Introduced in the year 1996 by Dr. Peter J. D’Adamo, the concept of eating right for your blood type has become the sought after diet regimen in the recent times, particularly with many notable celebrities like Liz Hurley and Courtney Cox Arquette. According to him, blood type seems to provide the most reliable perspective about an individual’s overall health. Dr. D’Adamo’s eating right for your blood type concept is primarily based on the observation that by means of right food and right exercise, which aptly suits your blood type, it is possible to rejuvenate the natural genetic rhythm of the body. In this manner, you can lose weight easily, feel healthier, and can considerably reduce the risk of illness.
Origin of Blood type Diet – Origin of eating right for your blood type theory stems from the observations made by Dr. Peter J. D’Adamo and his father regarding the evolution of blood types and the dietary habits followed by our ancestors during that period. According to them, Type O is the most ancient blood types thought have existed during the pre-historic period, when humans were mostly hunters and relied only on meat. Blood type A originated when humans adapted to agriculture as means of living and started dwelling in communities. During this period, our ancestors typically followed a vegetarian diet. To facilitate the adaptation of humans to variable climatic conditions, Type B came into existence. People with Type B blood followed a balanced diet regimen that included vegetarian, non-vegetarian, diary and poultry foods in equal proportions. Blood type AB is believed to be the most recent blood types thought to have originated some 1000 years ago due to mixture of A and B blood types.
Definition of Blood Type Diet- In humans, blood groups were first discovered in 1901 by Dr. Karl Landsteiner and were categorized into A, B, AB and O. According to conventional belief, all the four blood groups are not compatible with each other due to presence of antigens on the surface of RBC. When unrelated blood groups are mixed, it results in the formation of antibodies against non-self antigens resulting in the blood cells to clump together, a process termed as agglutination. However, in his eating right for your blood type theory, Dr. D’Adamo predicts that blood cells undergo agglutination even due to a certain group of glycoproteins present in the foods called lectins. According to Dr. D’Adamo, specific lectins are compatible with specific blood types. Moreover, individuals with certain blood types such as Type O and Type B can tolerate lectins better than other blood types. When foods containing lectins are consumed, these proteins are absorbed into the blood through the intestinal lining. In the blood, lectins get attached to the red blood cells causing them to agglutinate, thereby resulting in conditions such as GERD, bloating, stomach pain, liver cirrhosis, and kidney failure.
How Long You Have To Be On This Diet – Dr. D’Adamo suggests remaining on a blood type diet regimen for at least 2 weeks to gain noticeable benefits. For long term benefits, it is important continue the diet pattern as long as you live. Under eating right for your blood type theory, all the foods have been categorized under 16 food groups such as meat, sea foods, eggs and dairy, cereals, fruits, vegetables, oils and fats, spices, condiments, and beverages. For each of the blood type, foods in these food groups are again classified under three different types that include foods that are highly beneficial, foods that do not cause any harm and foods that must be strictly avoided. The basic idea behind eating right for your blood type is primarily to consume foods that are categorized under highly beneficial and neutral list and stay away from those listed in the foods to avoid list. For example, while foods such as chicken, mutton, beef, eggs, cheese, and dairy products are highly beneficial for Type O individuals, the same foods must be consumed in limited quantities by persons with Type A blood type. On the contrary, Type AB individuals should completely refrain from consuming any high-protein diet in the form of meat or dairy products. In terms of physical exercise, mental relaxation activities such as yoga, meditation, and breathing exercises are suggested for Type A persons. On the other hand, Type O individuals should follow a rigorous or intense physical exercise regimen that can include activities such as swimming, jogging, cycling, or aerobics.
According to some experts, there is no substantial evidence to support Dr. D’Adamo’s diet-related suggestions. Some even suggest that eating right for your blood type might even result in depleted nutritional intake in people, thereby leading several nutritional disorders such as osteoporosis. Right now, it is up to individual discretion to whether or not to follow a blood type diet. It is recommended to see your doctor and nutritionist to find out what they have to say about each individual case. Nevertheless there are many satisfied users who not only enjoy the healthy life style but also loose weight.
