Broad beans could be the cure to Britain’s blues, says Cambridge research scientist

Sustainable and nutritious, fava beans are being hailed by Nadia Mohd-Radzman as vital for the UK's mental health

Nadia Mohd-Radzman is a botanist on a mission. The Cambridge University researcher wants the UK to recognise the wonders of a crop that she believes could transform the nation's health. Hence her campaigning - for the broad bean.

Vicia faba has a host of special properties, she argues. It is rich in protein, fibre and iron, for example. More importantly, it contains chemicals that are linked to lasting improvements in the moods and emotions in those who consume them, Mohd-Radzman told the Observer.
