A study carried conducted in Germany in 1981 involving 13,000 patients concluded that there was a significant risk of heart disease, primarily in type ‘A’ blood groups.
Blood samples taken; revealed a stronger concentration of erythrocytic antigens in type ‘A’ blood types. The’ British Medical Journal’ carried out a study spanning over 8 years involving approximately 7,000 males and ‘serum cholesterol’ levels taken from type ‘A’ blood samples showed to be higher than other blood types. In a second study – blood samples from approximately 3,000 patients were tested involving 2 age groups, – i.e. 65 years of age and over, and age 65 years and younger. Results showed that blood type ‘A’ participants had a higher association with cardiac infarction and this applied to both age groups. The study concluded that a genetic factor is associated with blood group ‘A’ in relation to the incidence of cardiac infarction. In subsequent clinical research studies – Type A blood groups appear to possess a naturally high level of the stress hormone ‘cortisol’ which result in a higher concentrations in response to stress.
Higher cortisol levels can result in various stress responses and lead to disrupted sleep, increased blood viscosity (blood thickening), and insulin resistance. A naturopathic physician known as Dr. Peter J D’Adamo, and famous for his – ‘Blood Type Diet’ publications, recommends that people are best suited to a eat according to their blood group. His theory is based on ancestry. For instance when – blood type ‘A’ individuals evolved around 15,000 B.C. their diet mainly consisted of vegetable matter and this is what they became adapted to. Dr. Peter J D’Adamo believes that such biological adaptations still exist in the digestive system of blood type ‘A’s’ bodily functions today, and therefore suggests diet plays an important role in how different blood type individuals digest and process the type of food they eat.
One of Dr. Peter J D’Adamo’s theories is that type A’s possess lower levels of hydrochloric acid in the stomach, which result in proficient digestion of carbohydrates, but low levels of ‘intestinal alkaline phosphates’ also prevent digesting and metabolizing animal protein and fat as easily.
Should I be worried if I am blood type ‘A’?
Every individual is faced with potential health risks according to many factors including diet, lifestyle, environmental, and genetic predisposition etc. Everyone – not just type ‘A’ should adhere to suggested recommendations set out by ‘The British Heart Foundation for optimal heart health such as: refraining from smoking, exercising regularly, drinking alcohol in moderation, maintaining a healthy weight and BMI, (body mass index) and monitoring your cholesterol levels. (Some pharmacies now offer this test).
Try and prevent elevated cortisol levels, by avoiding unnecessary stressful situations. A switch to a healthier lifestyle will help to cut down your risk considerably. It may be well worth looking into the prospect of the possible benefits of diet and blood type by researching publicised testimonials and scientific studies.
