The proportion of land used to cultivate shade grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996, according to a new study by scientists from Univ. of Texas at Austin and five other institutions.
The study’s authors say the global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities and individual farmers.
New research reveals that consuming two or more cups of coffee each day reduces the risk of death from liver cirrhosis by 66 percent, specifically cirrhosis caused by non-viral hepatitis. Findings in Hepatology, a journal published by Wiley on behalf of the American Association for the Study of Liver Diseases, show that tea, fruit juice and soft drink consumption are not linked to cirrhosis mortality risk. As with previous studies heavy alcohol use was found to increase risk of death from cirrhosis.
A 2004 report from The World Health Organization (WHO) estimates that each year 1.3 percent of total death worldwide is caused by liver cirrhosis. Previous research shows that 29 million Europeans have chronic liver disease, with 17,000 deaths annually attributed to cirrhosis. Further WHO reports state that liver cirrhosis is the 11th leading cause of death in the U.S.
University of California students who drink coffee to get through the day will soon be able to study the science behind the beverage.
This week UC Davis will host a research conference run by its recently founded Coffee Center. The center is currently without a dedicated home, but the university hopes to formalize the research in coming years and eventually offer a major in coffee science, The Sacramento Bee reports.
Coffee consumption reduces risk of hepatocellular carcinoma (HCC), the most common type of liver cancer, by about 40 percent, according to an up-to-date meta-analysis published in Clinical Gastroenterology and Hepatology, the official clinical practice journal of the American Gastroenterological Association. Further, some data indicate that three cups of coffee per day reduce liver cancer risk by more than 50 percent.
"Our research confirms past claims that coffee is good for your health, and particularly the liver," says Carlo La Vecchia, study author from the department of epidemiology, Istituto di Ricerche Farmacologiche Mario Negri. "The favorable effect of coffee on liver cancer might be mediated by coffee’s proven prevention of diabetes, a known risk factor for the disease, or for its beneficial effects on cirrhosis and liver enzymes."
Four Cups of Coffee a Day May Keep Cancer Recurrence Away
Coffee consumption is associated with a lower risk of prostate cancer recurrence and progression, according to a new study by Fred Hutchinson Cancer Research Center scientists that is online ahead of print in Cancer Causes & Control.
Corresponding author Janet Stanford, co-director of the Program in Prostate Cancer Research in the Fred Hutch Public Health Sciences Division, conducted the study to determine whether the bioactive compounds in coffee and tea may prevent prostate cancer recurrence and delay progression of the disease.
The world’s most expensive coffee can cost $80 a cup, and scientists now are reporting development of the first way to verify authenticity of this crème de la crème, the beans of which come from the feces of a Southeast Asian animal called a palm civet. Their study appears in ACS’ Journal of Agricultural and Food Chemistry.
Drinking several cups of coffee daily appears to reduce the risk of suicide in men and women by about 50 percent, according to a new study by researchers at the Harvard School of Public Health (HSPH). The study was published online in The World Journal of Biological Psychiatry.
“Unlike previous investigations, we were able to assess association of consumption of caffeinated and non-caffeinated beverages, and we identify caffeine as the most likely candidate of any putative protective effect of coffee,” says lead researcher Michel Lucas, research fellow in the Department of Nutrition at HSPH.
High above our planet in the realm of satellites and space stations, the familiar rules of Earth do not apply. The midday sky is as black as night. There is no up and no down. Dropped objects do not fall, and hot air does not rise.
Of all the strange things that happen up there, however, it is possible that the strangest happens to coffee. Physics professor Mark Weislogel of Portland State Univ. has given a lot of thought to coffee (and other fluids) in space, and he describes what happens.
Coffee ‘Miracle’ Weight-Loss Supplements Don’t Work
A major ingredient in those green coffee bean dietary supplements — often touted as “miracle” weight-loss products — doesn’t prevent weight gain in obese laboratory mice fed a high-fat diet when given at higher doses. That’s the conclusion of a first-of-its-kind study published in ACS’ Journal of Agricultural and Food Chemistry. It also linked the ingredient to an unhealthy build-up of fat in the liver.
Regular consumption of coffee is associated with a reduced risk of primary sclerosing cholangitis (PSC), an autoimmune liver disease, Mayo Clinic research shows. The findings were being presented at the Digestive Disease Week 2013 conference in Orlando, Fla.
PSC is an inflammatory disease of the bile ducts that results in inflammation and subsequent fibrosis that can lead to cirrhosis of the liver, liver failure and biliary cancer.
Green Coffee Beans Help Control Blood Sugar Levels
Scientists described evidence that natural substances extracted from unroasted coffee beans can help control the elevated blood sugar levels and body weight that underpin type 2 diabetes. Their presentation on chlorogenic acids ― widely available as a dietary supplement ― was part of the 245th National Meeting & Exposition of the American Chemical Society (ACS).
Joe Vinson, who led the research, pointed out that type 2 diabetes, the most common form of diabetes, is an increasing global health problem. In the U.S. alone, almost 26 million have the disease, in which the pancreas does not produce enough of the insulin that enables the body to use sugar, or cells resist the effects of that insulin. Blood sugar levels rise, increasing the risk of heart attacks, stroke and other health problems.
Long distance commercial drivers who consume caffeinated substances such as coffee or energy drinks, to stay awake while driving, are significantly less likely to crash than those who do not, even though they drive longer distances and sleep less, finds a study published online by British Medical Journal.
Long distance drivers routinely experience monotonous and extended driving periods in a sedentary position, which has been associated with wake time drowsiness, increasing the likelihood of crashing.
Used Coffee Grounds Are Chock-Full of Antioxidants
To plant food, insect repellant and other homespun uses for spent coffee grounds, scientists are adding an application that could make the gunk left over from brewing coffee a valuable resource for production of dietary supplements. Their new report in ACS’ Journal of Agricultural and Food Chemistry concludes that used coffee grounds are a rich source of healthful antioxidant substances.
Diet Soda Linked to Depression, Coffee Lowers Risk
New research suggests that drinking sweetened beverages, especially diet drinks, is associated with an increased risk of depression in adults while drinking coffee was tied to a slightly lower risk. The study was released and presented at the American Academy of Neurology’s 65th Annual Meeting in San Diego.
“Sweetened beverages, coffee and tea are commonly consumed worldwide and have important physical — and may have important mental — health consequences,” says study author Honglei Chen, with the National Institutes of Health and a member of the American Academy of Neurology.
Caffeinated Coffee Significantly Lowers Risk of Oral Cancer
A new American Cancer Society study finds a strong inverse association between caffeinated coffee intake and oral/pharyngeal cancer mortality. The authors say people who drank more than four cups of caffeinated coffee per day were at about half the risk of death of these often fatal cancers compared to those who only occasionally or who never drank coffee. The study is published online in the American Journal of Epidemiology. The authors say more research is needed to elucidate the biologic mechanisms that could be at work.
Previous epidemiologic studies have suggested that coffee intake is associated with reduced risk of oral/pharyngeal cancer. To explore the finding further, researchers examined associations of caffeinated coffee, decaffeinated coffee, and tea intake with fatal oral/pharyngeal cancer in the Cancer Prevention Study II, a prospective U.S. cohort study begun in 1982 by the American Cancer Society.
