective effect -- so "our study shows that the inverse association with BCC appears due to caffeine, not other components in the coffee consumption," study researcher Fengju Song, Ph.D., earlier <a href="http://www.huffingtonpost.com/2011/10/24/coffee-most-common-cancer_n_1025089.html" target="_hplink">told HuffPost</a>.




  • Coffee Could Protect You From Type 2 Diabetes


    Drinking coffee is associated with a <a href="http://archinte.ama-assn.org/cgi/content/abstract/169/22/2053" target="_hplink">lower Type 2 diabetes risk</a>, with more coffee consumption linked to a greater decrease in risk, according to an <em>Archives of Internal Medicine</em> review of studies from 2009.

    In that review, researchers looked at data from more than 450,000 people in 18 studies, and found that for every extra cup of coffee drank a day, a person's risk of Type 2 diabetes decreased by 7 percent.

    However, researchers cautioned that "the putative <a href="http://archinte.ama-assn.org/cgi/content/abstract/169/22/2053" target="_hplink">protective effects of these beverages</a> warrant further investigation in randomized trials."




  • Coffee Could Decrease Parkinson's Risk


    Drinking <a href="http://www.ncbi.nlm.nih.gov/pubmed/20182023" target="_hplink">a few cups of coffee a day</a> could lower the risk of developing Parkinson's disease by as much as 25 percent, according to a study published last year in the <em>Journal of Alzheimer's Disease</em>.

    In that review of studies, which was published in the <em>Journal of Alzheimer's Disease</em>, researchers examined 26 studies that involved 125,000 British people, to find that <a href="http://www.telegraph.co.uk/health/healthnews/7815087/Coffee-can-cut-chances-of-developing-Parkinsons-disease-according-to-new-research.html" target="_hplink">two or three cups of coffee</a> seemed to have the optimal effect, <em>The Telegraph</em> reported.
