View Full Version : Eat Right 4 Your Blood Type

10-13-2005, 12:25 PM
Just curious if anybody has an opinion on the book "East Right 4 Your Blood Type" by Dr. Peter D'Adamo?

It's based on the assumption that your food choices are determined by your blood type (O, A, B or AB), and certain foods are good choices, and others your body cannot tolerate and you should avoid totally.

If I wasn't upset enough, I then find out they also poop on exercise too, saying you should avoid strenuous exercise for type A, B, and AB, and if your type O, then it's "neutral" (neither good or bad). It suggests yoga, meditation, Tai Chi. WHAT - no Spinning??!!

Am I wrong, but I think this is rubbish! My sister-in-law is sold on the idea and is trying to push it on the entire family. My basic reply is "try to eat a clean diet based on all food groups, limit sugars and empty carbs, stick to whole foods."

Jen K. if you're out there, I'd love to know your opinion!

Here , here.
Yet another fad diet based on dodgy, misinterpreted 'science', one persons personal hobby horse.
Whilst one cannot deny food sensitivities, allergies etc, tying such things to blood type sounds like one of those causes looking for, an effect or maybe the other way round, anyhow the existence of one does not prove a causative effect of the other. Besides all of that in prctical terms do you really think that it is possible/desirable to eat such a restrictive diet and remain healthy?Any diet which excludes particular foods (except the NOJUNK diet (TM)) will almost guarantee problems due to missing nutrients.
So you are correct, your nutritional plan is ideal, easy to maintain, inexpensive (relatively) and excludes nothing of any value. Now convince the family how good you feel & look without causing a family feud and you are in business.
Incidentally, I have not tried it for this particular weirdness, but if you Google these things you normally get someone shooting them down in flames in amongst the hucksters selling this rubbish, someone with a science degree is usually worth reading.
Hope this helps.
Keep inquiring.

I don't have a degree in nutrition, but I'll give you my opinion anyway :).

I agree with you -- it's nonsense. Unless you are allergic to a specific food, I believe in eating a variety of foods from all food groups, limiting the less healthy choices and loading up on veggies and whole grains. It's common sense, folks: Calories in need to equal calories out to maintain weight and calories in need to be less than calories out to lose weight. There are many factors that influence someone's ability to change their body weight, but I highly doubt that blood type is one of them.

Tell your sister-in-law to trash the book -- her money would be better spent on a consultation with a good nutritionist and session with a good personal trainer.

Hi Teresa,

I'm here, and gee, what a shock, I have an opinion.;) I agree with you. Even if there is some slight difference in metabolism amongst different blood types (and I wouldn't be surprised if there is, but I would also bet there's not a lot of good science or evidence that really supports it) the human body still does amazingly well with a wide variety of foods. And exercise, for that matter. Some people are going to do better with different balances of macronutrients, but that's far more particular and individual than blood type.

Your family may not have the good sense to listen to you, but that's their problem. All of these various food fads are just ways for folks to try to sell books, because they know that the message of eating a balanced, whole-foods diet is not sexy. And everyone is looking for some way around taking responsibility for what they put into their mouths and how little they move. But long-term, it's the only thing that works. We know there's no magic out there, but that's not a message most folks want to hear (particularly here in America). <sigh>

I'm absolutely no dietician, dietary specialist or food specialist BUT :) .....

I had some skin problems. Got alternative treatment (natural oils from my beautician) and the advice to avoid some food. My skin improved and the problems only come back (just slightly, one or two zits) when I know I've eaten a bit too much of those "bad" foods.
She told me that the bloodtype diet shouldn't be used as a diet, it ISN'T one! Truth is that food has a different influence on your energy levels per blood group. A friend of mine felt really tired all the time, she started paying more attention to her food, following the advice in the blood group diet and her energy levels improved!

On an other note.... in the ancient ways of Ayurveda you have 3 types Water, Fire and Earth. Idealistically all these types are balanced in a person, but normally one is dominant (I myself am very Pitta "fire"). When your dominant type causes physical problems or discomfort you can sooth your dominant type (or better: not encourage) by following certain food patterns. E.g. for me, being so much pitta, eating really spicy food is not good because that will only increase the fire in me.

All in all, I'm with you all the way that these fads are not the way to loose weight (and keep it off!) balanced eating is key! I learned it the "hard" way myself. YoYo-ing for years and years and it wasn't since I cleaned up my eating pattern 3,5 years ago that I am able to keep my weight steady and am happy with it!
