Millions of people — including trauma patients, burn patients, cancer patients, and people with certain diseases — benefit from blood transfusions each year. Your blood type is inherited from your parents, much like your eye and hair color. Take a look at our genetic chart. Latest studies have shown that someone in the US needs a blood transfusion every 2 seconds each day in the United States.
The average person can only donate 1 pint of whole blood in a single donation and the shelf life is 42 days, which is why the need to keep replenishing the supply to meet demand is great. Blood Types. B Blood Type.
Blood type distribution by country
B negative red blood cells can be given to both B and AB patients. B negative patients can only receive blood from other B negative donors or from type O negative donors who are the universal donors. Since both of those types are fairly rare, the Red Cross works hard to ensure that sufficient supplies are always available.
B positive red blood cells can be given to both B positive and AB positive patients. B positive patients can receive blood from B positive, B negative, O positive and O negative donors. Did You Know? Why Donations Are So Important.During the course of history, those interested in science in biology made efforts to understand the nature and peculiarities of blood.
On the basis of their experiments and researches there was made the following conclusion: blood is life due to the fact that it performs a set of functions that are vital to the normal functioning of the organism. The structure of blood stays relatively the same during all the lifetime of a person. There is a number of characteristics closely related to blood type. One of them is Rhesus factor.
What is Rhesus factor? Each of the blood types has its own peculiarities. These were the times when people started to actively move to and inhabit northern regions in different parts of the world.

By FactsKing.The B Positive blood type is extremely valuable where matching supply for the demand has been a constant challenge. However, it is the third most common blood type which is present in about 1 out of 12 individuals. This means an approximately 8. But, note that not all of the ethnic groups share the same proportions of the B positive blood type.
A and B genes are codominant in relationship, making the expression of both antigens A and B when either alleles A or B is present. Blood Group B has a B antigen on red cells with the A antibody in the plasma. Read interesting facts about blood donation here. An individual with a B positive blood type has both antigens B and Rh on the blood. A transfusion with the use of any other blood type can result to an immune response. Male individuals can donate blood for up to 4 times each year while females can give blood for up to thrice a year.
However, blood type B plasma can only be given to type O and B recipients. Rh Factor is an additional marker in the blood. This can be classified as either Rh positive or Rh negative. This marker is only used for genetic differences. A B Positive blood type is Rh positive. Also read about B Negative Blood Type. There can be challenges that Blood Type B individuals may face.
The blood type is likely linked with sensitivity to B specific lectins in some foods, higher than normal cortisol levels in relation to stress, vulnerability to autoimmune diseases, and susceptibility to slow growing viruses like lupus. However, a healthy blood type b individual can have fewer risk to diseases and believed to be more physically fit than other blood types.
Individuals with blood type B has been described to learn best through listening, reflecting, and interpreting. They are also associated to being original, flexible, creative, mystical, idealistic, subjective, globally-oriented and people-oriented. It is encouraged for blood type B individuals to follow have highly beneficial foods like eggs, low fat dairy, green vegetables and beneficial meats.
On the other hand, foods that affect metabolism productivity like wheat, corn, peanuts, sesame seeds and tomatoes should be avoided. Chicken consumption should also be replaced with foods like lamb or goat.This list concerns blood type distribution between countries and regions.
Blood type also called a blood group is a classification of bloodbased on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells RBCs. These antigens may be proteinscarbohydratesglycoproteinsor glycolipidsdepending on the blood group system. Blood group B has its highest frequency in South Asiawhere it ranks first as the largest share of the earth's population.
In Southeast Asia the share of the population is high, especially in Thailand and Indonesia, secondarily in East AsiaNorthern Asia and neighboring Central Asiaand its incidence diminishes both towards the east and the westfalling to single-digit percentages in NetherlandsNorwayPortugal and Switzerland.

It is believed that each blood type hints to a different but rich history, including where your ancestors came from, what climate they lived in, what they did for a living, and what they ate on a daily basis. It seems logical, then, that the four blood types respond to different foods in different ways.
