I'm currently experimenting with the blood type idea after discovering I am also blood type A (negative).
So far, I've found there really is something to it for some people, others not so much. Personally, I almost perfectly fit the description given by Dadamo for our blood type. After a few months of eating raw beef, I found out that it is indeed not good for my body.
How do you feel eating beef and other foods not recommended for your blood type?
Try eating turkey, chicken, wild game and/or fish. Fish in general re probably more preferable to turkey and chicken, especially if eating raw, but these meats are supposed to be the most tolerable for our blood type. The theory that we produce very low stomach acid really makes sense in every aspect for me. I am even very sensitive to acidic foods.
I love Raw Paleo and believe it is the most optimal diet for
most people, but I also believe in our diversity and blood type A's seem to have a hard time following this ancestral diet.
I am still experimenting, but have added raw, gluten-free oats to my diet for 4 days now and things are going well. I've also been cutting down on raw dairy and introducing more fruits. I am still eating raw egg yolks and make exceptions to eat beef liver when I have a chance. Since I am visiting Europe at the moment, I don't have many good constant or cheap sources of turkey or fish, but I will give these a try upon returning to the U.S. in a few weeks as I'll have better sources.
I suggest you keep looking for foods which make you feel good. I wish I could follow the Raw Paleo diet 100% with good results like most on here, but keep in mind our diversity as humans.
