Even the tiniest amount can cause a severe reaction. Consult your allergist regarding an epinephrine autoinjector. ...Read more

What kind of specialist should I get for soy, peanut & histamine diet so I won't get an allergic reaction and lose weight.

A dietitian, not a: physician, most likely. Histamine= a hormone made internally (not in food) & induces itching & capillary dilatation/redness; i.e. allergic response.

I hear so much abt allergic reactions that i've started avoiding peanuts, fish, etc, even tho I have no food allergies. Overreacting?

Yes: The guidelines that are published for evaluation and treatment of food allergies do not recommend testing without a prior reaction/symptoms after eating. If you have never had any problems with a specific food, avoiding them proactively would be unneccessary. I do admire your desire to be proactive though. ...Read more
