The Eat Right 4 Your Type Diet comes to us from Naturopathic physician Peter D’Adamo who claims that your blood type (A, B, O or AB) is critical in determining your nutritional health. The contents of your blood will go a long way towards determining what food you should eat and how healthy overall you will be. Certain medical conditions afflict those with certain blood types and not others. Dr. D’Adamo even goes so far as to claim that certain types of exercise should be paired up with particular blood types for maximum benefit.
Dr. D’Adamo believes that the sugar binding proteins in foods, called lectins, will react differently according to our different blood types. It is therefore critical to choose the correct foods according to our blood types if we want to improve our overall health and avoid weight problems.
For example, if you are blood type A then you should eliminate most meat, dairy and citrus. For type B blood, you want to reduce your consumption of chicken and pork. Type O should focus on a low carbohydrate, high protein diet. For those with AB blood you need to limit your red meat and certain fruits.
In his book, Dr. D’Adamo lists which foods are good, bad and neutral for each blood type. He also has a section on supplements and even which type of exercise you should adopt. For someone with blood type A they should practice yoga or Tai Chi to improve their posture, breathing and stress levels. It is hard to see how this wouldn’t help anyone no matter what their blood type.
This brings us to the trouble with this diet. There is no independent scientific proof of Dr. D’Adamo’s claims. Namely, that blood type correlates to specific health problems and therefore what types of food you should consume to limit those problems, including being overweight. There is no consideration of the nurture side of the “nature versus nurture” debate. Specifically that what we do can affect our health just as much as what type of blood we are born with.
Your personal habits and behavior will contribute to your overall health. Someone who does not smoke, overeat and does exercise regularly will be fitter and less overweight than someone who does smoke, overeats and does no exercise, no matter what blood type they are. This is common sense and has been scientifically proven repeatedly over many years of research. With type O blood (low carb, high protein diet) if you are a vegetarian you food choices will be severely limited, and you may be nutritionally challenged on this diet.
This book is well written and easy to understand with clearly defined food lists of what to avoid and what is good. The diets (no matter which blood type) are all generally healthy so there is no harm in trying them. However, it is important to note that there is no scientific basis for the theory behind the ‘Eat Right For Your Type’ diet. The book does not address one’s personal habits and how they directly relate to your weight loss goals. However if you still want to try this plan you might also want to purchase Catherine Whitney’s book called “Cook Right For Your Type” which has lots of recipes and meal plans for each blood type.
