Are you a Secretor or a Non-Secretor?


You may know your blood type – but do you know whether or not you're a secretor or a non-secretor? Most people have no idea that this blood typing sub-system even exists, but in truth, knowing which category you fall into can help you to make the most of your health.

The concepts of secretors and non-secretors were first introduced to the public by Dr. Peter D'Adamo's book Eat Right 4 Your Blood Type. In his book, Dr. D'Adamo posits that differences in blood type make people respond differently to various diets and medical treatments, and are the reason why some people are more vulnerable to certain illnesses and maladies than others. Each blood type, he says, has a distinct chemical reaction to lectins – substances found in foods. When a person eats a food containing lectins that are incompatible with his or her blood type, those lectins target a certain area and cause blood cells in that area to clump (or agglutinate), leading to uncomfortable symptoms. Continuing to ingest the offensive food will make the person susceptible to disease in the areas where the agglutination occurs.

Whether you're a secretor or a non-secretor is completely independent of your blood type, but just as important when it comes to understanding any metabolic dysfunctions and immune susceptibilities. Simply put, a secretor is a person whose body secretes its blood type antigens into its fluids – saliva, mucus, etc. A non-secretor does not. (Approximately 80% of the general population are estimated to be secretors.) And while no one blood type is better than the others, it is thought better to be a secretor than a non-secretor. The ability to secrete blood type antigens into your bodily fluids offers enhanced protection against outside factors such as potentially harmful microorganisms and the lectins from the food you eat. Secretors also have a more accomodating intestinal environment in which beneficial probiotic bacteria can thrive, since blood type can be used as a food source for such bacteria. Non-secretors on the other hand, because their bodies don't infuse their fluids with blood type antigens, have tendencies toward:

• Higher rates of oral disease, including more cavities – and, interestingly, habitual snoring
• Digestive problems, such as inflammation and ulcers
• A more prevalent rate of autoimmune disorders, such as multiple sclerosis
• Lungs that are more susceptible to environmental factors and cigarette smoking
• A greater risk of diabetes and heart disease
• A greater risk for recurrent urinary tract and Candida (yeast) infections
• An increased association with alcoholism
• More difficulty breaking down dietary fat and properly metabolizing calcium
• An increased intolerance to carbohydrates

Your “secretor/non-secretor” status, in conjunction with your blood type, also determines the viscosity and clotting time of your blood. So you see? Since many of your bodily functions and responses are influenced by your secretor status, knowing which you are can be a valuable tool in determining how to take the best care of yourself – and how to feel better than ever.

Secretor status

Antigens are present in the blood and, in most individuals, in bodily fluids such as saliva. If antigens are present in your bodily fluids, you are known as a ‘secretor’. If they are not present in your bodily fluids, you are a ‘non-secretor’. This fact is important for the diet, so it is important that you find out your secretor status.

Some researchers have found a correlation between Rhesus status and Secretor status. If you are unable to determine your Secretor status, a general rule of thumb is that Rhesus + usually denotes a secretor, and Rhesus – usually denotes a non-secretor. This research has not been sufficiently documented at this stage, so if possible and if available in your country, a test for secretor status should be done at the same time as the test for your blood type.

Secretors are shown as ‘1’ and non-secretors as ‘2’, for example, A1 (secretor) or A2 (non-secretor).

  1. Since Rh neg O has no antigens does that mean we are non-secretors? Janeen in Arizona

    1. It would depend if you are Rhesus O negative homozygous (O-/O-) you may still be O negative and a positive blood type. IE you could be (O-/O+) obviously depending on what your parents are.

  2. Yes, if you have Rh negative blood, there is a high chance of you being a non-secretor.

  3. So how do non-secretors better themselves? It's not like we can change our bloodtype...

    1. I don't know about this study, I'm -O and have none of the mention conditions.
      I did heard that bug bites make your immune system stronger. Eating honey is know to lessen allergies specially seasonal ones. They fabricate penicillin from the fungus ants farm in their caves. I been bit by bees, wasps, ants red and black, mosquitoes from many shapes and sizes, a spider or two...
      I'm not saying you should try this at home, but I'm strong like a bull cough cough... ha ha just joking, but over all great health!
      If you must, eat more honey, and do get bit by a couple average ants, not the giant gladiator kind just normal ones and do not try spiders...

    2. For real, and I don't know, ever since I stopped eating meat I haven't been sick. I stopped at 15 and I am about to be 17 in a few days. I used to get sick like every 2-3 months, bronchitis, menstrual problems (like bleeding for months) and all types of crazy stuff. I had a Dr from India suggest that I try out herbal life and quit the meat and animal product once my blood test came in. We ordered all types of herbs online and I build up my
      immunity and have been healthy ever since.

    3. Zakiya: Blodtype O people can not be vegetarians. They have the oldest blodtype from when we where hunters and gatherers. If they chose to be vegetarians they are putting their heath at risk with increased cancer chances and many other diseases.

  4. This theory is not true, as I am an O+ blood type and a non-secretor.

    1. That is very arrogant of you, read what it says "Some researchers have found a correlation between Rhesus status and Secretor status. If you are unable to determine your Secretor status, a general rule of thumb is that Rhesus + usually denotes a secretor, and Rhesus – usually denotes a non-secretor. This research has not been sufficiently documented at this stage, so if possible and if available in your country, a test for secretor status should be done at the same time as the test for your blood type." No one says it is 100% true. Also you could be an -/+ rather than an +/+ so could be half negative.

  7. Thank you all for this, so what can we do if we are a non secretor to better our lives?

  8. I'm actually a RH+ Heterozygous (A+/O-) and I'm a non-secretor. So even if you're a positive blood group you can still be a non-secretor if you have a plus/minus blood type.

  9. I'm RH Negative -O
    I suffer with many diseases including autoimmune RA.
    Would my Rheumatologist know the answer to this?

    1. I believe people who are Rh- who were give immunizations as children are now suffering with a broad spectrum of disease, I have psoriatic arthritis and idiopathic peripheral neuropathy, I think these immunization had anitibodies in them that our bodies cannot remove and are attacking our system.

  10. I'm A- and a secretor. I don't have the problems associated with NS so I suspected as much but got the test done to make sure. Now I can go back to the bread I love to eat. Yayyyyyyyy!! I told hubby to get the test because he is A+ and is prone to the NS problems...go figure.
