Bridging Science and Lifestyle: A Feasibility Study for Developing a Novel Functional Food to Support Well-Being

This feasibility study investigates the relationship between functional food consumption and mental well-being, focusing on natural foods traditionally linked to mental health benefits. This research also examines consumer preferences to identify key characteristics that novel functional foods designed to enhance mental well-being should possess. Additionally, this study lays the groundwork for a clinical trial exploring the effects of a novel functional food on mental health and well-being. Data were collected through an online bilingual survey (Greek/English) from 362 participants across Greece and Cyprus, using an adapted Functional Food Frequency Questionnaire (FFFQ) featuring 30 foods with documented effects on cognitive function and mood regulation. The survey included validated scales measuring mental well-being, health-related quality of life (HRQoL), sleep quality, and food choice motives, along with demographic and anthropometric data. Analysis revealed significant associations between functional food consumption and mental health outcomes, particularly in HRQoL, sleep quality, and body mass index (BMI). Most functional foods consumed were natural and aligned with the Mediterranean dietary pattern, such as fruits, vegetables, nuts, herbal infusions, and honey, all demonstrating positive effects on mental and physical health. Consumer preferences showed a strong inclination toward functional foods that balance sensory appeal with health benefits, including milk-based and plant-based beverages, protein bars, and granola bars. Ingredients like St. John’s wort and Greek mountain tea were identified as potentially beneficial for mental well-being, consistent with their established efficacy in psychological health. A significant majority of participants (66.9%) expressed interest in participating in clinical trials, highlighting the need for further research into the efficacy of functional food components. This study provides a foundation for future clinical trials examining the impact of novel functional food formulations on mental and physical health, addressing the growing consumer demand for products that enhance psychological resilience and well-being.
