RFK Jr. said this diet could 'cure' mental illness. Here's a fact check.

Doctors told HuffPost that Kennedy isn't necessarily all wrong in his claims, but there is way more to the story. Here's what to know:

Kennedy's comments align with the ideology his "Make America Health Again" campaign promotes, "which is 'natural' is better for your health," said Nicole Lippman-Barile, a clinical psychologist.

Kennedy has a history of demonizing medications like antidepressants, making statements claiming that they are more addictive than heroin and that they contribute to violent behavior, which is not proven. 

There is ongoing research into the role nutrition plays in mental illness, but any claims that keto is a "cure" are way overstated. 

Dr. Brooke Resch, a psychiatrist in Minnesota, said in an Instagram video that there is some evidence that suggests a keto diet may be beneficial in a mental health treatment plan, but there is not "a ton at this point" to support that.

Palmer, whom Kennedy likely referenced in his speech, has explored the potential impact of the keto diet on mental illnesses like bipolar disorder and schizophrenia, but Lippman-Barile said his research is often made up of very small sample sizes or only covers short periods of time, like a few weeks or months.

"We also have no long-term studies looking at the keto diet and what that does for mental illness," she said.

"Even the most recent research that [Kennedy's] citing in this speech here says these exact same things ― that it's too soon to have this as a clinical recommendation" 


Kennedy got his post by supporting Trump, but he has always seemed like an oddball to me.
