Lettuce be happy: A longitudinal UK study on the relationship between fruit and vegetable consumption and well-being.
Due to the scarcity of studies using this method, Ocean et al. (2019) decided to adopt the panel data analytical technique to investigate the relationship between increased consumption of fruits and vegetables and psychological well-being. The same individuals were questioned a total of 3 times between 2010 and 2017 as part of the UK Household Longitudinal Survey. The fixed-effects regression estimates using a reversed form of GHQ-12 demonstrated that as the number and frequency of fruit and vegetable intake increased, so did the well-being of the participant. The results suggest that the relationship is robust and the subjective aspect of the study should be negligible. After comparing age with fruit and vegetable consumption, a hump-based relationship was found. [NPID: mood, happiness, vegetables, well-being, fruit]
