People find that they have intolerances to foods such as wheat, other grains, fruits, dairy products and a variety of other foods. If a person suffers headaches caused by foods it is important to go through a process of elimination (I think it is elimination or discharging when I throw up all the food in my stomach). Food allergists can assist a person in eliminating probable food causes one by one from the diet until the guilty foods are found.
I think the above sentence fit for me, maybe I have intolerances to some food. Tsk, here I am again self medication. I think much better if I took a nursing course because I am expert in self medication. Haha, joke. Or maybe I have diabetes because it also says that getting headaches after eating can be an early sign that diabetes may be a problem.
