We constantly search the internet for online medical information. Most medical journals are now online, doctors advice is available, tons of information on disease as well as prevention. Diabetes, dieting, excercise, its all online. Take advantage of this great asset but remember that everything you read is not always accurate. Check different sources and go with credible sites. I would believe Johns Hopkins site before Joe Blows geocities site on cancer prevention. As always, please check with your doctor before following any advice you find on the internet.
