5 Vital Things Your Blood Type Can Tell You About Your Health

It’s important to know your blood type in case of a need for transfusion, but knowing your blood type covers many more areas of your health than you may think. Research indicates that your blood type is a key genetic factor that influences many areas of health and well-being.

Why is it that some people lose weight more easily? Why do some people struggle with chronic illness? Why are some people more prone to stress and its negative health effects? The answer is often overlooked: it’s all in your blood type. It determines everything from how your body reacts to food, how well it fends off disease, the quality of your gut bacteria, and so much more! Instead of looking only at outside symptoms, we should instead look inwardly. One drop of blood is like your biometric fingerprint, and can tell you an incredible amount about your body.

Here are five things that your blood can tell you:


Not everyone has the same chance to face specific disease. Certain blood types may be at a higher risk for certain diseases. For example, people with blood type O have a lower risk for heart disease, but a higher risk for developing stomach ulcers. People who are blood type A have higher risks of microbial infections, but Type A women experience a higher rate of fertility. Other research has found that people with type AB and B blood have a much higher risk of developing pancreatic cancer. Find out what your illness Achilles’ Heel is, and protect yourself as much as you can preventatively.


You may think you’re just a bit more fearful and burdened by life’s stresses than most, but your blood type might be to blame, thanks to the hormone cortisol levels determined by your blood type. Blood type A people naturally have higher levels of cortisol in their bodies; they also produce more in response to stressful situations as a result. On the other hand, people with type O blood are prone to the “fight or flight” reaction to stress, which means more adrenaline floods their system than necessary. Understanding this can play a key role in mindfully managing your stress. For instance, if you are Type O, you may need to understand that it takes O’s longer to recover from stress because it is more difficult for them to clear the adrenaline from their bodies. Try upping your morning or evening meditation sessions to an hour or more. Find what calms you down and spend more time around it. Too much stress regularly can be just as negative on your health as any disease, so form a battle plan.


Blood type antigens are everywhere in your body, especially in the parts of your body that deal with the outside environment. These include your digestive tract, from your mouth to your large intestine, as well as your nasal passages and lungs. Because these blood type antigens are everywhere, they influence how your body reacts to the food you eat through several factors. For example: the lectins in certain foods bind to your blood type antigen and cause your blood to agglutinate (stick together), resulting in feelings of fatigue, headaches, digestive issues, skin problems and a host of other health issues. Luckily, there are supplements you can take to help alleviate these issues, so knowing about the problem is essential to fixing it.


You don’t want candida, diseases, or allergies, do you? Then you need a well-balanced gut, which may be more difficult for people of different blood types than others. All blood types have different gut bacteria; in fact, certain bacteria are 50,000 times more likely to turn up in people with one blood type or the other. You can thank our ancestors for this. People from different origins and places all over the world developed digestive tracts to accommodate one type of diet over another. For example, the microbiome of certain people developed to break down carbohydrates much more efficiently (blood type A). People lacking this ability (blood type O) tend to store carbs as fat.


You hear the advertisements for Hydoxycut or Weight Watchers or the paleo diet, and how widely successful it is for those believers. Well, they are all valid methods of losing weight, but just because it works for some people doesn’t mean it was meant for you. Based on the facts listed above, it should be clear that based on your blood type (and a plethora of other factors), your body does different things with the same exact foods everyone else is eating. If you are serious about losing weight, it’s essential to know your blood type so that you can map out what foods will work best for you in weight loss, inflammation reduction, energy boosting, and overall holistic health.

What if there is a way to repair your body’s susceptibility to disease and age-related degeneration? Scientists are studying it now, with the hopes of finding the path to immortality. Learn more in the revolutionary documentary The Immortalists.
