IS Coffee: More Harmful or Helpful?
Aliso Viejo Weight Loss Says:
If you're a coffee drinker, you’ll be happy to know that more and more studies are suggesting that coffee (both caffeinated and decaffeinated) offers health benefits, including a reduced risk of Type 2 Diabetes (T2D), Parkinson’s and gall bladder disease. According to a study published in the Journal of the American Medical Association (JAMA), researchers found a link between drinking coffee and T2D. The study, conducted in Finland - where coffee consumption is higher than anywhere else in the world – found that diabetes risk among women drinking three to four cups a day decreased by 29 percent. In men, three to four cups decreased risk by 27 percent. A large epidemiologic study in the U.S (41,934 men and 84,276 women) confirmed the Dutch study findings and additionally found decaffeinated coffee consumption to reduce the risk of T2D. While caffeine increases energy expenditure and may be beneficial for maintenance of body weight/weight loss, studies consistently show it also decreases insulin sensitivity and impairs glucose tolerance.
Frank Hu, MD, PhD, an Associate Professor of Nutrition and Epidemiology at Harvard School of Public health and co-author of the U.S. study, explains why coffee reduces risk of T2D, "One reason is that coffee is not just caffeine. Coffee has large amounts of other ingredients, for example, antioxidants and minerals like magnesium. And those minerals and antioxidants actually are beneficial for blood sugar metabolism and insulin sensitivity." This could explain why decaffeinated coffee affects T2D risk as well as caffeinated.
