A number of these treatments have peculiar side effects and placebo effects that can sometimes cause accidental improvements in people's symptoms. They do not in and of themselves effect a cure, nor do they point towards an alleged cause of food chemical intolerance.

It is possible to have some of the listed diseases (i.e. candida, dysbiosis) but they are caused by food chemical intolerance rather than being causes of food chemical intolerance.

It is possible to be intolerant of foods avoided on some of the above diets, but these foods are not the cause of food chemical intolerance, merely a part of food chemcial intolerance.