Certain foods that are ideal for one blood type may lead to weight gain and disease in another. A large migration from the hot climate in Africa to the cold climate of the Himalayan highlands—what is now part of India, Nepal, Tibet, and Pakistan—caused quite a shock to blood type A people. It is believed that blood type B started as a mutation in response to climate change.
It first appeared in India and in the Ural region of Asia, where there was a mix of Mongolian and Caucasian tribes. Blood type B soon became a characteristic that defined tribes of steppe dwellers as they moved through Asia. Their livelihood depended on domesticating animals, and so they ate a lot of dairy and meat. As you look further west, the B blood type can be found in people of Asian nomadic migration. Here we can start to understand the role of the blood type diet.
B blood types are flexible. They adapted from being strictly herbivorous to eating mostly dairy and meat products. Therefore, the B positive blood type diet and the B negative blood type diet include both vegetable and animal foods. Type B people are flexible and fluid but are also prone to producing high levels of the stress hormone cortisol. Diets high in certain toxins and lectins can increase cortisol levels, leading to disease and inflammation.
Overall, type B people are strong, fit, and mentally balanced. They are not as susceptible to many of the diseases that plague other blood types.
By following a B blood type diet, they can live long, happy, and healthy lives.
The B blood type diet is diverse and rich in meat, dairy, fruit, vegetables, and grains. However, there are specific foods that should be avoided by people looking to follow a B positive blood type diet or a B negative blood type diet. It all has to do with the way that certain lectins—proteins in your food—react with your blood.The novel coronavirus causing COVID seems to hit some people harder than others, with some people experiencing only mild symptoms and others being hospitalized and requiring ventilation.
Though scientists at first thought age was the dominant factor, with young people avoiding the worst outcomes, new research has revealed a suite of features impacting disease severity. These influences could explain why some perfectly healthy year-old with the disease is in dire straits, while an older year-old dodges the need for critical interventions. Underlying health conditions are thought to be an important factor influencing disease severity.
Indeed, a study of more than 1. The most commonly reported underlying conditions were heart disease, diabetes and chronic lung disease. The risk of dying from the infection, and the likelihood of requiring hospitalization or intensive medical care, increases significantly with age. The trend may be due, in part, to the fact that many elderly people have chronic medical conditions, such as heart disease and diabetesthat can exacerbate the symptoms of COVID, according to the CDC.
The ability of the immune system to fight off pathogens also declines with age, leaving elderly people vulnerable to severe viral infections, Stat News reported. Diabetes mellitus — a group of diseases that result in harmful high blood sugar levels — also seems to be linked to risk of more severe COVID infections. The most common form in the U. As a result, the sugar that would otherwise move from the bloodstream into cells to be used as energy just builds up in the bloodstream.
When the pancreas makes little to no insulin in the first place, the condition is called type 1 diabetes. In a review of 13 relevant studies, scientists found that people with diabetes were nearly 3.
Even so, scientists don't know whether diabetes is directly increasing severity or whether other health conditions that seem to tag along with diabetes, including cardiovascular and kidney conditions, are to blame.
That fits with what researchers have seen with other infections and diabetes. For instance, flu and pneumonia are more common and more serious in older individuals with type 2 diabetes, scientists reported online April 9 in the journal Diabetes Research and Clinical Practice.
In a literature search of relevant studies looking at the link between COVID and diabetes, the authors of that paper found a few possible mechanisms to explain why a person with diabetes might fare worse when infected with COVID These mechanisms include: "Chronic inflammation, increased coagulation activity, immune response impairment and potential direct pancreatic damage by SARS-CoV Related: 13 coronavirus myths busted by science. Mounting research has shown the progression of type 2 diabetes is tied to changes in the body's immune system.
No research has looked at this particular virus and immune response in patients with diabetes; however, in a study published in in the Journal of Diabetes Researchscientists found through a review of past research that patients with obesity or diabetes showed immune systems that were out of whack, with an impairment of white blood cells called Natural Killer NK cells and B cells, both of which help the body fight off infections.
