I have found that if I eat anything with corn in it I will get a sinus infection I have alway thought it was the high frutose corn syrup because if I eat or drink anything with the corn syrup in it I get sinus infections. Also just corn tortillas will do it. I don't know if it is just all the altering of the corn to to enhance the growing process but something is wrong with corn now. Also, when something tends to be in everything...just the amounts that are consumed can create allergies to it. All I know is that Corn is one of my biggest factors in getting sinus infections and bronchitis. If it does go into my chest... Lymphomyosot by Heel is a good homeopatic remedy for it. I can alway clear up the bronchitis within 24 hours with it. Just take it every 20 minutes until you feel it getting better then do it 2 to 3 time day until well. I don't get bronchitis anymore since using it. I use to get bronchitis 2 to 3 times a year before.
