“…Most of the current evidence is correlational, but experimental and micro‐longitudinal research suggests a causal link between FV and well‐being. Two recent intervention studies showed that daily fruit consumption reduced self‐reported anxiety across a 10‐day period (Smith & Rogers, ), and that eating two kiwifruits per day resulted in significant improvements among emotionally vulnerable men in self‐reported ‘vigour,' which included reports of feeling cheerful, energetic, lively, and full of pep (Carr et al ., ). Similar experimental effects have been found for high doses of vitamins B and C, which are found abundantly in FV (Kennedy et al ., ).…”

“…The psychological benefits of FV are less established, but there is evidence that a higher intake is related to psychological well-being (Rooney et al, 2013). People who consume more FV show a lower incidence of depression (Adams & Colner, 2008;Allg€ ower, Wardle, & Steptoe, 2001;Carr, Bozonet, Pullar, & Vissers, 2013;Jacka et al, 2010;Kulkarni, Swinburn, & Utter, 2015;McMartin, Jacka, & Colman, 2013), greater happiness (Blanchflower, Oswald, & Stewart-Brown, 2012), and higher life satisfaction (Blanchflower et al, 2012;Grant, Wardle, & Steptoe, 2009;Lengyel, Tate, & Obirek-Blatz, 2009). For example, in a large sample of over 80,000 British people, a dose-response relationship was found between daily servings of FV and both life satisfaction and happiness.…”

Objectives. Our aim was to determine whether eating fruit and vegetables (FV) is associated with other markers of well-being beyond happiness and life satisfaction.Towards this aim, we tested whether FV consumption is associated with greater eudaemonic well-being -a state of flourishing characterized by feelings of engagement, meaning, and purpose in life. We also tested associations with two eudaemonic behaviours -curiosity and creativity.Design. Daily diary study across 13 days (micro-longitudinal, correlational design).Methods. A sample of 405 young adults (67% women; mean age 19.9 [SD 1.6] years) completed an Internet daily diary for 13 consecutive days. Each day, participants reported on their consumption of fruit, vegetables, sweets, and chips, as well as their eudaemonic well-being, curiosity, creativity, positive affect (PA), and negative affect. Between-person associations were analysed on aggregated data. Within-person associations were analysed using multilevel models controlling for weekday and weekend patterns.Results. Fruit and vegetables consumption predicted greater eudaemonic well-being, curiosity, and creativity at the between-and within-person levels. Young adults who ate more FV reported higher average eudaemonic well-being, more intense feelings of curiosity, and greater creativity compared with young adults who ate less FV. On days when young adults ate more FV, they reported greater eudaemonic well-being, curiosity, and creativity compared with days when they ate less FV. FV consumption also predicted higher PA, which mostly did not account for the associations between FV and the other well-being variables. Few unhealthy foods (sweets, chips) were related to well-being except that consumption of sweets was associated with greater curiosity and PA at the within-person level. Lagged data analyses showed no carry-over effects of FV consumption onto next-day well-being (or vice versa).Conclusions. Although these patterns are strictly correlational, this study provides the first evidence that FV consumption may be related to a broader range of well-being states that signal human flourishing in early adulthood. Statement of contributionWhat is already known on this subject?There is growing evidence that a diet rich in fruits and vegetables (FV) is related to greater happiness, life satisfaction, and positive affect. These associations are not entirely explained by

“…Por otro lado, la deficiencia de vitamina C se asocia con síntomas de depresión, fatiga e irritabilidad (35), y la suplementación con polivitamínicos ha demostrado mejorar el funcionamiento mental y el estado de ánimo de individuos diagnosticados de estrés (36), y también en los aparentemente sanos (37). Esto sugiere que las alteraciones del ánimo se pueden deber a deficiencias nutricionales, incluso subclínicas (38).…”

“…Recientemente, el kiwi ha sido objeto de estudio como alimento con potencial efecto positivo en el estado de ánimo en individuos que tengan un consumo insuficiente de frutas y verduras y que tengan insuficiencia de vitamina C (< 50 mmol/L en plasma) (38). Estos resultados sugieren que dos kiwis proporcionan la cantidad óptima de vitamina C (unos 200 mg) (38).…”

Both the Green ® kiwifruit (Actinidia deliciosa) and the Sungold ® one (A. chinensis) stand out among other commonly consumed fruits for their nutritional composition. They are fruits exceptionally rich in vitamin C, since green kiwi fruit have twice and Sungold ® have three times the same amount of the vitamin of strawberries or oranges. Kiwifruit is very rich in vitamins E, K, folates, carotenoids, potassium, fi ber and other phytochemicals. Regular consumption of kiwifruit, in the context of a balanced diet, has proven to have benefi cial effects on immune function and antioxidant defense; also in the gastrointestinal function, improving protein digestion and constipation; and in the upper respiratory tract, preventing infections and improving their symptoms. Finally, regular consumption of kiwifruit has been associated with improvements in mood. Most of these benefi ts may be due not only to the high content of vitamin C of the kiwifruit, but also to other nutrients and phytochemicals that work synergistically in the food matrix. The results of the studies suggest that the daily consumption of kiwifruit can be an effective strategy for health promotion and prevention of numerous diseases. ResumenLos kiwis, tanto la variedad verde (Green ® ) (Actinidia deliciosa) como la de color amarillo (Sungold ® ) (A. chinensis), destacan entre las frutas de consumo habitual por su composición nutricional. Son excepcionalmente ricos en vitamina C, ya que los kiwis verdes duplican la cantidad que tienen las fresas o naranjas, y el kiwi de color amarillo incluso la triplica. Además, los kiwis tienen un elevado contenido en vitaminas E, K, folatos, carotenoides, potasio, fi bra y otros fi toquímicos, que proporcionan no solo benefi cios nutricionales, sino también sanitarios. El consumo regular de kiwi en el contexto de una dieta equilibrada tiene efectos benefi ciosos sobre la función inmune y defensa antioxidante; en la función gastrointestinal, mejorando la digestión proteica y el estreñimiento; y en el tracto respiratorio superior, ayudando en la prevención de infecciones y mejorando su sintomatología. Por último, el consumo habitual de kiwi se ha asociado a mejoras del estado de ánimo. La mayoría de estos benefi cios pueden deberse al elevado contenido de vitamina C del kiwi, pero también a los otros nutrientes y fi toquímicos que actúan de forma sinérgica en la matriz alimentaria. Los resultados de los estudios realizados hasta ahora sugieren que el consumo diario de kiwi puede ser una estrategia efectiva para la promoción de la salud y prevención de numerosas enfermedades.
