New research led by the University of Kent and University of Reading has found that fruit and vegetable consumption as well as exercise can increase levels of happiness.
While the link between lifestyle and well being has been previously documented and often used in public health campaigns to encourage healthier diets and exercise, new findings published by the Journal of Happiness Studies show that there is also a positive causation from lifestyle to life satisfaction.
This research is the first of its kind to unravel the causation of how happiness, the consumption of fruit and vegetables and exercising are related, rather than generalizing a correlation. The researchers, Dr Adelina Gschwandtner (Kent’s School of Economics), Dr Sarah Jewell and Professor Uma Kambhampati (both from the University of Reading’s School of Economics), used an instrumental variable approach to filter out any effect from happiness to lifestyle. It showed that it is rather the consumption of fruit and vegetables and exercising that makes people happy and not the other way round.
