Blood type diet

[Guest guest]

I recall some time ago Mel Siff taking the blood type diet promoted by

D'Adamo to task for a lack of evidence. This interesting study just

appeared. It correlates blood type to diet but some of the

recommendations are different than the original " blood type diet "

suggested (e.g. beans are recommended for type A in the D'Adamo

system).

Abstract

Purpose: The goal of this research was to determine patterns in

adverse food reactions among human biotypes, if any.

Design: Blood types A1, A2, B, AB, O and Rh-negative were correlated

to four kinds of food allergies and hypersensitivities.

Materials and Methods: Three studies were conducted from 1985 to 2004.

Blood types were correlated to food scores from: (1) mRAST-IgE food

allergy tests, (2) mRAST-IgG food hypersensitivity tests, and (3)

T-cell food hypersensitivity tests (ELISA/ACT® LRA). An allergy

history was recorded. Data were evaluated by statistical analyses,

including: ANOVA, MANOVA, Mann-Whitney U, Kruskal-Wallis, and Chi

Square. Clinical categories were established by means and ranges. (4)

Blood-type specific lectins were included from the scientific

literature.

Results: Results were reported by blood types and food groups as raw

scores and classes, and included the following: blood type A1 reacted

most strongly to nuts and beans, eggs, dairy, and nightshades; while

type A2 reacted to the same but more strongly to dairy, eggs and

gluten grains. Type B reacted most to eggs, nuts and beans, dairy,

gluten grains, nightshades, and sugars. Type O reacted most to dairy,

eggs, gluten grains, and nightshades. Type AB reacted most to nuts and

beans, seafood, eggs, and dairy; while A2B also reacted to gluten

grains. Type Rh-negative was most reactive to eggs, dairy, nuts and

beans, and gluten grains. The highest IgE scores were among types B

and Rh-negative. The highest IgG scores were among types O, A2 and

Rh-negative. The most lectins reacted with type AB.

Conclusions: The research showed patterns in food group allergies and

hypersensitivities based on ABO, A1/A2 and Rh blood types. Biotype

Diets is the first diet-typing system supported by original scientific

research, and has greater accuracy and specificity than other systems.
