There’s been a lot of buzz about the link between blood type, diet, and exercise. Most scientists reject the connection; however it does bear some consideration. For example, how are some people able to exist on a vegetarian diet, while others need a high protein, meat-rich diet? Why is it that a meat-rich diet makes some feel energetic, while others feel lethargic and bloated? In my own experience, I have found a vegetarian diet almost impossible to follow. Despite taking iron/vitamin B supplements, I ultimately become anemic. It’s only after I reinstate my meat diet that I feel stronger and more energetic – I even notice a change in my skin tone and hair condition. I personally don’t fare very well eating a lot of carbohydrates, as they don’t satisfy my hunger properly and leave me feeling very lethargic. This is directly in line with what I have read about blood type O, thus giving the blood type diet some merit. It did take a few years and a lot of experimenting with my food that I came to the realization – blood type should dictate what we eat and plays a vital role in our lifestyle.
Blood type O
Blood type O is the oldest and most common of all the blood types. According to Dr. D’Adamo, author of ‘Eat Right For Your Blood Type’, O’s digest meat easily, as the digestive tract retains memory of ancient times. They are also more susceptible to ulcers due to greater levels of stomach acid. They will find the digestion of meat easier than type A’s, for example. O’s were the hunters and meat eaters of our ancestors.
Blood type A
People with A blood type have high levels of an enzyme known as intestinal disaccharide. This enzyme makes meat digestion difficult, making them fare better on a carb-rich, vegetarian diet. I have a good friend who is blood type A. She is vegetarian, has been for most of her life, and never suffers any health problems, or anemia. According to Dr D’Adamo, type A’s were the more settled and less warlike of our ancestors. They were less nomadic, stayed in one place and became farmers. As such type A’s evolved to be more suited to a diet high in grains and vegetables. They have sensitive immune systems and are found in high numbers in Scandinavia and Central Europe.
Blood type B
B’s have a digestive tract that fares well with dairy products. This may well explain why some people more likely to be lactose intolerant. B’s are also the hardiest of the blood types – they have good immune systems and are usually quite successful in fighting off chronic disease. Of all the blood types, B’s are the most adaptable to change and are found mostly in Northern India and Central Asia.
AB’s, the most biologically complex, are able to eat foods and follow exercise regimens that suit both A & B blood types. They are the most recently evolved and are very rare. The “modern” blood type AB has a sensitive digestive tract and should avoid chicken, beef, and pork but enjoy seafood, tofu, dairy, and most produce.
According to Dr A’damo’s book, our blood contains unique antigen markers, which differentiate the blood types, acting as an indicator of alien foods in the body. Our blood type supposedly dictates our personality type; propensity towards disease; even the type of exercise we should be doing. Naturally there are skeptics out there who challenge the connection between our blood and what we eat, as there is no scientific basis for these claims. But each of us is unique, our blood containing a unique cellular profile, so it would make sense that a “one size fits all” lifestyle isn’t feasible, wouldn’t it?
Certain countries such as Japan take the blood type issue so seriously, that in job interviews you may be asked your blood type so prospective employers can gain insight into your personality!
So what are the foods most suited to your individual blood type? Let’s take a look below:
Blood Group O – Meat eaters
O’s do best on a high protein, low-carb diet. Foods you should include in your diet are:
Potatoes (can cause inflammation of the joints in this blood type)
Favourable exercise for O’s include aerobic exercises such as running, weight-lifting, swimming. Anything vigorous.
Blood Group A – Vegetarian
Favourable exercise for A’s: Anything calming; yoga, Tai Chi.
Blood Group B – Omnivore
Of all the blood groups, B’s have the least restrictions on what they can eat. They should however, take care to avoid processed foods, and chicken. Thanks to their nomadic ancestors, they are a hardy bunch and should fight off disease quiet well.
Favourable exercise for B’s: Tennis, brisk walking, aerobics
Blood Group AB – Mixed and balanced
The rarest blood type, AB’s do best with a combination of meat, fish, and dairy products. As they encompass the attributes of both A and B blood types, they should have plenty of variety in their diets. They should avoid red meat and corn
Favourable exercise for AB’s: Yoga, stretching, Tai Chi
Naturally we have to bear in mind that if we eliminate certain foods from our diet, we need to be sure to eat alternative foods with the same nutritional value. For example, those considering dropping diary products from their eating plan would do well to supplement with foods such as nuts and broccoli, which contain calcium. In addition to food alternatives, one has to look at the ethical issue. If you are an O blood type who believes eating meat is morally wrong, then you have a duty to yourself to find the right alternatives, or at least to source your meat as ethically as you can.
If there is still some doubt about eating right for your blood type and you need some proof, then there is no better way than to experience it firsthand. I can honestly say that the diet and exercise suggestions put forth by Dr. A’damo for my blood type (O) are directly in line with what works for me, and make me look and feel my best. If you are interested in knowing more, I highly recommend Dr A’damo’s book, and perhaps a month-long experiment eating the foods he recommends for your blood type to see how you feel.
NOTE: It is always advisable to see your GP prior to changing your diet and eating plan.
