So it might be surprising to learn that when it comes to the trustworthiness of health and medical information on the Web, the collective wisdom gets flipped on its head. The best health sites are those offered by the federal government. The information is clear and well-organized. Academic sites can be quite good, though they generally don't have the scientific depth of their government counterparts.
Commercial websites are a mix of excellence and exploitation, equally capable of help or harm.
One of the best sites for comprehensive health information is healthfinder, a project of the U.S. Department of Health and Human Services. With a review panel to ensure high quality, medical websites are eager to be included in healthfinder's listings. For people recently diagnosed with cancer, for example, healthfinder has information on relevant clinical trials. For asthma sufferers, there are the latest guidelines for managing the disease. Studies are dated and attributed to assure their currency and credibility.
