- 1.1 The Rh antigens either present in our blood or not. If you have the Rhesus factor, then you positive are (Rh + individual Rhesus), and if you have not you are Rhesus negative (Rh-).
For the past several years, several epidemiological studies have demonstrated statistically significant correlation between blood group and incidence of certain diseases.
Unfortunately some of these were used as a means of identification of racial purity and so were scientifically unreliable. Others studies did not receive the required international attention, because were in Japanese and South Koreans, nations where the issue of blood groups is an integral part of their national culture.
In Japan, say, almost the entire population using blood groups as a “tool” for all kinds of forecasts, analyzes, decisions and actions. The huge commercial success last but years various diet books based on blood group and particularly developments in genetics to the analysis of the human genome were triggered both reviewing previous work and to conduct specialized GWAS studies (association study method widely genome), which are further enriched our knowledge of the relationship between diseases and blood group.
What is the blood?
Groups or blood types are the categories that distinguish the blood depending on the presence or absence of certain substances present on the membrane surface surrounding the red blood cells. Chemically specific substances belonging to the proteins, called antigens. The antigens of red blood cells is too many, but the most important clinically are those belonging to two antigenic systems, the ABO system and RHESUS system, from which the blood groups have taken their name in man.
If you have the A antigen, you belong to the blood group A.
If you have the B antigen, you belong to the blood group B.
If you have the A antigen and B antigen, you belong to the blood group AB.
If you have neither antigen A nor B antigen, you belong to the blood group O.
The Rh antigens either present in our blood or not. If you have the Rhesus factor, then you positive are (Rh + individual Rhesus), and if you have not you are Rhesus negative (Rh-).
The blood groups are inherited, ie genetically determined and accompany us throughout our lives. Their incidence in Greek population is about: blood group A 44.4%, group A 37.9%, group B 12.9%, group AB: 4.7%. Estimated Rh + is approximately 85% of the population, while 15% Rh-.
Magazines publish forecasts based on blood group, something akin to our own horoscopes.
Not to ask what sign you are, but what blood type you have.
The blood group considered an element that indicates what personality you are and for that reason a criterion for recruitment executives, conclude friendly or social relationships, sexual partner selection and wife!
Politicians, artists, athletes and generally popular person ever mentioned in their CV their blood group.
The sections of kindergarten and school workshops are structured with a defined hematologic typology.
It is advantageous to have blood type O, because the majority of the Japanese Group A.
What do recent research?
New discoveries and documented evidence on the relationship of blood groups and disease
Heart disease: The higher risk for heart disease event at individuals with blood group AB, while the smaller people with group C. More particularly, the risk is increased by an average of 23% in individuals with blood group AB, 11% in those with group B and 5% of people with group a compared with individuals of blood group O.
Myocardial infarction: People with blood type O are more protected from heart attacks and thromboembolism even have experienced coronary disease. Conversely, the genes of blood groups A and B do not offer such protection and associated with myocardial infarction without binding to coronary atherosclerosis.
Skin Cancers: Compared with other blood groups, people with type O are 14% more likely to develop skin basal cell carcinoma (BCC) and 4% more likely to anthokyttariko carcinoma (SCC). Melanoma, the most dangerous form of skin cancer, it does not seem to be related to blood groups.
Pancreatic cancer: People with blood group O is relatively protected from the disease and may have a much lower risk of developing pancreatic cancer, while subjects with group B have the highest risk. Compared with blood type O, people with group A are up to 32% more likely to develop pancreatic cancer, people with AB group 51% more likely and those with group B 72% more.
Ovarian Cancer: The presence of the antigen B (blood group B and AB) is positively associated with the development of epithelial ovarian cancer, and the blood group A showed similar correlation.
Prostate Cancer: The incidence of prostate cancer and its outcome varies depending on the blood group. Men with blood type O with advanced prostate cancer who have undergone radical prostatectomy may be more protected from the recurrence of this cancer compared to those with group A.
Gastrointestinal: Stomach cancer is more common in people with blood group A. People with type O are more vulnerable to infection by Helicobacter pylori and are more likely to develop stomach or duodenal ulcer.
Obesity: Men with blood group O significantly higher risk of obesity when working in areas with strong pollution.
