Fruit and Vegetable Intake Predicts Positive Affect
- 1.1k Downloads
Prior research suggests that fruit and vegetable intake predicts psychological well-being (WB) when controlled for demographic variables such as age, income and education. Using multiple-item measures and including additional diet and health variables as covariates, the current study assessed self-reported well-being in the past week and daily fruit and vegetable consumption over the past 4 weeks for 1270 university students. Mean positive affect increased linearly as a function of number of daily servings of fruits and vegetables; the pattern of this relationship did not differ significantly for males and females. This association remained statistically significant after controlling for demographic variables (age, sex, and parent education levels); other diet variables (consumption of sugar containing beverages, coffee or tea, and fat); and other health behaviors (exercise, sleep quality and smoking). Life satisfaction and negative affect were not significantly related to fruit and vegetable consumption. Analysis of single-item measures similar to those used in past large scale surveys yielded similar results. Possible reasons for the association of fruits and vegetable consumption with well-being are discussed.
