I agree with this too, and to expand a little bit, the problem with wheat is not the wheat itself, but gluten. Gluten is a problem for the MAJORITY of people. There are so many possible reactions to Gluten that most people will never imagine that Gluten is causing some rare lifelong effect or disease. There are cases in which people with rare skin disorders and even lung issues like COPD have been immediately cured when stopping gluten. Not all of cases of course, but some people are that sensitive to gluten. Gluten can cause a wide spectrum of variety disorders and chronic diseases including asthma, rosacea, psoriasis reproductive issues, gastric problems, allergy problems, etc. Again, not all these diseases are caused by gluten but a lot of people who stop gluten can see a complete cure of the disease.
One of the first things to do when reorganizing a diet is to stop gluten. Specifically Wheat, Barley, Rye and Oats. Avoid Oats even if it says gluten free.
