The Internet has become a quick, easy method of searching for health-related information, but how can you know that what you’re finding is credible? As a rule, health-related sites sponsored by the U.S. government (Web addresses ending with “.gov”), not-for-profit health or medical organizations (ending with”.org”) and university medical centers are among many reliable sources of health information on the Web. You can also look for the red and blue “HON” seal, which means that a site meets certain standards set by the Health On the Net Foundation.
