There has been a lot of attention in the alternative medicine world given to eating for your blood type, or the blood type diet. Two naturopaths, a father and son, came up with the blood type diet after many years of practicing and noticing that certain people did better on different diets and they believed that the pattern they were seeing was actually correlated to the person’s blood type and hence the blood type diet was born. Their book is called Eat Right For Your Type by Peter J D’ Adamo.
The Blood Type Diet Regimen
Their dietary regime for A, O, B, and ABO blood types are in my opinion, very detailed and tedious if taken to the full extent. However, For every blood type except for AB, they recommend cutting out ‘wheat’ which in general leads to people eating more unrefined whole grains and feeling much better from this change alone (for many reasons besides what your blood type is see my article on grains).
It is scientifically plausible, I believe, that people with different blood types may respond differently to certain foods, but it has not been studied in a rigorous fashion thus far. For some of the blood types, the authors recommend cutting out more than one entire food group.
Blood Type Diet Recommendations: Meat And Dairy
So someone with asthma or sinus problems, for example, would be advised in these systems to cut out dairy completely. I have seen patients have subjective improvements in these conditions when they cut out dairy, and for certain people I do recommend restricting especially cow’s mild dairy products.
Blood Type & Personality Claims
My main complaint about this is that it suggests that mind body practices like yoga and tai chi are not beneficial to everyone, which is SO UNTRUE! Practices like yoga are good for everybody, regardless of blood type or personality, but their yoga practice should be different and tailored based on their individuality and needs.
If there are certain pieces from this dietary approach that you want to try, as long as you continue to eat a healthy balanced diet you should be able to see if some of the major themes apply to your body. Just by being more ‘tuned in’ to your body during the process, you may gain some useful knowledge about the best dietary approach for you–I call this ‘Intuitive Nutrition’ and believe it is a powerful way to empower yourself through the foods you choose to put into your body.
If you don’t know your blood type, you can ask your family doctor if they have it on your file. If not, it can be discovered with a simple blood test.
