Blood type diet debunked

01/03/17

Last week a study was published indicating we should be eating 10 pieces of fruit or vegetables a day instead of five, to reduce the risk of cardiovascular disease, cancer and all-cause mortality. In the Belgian press, the opinion of nutritionist Hilde Demurie was asked. She promotes a diet based on blood type, following Dr. Peter D’Adamo and his book Eat right for your blood type. This diet suggests a specific diet based on your blood type, e.g. people with blood type A should follow a vegetarian diet to get healthier and lose weight. In 2013, we published a systematic review showing that there is absolutely no evidence to support this diet. In addition, in 2014 a study was published indicating that adherence to certain ‘Blood-Type’ diets is associated with favorable effects on some cardiometabolic risk factors, but these associations were independent of an individual’s ABO genotype, so the findings do not support the ‘Blood-Type’ diet hypothesis. Our systematic review was used as one of the main references in the YouTube video Blood type diet debunked by Nutritionfacts.org. Recently, a second YouTube video was posted debunking the blood type diet, also referring to our systematic review.
Conclusion: do not take “expert opinion” for granted, always be critical with information!
