The Biotype Diets™ Research
How was the Biotype Diets™ Research performed? I used a branch of research called epidemiology. This relates different variables to each other using computerized statistics to determine the relationships between them. I used this method to conduct three original research studies. I gathered blood types and food allergy scores on 500 subjects. Then I statistically correlated them. Specifically: I matched 6 blood types (A1, A2, B, O, A1B, A2B) to all four kinds of allergies – for each food tested. I also evaluated for subtypes: Rh-negative, gender and age. I employed three kinds of allergy tests: Type 1 allergies (IgE antibodies), Type 3 allergies (IgG antibodies), and Type 4 allergies (T-cells).

In addition I researched lectins in the scientific literature (both blood-type specific lectins and panhemagglutinins). To make a Food Allergy Index and a Food Allergy Pyramid I integrated all four allergy results (raw scores) using an algorithm based on percentages, which allowed me to rank the foods for allergic reactivity. I then assigned an "allergic class" to each food for safe, allergic or borderline status based on standard deviations.

Laboratories
I was fortunate to have two excellent allergy specialty labs to work with: Commonwealth Medical Labs (IgE and IgG) and Elisa/Act Biotechnologies (T-Cell). Both labs employ the highest standards, have federal certification (CLIA), and have proven to provide reliable results over the years.

Scientific Advisors
When I first began many years ago, I used the preliminary results of my two small pilot studies (IgE and IgG antibodies) for my thesis in Nutritional Sciences at the University of Maryland. I was fortunate to have wonderful advisors: Dr. Robert Jackson (nutritional epidemiologist), Dr. Estelle Russek-Cohen (biostatistitian), Dr. Fatimah Jackson (nutritional anthropologist), and Dr. Dean Metcalfe (the head food allergist at the National Institutes of Health as an advisor to my committee). They taught me how to do epidemiological research. I continued to enlarge the studies for another decade and more, getting better and different results. I added the T-Cell study and known lectin patterns. I then integrated all four allergy studies together to form the Biotype Diets.

Resources
I also spent much time in the National Library of Medicine researching lectins and blood types, and in the National Agricultural Library researching the geographic origins of foods. Online scientific sources were utilized as well, Medline, etc.

The Biotype Diets™ System
After 20 years this finally led to the formulation of the Biotype Diets. This incorporates all 4 allergy studies. It provides six optimal diets based on blood types: O, A1, A2, B, A1B, and A2B. In addition, there are sub-type modifications for blood type Rh-negative, gender and age.

Publications & Rights
I hold copyrights on the early pilot studies. In July 2004 I filed a patent application for the Biotype Research, and in January 2005 a trademark application for Biotype Diets®. In late 2004 I licensed my patent to David Vaughan for use in his Food Pharmacy® Diet Therapy® software for professionals. I am writing research articles for peer reviewed publications. I am also writing a book for the public. I am happy that I am at last able to share these wonderful results with the many people who need them.
