Eating fruits and vegetables can strongly increase our happiness

fruits and vegetables

In a new research conducted by University of Warwick and University of Queensland, scientists find that eating more fruits and vegetables can substantially increase people’s happiness. The finding will be soon published in American Journal of Public Health.

The goal of the research is explore the benefits of fruits and vegetables to psychological well-being. In the past, it has shown that fruits and vegetables can reduce the risk of cancer and heart disease.

Researchers followed more than 12,000 randomly selected people. These people took part in the Household, Income, and Labor Dynamics in Australia Survey over 2007, 2009, and 2013.

Researchers measured these participants’ food diaries and psychological well-being. The result showed that within two years of an improved diet, people’s psychological well-being was strongly improved.

In particular, happiness benefits were detected for each extra daily portion of fruit and vegetables up to 8 portions per day.

Researchers suggest that eating fruits and vegetables can boost happiness far more quickly than they improve human health.

It can take decades to get the physical-health benefits from eating fruits and vegetables, but it takes a much shorter time to have a better mood via eating fruits and vegetables.

The finding may also be more effective than traditional messages in convincing people to have a healthy diet. There is a psychological payoff now from fruits and vegetables, not just a lower health risk decades later.

In the future, more research will be conducted in this area. For instance, it is possible to link this study to current research into anti-aging that suggests a connection between optimism and carotenoid in the blood.
