Food has so many properties that we often draw false conclusions, when we only focus on one aspect: e.g. you can easily be misled into thinking bananas and whole grain products are "unhealthy" when you only look at it from its impact on blood sugar coming from a keto diet point of view. Or you can be misled into thinking that plants should be avoided because they contain small amounts of toxins, and therefore you should follow a carnivore diet (meat-based).

The fact is, however, that it is about quantity.

Anything can be toxic if the dosage is high enough.

And just as exercise and resistance train our muscles - but must not be overdone, because then it breaks us down, likewise fibers and many of these antinutrients actually train our digestion, so that it becomes resilient and results in a diverse and healthy gut microbiome.

Now if you are already sick you may of course need a targeted elimination diet temporarily in relation to symptom management short-term - but this will never cure the underlying problem. Eg. mold is linked to IBS, which in turn is linked to SIBO/SIFO, so if you focus on the intermediate or end product, you never get to the bottom of what is causing the inflammation in the intestinal system and the overgrowth of bacteria and fungi in the small intestine and the resulting " food intolerances".

Bottom-line: if you struggle with a lot of food intolerances and digestive issues a restrictive diet will not cure it, but may manage the symptoms short-term, yet longterm may make the problem even worse.

Restrictive diets are NOT healthy longterm. And if a practitioner is recommending such, it is a RED FLAG.