The research also showed that these patients had an increase in the production of inflammatory molecules called cytokines. When the immune system secretes too many cytokines,a so-called "cytokine storm" can erupt and damage the body's organs. Some research has suggested that cytokine storms may be responsible for causing serious complications in people with COVID, Live Science previously reported. Overall, type 2 diabetes has been linked with impairment of the very system in the body that helps to fight off infections like COVID and could explain why a person with diabetes is at high risk for a severe infection.
Not all people with type 2 diabetes are at the same risk, though: A study published May 1 in the journal Cell Metabolism found that people with diabetes who keep their blood sugar levels in a tighter range were much less likely to have a severe disease course than those with more fluctuations in their blood sugar levels. People with type 1 diabetes T1D are also at elevated risk of adverse outcomes, a small study published in Diabetes Care suggests.
Nearly 4 in 10 people had to be treated in a hospital. And nearly a third experienced diabetic ketoacidosis — a potentially deadly condition in which the body experiences a shortage of insulin and blood sugar levels rise dangerously high. The average patient was about 21 years old, suggesting that risks could be potentially higher for older age groups.
People with conditions that affect the cardiovascular systemsuch as heart disease and hypertension, generally suffer worse complications from COVID than those with no preexisting conditions, according to the American Heart Association.
That said, historically healthy people can also suffer heart damage from the viral infection.The first Asian nomads are your ancient ancestors if you have B-positive or B-negative blood, claims Peter J. D'Adamo, the creator of the blood type diet. According to D'Adamo, following a diet that restricts or eliminates the foods these nomads would not have eaten will help a person with type-B blood lose weight, feel more energetic and avoid medical problems.
Ina study published in "Plos One" concluded that there is no evidence to support the premise underlying the blood type diet. Before you start any part of the plan, talk to your doctor.
A person with B-positive blood is told to avoid all forms of wheat on the blood type diet, including whole-wheat bread products, durum wheat products, bulgur, wheat germ, wheat bran, shredded wheat and cream of wheat. Consuming wheat will supposedly increase the chance of diabetes and weight gain. In addition, type-B people should avoid buckwheat, rye, couscous, soba noodles, wild rice and cornmeal. Chicken, goose, duck and quail are not recommended for type-B individuals, as D'Adamo claims that chicken in particular contains compounds that can increase a type-B person's risk of immune problems and stroke.
While lamb, venison, mutton and some types of fish are recommended, the blood type diet also discourages people with B-positive blood from consuming any type of pork, anchovies, striped bass, octopus, smoked salmon and shellfish like mussels, shrimp, oysters and lobster.
Unlike the diet advice given to type-A and type-O people on the blood type diet plan, type-B people are allowed dairy products in moderation, including cow's milk, eggs, buttermilk and cheeses such as cheddar, Swiss, Monterey jack and Brie.
But they are instructed to avoid ice cream and three specific types of cheeses: string cheese, blue cheese and processed American cheese. Certain plant-based proteins should be considered off-limits for people with type-B blood, contends D'Adamo. These include peanuts, which he says will inhibit the liver and cause a drop in blood sugar, as well as sesame seeds and lentils, which allegedly prevent proper nutrient absorption in type-B individuals.
10 B Positive Blood Type Facts
Cashews, pistachios, black-eyed peas, pinto beans, black beans, pumpkin seeds, sunflower seeds and tofu are examples of other restricted foods. D'Adamo encourages people with B-positive blood to enjoy a variety of fresh fruits and vegetables but cautions them to steer clear of pomegranates, coconuts, rhubarb, all types of olives, artichokes, radishes, tomatoes, avocados, pumpkin and mung bean sprouts. Corn, which D'Adamo says will slow a type-B person's metabolism and increase his risk of diabetes, should be particularly avoided.
The blood type program advises all people to eliminate or restrict processed and commercial foods from their diets, but it especially warns type-B individuals to avoid consuming carbonated beverages, including club soda, regular or diet cola and seltzer water. They are allowed to consume beer and wine in moderation but should not have distilled liquor while following the plan. Nutrition Diets Special Dietary Considerations. Michelle Kerns.
