Dietary Tips by Blood Type

Health tips and blood types

As the world grapples to respond to the novel coronavirus pandemic, we’re all looking for ways to get through it. Some of us are trying to figure out how we’ll survive, whether physically or financially. And others among us are seeking ways to contribute to the rescue effort. With a zillion worries and ideas racing through my mind, I decided last week to go in and donate a pint of blood.

While the blood slowly dripped out of my arm and into the bag, I got to thinking about my blood type. I’m pretty sure it’s A+ (the same as my high school GPA), but I was hoping they could confirm that. (Confirmation will actually come in the mail in a couple weeks.)

So then I started wondering, what good will it do to know my blood type? I figured, it must make some sort of difference as far as the kinds of foods that my body will crave or abhor. It turns out I’m not the first one to have this idea.

The Blood Type Diet

In 1996 naturopath Peter J. D’Adamo published a book entitled  “Eat Right for Your Type”, in which he described what he considered to be the best dietary recommendations for each blood type. The book gained great attention, even becoming a best-seller, although its overall premise remains somewhat controversial. In any case, people are always interested in new diets, so let’s have a look.

People with type O blood should maintain a high protein diet, with plenty of red meat, poultry and fish, as well as a good mix of whole vegetables. They should try and minimize grains, legumes and dairy. This is somewhat similar to the Paleo diet. Just think of O as in Omnivore. Type O people should also do vigorous aerobic exercises like running or cycling.

People with type A blood should be the best candidates for vegetarianism, with a diet rich in fruits, vegetables, beans and whole grains. You can think of A for Agriculture. Type A people, according to the diet, should do yoga or tai chi for their exercise.

People with type B blood are supposed to eat a diverse diet of vegetables, meats and low-fat dairy. Foods to avoid include chicken, corn, lentils, tomatoes and peanuts, according to D’Adamo. Maybe B stands for Balanced?

People with type AB blood should eat a lot of dairy, seafood, tofu, lamb, fish, grains, fruit, and vegetables. Because they tend to have less stomach acid, D’Adamo say that type AB people should try to avoid or minimize caffeine, alcohol, and cured meats. Corn and chicken should also be avoided for weight loss.

Conclusions

While there is little or no scientific evidence to support the efficacy of the blood type diet, it’s certainly an interesting idea to consider. The theory claims that O was the original human blood type, dating back to the era of hunters and gathers. Type A supposedly developed around the time that our ancestors began adopting the agrarian lifestyle. And Type B corresponds to the time of herding nomads, when people started consuming greater quantities of dairy. However, this timeline is also the subject of some debate.
