The hairpin trigger level effect, where there is barely enough of an allergen or poison NOT to cause a reaction would not end with soy. Other poisons or allergens could be included also.
These "trigger levels" would not all be stable forever. If the body system becomes depleted, or sick or other factors change, then symptoms would start appearing (or go away) until the body heals or fixes or changes itself back to "normal".
Again: The trigger levels would not necessarily be stable or remain the same.
Also, varying amounts of different poisons or allergens would affect other trigger levels........
What could affect or change these trigger levels in the human body?
diet, emotions, stress, vitamins, age, iodine, fasting, weather etc.
