Coffee has also been studied extensively for its role in fighting cancer development. Coffee has been associated with a reduced risk of cancer of the colon, mouth, esophagus, liver, prostate and breasts. In one study published by the Journal of Agriculture and Food Chemistry, researchers found that coffee significantly reduced the risk of developing colon cancer. In particular, they linked it to an antioxidant that is found exclusively in roasted coffee, known as methylpyridinium.
In another longitudinal study, Dr. Gang Hu and associates at the University of Helsinki found that moderate to heavy coffee drinkers were significantly less likely to develop liver cancer. They found that the antioxidants in coffee had a neutralizing effect against a specific liver cancer-causing enzyme known as gamma-glutamyltransferase.
Dental Cavity Protection
Coffee has amassed a negative reputation in relation to teeth because it can sometimes cause stains. On the other hand, recent scientific studies have revealed that it may actually help protect teeth from developing cavities, also known as dental caries. Beverages like coffee and tea contain a powerful astringent polyphenol known as tannin. The tannins found in coffee are effective enough to kill and neutralize the bacteria associated with cavity production.
In a recent study, Dr. Anila Namboodiripad and associates at the KLE Society’s Institute of Dental Science found that coffee was extremely effective at killing a range of micro-organisms associated with the formation of dental caries.
