Due to the fact that it can be hidden and is unrecognized as a food allergy, it is extremely difficult to avoid in the USA and most people do not even understand why they are getting sick. They are told by the medical industry they have IBS or acid reflux, etc.

Annatto will affect most every system of the body. Since I have attempted to avoid it I have noticed improvements in my gastrointestinal, urinary tract, skin, headaches, dizziness, and even sinuses. I was suffering from exposure for over 40 years and on medication for 10 years before someone alerted me to this issue. I have not needed any medication [except on accidental exposure] since I have chosen to avoid it over a year ago - Sylvia, USA.
