China blood phenotype is dominated by O type, but the r gene frequency is obviously lower than other countries.
RH negative blood, compared with the common A, B and O types, is a variety highly unusual in China. With only 0.1% to 0.3% of the population having this blood running through their veins, it is therefore referred to as "panda blood." Rare as the blood type is, people with RH negative blood must not be ignored.
Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood. Types O negative and O positive are in high demand.
O-negative blood type is most common in the U.S. among Caucasian adults, at around eight percent of the Caucasian population, while only around one percent of the Asian population has O-negative blood type.
In Hong Kong, 40% of the population is type O, while types A and B are represented by about 26% of the population respectively. Interestingly, only 7% of Hong Kong's population is type AB.
In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
The gene for type O is 'recessive', because if you have one gene for O and one for A, then you still end up with A antigens on your cell membranes, and the same goes for O and B. In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form.
Those with type O blood should choose high-protein foods and eat lots of meat, vegetables, fish, and fruit but limit grains, beans, and legumes. To lose weight, seafood, kelp, red meat, broccoli, spinach, and olive oil are best; wheat, corn, and dairy are to be avoided.
Asia. Even though O+ remains the most common blood type here, blood type B is relatively common too. Nearly 20% of China's population has this blood type, and it is also fairly common in India and other Central Asian countries.
While over 70 percent of Mongolia's population have A and B positive types, 0.6 percent has rare blood type – the Rh negative. People with negative blood type have been observed to come from the western region of Mongolia.
As for blood group B, it is very common in India (40%) and generally quite common in South Asian countries, such as Vietnam for example (31%).
Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
Zaidi et al. reported a positive association between T2DM and the ABO blood group system; T2DM and the ABO blood group system are interrelated on a genetic immunologic basis; however, the study inferred that the individuals with blood groups type B and A have a higher frequency of T2DM [14].
Rh-null blood can be accepted by anyone with a rare blood type in the Rh system. “Golden blood” is as rare in reality as it was in ancient Greek mythology: only forty-three people in the world are known to have had this blood type.
Taken together, the authors concluded that type O and Rh-negative blood groups may be protective against SARS-CoV-2 infection and illness.
Dana Devine, shows that people with blood groups A or AB are more likely to have a severe COVID infection than people with blood groups B or O. The study looked at 95 patients critically ill with the SARS-CoV-2 virus in the intensive care units (ICUs) of two major Vancouver hospitals.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
In terms of demographics, around 34 percent of the Korean population are Type A and 28 percent are Type O, while 27 percent are Type B. Type AB accounts for the remaining 11 percent, according to the pollster. Scientifically, blood type differs according to the type of proteins in the blood.
They say people with type A blood are calm and collected, artistic, and polite; people with type B blood are practical, goal-oriented, and strong-willed; people with type O blood are outgoing, energetic, and outspoken; and people with type AB blood tend to have characteristics on both sides of the spectrum.
Many believe people with type O blood have an extroverted personality suited to collectivistic Korean culture and few character flaws, which may have arisen from the fact that type O blood is considered the “universal donor.”
