Regarding the rhesus comparisons, alcohol caffeine and Vitamin C, D, E and K consumptions were significantly ( p < 0.05) higher in rhesus-positive individuals than their rhesus-negative counterparts. The blood group AB appeared to be the most controlled food intake group. The A group presented statistically significantly ( p < 0.05) greater preferences for cholesterol intake and a higher trend for smoking (25%) habits compared with all the other groups, whereas Group B preferred more fatty foods. Alcohol, caffeine, sugar and Vitamin D consumption were significantly ( p < 0.05) higher in the O group.

Dietary intake was assessed using 3-day food recall and the Food Processor computer program for nutrient analysis.

Additionally, they were divided into two groups according to their rhesus types and their preferences for smoke, too. A total of 329 volunteers were divided into four groups according to their ABO types: Group 1 (A) comprised 141 rBDs Group 2 (B), 65 rBDs Group 3 (O), 96 rBDs and Group 4, 27 rBDs. The aim of our study was to investigate, in healthy regular blood donors (rBDs), the associations of smoke, alcohol, caffeine, vitamin and fat intake with their different blood groups and if ABO groups could be a potential predictor tool for disease prevention. However, the food preferences of individuals with different blood groups have not been examined. The ‘Blood-Type’ diet advises individuals to eat according to their ABO blood group to improve their health and decrease the risk of chronic diseases.
