parasites love glucose yes, however depriving them of it will force them to look for it (esp if they in your head area) and it can be dangerous since they will go for your brain since it has the majority of the glucose. Second if you limit the amount of glucose in your diet be ready to give the majority of it to parasites. Diet might help with inflammation from parasites but that's it.
And make sure you wash your raw organic food. Because it can be actually full of parasites.
