Fruit and veg give you the feel-good factor
New research suggests up to 8-a-day can make you happier
University of Warwick

COVENTRY, UK - July 2016: University of Warwick research indicates that eating more fruit and vegetables can substantially increase people's later happiness levels.

Published in the prestigious American Journal of Public Health, the study is one of the first major scientific attempts to explore psychological well-being beyond the traditional finding that fruit and vegetables can reduce risk of cancer and heart attacks.

Happiness benefits were detected for each extra daily portion of fruit and vegetables up to 8 portions per day.

The researchers concluded that people who changed from almost no fruit and veg to eight portions of fruit and veg a day would experience an increase in life satisfaction equivalent to moving from unemployment to employment. The well-being improvements occurred within 24 months.

The study followed more than 12,000 randomly selected people. These subjects kept food diaries and had their psychological well-being measured. The authors found large positive psychological benefits within two years of an improved diet.

Professor Andrew Oswald said: "Eating fruit and vegetables apparently boosts our happiness far more quickly than it improves human health. People's motivation to eat healthy food is weakened by the fact that physical-health benefits, such as protecting against cancer, accrue decades later. However, well-being improvements from increased consumption of fruit and vegetables are closer to immediate."

The authors found that alterations in fruit and vegetable intake were predictive of later alterations in happiness and satisfaction with life. They took into account many other influences, including changes in people's incomes and life circumstances.
