My throat swells when I drink the Lactaid milk and when I chew the Lactaid tablets. I tried the Dairy-Ease milk but same problem. I found out that the commercial lactase is made using yeast and/or mold. Xantham gum is made from mold or cultured on corn as a mold. my stomach swells when I eat anything with xantham. Does this mean I have a yeast intolerance...
