caffeine-infused beverage yerba mate probably causes cancer, the World Health Organization announced Wednesday.<br \/>\nBeverages surpassing 149 degrees Fahrenheit (65 degrees Celsius) may increase the risk of tumors in the esophagus, which resides in the chest area below the throat, according to USC\u2019s Mariana Stern and 22 other scientists from 10 countries. They met at the WHO\u2019s International Agency for Research on Cancer in Lyon, France, in May to determine if drinking coffee, mate or other very hot beverages causes cancer. Their results were published in the journal\u00a0<em>Lancet<\/em>\u00a0on June 15.<br \/>\n\u201cEnjoy your coffee or mate, but make sure it\u2019s not very hot,\u201d said Stern, an associate professor of preventive medicine and urology at the Keck School of Medicine of USC. \u201cThere is physical evidence that very hot beverages can contribute to cell injury in the esophagus and thus contribute to cancer formation.\u201d<br \/>\nThe group scoured more than 1,000 studies on over 20 different types of cancer.

The temperature varies between 99-190 degrees Fahrenheit (37-88 degrees Celsius), Stern said.<br \/>\n\u201cWe were now able to evaluate more carefully the effect of mate itself from the effect of temperature, and we concluded that the observed links between mate drinking and cancer of the esophagus seem to be largely driven by drinking mate very hot,\u201d Stern said. \u201cSimilar associations are seen for other very hot beverages, like tea or coffee.\u201d<br \/>\nStern and her colleagues noted that drinking yerba mate at very high temperatures \u2013 between 150 and right below the boiling point of 212 degrees Fahrenheit (66-100 degrees Celsius) \u2013 is common practice in certain countries in South America, including Argentina, Uruguay and Paraguay.<br \/>\n<strong>A cup of coffee a day may keep liver cancer away<\/strong><br \/>\nThe scientists downgraded a cup of joe from \u201cpossibly carcinogenic\u201d and hot mate from \u201cprobably carcinogenic\u201d to safe for consumption as long as neither are scalding hot.<br \/>\nIn 1991, the WHO gave coffee that classification based on a much smaller database of studies. Now, the scientists highlighted some studies that associated coffee with cancer when the real culprit was probably tobacco smoking, which is highly correlated with heavy coffee drinking, according to the report.<br \/>\nLate last year, Stern participated in a WHO group that concluded consuming processed meat \u2013<a href=\"https:\/\/urldefense.proofpoint.com\/v2\/url?u=http-3A__universityofsoutherncalifornia.cmail19.com_t_j-2Dl-2Dktquyd-2Dmttnpjl-2Dq_&amp;d=DQMFaQ&amp;c=clK7kQUTWtAVEOVIgvi0NU5BOUHhpN0H8p7CSfnc_gI&amp;r=krxc5bbUwNh8e3q5sUEfLtqETcHYzxI0-EShImMR2_0&amp;m=jkcKCsteUruDjkBVE24MLI23vzqdav-hcKk7lj0qX84&amp;s=iuWGSo9_1j3PzOKHI1RbE-u9BWa3V1cFQHharjwSxzY&amp;e=\">bacon, salami, sausages, hot dogs and deli meats \u2013 causes cancer<\/a>.<br \/>\nHowever, the news about coffee was not grim. The researchers estimate that a cup of coffee a day decreases the risk of liver cancer by 15 percent. In other words, the scientists are giving coffee lovers a free pass to drink as much coffee as their bladders can handle.<br \/>\n\u201cFor many cancer types, we found clear evidence that coffee is not carcinogenic,\u201d Stern said. \u201cIn fact, we found that coffee protects against some cancers such as liver and uterine endometrium cancer.\u201d<\/p>\n\n\n\n<\/div>\n  <\/div>\n\n\n
