Blood type diet.
 

Anyone hear about this? It sounds way too simplistic. Seems to be based on the idea that people with certain blood types have evolved at different speeds. O type blooded human are the oldest strain basically based on what our hunter ancestors ate. AB type blooded humans are the most recent strain and reflect what should be eaten by city dwellers.

You are supposed to eat stuff on what is good for your blood type which is based on evolutionary strains. http://en.wikipedia.org/wiki/Blood_type_diet

Cannot really buy this reasoning. Has all the scientific validity IMHO of those people who used to gather information on bumps on heads and then give medical advice based upon the shape of the cranium.

I've read a couple of articles about the blood type diet and there isn't a whole lot of research to back it up.

That seems true. There are some best sellers on it but they look more like junk science than real science., i.e. something that can be disproven in a lab or other such experiment. Eat Right For Your Type :: The Official Blood Type Diet ® Site

The 4 blood types also look much older than the proponents of blood type medicine contend.

I seem to remember this book being released about 15 years ago, and lots of people jumping on the bandwagon. I think it was just another short-lived fad.

Sounds like it is revisiting now. Some people at Doggie Doo Run Run were talking about it this morning. Seems there is some speaker pushing it here in the Villages.

I read the book and was thinking about following it but then decided against it since I didn't like the food I was supposed to eat! I did wonder about it, though.

I tried this diet a few years ago. It made me so tired it took me six months to regain my strength.

I was just looking at the 96 page list of clubs in TV and there is a club "Eat Right For Your Blood Type" in case anyone is interested.

I looked into it and decided I'd have to throw out everything in the house and start over. Also, as someone else mentioned here the food I'd "get to" eat doesn't sound appetizing to me! This "diet" has been around the block and I did hear about it some years ago. Haven't actually known anyone who did it and if they did adhered to it.

Anything that's restrictive will eventually cause one to fall off the wagon due to it not being sustainable.

Anyone can write a book. Sigh, there is no scientific backup for this particular "diet" plan.

not a fan liked atkins better cause it simple

All foods contain lectins. And the author, D'Adamo, claims that if a food is incompatible for your blood type, your immune cells will attack the particular lectins in that food. Your immune cells will attack the lectins as a foreign invader. This is supposed to put an unnecessary burden on your immune system and cause a distraction from hunting down the real villains like cancer cells etc..

He claims he has tested all the blood types with all the different lectins from various foods. Evidently, lectins can be purchased especially for research purposes. So, if you put a drop of type O blood with a pinch of certain lectins under a microscope you will see clumping if the two are incompatable.

It sounds valid but I don't know of any doctor who has published any scientific paper on this finding.

Although many people claim to feel better on his diet, it could be because his lists of acceptable foods are mostly natural whole foods. He doesn't have any fast foods on his lists. So if you just came off of a junk food regimen, you are likely to feel better eating natural whole foods.

This seems to challenge the blood type diet claims.

There was no difference in blood type re-actions based on samples from various lectins in foods.

It may be likely that it will take years of research to gain any validity in this theory. It would certainly explain why some people suffer badly from auto-immune diseases and not others. My wife is AB and the results of her blood tests have consistently registered a false positive due to the fact that her LDL's are so low and her HDL's so high. I intend to see open to this issue and see what develops over time

Do you happen to know who sponsors the Owen Foundation Website? I'm courious because in the past I have read other articles against the blood type diet but none of them were ever signed by anyone. D'Adamo may be selling wrong information to people, but at least he has the courage to attach his name to it.

FYI, my blood type is "O" so I'm supposed to eat meat but I'm doing very well as a vegan. I did eat meat prior to 2006 and did well on that too.
