Statistical analysis, including regression modeling, was employed to explore the relationships between perception, health outcomes, frequency, and duration of consumption. Participants perceived green tea and matcha as beneficial for weight management, cardiovascular health, and, to a lesser extent, diabetes control. While these perceptions align with existing literature on the health benefits of polyphenols and caffeine found in green tea and matcha, there were notable disparities in consumption patterns, with many participants reporting infrequent consumption. This discrepancy between public perception and scientific evidence underscores the need for balanced health communication strategies. Furthermore, the study highlights the importance of considering individual variations in response to these beverages, as evidenced by reported side effects like irregular heartbeats.

By offering complete amino acid profiles, omega-3 fatty acids, and antimicrobial peptides, insect proteins may help address nutritional gaps and positively influence oral tissue regeneration and microbiome balance. Their low-carbohydrate content also reduces substrate availability for cariogenic bacteria, making them a valuable alternative to starch- or sugar-rich diets. We justify this dietary transition in light of present nutritional deficiencies and demonstrate how insect proteins can register within a holistic approach to global health (<em>One Health</em>) and the <em>Planetary Health Diet</em>, supporting sustainability and improving overall health.
