I had the book Eat Right For Your Type, and recently started looking through it again. It's pretty interesting, but I'm not sure how much of it is actually BS or not.
For instance, it states that O blood types do better on caveman hunter gatherer type diets and intense exercise, seeing as this was the first blood type humanity originally started out with. Apparently O types have more acidic digestive systems because of the amount of red meat that they consumed. Often times O types will be lactose intolerant or have allergies to gluten because their bodies just can't process those types of foods. It says that as our species started moving on from being hunter gatherers to relying more so on agriculture, the A blood types then evolved and were able to better process that type of vegetarian diet. They have a harder time being able to digest red meat. Apparently B types came from the nomads in the Himalayas where people started domesticating animals and relying on meat and dairy, therefor, B types are one of the only types who can better process dairy. AB types are a variation of both.
What do you all think? Anyone have any experience with these types of diets? Do you think this has some logical backing to it, or is it total bullshit?
Just for the fun of it I put up a poll.
