Abstract: Background and Objective: The Mediterranean diet is a diet based on the consumption of fruits, vegetables, whole grains and seafood and has reported positive effects on cardiovascular diseases and chronic diseases such as type 2 diabetes and obesity. In addition, breakfast is the most important of the main meals and is also associated with many health effects. In this study, we aimed to evaluate the nutrients and nutritional elements consumed by individuals considering their adherence to the Mediterranean diet. Materials and Methods: The study was conducted with healthy volunteers who regularly ate breakfast and who were between 18 and 64 years of age. Data on Mediterranean diet compliance and breakfast consumption were obtained by a questionnaire. According to the scale of compliance with the Mediterranean diet, ≤5 points was considered low, 6-9 points was moderate and ≥10 points was high. Data were analyzed using the One-Way ANOVA test. Results: A total of 400 adult individuals with a mean age of 34±13.5 years participated in the study. The majority (60.3%) had moderate adherence to the Mediterranean diet. Those who showed high adherence to the Mediterranean diet consumed more soup and oilseeds at breakfast than participants with other compliance levels (p<0.001). Moreover, herbal tea consumption at breakfast was the lowest among those with low compliance (p<0.001). The energy and macronutrient intakes at breakfast did not differ according to the level of compliance with the Mediterranean diet (p>0.05). Conclusion: It was determined that more than half of the participants had a moderate level of compliance with the Mediterranean diet. The data obtained as a result of the study contribute to the literature in terms of interpreting the adherence of the participants to the Mediterranean diet in the context of their nutrient preferences at breakfast. More studies with a larger sample size should be conducted.
