Kresser advertises himself as a "health detective".Do You Need a Health Detective?. Chris Kresser. He lacks scientific education and admitted in 2019 that he does not know how to read forest plots.Joe Rogan Experience #1393 - James Wilks & Chris Kresser - The Game Changers Debate. youtube.com. More recently, Kresser has made pseudoscientific and unfounded claims about dietary supplements being effective nootropics.
==Irrational beliefs==
===Acupuncture===
Kresser is a fanatical acupuncture proponent who claims that it has the potential to cure disease. He has written that acupuncture "stimulates the body’s self-healing mechanisms. And the body’s ability to heal itself far surpasses anything western medicine has to offer." He provides no scientific evidence for this statement. The scientific consensus is that acupuncture is ineffective for a wide range of conditions.Ernst E (April 2009). "Acupuncture: what does the most reliable evidence tell us?". Journal of Pain and Symptom Management. 37 (4): 709–14. It has been impossible to find consistent evidence for acupuncture after more than 3000 trials.Acupuncture Doesn’t WorkFalse Claims for Acupuncture.
===Opposition to flu vaccination===
Kresser has received criticism from medical experts for his comments against flu vaccination. He dismisses any positive studies and promotes "natural" alternatives, such as bone broth, fermented cod liver oil, paleo diet and vitamin supplements.RHR: The Truth about Flu Shots (And What to Do Instead). Chris Kresser.
===Vitamin K injections===
Kresser argues against Vitamin K injections for newborns. He made the false statement that "Vitamin K injections have not been adequately tested for safety." In reality, the injections given at birth are safe and side-effects are incredibly rare.Are the Ingredients in the Newborn Vitamin K Shot Safe?That Black Box Warning on Vitamin K ShotsHere's The Truth About Vitamin K For NewbornsEvidence on: The Vitamin K Shot in Newborns. "Side effects from vitamin K injection given at birth are incredibly rare and if they are seen, they end up being case reports due to rarity. I could not find any case reports using the most recent version of vitamin K used in the U.S., in which the infant became severely ill or died from it."
===Cholesterol denialism===
Kresser is a cholesterol and statin denialist.The Diet-Heart Myth: Cholesterol and Saturated Fat Are Not the Enemy. Chris Kresser.The Truth about Statin Drugs. Chris Kresser.
Kresser is known for misleading people on cholesterol and saturated fat. He consistently misreads scientific papers, thus presenting false evidence in attempts to fool people into following his paleo diet. Kresser's statements about saturated fat are entirely unreliable. He is known to criticize epidemiological studies if they support plant-based diets but will cite epidemiology if it supports his own diet.
===DHA===
Kresser has made false and misleading claims about DHA (). On his website, Kresser claims without providing any evidence that "DHA comprises 60% of the brain".How to Supercharge Your Brain with Nootropics. chriskresser.com. In reality, DHA comprises 40% of the polyunsaturated fatty acids (PUFAs) in the brain and is 10-20% total lipids.Docosahexaenoic acid,22:6n-3: Its roles in the structure and function of the brain. sciencedirect.com. There is no evidence that 60% of the brain is DHA, and the claim is rather bizarre to make. It is possible that Kresser confused DHA with the total fat content of the brain as the human brain is about 60% fat.Brain Anatomy and How the Brain Works. hopkinsmedicine.org. "Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts". This is a good example why Kresser is not a trustworthy source of information for medical or science content, as he cannot even get basic information about the human body correct. As of November 2024 the false claim remains on his website. His website is obviously not fact-checked.
==Criticism==
Retired family physician and skeptic Harriet Hall has commented:
Kresser has also received criticism from those in the paleo community for his promotion of dairy products.Kefir Consumption Ill Founded at Best. thepaleodiet.com. Dairy is forbidden on the paleo diet because humans did not consume the milk of animals until after domestication. The earliest evidence of dairy is from the Neolithic of the seventh millennium BCE (roughly 9000 years ago).Humans have been using milk and dairy products for 9000 years Kresser advises against a strict paleo diet and has supported the consumption of kefir.Kefir: The Not-Quite-Paleo Superfood says Kresser's advice is ill-founded and unscientific.
===Nootropics pseudoscience===
On his website, Kresser has made unfounded health claims that dietary supplements such as citicoline, lion’s mane mushroom, phosphatidylserine, Bacopa monnieri, Ginkgo biloba, uridine monophosphate and Alpinia galanga are effective nootropics (have cognitive-enhancing effects).Consumer Health Digest, Issue #24-25. quackwatch.org. There is no good clinical evidence to support what Kresser claims, most of what he cites is either from unreliable rodent studies or from limited preliminary studies. Katie Suleta of the American Council on Science and Health has noted:
==2019 embarrassment==
===Debate with James Wilks===
In 2019, Kresser debated over claims made in the plant-based documentary The Game Changers on Joe Rogan's podcast. Kresser greatly embarrassed himself by making entirely false claims such as cattle are not fed b12 supplements and not remembering studies he had cited in his own ebook. Kresser also commented that he does not know how to read forest plots.Chris Kresser Forest Plot Joe Rogan Clip ft. James Wilks. youtube.com. 
Kresser lost much support over the debate, even from his own followers.
