When it comes to dieting, one size does not fit all. Everybody
has different needs depending on the specific chemistry of the
individual. This gets to the heart of why the blood kind diet works so
well. Each individual follows a diet based on their specific blood type.
This article will explain the scientific principles behind blood type
diets. It will also provide a summary of what foods you should eat
depending on your blood kind.
The most important factor when determining blood type is whether or not the red blood cells carry antigens on their surface, and if they do, which antigens they carry. Individuals with Blood Type O carries no antigens on the surface of their red blood cells. Individuals with Blood Type A carries A antigens. Blood Type B carries B antigens. Blood kind AB carries both A antigens and B antigens.
Recent research has indicated that blood type is closely associated with the type of bacteria you have living in your gut. More specifically, there is an association with blood type and the assemblage of bacteria that lives in your gut because there are actually hundreds of species. This assemblage of bacteria in your gut is commonly referred to as your microbiome. These bacteria are also sometimes called your microbiota, microflora, or just plain flora. You can also think of your microbiome as a bacterial ecosystem living within your body where the different species of bacteria live synergistically. The diversity of this flora is enormous, with a healthy gut containing 500-1000 bacterial species. The quantity is also enormous. A single person will harbor more than one-hundred trillion bacteria! In fact, there are ten times more bacteria than there are human cells in the body. In essence, we are a symbiotic being with bacteria as the dominant being.
Blood kind antigens are densely present in the gut and in the mucus lining the gut. Furthermore, gut microflora eat these antigens. Many bacteria prefer to eat one type over another. Scientists are in the process of testing each of the bacterial strains that are present in the gut of different individuals. So far, approximately fifty percent of the strains have been found to be strongly associated with a specific blood type. In fact, this association is so strong, there are certain bacterial strains that are found to be 50,000 times more likely in a individual's gut with Type B blood than with any other type.
The human gut is essentially an anaerobic bioreacter with trillions of bacteria at the control board. Gut bacteria synthesize vitamins, help digest food, and trigger different genes to turn on and off. They can even tell your body how much fat to store or burn. Foods that would make one person gain weight would not make another person gain weight. In other words, if a person eats food that their gut bacteria can't handle, it affects the entire health of the individual and he or she may gain weight.
The microbiota in the gut have evolved with human populations as we have changed our eating habits. Type O blood and the enterotype associated with it is most similar to that of hunters and gatherers who lived 30,000 years ago. Type B blood, and the enterotype associated with it, is most similar to that of nomadic people who lived 20,000 years ago. These people herded sheep, goats, and other animals for meat and dairy foods. Type A blood, and the enterotype associated with it, is most similar to people who depended on grains and legumes from agriculture started only 10,000 years ago. Finally, Type AB blood, and its associated enterotype, is a fairly recent event occurring only one to a few thousand years ago, as individuals with Type A blood mated with individuals with Type B blood.
In a landmark scientific paper published in the highly prestigious peer-reviewed journal, "Nature," an international consortium of scientists found that microflora in the gut fall into three distinct clusters or types. These have been dubbed "enterotypes," similar to the word "phenotype" and also "blood type." This discovery could revolutionize medicine, potentially offering a more personalized method of treatment for a variety of diseases including obesity, Crohn's disease, type 2 diabetes, autoimmune disease, and even cancer. Enterotypes may end up being important in how a prescription drug is metabolized in the body. We already know it is important in how a patient will respond to a particular diet.
Here were the three types identified:
1. Type 1
Dominated by Bacteroides species
2. Type 2
Dominated by Prevotella species
3. Type 3
Dominated by Ruminococcus species
It should be noted that each type is also composed of other signature species to that particular type and the relative abundances remain relatively constant between the different enterotypes. Here's what made these natural clusters, or enterotypes, so intriguing. They were not correlated, even weakly, with ethnic origin, nation of residence, gender, age, or diet! However, we do know that blood type corresponds to the type of bacteria one has in their gut, assuming they are healthy. Keep in mind, however, that in unhealthy people, the natural biome becomes disrupted. In many cases, inflammation sets in and bad bacteria are able to proliferate and become dominant.
While sweeping generalizations about using enterotypes to determine medical treatments may be premature, we already know enough to know that blood types and enterotypes dictate which foods should be eaten or avoided for optimal health. Here is a general summary:
Blood kind O
It is best to eat a high protein low carbohydrate diet. Avoid wheat and eat a gluten free diet. Eat lean meats of all types including chicken, beef, buffalo, venisen, and fish. When eating red meat, eat grass fed (pastured) to get more conjugated linoleic acid (CLA) that will help you burn fat. Individuals with Blood Type O tend to have a low functioning thyroid. Therefore, cruciferous vegetables like brocoli, kale, and brussel sprouts should be avoided as they have goitrogens that inhibit the thyroid. Eating kelp and other sea vegetables high in iodine can help to regulate the thyroid.
Blood kind A
Eat mostly vegetarian with moderate portions of chicken and seafood at one meal per day. Eat more seafood than chicken. Avoid red meat because Blood Type A individuals cannot digest it well and this can lead to it rotting in the gut and bad bacteria taking over. Eat a wide variety of vegetables and fruits because individuals with Blood Type A thrive on these. Directly opposite from Blood Type O individuals, you can load up on cruciferous vegetables and grains. The bacteria in your gut will help you digest these and obtain nutrients that would be otherwise unavailable.
Blood kind B
Eat red meat, fish, seafood, and vegetables. Eat a wide variety of vegetables including cruciferous vegetables. Avoid chicken because chicken contains a protein that individuals with Blood Type B cannot digest well. Chicken will cause bloating, improper digestion, and an imbalance to the gut flora. Blood Type B individuals have gut flora that allows them to obtain more nutrients out of dairy products than another other blood type. Therefore, drink plenty of milk and enjoy dairy products like yogurt, cheese, and kefir. If you have Blood Type B and you are lactose intolerant, this is sign that your gut bacteria are not balanced. Take probiotics and eat cultured dairy products for a few weeks and you should be able to start drinking milk again. Avoid wheat, buckwheat, rye, and corn. Rice, oatmeal, and quinoa in moderate portions should not cause problems.
Blood kind AB
The diet for this blood type is a bit more tricky as it lies somewhere between Blood Type A and Blood Type B. It may also vary more by individual so you may need to experiment a bit. In general, avoid chicken and eat only small portions of red meat. Seafood is fine if kept in moderation. You can eat a variety of vegetables and can tolerate wheat but, like the red meat, limit it to small portions. A variety of fruits can be eaten, with the exception of citrus.
As you can see, following a blood kind diet makes good scientific sense because it is linked to the gut flora you have. Many individuals who follow this diet a few weeks lose significant weight and have much more energy than before. This diet can also improve the symptoms for a number of chronic diseases like type 2 diabetes, Crohn's disease, and issues with the thyroid.
Conclusion
Eating foods that your gut bacteria can help you digest and assimilate can help you lose weight and avoid metabolic diseases that cause one to gain weight more easily. The antigens associated with your blood kind has a major influence over your gut bacteria composition, and thus, can be used as a guide to the type of personalized diet you should follow.
