Biotype Rh-negative is a Basque biotype. This type has inherited a Basque gene for blood type Rh-negative from ancient ancestors in the Pyrenees Mountains of France and Spain. Their ancestors adapted to their specific ecosystem over long periods of time in isolation, and modern Rh-negatives have inherited those adaptations. They fare best with a temperate hunter-gatherer diet of Western European foods, such as meats, poultry, seafood, roots, tubers, and European fruits and vegetables, nuts and seeds.

The Biotype Research shows that blood type Rh-negative has more IgE allergies than Rh-positive. In fact, Rh-neg has the highest rate of immediate allergies of all blood types. The graph at right is an example. This biotype especially reacts to nuts and beans, but also to eggs, some meats, gluten grains and nightshades, as shown below. Their worst allergen is peanuts, a native American food. IgE Scores of 500-750 are mild, 750-1000 are moderate, and 1000-1250 denote strong allergies. Blood type Rh-negative also displays delayed allergies, including: strong IgG allergens, and some T-cell allergens. (Not shown.) For more on this type, see the Biotype Diets book.
