Nutrition Sources You Can Trust

**It's a challenge to keep this list up to date, so if you have a nutrition or health question you can now search all of the sources listed below plus 2,000+ more sites and articles at once using the search engine.

One of the questions I get asked the most is where to turn for reliable sources of nutrition information. Well, from now on I will have this handy guide to direct them to. I’ve broken it down into categories so you can browse depending on what you are looking for. To make this list, the vast majority of the dietary information published must be based on quality scientific evidence. No one can be 100% accurate 100% of the time, but you must be handing out valid information on nutrition for at least ~90-95% of your content to remain on the list. The sources listed here:

  1. Regularly discuss topics within the full context of available data
  2. Do not cherry-pick their sources and include those that may challenge their beliefs
  3. Interpret relevant clinical trials accurately and take into account their limitations
  4. Frequently cite valid and credible sources

In my opinion, those listed below meet the above criteria and promote high-quality science-based information.

Always keep in mind that no one person is beyond reproach and that you should think critically about everything you read, even if they are on the Good Sources list. This directory is fluid and will be edited as new reliable sources emerge. If you have one you think should be on here, drop it in the comments section. 

For the list of nutrition sources you should be wary of, head on over to this page. In that post, we also discuss how to check any source that may appear on either of these lists. 

Note: Nobody paid or in any way compensated me to be on this list.

Full disclosure: I do research for, which is not affiliated with this blog in any way.
