We all know that a diet high in fat, sugar and processed food is bad for our waistlines.
But according to a new book, it is also making us depressed.

Drew Ramsey, a clinical psychiatrist at Columbia University, and health writer Tyler Graham say that eating the right food is 'the foundation of good mental health'.
