A second generation naturopathic doctor, Dr. D'Adamo has been practising naturopatic medicine for over 20 years, best known for his research on human blood groups and nutrition. The Blood Type Diet came to light in 1996 with the release Peter D'Adamo's book "Eat right 4 your type". Acoording to Dr D'Adamo our blood group determines how our bodies deal with different nutrients; that each blood group has its own unique code and this code is not compatible with certain foods, leading to all sorts of potential health problems. Also, he believes that levels of stomach acidity and digestive enzymes are linked with your blood type.
Blood type O :
According to the theory, the blood type O was first identified in 50,000 B.C., and so type Os need to eat a typical hunter-gatherer type diet as their digestive tract retains the memory of ancient times. The blood type diet recommends, high protein, low-carb diet that are currently popular such as the Atkins diet. Food you can eat include meat, fish and olive oil. Moderate intake: nuts, seeds, eggs, certain food and vegetables. Avoid: dairy products, beans, cereals, bread, pasta, and rice. type of exercise: intense physical exercise such as aerobics, martial arts, contact sports, running.
* they are more likely to suffer from asthma, hay fever, and other allergies.
Blood type A
Blood type A evolved around 15,000 B.C. when our ancestors had settled into farming lifestyles, and eat lots of grains and vegetables but little meat. Those with blood type A, are more naturally suited to a vegetarian diet and foods that are fresh, pure and organic. What food to eat: nuts, seeds, beans, cereals, pasta, rice, fruits and vegetables. Avoid: meats and dairy products. Type of exercise: calming exercise such as yoga and tai chi.
Blood type B
Blood type B supposedly evolved around 10,000 B.C. thanks to our nomadic ancestors. They left their farms and started wandering the land, constantly moving from place to place. Food recommended: a varied diet that consist of most foods including meat, diary, grains, and vegetables. Avoid: processed foods, although nuts and seeds aren't recommended and only small amounts of carb-rich foods should be eaten. Types of exercise: moderate physical exercise requiring mental balance, such as hiking, cycling, tennis and swimming.
* they have a high allergies threshold, and will react if only they eat the wrong foods. And also, susceptible, to autoimmune disorders, such as chronic fatigue, lupus and multiple sclerosis.
Blood type AB
The blood type AB, the most recent, in terms of evolution just 1,ooo years ago! People with this blood type should eat the combination of the foods recommended for blood groups A and B, which is confusing as type B allows you to eat most foods, while type A suggest a vegetarian diet! Dr D'Adamo gets around this by suggesting that type AB's follows a veggie diet most of the time with some meats, fish and dairy products occasionally. Type of exercise: combine calming exercises with moderately intense activities.
* they tend to have fewest problems with allergies, while heart disease, cancer, and anaemia are medical risks for them.
* types A & B are the most susceptible to diabetes
* Types A & AB have an overall higher rate of cancer and poorer survival odds than the other types.
Thus, the author claims that his recommendations is based on scientific evidence.
