Another great health resource is Dr. Joseph Mercola. His articles often read like something from Dr. Phil and he does sell products on his web sites; however, nearly every blog post has a place for comments and discussion and there are sometimes dissenting opinions (that don't get deleted). There is a huge volume of information on the site and I always skim through the comments to get all sides of the story. Dr. Mercola also references the research that his opinions are based on in most cases; in the rare instances that research isn't noted I just try to use good judgment or talk to my doctor depending on the risk involved. A vast majority of the articles are about proper diet and nutrition and this is probably the most important factor in a person's health.
