I was disgnosed with IBS and dust allergies due to my consistent migraines and indigestion about 2 years ago. I finally got fed up with the plethora of prescription drugs that filled my medicine cabinet and made an appointment with a local natropathic physician.
I was tested for Toxic Food Syndrome and found 18 different foods that my body reacted to! These included soy, brewer's yeast and many other healthy foods. After following the 4-day food rotation for about a year I now rarely get migraines, digest consistently, and have lost those last 5 pounds. What a relief! I recommend testing for TFS to everyone I know.
