Eating your blood type

posted by Jason Kottke   Jun 19, 2015

While reading this otherwise excellent article written by US soccer player Christie Rampone, I discovered a type of diet I’d never heard of before, the blood type diet (italics mine).

Age and parenting make me think about longevity. I definitely believe one big reason for my longevity has to do with the dietary and fitness changes I made after being diagnosed with auto-immune conditions after giving birth to my youngest daughter Reece in 2011. For example, I’ve gone gluten-free and have started to eat to my blood-type. Also, a friend introduced me to a natural ingredient called EpiCor to help strengthen my immune system. I have taken EpiCor daily for the past three years and it has become a beneficial part of my daily routine of rest, recovery, working out, eating healthy, and being in airports and hotels more than my own house.

From Wikipedia, an overview of the diet:

The underlying theory of blood type diets is that people with different blood types digest lectins differently, and that if people eat food that is not compatible with their blood type, they will experience many health problems. On the other hand, if a person eats food that is compatible, they will be healthier.

That theory is, in turn, based on an assumption that each blood type represents a different evolutionary heritage. “Based on the ‘Blood-Type’ diet theory, group O is considered the ancestral blood group in humans so their optimal diet should resemble the high animal protein diets typical of the hunter-gatherer era. In contrast, those with group A should thrive on a vegetarian diet as this blood group was believed to have evolved when humans settled down into agrarian societies. Following the same rationale, individuals with blood group B are considered to benefit from consumption of dairy products because this blood group was believed to originate in nomadic tribes. Finally, individuals with an AB blood group are believed to benefit from a diet that is intermediate to those proposed for group A and group B.”

As you might have already guessed, there is no evidence that eating your blood type is beneficial nor do the claims of differing lectin digestion have scientific merit. Homeopathic nonsense.
