I kind of wondered about that. I recently went backpacking in the Winds. I was hardly troubled by mosquitoes at all. They did bother me some. I really hate it when they bite through my shirt on the backs of my arms and shoulders, and they did that a lot. But oddly I maybe scratched the bite once and by the next day the bite was gone. Other times I could be standing there with my friends and mosquitoes are all over them and not so much on me. I always wondered how other people could tolerate mosquitoes with such a calm attitude and here I was tolerating them calmly. If that's from eating less grain starch and sugar, then yay! What a wonderful benefit.
