Dear E.,
Our children have allergies and I had severe allergies when I was younger. I tried everything and the only thing that worked is Nutritional Yeast Flakes, manufactured by Kal. Or you can purchase yeast flakes from www.bulkfoods.com The nutritional yeast flakes are actually one celled plants, so they come under the heading of food. This is not baking yeast.
The theory is that allergies start in the gut, with improper digestion. This causes a fungus to grow which is candida. This can get so bad that the candida can become systemic. The only thing that worked was a sugar free diet for four months and gradually increasing the brewers yeast intake from 1/2 teaspoon daily, to a teaspoon, then 1/2 a tablespoon, and so on, until up to several scoops of the stuff taken two or three times daily. For four months. This information is from a book titled Let's Get Well, by Adelle Davis and was written in the 60's or early '70's. She was a nutritionist that worked in John Hopkins Hospital and used her nutritional remedies on hundreds of patients. You can find this out of print book through Amazon.com
I did prescriptions, special diets, anit-fungals, meds. Nothing worked and I felt horrible. When I did the above outline and also stayed away from wheat, pasta, sugars, I was cured for life. Since then it has been 17 years, no allergies. I have also done this with my kids and they are allergy free.
It is your choice, but doctors do not have the answers, they give prescriptions that mask the problem but do not cure it.
I hope this helps.
D.
