Eating fruit and vegetables has this unexpectedly good side-effect

Your five a day portions of fruit and vegetables is not only healthy for your body - it makes you happy too, a new study found.

Levels of happiness increased for each extra portion and peaked at eight a day.

For those who shunned a healthy diet in the past, the equivalent boost in life satisfaction was compared to that felt by going from the dole to landing a job.

And the emotional boost can happen immediately.

The study was 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.
