Eating According To Blood Group?

[Faheem Shehadeh]

hey 
I have been bumped into a book lately witch speaks about diet according to the blood type (A, B, AB, and O).
and also there is a lot of websites regarding this topic, now if this is true I probably was eating wrong thru all of my 28 years.

what do you people think about it? 
wold love to get some notes from someone who knows.

Thanks and Regards.

I've read the book and I like it. There is some truth to it, but only just a little. Some of the information in the book didn't make much sense and is somewhat outdated. It was written in the 70s or 80s if I remember it correctly. For instance, my blood type is 0 but the book said I should base my meals on more protein and fat as opposed to carbs. At the same time, it said I should eat some grains, which doesn't make sense. Also, I would imagine your metabolic type plays a much more important role. The blood group diet is a nice read, but the Metabolic Typing Diet by William Wolcott is a lot better if you want a nutritional plan that suits your genetic blueprint.

"Choosing a diet based on your blood type is like deciding on what gas to put into your car based on its color." - Dr. Brad Schoenfeld

There have been 14 studies that I'm aware of being reviewed and surprise, surprise - No evidence supporting the idea of decreasing cardiometabolic risk factors in groups that were supposedly "a match".

However what they DID find is that certain diets* improved blood markers no matter the blood type.

*I don't mean a diet perceived per se like veganism, ketogenic etc, rather an overall energy balance and micronutrient intake.

There is a lot of websites regarding lots of topics, which doesn't make them more or less true.

In general, I'd say - the simpler the idea is, the lesser is likelihood it will work. Yeah, genetical blueprint, blood type match, acidity - It sounds appealing, but the more You will actually get into details and science (or lack of it) behind those ideas, the more You will be capable of making a distinction between what makes sense and what doesn't simply even apply to human physiology.

Websites, blogs, YouTube and even a big part of the library is a weak and very unreliable source of information - It is more of a gamble, You might click and see someone knowledgeable or not.
And You won't know which one is which.
