Blood Type Diet Proved False

Dr. Peter D’Adamo opened up a new avenue of enquiry and research about dieting and ways to live healthier with his book ‘Eat Right 4 Your Type’ in which he suggested each blood type should follow a different diet in order to maximise health and, as a side effect, weight loss. A study suggests, however, that there is no scientific evidence to support his theory.
The diets, based on the point in evolution from when each blood type emerged, follow the general idea behind the diets that certain cultures would have eaten at the time. For example, the Type A’s of the world emerged as early human societies began to cultivate the land and farm. Therefore, Dr. D’Adamo suggests a loosely vegetarian diet to “supercharge the immune system”.
However, researchers of the University of Toronto had a study published in PLOS ONE which debunked the theory put forward, and sold to thousands, by Dr. D’Adamo. Upon examining 1,455 followers of D’Adamo’s diet, they found there was “no evidence to support the blood type theory”.
This isn’t to say, however, that all of D’Adamo’s theory is bad. Apparently, certain health benefits were discovered in followers of all blood types, showing that the four diets included in ‘Eat Right 4 Your Type’ are all beneficial diets.
But, as Dr. Ahmed El-Sohemy of the research team said, the health benefits of the participants have “nothing to do with their blood type and has everything to do with their ability to stick to a sensible vegetarian or low-carbohydrate diet.”
So the blood type theory doesn’t magically solve all dieting issues, but has created four individual diets, each with its own health benefits. In the end, it is the ability to stick to the diets and the old ‘eat less, exercise more’ mantra, that really is the magic key.
