Does blood type tells us how should we eat?

I stumbled upon this video where a presenter talks about caveman diet,

http://www.youtube.com/watch?v=WX3xRjeNqoM

Though she calls the diet the "caveman diet", but she also says that blood types tells us how should we eat.

Well, I can agree on the avocado and coconut but I happily drink coffee every day and just ate 3 eggs (and bacon) for breakfast. My only complaint about eggs is they aren't very satiating. I also LOVE, LOVE, LOVE cabbage raw, cooked and fermented.

I didn't necessarily *find* Paleo *through* the blood type diet (I'm type O, also), but I found it very interesting how similar the two were once I started reading/learning about Paleo. I'm pretty sure I'm sensitive to eggs, and plain avocado makes me sick...just a couple examples of "avoids" that don't work optimally for my body though they are revered in Paleo nutrition. I wouldn't base my entire diet on my blood type, but I think it makes sense to an extent. At the very least, it is "useful/interesting/informative," as you mentioned.

Diamonds are the ultimate in paleo accessories! "Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometers (87 to 120 mi) in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth)."

I'll also note that these sorts of beliefs tend to flourish by means of confirmation bias. Every time someone reads a book they take the message in and absolutely hate contradictory evidence (myself included) because it makes them feel like they wasted time and money in something bunk. So all evidence that affirms the message is emphasized in their mind and all evidence that contradicts it is dismissed.

Loren Cordain, author of The Paleo Diet has much to say about blood type diets, none of it good. http://naturalsportsmedicine.blogspot.com/2010/05/critical-examination-of-blood-type.html

Basically he says that the blood type diet isn't based upon factual information and that any diet that ends up prescribing a paleo diet for half of its readers will inevitably see some success.

So as type A+ I should do best as a vegetarian. BWAHAHAHAHAHAHAHA HAHAHAHAHAHA HAHAHAHA WAHAHAHAHAH AHAHAHAHAH EHEHEHEE. STFU.

This presentation explains nothing and is poorly formed. There is no evidence that combining foods is worse than not combining foods. Any time someone gets in front of an audience and starts blathering about stuff like this it is time to tune out unless they have references and go into specific scientific mechanisms which you can evaluate for yourself.

I'll also note that these sorts of beliefs tend to flourish by means of confirmation bias. Every time someone reads a book they take the message in and absolutely hate contradictory evidence (myself included) because it makes them feel like they wasted time and money in something bunk. So all evidence that affirms the message is emphasized in their mind and all that contradicts it is dismissed and forgotten about.

I found Paleo thru the blood type diet (as I'm type O). It seems to have a bad reputation in this community, but I must say this: every vegan I know with health or weight problems is a type O, and every seemingly fit and healthy vegan I know is a type A. Also, I find that most of the paleo foods that I am sensitive to (coconut, eggplant, eggs, coffee, cabbage...) are 'bad' for O's according to the blood type diet. I know very little about the legitimacy behind the science, but by personal experience I have found it useful/interesting/informative.

Chris Kresser dismantles the blood type diet quite nicely on one of his podcasts. I can't remember exactly which one but possibly around episodes 3-5

I'm type A and I did terrible on a vegetarian diet. Gained a gazillion pounds. Now I eat Paleo, low carb, moderate protein and high (sat) fat and I'm doing great. Got rid of 40 pounds and still counting.

So, to me the bloodtype diet is nonsense. I don't believe in "one diet fits all", but if the bloodtype diet was right, I should have thrived on the vegetarien diet and I SO didn't!

I agree with LiveBigger...go to the blood type forums and you will find so many success stories regarding that way of eating. I am an O too and thrive on red meat and veg...not so much with pork, coconut, cabbage and other AVOIDS. So, that information is definitely part of my experimentation even though there is a tremendous amount of scientific criticism thrown at it. But, I am paleo first, then blood type. I won't be hitting the adzuki beans, rye grains or sesame oil anytime soon.

Using blood type as way to inform eating is such a tiny bit of info extrapolated from the larger picture. I find that some things work for me at times or don't given so many factors including: stress, environment, type of exercise, time of the month, illness, quality of my food, how I cook the food. Sure, maybe the blood type diet could have merit (I'm not saying it does/doesn't) but not as the sole determinant.

That was a very rushed presentation.. I guess she was only allotted 5 minutes?
I am skeptical of the blood type diet. I am type B, so I can eat anything... except Chicken?! I have an open mind though and I would do the research to look into this.
The idea of eating foods separate from each other saddens me, I love cooking and throwing things together based on taste.. not what it will do to my insides lol.
