Why is a certain item green if I have an intolerance to it?

Understanding the Results

Reason 1: It may take an intolerance of 3 to 5 days, or even weeks, months, or years, to manifest symptoms. It is still possible that the suspected intolerance is not the real one since an individual can ingest up to 100 different foods in a single day, including herbs and other compounds. 

Reason 2: Intolerances can be treated, unlike allergies. To boost your health, you can decide to stay away from something that tested as red or orange for a while. You might take another intolerance test a few months later and find that item is green on your results. This may imply that the intolerance was successfully treated by your body.
