The Effect of Healthy Nutrition and Functional Foods Education Based on the Health Promotion Model for Individuals With Type 2 Diabetes on Healthy Lifestyle Behaviors and Self-Efficacy in Diabetes: Randomized Controlled Study

Non-communicable diseases (NCDs) are defined by the World Health Organization (WHO) as "slowly progressing and long-lasting diseases, health problems that require continuous care due to the combination of genetic, physiological, environmental, and behavioral factors." (WHO 2023). One of these health issues, Diabetes Mellitus (DM), is one of the chronic and universal health problems affecting many people worldwide (Ministry of Health 2021). When diabetes is not controlled, many acute or chronic complications arise that significantly affect both the individual and society (Üstündağ and Dayapoğlu, 2021). As a result of the complications caused by diabetes, various organ and function losses occur in the individual. As a result, the individual's lifespan and quality of life are negatively affected, and social and economic losses that impact the entire society also occur. (Olgun ve ark. 2017). Therefore, healthy lifestyle behaviors influence minimizing the risk of diabetes and controlling the diabetes that has developed. These include healthy eating, regular medication use, regular exercise, weight maintenance, stress management, quitting smoking/alcohol, and patient education. Coordinating all of these ensures successful diabetes management (Üren and Karabulutlu 2018). Functional foods encompass certain minerals, fatty acids, dietary fibers (such as vegetables, fruits, whole grains, and legumes), antioxidants, or prebiotics that contain biologically active extracts and have beneficial effects on life. (Granato ve ark 2020). For example, foods that contain bioactive substances such as dietary fiber, polyphenols, saponins, and peptides, and have a low glycemic index, help diabetic patients in regulating their blood sugar levels. (Kazeem \& Davies, 2016). Under the guise of nutrition education, natural functional foods that balance blood sugar in our daily lives can create awareness among individuals with type 2 diabetes, making diabetes management easier alongside medicati
