Eat for your blood type

There is no scientific basis for these kinds of diets. It's total bollocks that sells books.

It's likely you feel better because you anticipated that you'd feel better (aka placebo effect). http://www.abc.net.au/health/dietguide/stories/2011/08/01/3313050.htm

Anything where you are required to restrict your energy intake so that it creates a deficit will result in weight loss. There exists no evidence for the claims this diet makes.

Anecdotal evidence is very poor. Sorry. The placebo effect is a magical thing.

there is some truth to it, but it is not absolute... for instance for A+ it says not to eat tomatos, but I am fine with it... but on the same token it says I should eat a lot of fish and minimal chicken/beef and no pork... I have been a pecto lacto ovo vegetarian for 12+ years and it is right for me and my body.... the key thing is avoid fads and listen to your body, it will always tell you exactly what you need...

Funny, I'm type A blood and HATE the thought of being vegan. No stomach issues here. And BTW, A- is not a rare blood type. AB neg is.

Same here. I am Type A and if i don't eat meat I get headaches. I could not be a vegan the thought of climbing to the top of the food chain so i can eat the ooze we crawled out of makes me kind of sick. I think you might want to see a nutritionist and ask them it could be one thing or two things you are eating.

Rubbish. Sorry.

Do what works for you! I just came back from a girlfriends house and she had a book sitting out called 'Eat For Your Blood Type.' She is actually having issues as well with her stomach, neck ect. She went to a naturopath and this is what he suggested among other supplements. Again, do what works for you and keep up the good work.

^ Pretty sure I'm studying medicine and there are NO reputable doctors (who practice evidence based medicine) that would recommend this diet.

Quackery quackery quackery.

I've heard of it, but I'm currently on the "eat for your taste buds" diet. But its great that you're feeling better.

sorry but are u implying that im a liar? not all doctors do but mine have and also the nurtris do....just because you dont have problems if ur A- like me does not mean the diet does not work?...this is meant to be a supprot group not oh ur a liar thats rubbish when its clearly not thats all im saying from here because this is bull coming from a support group

We are not calling you a liar, just simply misinformed. Yes, this is a support group. Support is not blindly accepted everything anyone says. Support is offering correct information when someone is misinformed.

This is a public forum where people have the right to express a difference in opinion dear heart. If you want a "support group" thread you could start one maybe titled "Eating For Your Blood Type Support Group (CLOSED GROUP)". Otherwise, this is not a supportgroup, this is a "freedom to express your own opinion even if it conflicts with the OP's" group. :-)

Several aspects of this diet just don't stand up to reason:
1. The claim about when the blood types first arose - NO NADA ZERO evidence for this claim
2. Relationship between blood type and levels of stomach acid - see 1.


Anyone can spout a lot of pseudo-science and make it sound convincing.
Then add in some desperate people (most often desperate to lose weight).
Combine this with a knowledge of the PLACEBO effect - when people think it works, it might, plus the NOCEBO effect - when people are told something is bad, it is, and hey presto, you have a money making scheme. And if you can get the less scrupulous naturopaths to sell it, then it's an even bigger money maker.

Sorry but you're just using a bogus method to restrict your calories, which is the real reason some people do lose weight on this scheme. The story about meat rotting in your gut is a beauty hey? Certainly meat can rot in your gut (not in the stomach though) if you lack adequate fibre in your diet and things don't move along. That may also give you belly ache, as there is a reaction called the gastro-colic reflux which is triggered after you eat - if everything is jammed up it can hurt. So maybe taking the meat out of your diet has effectively increased the percentage of fibre, who knows why you feel better.

If you were experiencing stomach pain after eating, you need to be investigated for Helicobacter infection; Crohn's disease; coeliac disease; reflux;

So my take on this is - go ahead and continue eating in the way that is not triggering the stomach aches. Make sure you're getting appropriate amounts of macro and micro nutrients. But don't waste your money on these books, it just encourages the snake-oil salesmen.

And I've included some figures from the Victorian govt health website which show type A blood groups are very common, the 2nd most common in Australia.


Blood groups in Australia
A person’s blood group is described by the appropriate letter (A, B, AB or O) and by whether or not their blood is Rh positive or Rh negative.

According to the Australian Red Cross Blood Service, the percentage of blood group frequency in Australia is:

O positive – 40 per cent
O negative – 9 per cent
A positive – 31 per cent
A negative – 7 per cent
B positive – 8 per cent
B negative – 2 per cent
AB positive – 2 per cent
AB negative – 1 per cent.

I'll quote myself from there:

Hate to burst your bubble, but there is no real evidence supporting this. The placebo effect can be a powerful thing, but don't let yourself be fooled by misinformation. I mean, even the wikipedia article is clear that there is no evidence.

Here are some sources addressing the issue:

There's no science supporting this. It's a fad diet that doesn't work and makes no sense.

I think it is great that your health has improved dramatically, but I have to agree with the previous posters. I used to be Vegan and I've seen many people thrive on a whole plant based diet regardless of what type they were.

My Mother is O-, but I'm not sure about my sister. Both of them are also Vegan and if they stuck by what the "eat for your blood type" determines; then their Veganism would be detrimental to their blood type. As for myself I'm B+. I used to suffer from IBS based symptoms a while ago. When I moved to a whole plant based diet the stomach aches disappeared. I don't believe that your blood type necessarily determines what you should or shouldn't eat. There are too many different factors that need to be taken into account for each individual: There is hormones, genetics, metabolic processes and whether or not a person has any intolerances. The book says my Mother and Sister are sensitive to gluten and dairy - Both of them eat pasta and bread a lot (minus the fact that they don't eat dairy obviously).

Just because this new eating lifestyle works for you, doesn't mean there is a correlation necessarily with blood type. If YOU believe it works then by all means. But I would never use those materials for myself. It says also that chicken is bad for me - I eat lean, free range and organic chicken. My body has never had a problem with it, so I'm not sure what it is getting at. When it was eliminated while I was Vegan there wasn't any difference.
