I used to get a cold every few weeks and it would be terrible to try to recover from it. It usually turned into some sort of respiratory infection. I didn't make the connection then, but I was eating a lot of chicken soup during times of illness. I was mainly buying Cambell's chicken and noodle or chicken and rice or occasionally Progresso or some other brand. So I was pumping myself full of allergens. I have a severe egg allergy and also a dairy allergy. Oddly the chicken and rice soup contains milk! So it's no wonder I was getting sick all the time and not getting better.
Seems like it took about 2 whole years to get better from the time I eliminated the allergens. I didn't learn of the food allergies until age 46. Daughter has been much better too, having missed far less school this year than in past years. She does have more allergies than I do and more chance of getting cross contamination.
At any rate, it is soooo nice to feel so much better!
