The ‘Blood-Type’ diet advises individuals to eat according to their ABO blood group to optimize health without the support of science evidence. The objective of this study was to determine whether consumption of a diet in accordance with an individual’s ABO genotype is associated with various biomarkers of cardiometabolic health. Study subjects (n=1,455) were participants of
the Toronto Nutrigenomics and Health study. Dietary intake was assessed using a one-month, 196-item food frequency questionnaire and a diet score was calculated to determine relative adherence to each of the four blood type diets. ABO blood group was determined by genotyping rs8176719 and rs8176746 in the ABO gene. The results show that adherence to the Type-A, Type-AB, and Type-O diets were associated with favourable profile of certain cardiometabolic risk factors (P<0.05); however, these dietary effects were not dependent on someone’s ABO blood group. Therefore, the findings do not support the “Blood-Type” diet hypothesis
