Berries, Apples, and Citrus Linked to Greater Happiness and Optimism

A recent study in Clinical Nutrition examined the bidirectional associations between dietary flavonoid intake and psychological well-being (PWB) and discusses supporting strategies that integrate dietary and mental health interventions to promote long-term health.

Psychological Well-Being and Diet

Psychological well-being (PWB) is a multidimensional construct encompassing happiness, optimism, and a sense of purpose, and has been increasingly recognised as a central determinant of overall health. High levels of PWB are associated not only with improved quality of life but also with a reduced risk of chronic diseases, such as cardiovascular disease and diabetes, as well as lower mortality and greater healthspan. These associations are believed to be partially mediated by healthier lifestyle behaviours, such as regular physical activity, balanced nutrition, and avoidance of harmful habits.
