The food intolerance test has been updated. A few people were showing a very mild intolerance to kola nut, but with so little information available on what foods this is added to and why, no real action could be taken to avoid further symptoms.

Cola nut has now been replaced by tea, which is very common in the British diet and should an intolerance to tea occur, definite action can be taken.

If you do have a kola nut intolerance, it is likely to be very mild. However, avoiding it is very difficult. The most information that I've been able to glean is "Kola nuts and kola extract are used in the manufacture of soft drinks, alcoholic beverages, candy and nutritional supplements" (ref).
