demonstrated that people having tobacco-chewing habits with blood group A were at a 1.46-times greater risk of developing oral cancer, compared with those of blood groups B, AB and O. In the past, studies to demonstrate the association of smoking with ABO blood groups were conducted, without significant results. In the literature, a few studies have demonstrated the analysis of dietary habits as well as smoking to investigate the possible association with the blood group system. Additionally, the ABO blood system has been verified to be linked with the severity of some infectious diseases such as malaria for the B group and COVID-19 for the A group. Additionally, the blood type O presents a connection with an increased incidence of cholera, plague and tuberculosis infections, whereas the blood type A seems to be linked with an increased incidence of Pseudomonas aeruginosa infection. Moreover, AB individuals were found to be linked with an increased incidence of smallpox, E. On the other hand, research on the ABO group system proposed an association between ABO blood groups and a variety of diseases such as hepatitis, thrombotic disorders, metabolic and cardiovascular diseases, cognitive disorders and circulatory diseases. demonstrated that, although adhering to some blood-type diets may reduce cardiometabolic risk factors, these links are independent of an individual’s ABO group. They participate in the production of specific antibodies, the proliferation of lymphocytes, and T cell differentiation. Vitamins, and especially Vitamins A and D, have a crucial effect on the regulation of immune responses and have a protective role in inflammation and autoimmunity. Caffeine is a nutrient that can be found in many beverages and plays an important role in health because of its interference in Vitamin B and essential mineral absorption moreover, in low doses, besides producing an increase in mental energy and attention, and elevated mood, it also has antioxidant properties.

The most common food preferences comprise caffeine, alcohol, fruits, and vegetables containing vitamins and fats. This theory considers our ancestral dietary habits and suggested that adherence to diets specific to one’s blood type can reduce the risk of cardiovascular disease and improve health generally.

Since the publication of the book “ Eat Right for Your Type” by D’Adamo, there has been a series of debates for and against the correlation of an individual’s ABO blood group, eating habits and health. In conclusion, in the present study, statistically significant correlations of the ABO and rhesus system with some dietary parameters were found, indicating a consequent influence of these preferences on the progression of different diseases.ĪBO blood grouping is one of the first genetic variations recognized in humans and has since been linked to several health conditions. For the non-smoker group, compared with the smokers, a higher consumption of Vitamin D and fibers was found. 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.
