Blood types are a unique sugar found on the outside cells. These sugars can be found in all different places inside and outside the body, including cells that aren’t blood cells. There are over 300 blood types, but the typings that doctors use the most are the ABO system and the Rhesus positive or negative system. Dr. Brody utilizes a third blood type, the Lewis typing, in his treatment plans.
The Sugars’ Role
When these sugars attach to other proteins or other molecules, they can sometimes cause a reaction. For instance, when a Type A sugar bonds with a chemical from lima beans, it causes a process called “agglutination” or sticking together. When the body sees this process, it activates the immune system via the lectin pathway to clear the potential blockage and causes inflammation. This type of reaction is important in the role of conditioning the gut and many other factors.
These sugars on the outside of the cells are our first line of defense against bacteria and viruses, all of which can be coated with their own sugars. How these sugars interact, whether agglutination or something different, can cause infection. These interactions are why some blood types are more susceptible to other diseases than other types. However, having an increased risk isn’t a guarantee that you will get the disease or another type won’t. It just means it can be easier to get. For instance, the Black Death primarily infected Blood Type O’s, but not every type O was infected.
Blood Type A
Making up 40% of the population, Blood Type A is one of the older blood types. Type A’s thrive on a primarily vegetarian, pescatarian, or Mediterranean diet due to their low levels of stomach acid. Type A’s also have the stickiest blood type sugar, so their cells are more likely to stick together. Unfortunately, this comes out as a higher risk of different diseases based on their subtyping.
Blood Type A uses a genetic factor to split into A1 and A2. Type A1 sees their sticky cells as a higher risk of cancer, as the contaminated cells stick to other cells and infect them before duplicating. Research has found that a lectin found in escargot, or snail, is able to help the body identify which cells are cancerous. Type A2 has their stickier cells lead to a higher risk of cardiovascular disease, as their cells can clot and increase the blood pressure necessary to send blood throughout the body. Cholesterol tests are a great preventative measure for a Type A to watch their heart health, with the goal being a number under 200.
Beneficial bacteria for Type A’s include Bifidobacterium bifidus, lactobacillus plantarum, and lactobacillus reuteri.
Blood Type AB
Blood Type AB can be found in about 1% of the global population, and is known as the “Universal Receiver”. People with the AB typing are incredibly rare because they have two genes sharing dominance instead of one in command. This typing is rare in nature and wasn’t found until just prior to 900 C.E. in Europe.
Because of the co-dominance, the immune system in ABs doesn’t produce antigens for type A or type B. This leads to an immune system more susceptible to disease. Type AB’s are more prone to bad urinary tract infections, staph infections, shigella infections, diphtheria, klebsiella infections, typhoid, and salmonella.
Beneficial bacteria for Type AB’s include Lactobacillus casei, Saccharomyces boulardii, and Bacillus coagulans.
Blood Type B
Making up about 20% of the population, Blood Type B’s have been traced back to a stretch of land across lower Europe, the Middle East, and down and around Asia.
Due to a genetic mutation, Type B’s have a lack of nitric oxide used to open up the body and improve circulation. This can make them more responsive to changes in climate. They also have a naturally higher level of cortisol. Type B’s are at a higher risk of autoimmune disease and pancreatitis than the other blood types. Blood Type B’s have a higher risk of shigella, pneumonia, strep, the flu, klebsiella infections, and amoeba diseases.
Beneficial bacteria for Type B’s include Lactobacillus bulgaricus, Bacillus coagulans, and Saccharomyces cerevisiae.
Blood Type O
The oldest blood type, Type O’s make up 40% of the population. Dating back as far as we can track, Blood Type O shows up in both ancient tribes and current members of isolated tribes. Part of what made the Black Plague so deadly was the susceptibility of Type O’s. Known as the “Universal Donor”, Type O’s can donate their blood with anyone sharing their Rh typing.
Hunting and gathering have been in the blood of Type O’s for generations. Because of this, Type O’s thrive with a high meat, low carb diet, and vigorous exercise. They have the highest levels of stomach acid, or hydrochloric acid, so they can digest dense foods like meat easier. Because of their hunter nature, they have genetic mutations in MAOa and DBH gene which convert neurotransmitters like dopamine into adrenaline. These elevated levels of adrenaline necessitate higher levels of physical exercise.
Blood Type O’s are more susceptible to candida infections, cholera, hookworm, and the bubonic plague.
Beneficial bacteria for Type O’s include Streptococcus thermophilus, Lactobacillus rhamnosus, and Saccharomyces boulardii.
Rhesus Blood Types
A single protein on the surface of red blood cells splits the Rhesus blood type into Rh positive or Rh negative. The majority of the population has the protein that indicates Rh positive. Rh negative doesn’t have any predispositions to disease or illness.
Lewis Blood Types
The FUT2 gene splits the Lewis Blood Type as either Lewis A or Lewis B. 80% of the population are secretors, meaning that their body secretes their blood typing sugar into the mucous membranes where the body touches the outside world. The eyes, nose, ears, and mouth are all examples of the mucous membrane. These sugars act as a form of protection against outside infections, like a moat around a castle. The remaining 20% of the population who aren’t secretors don’t have this protection and can be more vulnerable to infection.
