Depression can have disastrous consequences on the British way of life and economy. One in four British adults experience at least one diagnosable mental health problem, such as depression or anxiety, in any one year.

"Our results can now corroborate clinical and epidemiological studies which have revealed associations between an omega-3/omega-6 imbalance and mood disorders,” said researchers Olivier Manzoni and Sophie Layé.
