The internet is filled with information on health topics, much of it unsourced. When it comes to your health you don't want to trust a poorly-researched answer. Examine.com takes the most common health and nutrition questions and answers them by accumulating research and studies to give you the best answer currently available.
Not sure if eggs are healthy, or if the American evil that is high-fructose corn syrup will do more harm than regular sugar? Examine.com compiles the research to answer common questions like these. You can browse or search the site to find the answers you're looking for, or ask a question of your own. You should, of course, consult your doctor before making any significant changes that affect your health, but if you want a solid scientific opinion this is a good place to find it.
