The premise of D’Adamo’s work is that your blood type determines what you should eat.
TYPE O Blood: Approximately 45% of the human population is Type O, the oldest type on the planet. People with Type O blood should eat a low-carbohydrate, high-protein diet because their digestive systems have the necessary stomach acids to process heavy foods, and because meat is essential to keep their sugar levels in balance. Their main beverage should be water. They should eat meat, fish, fowl, leaves, roots, berries, seeds, and nuts, but avoid dairy and most grains, especially wheat. Since these foods developed late in the evolutionary cycle, Type Os are not adapted to consume them. They are “cavemen” eaters whose main diet should consist of meat and fresh vegetables.
TYPE A BLOOD: This type accounts for 40% of the population. The second oldest blood type, Type A appeared when humans became farmers. Type As are best adapted to eat a vegetarian diet consisting of fish, legumes, lentils, tofu, fermented soy products, nuts, seeds, grains, fruit, and vegetables. They should avoid dairy products and consume only small amounts of chicken and turkey. Whole grains are acceptable, but they should avoid refined flours and sugary foods like cakes and cookies. Their beverage is green tea.
TYPE B BLOOD: People with Type B blood date to a migratory period in human history, and are adapted to cold climates. Making up only 10% of the population, they are the only group that can consume dairy products. They can eat “cold climate” meats such as lamb, mutton, rabbit, venison, and fish, as well as all other meats and fish. They should avoid grains and other carbohydrates, but concentrate on fruits and milk products. Their beverage is also green tea.
TYPE AB BLOOD: This group, represents only 4% of the human population, came about as a result of intermingling Types A and B. It is the newest group and has some characteristics of both A and B. Their proteins should be fish and soy products, and they can consume lamb, turkey, and rabbit but not chicken, duck, or guinea fowl. Like Type A, they can eat cereals, breads, pasta, and grain-based foods. As for dairy, Type AB can eat cheeses made from cow, sheep, or goat milk but they usually benefit from avoiding most other dairy products. They can eat nuts and seeds and their oils, plus all vegetables.
The Blood Type Diet books are full of anecdotes from people who claim this new way of eating cleared up health problems such as allergies, migraines, diabetes, backaches, high cholesterol levels, fatigue, overweight, and more.
