Kennedy Jr’s statement probably referred to the Harvard psychiatrist Dr Christopher Palmer, who said he has “never once used the word ‘cure’ in my work. I have never claimed to have cured any mental illness, including schizophrenia,” but added: “I have talked about ketogenic diet being a very powerful treatment, even to the point of inducing remission of symptoms of schizophrenia.”

Of all the things to criticise RFK for, confusing the technical definition of “cure” and “treatment” seems like pedantry.
