You can eat your way to happiness

Apart from reducing the risk of cancer and heart attacks, consuming up to eight portions of more fruit and vegetables a day can substantially increase people's happiness levels in life, finds a new study.
"Eating fruit and vegetables apparently boosts our happiness far more quickly than it improves human health," said Andrew Oswald, professor at the University of Warwick in London.
The findings showed happiness increased incrementally for each extra daily portion of fruit and vegetables up to eight portions per day. People who changed from almost no fruit and vegetables to eight portions of a day showed an increase in life satisfaction. Usually people's motivation to eat healthy food is weakened by the fact that these were predictive of alterations in happiness and satisfaction later in life. "However, well-being improvements from increased consumption of fruit and vegetables are closer to immediate," Oswald added.
Large positive psychological benefits were found within two years of an improved diet consisting of more fruit and vegetables, the researchers said. "There is a psychological payoff now from fruit and vegetables -- not just a lower health risk decades later," noted Redzo Mujcic, researcher at University of Queensland in Australia.
