The blood group diet is said to have originated from two American Naturopaths, Dr James D’Adamo, and his son Dr Peter D’Adamo, who believe that your blood group type is the key to how you burn your calories, which foods you should eat and how you would benefit from certain types of exercise.
They recommend that eating to suit your blood group may, help you to lose weight, help you fight disease, boost your immune system and slow down the ageing process.
It is believed that a chemical reaction occurs between your blood and foods as they are digested.
There are 4 blood types: O, A, B, and AB. “Eat Right 4 Your Type”
- BLOOD TYPE O
The O blood type was the first blood type to evolve from the hunter-gatherer era around 50,000 BC. Here the diet was high in red meat and virtually void of grains and dairy. The type-O thrives on a meat-eating diet. As the diet is high in animal protein, the type-O requires intense physical exercise to help burn off the meat.
People with Blood Type O should basically stick to a high protein diet (including red meat), low carbs, and enriched with fruits and vegetables.
They should limit the intake of wheat germ, whole wheat products, corn, and avoid dairy products and most nuts. Wheat and dairy also promote inflammation in this blood type which can trigger an imbalance in the immune system.
Type-Os are prone to digestive disorders resulting from over-secretion of stomach acid (leading to ulcers). They can also be more susceptible to arthritis and thyroid disease due to overactive or hyper -immune system.
Blood type O individuals can gain a significant amount of weight following a high carbohydrate diet, as their bodies cannot properly metabolize these foods.
- BLOOD TYPE A
Type-A blood group formed when man began to develop an agricultural lifestyle between 25,000 and 15,000 B.C.People with blood type-A do best on a vegetarian diet for weight loss especially the macrobiotic diet. They should basically stick to fruits and vegetables (high carbs / low fat).
The type-A individual hardly produces much hydrochloric acid and therefore does poorly on meat and dairy diets such as the Atkins Diet.
Type-As are generally more prone to cancer, diabetes and heart disease, if they do not take charge of their health. The gene for alcoholism is also found in type-As. They have thicker blood than other blood types and a sensitive immune system.
- BLOOD TYPE B
Type B also evolved from the intermingling of blood type O with the blood type A. This occurred between 15,000 and 10,000 B.C due to man traveling further.
As a result, the type-B individual does best on a balanced diet (fruits and vegetables, grains, fish, dairy, meat,( but avoid chicken).
The type-Bs suffer from the highest incidence of bladder and urinary tract infections. They are also prone to viral diseases when their immune system is compromised, yet they have the best chance of bypassing or overcoming everyday types of diseases, including heart disease and cancer.
Since B blood types can metabolize dairy products and most foods, they will usually lose weight effortlessly as long as peanuts, corn, wheat, and lentils are eliminated from the diet.
- BLOOD TYPE AB
The rarest and newest blood type to evolve (1500 years old) was the AB blood type. This blood type is the best adapted to a moderate diet. The type-AB individual benefits from both the A and B type diets.
They should consume a mostly vegetarian diet. Meat is not as well digested as seafood, dairy, wheat-free grains and soy foods.
The type-ABs is prone to either diseases encountered by the Type-As or the type-Bs. By undergoing further metabolic typing, it can be determined which diseases they are most likely to be vulnerable.
For weight loss and maintaining a healthy weight, AB’s do best on seafood, dairy, nuts and grains.
Blood Types don’t change, so recommended Diets according to the “Eat right 4 your Type / Blood Type Diet” concept remain fixed and don’t change either, however many medical conditions change over a lifetime, and as a result require a change in medications and Diet.
