| In the News: Tea and Coffee Consumption and MRSA Nasal Carriage An estimated 2.5 million persons (1.4% of the population in the U.S.) are MRSA (methicillin-resistant Staphylococcus Aureus) nasal carriers. Consumption of hot coffee or tea was found associated with a lower likelihood of MSRA nasal carriage and potential MESA infection. The odds of MRSA nasal carriage were lower for those drinking both beverages. The mechanisms await further studies and elucidation, for coffee it is attributed the potential antibacterial properties of trigonelline, glyoxal, methylglyoxal and diacetyl; and for tea, tannic acides and catechins. Additionally, both tend to decrease iron absorption, and iron is critical to Staph aureus growth. In addition, other studies have shown benefits with the use of green tea for debridement of MSRA-infected decubitus ulcers and nebulized green tea catechin extracts in decreasing MSRA in the sputum of elderly patients with cardiovascular disease. There was not statistical siginificant relationship with iced tea or soft drink consumption. The failure of iced tea to show similar benefits has been conjectured to lower levels of polyphenoli compounds compared to hot tea. Other factors considered were the volatile antimicrobial compounds in the vapors reaching the nostrils when drinking hot coffee or tea and the possible benefits of higher nostril temperature to immune response.

| In the News: Coffee Consumption Improves Markers of Inflammation and Oxidative Stress Another study points to the beneficial effects of coffee consumption. Researches showed drinking coffee improved markers of subclinical inflammation and oxidative stress, as well as as increase in HDL cholesterol, the "good" cholesterol in the lipid profile. Although previous studies have shown possible protective benefits against T2DM, the study found no effects on glucose metabolism. (Heartwire CME / CME Author Laurie Barclay, MD) |
| In the News: High Coffee/Decaf/Tea Intake Linked to Lower Diabetes Risk Meta-analysis results showed high intakes of coffe, decaff coffee and tea are associated with a reduced risk for type 2 diabetes. Coffee consumption was reported to be inversely related with type 2 diabetes risk – every additional cup of coffee a day was associated with a 7% decrease in excess risk for diabetes. Although the study had limitations, the implications would be significant if the benefits are observed in interventional trials. (Laurie Barclay, MD / Medscape Medical News/ Dec 14, 2009) |
| In the News: Cup of coffee a day lowers risk of high BP A Japanese study on 4,554 men, age range of 20-70, reports that drinking a cup of coffee or two a day lowers the risk of high blood pressure. Those who drank no coffee had a higher incidence of hypertension. The benefit was attributed to chlorogenic acid, a polyphenol found in coffee, considered to have an expanding effect on blood vessels. Another Japanese study reports a cup of coffe a day halves the risk of colon cancer among women. |

the News: Coffee Boosts Stroke Risk, Study Finds Another bit of news to add to the "coffee paradox." A cup of coffee can increase the risk for ischemic stroke, particularly among infrequent drinkers. A study found a 2-fold increase risk for stroke in the hour after drinking a cup of coffee. There was no increase in risk in the hour after a cup of caffeinated tea or cola. Although coffee contains other substances, "caffeine if the most likely candidate pulling the trigger." The study was published in Neurology.2010;75:1583-1588.

Decaf Coffee. . . Not! Same outlet Starbucks decaf espresso and brewed coffee contained 2.0-16.8 mg/shot and 12.0-13.4 mg per 16 oz serving. respectively. AS A POINT OF REFERENCE, AN AVERAGE CUP OF BREWED COFFEE CONTAINS 135 MG OF CAFFEINE; AN AVERAGE CUP OF TEA, 50 MGS. Although the math might suggest it will take 10 cups or more of faux-decaf to get the equivalent caffeine in a cup of regular brew, there are patients specially sensitive to the effects of caffeine who gets buzzed and charged at much lesser caffeine concentrations.
