As we all know, human blood is grouped into four types: A, B, AB, and O with each letter referring to a type of antigen, or protein, on the surface of red blood cells. The percentages of people who have these blood groups in the United States is:
Or – 45%
A – 40%
B – 11%
AB – 4%
These percentages may vary in certain sections of the country depending on the cultural makeup of the population. Several studies are underway showing that blood group and longevity have been linked. Research has shown that blood group O has the longest lifespan.
A’s live approximately 61.6 years
AB’s …………………………… 69.5
B’s ……………………………… 78.2
O’s ……………………………… 86.7
People with blood group O have been shown to have a good ability to ingest meat proteins, have a strong immune system, and a robust digestive tract. They respond better to stress with vigorous physical activity. They are less prone to heart disease as they have more fluid blood, less likely to clot, but may be more prone to ulcers, blood clotting disorders, arthritis, hypothyroidism, and allergies. However, those who changed their dietary lifestyles, such as eating less potatoes and dairy, were less prone to arthritis and related ailments. O’s ailments are more painful but less deadly.
Blood group A does well on a vegetarian diet. They do not properly metabolize meat and dairy products loaded with saturated fat. They can be more prone to heart disease, diabetes, cancer, liver and gallbladder disorders, and have a vulnerable immune system. It is interesting to note that Japan, a country that consisted predominantly of Type A, has the longest lifespan record of any country in the world. (78 years for men and 86 years for women) The reason is that they eat according to their blood type. Their staple diet is fish, rice, soy products, and green tea. This diet consistently promotes good health and provides the greatest potential to prevent heart disease.
Blood group B accepts both meat and dairy products well. They live the second longest. They have a tolerant digestive tract, a strong immune system, a flexible adaptation to a new diet and environment. However, the improper metabolism of some specific foods makes them susceptible to autoimmune disorders.
Blood group AB has mixed characteristics of blood groups A and B. They may have a sensitive digestive system but an overly tolerant immune system. Research shows that the shelf life is longer than A but not as long as B.
Proper diet has been found to extend the lifespan of each blood type. As Ben Franklin has said, “An ounce of prevention is better than a pound of cure,” any food containing saturated fat is known to have the greatest potential for long-term damage to the body, regardless of blood type. There is a popular belief in Japan that a person’s ABO type predicts their personality, temperament, and compatibility with others. In Japan, the idea of blood type as a personality type is so popular that the Japanese ask, “What is your blood type?” instead of asking “What’s your astrological / zodiac sign?” In short, Type A is believed to be calm and reliable; Type B is creative and excitable; Type AB is reflective and emotional; and Type O is a confident leader.
Scientific inventions unravel riddles and scare even the most awake and enlightened. This area of blood group and its links to longevity requires more research for our entire society to benefit from living more productive, healthier, and longer lives.