Nutrition and blood groups: There is no scientific evidence to suggest that the nutritional standards based on blood group, as described in the books of Peter D ‘Adamo «Eat Right for Your Type» and «Live Right 4 Your Type», have positive effect on health indicators and / or reduce the risk of chronic diseases such as cardiovascular diseases.
Researches in the Greek population show statistical correlation of blood groups with stomach cancer, duodenal ulcer and incidence of secretory otitis media in children.
From what “danger” of what “protected”
Careful review and analysis of published research shows that blood group you belong to may predispose more for the onset of certain diseases Or, conversely, to provide greater protection against some others.
Blood Group O
Increased gene protect against heart disease
Possible biases: Do you have an average higher BMI and higher body fat, men show susceptibility to chronic inflammation that can lead to obesity. You are more vulnerable / s in respiratory allergies, flu, strep, stomach and duodenal ulcer, severe gastroenteritis and other gastrointestinal problems caused by viruses and bacteria. Manifest most often attacks of asthma, arthritis, autoimmune thyroid diseases and certain types of skin cancer. Show a higher rate of insulin resistance, metabolic syndrome, fungal infections, dental problems, Parkinson’s disease and inflammatory bowel diseases.
Optional protection: You have somewhat greater genetic protection from heart disease and heart attacks, have more favorable cholesterol levels in the blood, better blood circulation and lower thrombosis rates. Show more rare pancreatic cancer and fewer fractures due to osteoporosis.
blood group A
Susceptibility to abuse
Possible dispositions: demonstrate higher cortisol levels, increased insulin resistance and predisposition to abdominal obesity type. The levels of “bad» LDL cholesterol is usually high, you run a greater risk for heart disease. Your blood clot more easily. Shows frequently of stomach cancer, and there is evidence for most elevated expressions of colorectal cancer incidence, esophagus and breast. You susceptibility to digestive problems, anemia, hypothyroidism, osteoporosis and chronic degenerative diseases. You are more vulnerable / s anxiety. Often katafef- GATS tobacco, alcohol, drugs or other addictive substances.
Possible protection: have low incidence of cancer of the bladder, urinary tract infections less often, higher resistance to viruses. Women may keep for more years to your reproductive capacity.
Blood type B
Possible dispositions: Have lower levels of Nitric Oxide (circulatory problems, difficult blood flow, increased chances of erectile dysfunction in men), high cortisol production and a high proportion of abdominal fat. Higher risk for pancreatic cancer and ovarian cancer. Suffer more frequently from depression, autoimmune diseases, sinusitis, hypertension or hypotension, urinary tract infections and infections. You are more vulnerable / in the chronic fatigue syndrome, and pathogenic organisms derived from food. At older ages experiencing frequent memory loss.
Possible protection: Rarely digestive problems. Are at lower risk for arthritis manifestation, streptococcus and influenza B. If you sensitive are and / s to stress, the physical impact on your health is probably limited.
Blood type AB
A higher risk of heart disease
Possible predispositions: Are you more prone to heart disease due to vascular inflammation, hypertension, high cholesterol, excessive blood clotting and oxidative stress. Presented Jerk often nervous, digestive stress, food hypersensitivity syndromes and high intestinal toxicity. Have more likely to manifest bipolar depression, gastrenteri- Kush cancers, ovarian cancer and pancreatic cancer, kidney disease, gallstones, osteoporosis and Parkinson’s. Cardiac and cancer patients usually have a worse prognosis. Pregnant women have a higher risk of developing hypertension and preeclampsia.
Possible protection: Your immune system is generally more powerful and durable, are less prone to viruses and infections, recovering faster than them. Although often experience excessive stress can be managed successfully.
There are no “best” and “worst” blood groups and no blood is not sufficient by itself to cause health problems or, conversely, to create immunity – a disease may manifest or not regardless of blood group to which we belong and risk probabilities theoretically have.
Priority to prevention
Despite increased research evidence, the findings so far do not show a direct causal relationship between blood groups and disease, or disclose specific biological mechanisms that increase or decrease risk, therefore can not be used as a predictor of the disease index. Until then subsequent inquiries to confirm any compelling correlations, the best way of protecting our health is a healthy lifestyle. Not smoking, avoiding obesity, Mediterranean-type diet and regular physical activity are preventive measures beneficial to all blood groups and unambiguously can favorably modify an unfavorable genetic predisposition, to postpone the event and even to the silence ..
