Blood Type Nutrition 

Without a doubt, the nutritional plan most trending is the Ketogenic Diet, followed by the Mediterranean Diet, Vegan Diet, as well as several diet meal plans where you purchase their branded foods.  We will look into all of these each week in this segment, covering the theories, benefits, requirements, menus, recipes, and resources.   

It’s important to be well informed when making lifestyle changes for you and your family.  Truth is, not one nutritional plan will be the best choice for everyone.  There’s a reason for that.  Our genetic codes are unique.  What may work for one, may not work for another.  This is often why someone may have great success with one program, while another gains weight, experiences issues with allergies, sluggish, brain fog, or digestion.  All this, not knowing their bodies are reacting to their dietary changes.  In making your educated choices for your nutritional needs, keep this in mind.  Sometimes, drastic changes in our nutrition can cause a negative response, depending on our personal wellness level.  Some of the best advice I received years ago in this matter, was to choose two or three changes, foods, or meals for couple of weeks, and pay attention to my body’s reaction. The reason for this is two -fold:  A complete overhaul of our kitchen and lifestyle can be overwhelming and stressful.  Secondly, our bodies have the chance to adapt to the positive changes we’re making.  After two weeks, I could see and feel the benefits of the changes I had made, without suffering the undo stress of an overhaul.   This made me want to learn more, and make the commitment to work towards a total lifestyle change.   

Understanding now that our genetics does play a role in how well we respond to nutritional choices, let’s take a look at what actually happens.  Enter what’s called Blood Type Nutrition.  Coming from the body building and fitness world, I didn’t want to hear anyone telling me what I can and can’t have.  I had already tried every extreme out there at the time.  However, when my body began to crash, and no longer was responding well to anything, I listened to a doctor explain to me what was happening in my body.  Fast forward over 20 years later, this “intuitive” eating is always my go-to, my nutritional foundation, no matter what is trending that I want to try.  I can always look back at these genetic, biological truths if I’m experiencing something negative, or not achieving the results others are.   

Taking from Dr. Joseph Christiano’s book “Blood Types, Body Types, and You”, providing your body with the best nutritional program for your specific genetics can greatly help you maximize your genetic potential.   


Each blood type has different characteristics that allow it to eat, digest, and assimilate food best for that group.  Type Os are blessed with strong stomach acid and powerful enzymes that can metabolize almost anything, even some for not recommended for them.   

What happens when we eat food not compatible with our blood type?  Agglutination happens, which can be explained as followed: 

Your body has antibodies that protect it from foreign invaders. Your immune system produces all kinds of antibodies to protect you and keep you safe from foreign substances.  Each antibody is designed to attach itself to a foreign substance or antigen.  When your body recognizes an intruder, it produces more antibodies to attack the invader.  The antibody then attaches itself the intruder and a “gluing” effect (agglutination) takes places.  In this way, the body can better dispose of these foreign invaders.   

When it comes to eating foods that are not compatible with your blood type, this “gluing” effect can take place in the digestive system, joints, liver, brain, or blood.  If this pattern continues, this agglutination can cause havoc in your body systems. Agglutination of cells, or clumping, will eventually break down the function of that particular system and lead to health problems.  This is why we may experience some obvious benefits from some nutritional programs, but eventually our systems reject it, or go backwards in progress.    

In “Blood Types, Body Types, and You”, Dr. Christiano explains how foods that are incompatible for your blood type will slow down your metabolic rate, making it difficult to lose weight and possibly even causing weight gain.  Dietary lectins are found in most foods.  These lectins work either on behalf of an individual or against them, depending on whether the food is compatible wit their particular blood type.  When a food with a dietary lectin is beneficial for the, it is because the lectins function as scavengers that remove debris and toxins from the various systems in the body—liver, blood, intestines, etc.   

Foods with dietary lectins that work against the normal bodily functions of the individual are considered “avoid” foods, and should be avoided, or at most, as a treat, less is best.   Overall goal would be 80/20, eating closest to your individual blood type.  

On the other hand, eating foods compatible to your blood type is like medicine to your body, able to assist your body in detoxifying and healing all systems.
