James Colquhoun and Laurentine ten Bosch direct this documentary exploring the importance of nutrition and the health benefits of a good diet. At the heart of the documentary is a comparison of the effectiveness of commonly used medical treatments with the less invasive and expensive 'nutritional therapy' advocated by the film-makers. Professionals including Andrew Saul, Charlotte Gerson and Dr Dan Rogers offer their thoughts on whether diet can tackle diseases such as cancer, depression and heart disease effectively.
