Are You Eating Right For Your Blood Type?

Posted October 05, 2010 12:00 AM by Jaxy

During a library book sale, I picked up a book that had "Eat Right 4 Your Type" scrawled across the cover and immediately thought it was interesting. Is a diet based upon your blood type justified?

A Little History

Believe it or not, different blood types appeared at different times in history. Blood Type O is the oldest blood type in the world, and is said to have evolved around 40,000 BC when people were mainly meat-eaters. Blood Type A evolved between 25,000 and 15,000 BC when people were becoming farmers and starting to domesticate animals. Blood Type B appeared between 15,000 and 10,000 BC. Lastly, Blood Type AB appeared as an adaptation of Type A and Type B blood. Type AB has only been around for 1,000 years. There have been contradictions to the blood type evolution.

Most people have Blood Type O, while less than 5% of the population has Blood Type AB.

What Can I Eat?

Blood Type O

People with Type O blood are likely to have more acid in their stomach, which means that they can easily digest animal protein. Unfortunately, this also predisposes them to diseases like peptic ulcers, which are a result of too much stomach acid. The book goes on to state that this blood type also usually has low thyroid hormones, so it is recommended to include foods with natural iodine to stimulate the thyroid.

Blood Type A

This blood type does not do well with animal-based proteins and should instead use soy or tofu-based proteins. Blood Type A doesn't produce enough acid in stomach, making it difficult to digest the animal protein. Low stomach acid predisposes persons with this blood type to getting stomach cancer.

Blood Type B

People with Type B blood can tolerate most foods equally well. They tend to have a problem with gluten, but often take dairy very well (as opposed to Type O and A).

Blood Type AB

This blood type combines the best and worst characteristics of Type A and B. With some exceptions, if a food is bad for both Blood Type A and B, it is bad for Type AB. This blood type also does not digest animal protein well, similar to Type A.

So what do you think? Do you think that your blood type should determine what foods you should eat? Does this diet hold any merit?

To read more about this diet and to see my resource, see this link.

Hmm, I suspect that this may be complete hokum of the fad diet variety.
Hasn't science established that peptic ulcers are due to the bacteria Helicobacter pylori?
I reserve the right to be wrong...

I know you were joking but maybe you will find this almost not boring enough to be able to read it:

Cats have only 1 blood group system, the AB system. In this system, there are 3 blood types; A, B and AB. Similar to humans, the blood group antigens are defined by specific carbohydrates on erythrocyte membranes. A N-glycolyl-neuraminic acid determines the A antigen and a N-acetyl-neuraminic acid determines the B antigen with equal amounts of both acids being found on ABCats with blood group B lack a hydroxylase enzyme that converts N-acetyl-erythrocytes.

neuraminic acid to N-glycolyl-neuraminic acid. The blood group antigens are inherited as a simple autosomal trait with A being dominant over B. The inheritance of the AB allele is, as yet, unknown (it is not due to codominance of A and B). The percentage of cats that are A or B positive is breed-dependent

Do you think that your blood type should determine what foods you should eat?

Informative reading but it seems to me more of a guideline on what to avoid.

Thats exactly what I am taking away from this, what not to eat. The older post on Cr4 has a good spreadsheet that categorizes foods, and what is good for whom, though some found it contradictory at times, it appears to simplify things quite well:

Sir Cliff Richard is 70 today & swears by the blood type diet, seems to work for him. I don't have the willpower for it myself.

We need not go by experience (or I would say faith) of others.

You enjoy the food, whaever you like. This enjoyment itsef will take you to 100.

I enjoy, whatever I like. Never done any medical check up and no problem of any sort... I am 58

Our body is so well designed that body itself will make you like what is good for body. If this blood group and the food theory is correct you will see matching between the food you like and the food as per this theory

I agree with you on most of the points. I am 54 and going great. But there are certain areas where the adage : prevention is better than cure applies. For example, a diabetic develops an urge to take more sugar than he used to take when he hadn't developed the problem; likewise a BP patient cannot cut down his salt intake in spite of doctor's advice.

There are some maps of world distribution of blood types in the native inhabitants here:-

On the basis of the blood type distribution data, I think we can conclude the bloodtype diet and its rationale is hokum.

See blood type A for example, very common in several unrelated indigenous groups whose diet was primarily animal protein - recommended tofu??? Man, they must have been a cranky bunch until we finally got global transportation to ship exotic food.... If anything you would expect a dietary-evolution argument to say blood type B, common in Asia, is the tofu-friendly one. It looks like the 'diet' people just made up some facts fiction.

The part of my brain that remembers my blood type has gone missing. Thank goodness, I just listen to my body and eat what it says it wants...

" I just listen to my body and eat what it says it wants..."

That's what I do....... which explains the generous shape I have.
