Research shows that blood type Rh-negative has more IgE allergies than Rh+. In fact, Rh-has the highest rate of immediate allergies of all blood types. The graph at right is an example. This biotype especially reacts to nuts and beans, but also to eggs, some meats, gluten grains and nightshades, as shown below. Their worst allergen is peanuts, a native American food. IgE Scores of 500-750 are mild, 750-1000 are moderate, and 1000-1250 denote strong allergies. Blood type Rh-negative also displays delayed allergies, including: strong IgG allergens, and some T-cell allergens.

I was allergic to eggs, grass, pollen, ragweed, and cats as a child. I am sensitive to medications. I outgrew my allergies but interestingly when I was pregnant with a few of my rh- children I was allergic to shellfish (I craved shrimp). I am A- and 4 of my children are because their dad was also A-. Perfect apgars at birth and when I eliminated the vitamin K vaccine at birth they were not jaundiced.
Interesting ,I have horrible sinus infections used to be once a year then twice a year now 3 times a year. I am currently on a month of antibiotics ,steroids and nasal spray despite taking natural herbs. I have always been one to get sick with colds,which used to always settle in my lungs when I was younger . I have been wanting to ask my doctor to do a allergy test on me I hear they can draw a vile of blood and test that way now. I am B-.
I am A- Rh neg and don’t have any of these allergies.
Happy you do not have the allergies! It is no fun! A- as well
I am rhd negative & have been a coeliac for the past 25 years also dairy free & allergies to mushrooms & strawberries ans can not tolerate vegetables high in iron so most of the above is more than true for me !!!!
I have celiac too, it is not an allergy its a autoimmune disorder, totally different.I also as a kid had a lot of raw milk cuz my grand papa had a dairy farm and had no problem now I have trouble with milk products. I can still eat dairy but its not like it was its full of chemicals

My O neg daughter could not tolerate dairy at a young age. Now she can handle small amounts of milk or cheese. No eggs though …
Boy, I’m lucky not to be allergic to any known plant, animal, fabric, or food and I’m A-. I haven’t even been sick for 6 years now, not even a cold or the flu so…anyone want some of my blood? It appears to be quite resistant hahaha =P
I’m A- too along with my son and daughter. In the last 3 years since having my boy I have had hives and rash EVERY day (DRIVES ME NUTS), no clue to what or why, never had a problem before. Test after test only to be told by alligest that I have to many mast cells! Gee, I paid $230 to be told what I already knew, What I need is to know why so I can fix it! Doc’s way of a quick fix is offering me antihistamine’s to live on every day, In regards to our blood being resistant, I WISH!!!
I wish I was resistant to allergies as well! Spring time is gorgeous but the pollens kill me!
Gee, I have RH A negative and don’t find myself allergic to any of the foods listed and as a matter of fact, they are my favorites.
I also loved eating nightshade pie when i was a child. So therefore I am not sure i can believe a chart such as this. nothing has ever happened to me by eating any of these foods and I drank milk by the gallon with cream on top.
I appreciate your opinion Penny. These charts do not mean that everyone that is your type is allergic, just the allergy is most common with that type.
I am also A- and I am. Not everyone that has the same type of blood we have the exact same allergies…The allergy type is “common” with this type. That is why the post is “common allergies” by blood type. I am happy you dont have the allergies I do. They are horrible at time for me. I have to avoid several foods.
I agree with the eggs definitely, though if well cooked I can tolerate them. Lots of other foods give me acid and wind.
Is your blood type O Chris. My main issue with food is bananas, and some other fruits…like melons.
