Coffee And Health: Beverage Doesn't Raise Risk Of Heart Disease Or Cancer, Study Finds
Finding it impossible to kick your java habit? It might be just fine to keep your morning cup around.
A new study in the American Journal of Clinical Nutrition shows that regularcoffee-drinkers don't have an increased risk of diseases like heart disease and cancer, and they also have a lower risk of Type 2 diabetes compared to sporadic drinkers or non-drinkers, Reuters reported.
"Our results suggest that coffee consumption is not harmful for healthy adults in respect of risk of major chronic disease," study researcher Anna Floegel, an epidemiologist at the German Institute of Human Nutrition Potsdam-Rehbruecke, told Reuters.
The study included 42,659 people who participated in the European Prospective Investigation into Cancer and Nutrition (EPIC)–Germany study. The researchers had the study participants record how frequently they ate the different foods in their diets (including coffee), and they also collected information on whether the study participants had any chronic diseases.
After almost nine years, the researchers found that the people who drank four or more cups of coffee a day were at no higher risk for chronic disease, compared with those who drank less than a cup of coffee a day, according to the study.
Daily Glow pointed out that the coffee-drinkers actually had a 23 percent lower risk of Type 2 diabetes than the non-coffee drinkers.
The Mayo Clinic reported that past studies on coffee that showed a possible link with disease likely didn't account for factors like smoking and being sedentary, which may have been popular lifestyle characteristics for coffee-drinkers when the research was conducted.

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 grammatical errors</a>, according to a new study in the <em>Journal of Experimental Psychology</em>. Researchers found that <a href="http://bodyodd.msnbc.msn.com/_news/2011/10/26/8498728-tank-up-on-java-unleash-your-inner-editor-says-study?ocid=twitter" target="_hplink">caffeine helped students to correct errors</a> in subject-verb agreement and verb tense, MSNBC reported. However, the caffeine still didn't seem to make a difference at identifying misspelled words -- sorry.
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.
