Nutrition Sources You Should Avoid

**Need to quickly fact check a source or claim? Try using the NutriSearch.info search engine. All search results only come from 450+ websites that deliver accurate, evidence-based content.

The internet is a cesspool of god awful nutrition advice. Some of this terrible information is delivered in such a way that makes it seem legitimate and can fool even the most intelligent among us. I created this guide as a resource to help cut through the hype you see in media headlines and on your Facebook feed. If you see an article/book/talk/product from one of the sources below please proceed with caution as it may be a load of nonsensical, pseudoscientific rubbish (especially if it's from The Food Babe). 

To land a spot on this list, a significant portion of the dietary information provided by the source must be scientifically erroneous or misleading. Some of these sources fall into the category of "quacks, frauds, and charlatans" and while others are in the "questionable" category. The common pitfalls I've seen in these sources can be grouped into four general categories:

  1. Cherry-picking sources that agree with their beliefs while ignoring those that don't.
  2. Not interpreting data within the full context of what is known about a topic.
  3. Over-extrapolating study results (like saying that findings from an animal trial apply directly to humans).
  4. Citing invalid or uncredible sources (using anecdotes as hard evidence as opposed to peer-reviewed literature).

Overall, the theme of this list are people who have misconstrued nutritional science. In my opinion, the sources below meet one or more of these criteria. 

Some of you are bound to see people on here that you consider to be good resources or may even like. Their appearance on this list does not mean everything they have ever published is erroneous, simply that they have also published too much unsound material to be considered a reliable nutrition information source as defined in my Good Nutrition Sources post.

How to Fact Check a Source

By no means is this a comprehensive list as new dubious sources pop up frequently. If you are attempting to determine the reliability of a source that is not listed, here are a few options to try. First, head on over to QuackWatch.com. If they are on that site, it’s probably best to steer clear. A second option is to take the name of the person in question and search it in google (or on NutriSearch) followed by one of these phrases/words: “debunked”, “critique”, “fact check”, “quack”, or “fraud”. You may be able to get some useful articles using this second method. Don’t be afraid to try and find out if they have any reliable credentials as well. Do they have relevant degrees or respected certifications in the field of nutrition such as those listed on the Good Sources page? If not, you may want to view what they’re saying with some skepticism until you can confirm it with a reliable source. 

For a list of reliable nutrition sources you can use, head on over to this page or try using the NutriSearch.info search engine. This list is fluid and will be edited as new unreliable sources emerge. If you have one you think should be on here, drop it in the comments section. 

Note: I don’t link directly to any of these sources (because why would I?). Instead, I’ve linked to resources demonstrating why they are on this list.

Because the titles "nutritionist" and "nutrition consultant" are unregulated in most states, they have been adopted by many individuals who lack recognized credentials and are unqualified. In addition, a small percentage of licensed practitioners are engaged in unscientific nutrition practices. The best way to avoid bad nutrition advice is to identify and avoid those who give it. I recommend steering clear of:

  • Anyone who says that everyone needs vitamin supplements to be sure they get enough. Most people can get all the vitamins they need by eating sensibly.
  • Anyone who suggests that most diseases are caused by faulty nutrition. Although some diseases are diet-related, most are not.
  • Anyone who suggests that large doses of vitamins are effective against a large number of diseases and conditions. That is simply untrue.
  • Anyone who suggests hair analysis as a basis for determining the body's nutritional state or for recommending vitamins and minerals. Hair analysis is not reliable for this purpose.
  • Anyone who claims that a wide variety of symptoms and diseases are caused by "hidden food allergies"
  • Anyone who uses a computer-scored "nutrient deficiency test" as the basis for prescribing vitamins. There are valid ways that computers can be used for dietary analysis. But those used for recommending vitamins are programmed to recommend them for everyone.
  • Be wary of those who sells vitamins in their offices. Unscientific practitioners often do sell unneeded supplements — usually at a considerable profit.
