Cognitive English Grammar offers a wealth of linguistic data and explanations. The didactic quality is guaranteed by the frequent use of definitions and examples, a glossary of the terms used, overviews and chapter summaries, suggestions for further reading, and study questions.

This book is intended primarily for medical students and junior doctors preparing for examinations (regardless of whether they are medical or surgical). In addition we hope that general practitioners and non-ophthalmic consultants who care for patients with eye diseases will find this book invaluable in its simplicity and clarity. We have tried to create a balanced, up to date, practical book. Blackwell’s have supported our need for extensive colour pictures
and diagrams which characterize this ‘visual’ subject.

The current emphasis in preventative medicine encourages healthy lifestyles such as a balanced diet and exercise. In recent years a balanced diet has focused on ensuring functional foods are part of our diet. Functional foods are similar in appearance to conventional foods, but in addition to providing basic nutritional components, have physiological benefits that can reduce the risk of chronic diseases.

 The bioactive components responsible for the health benefits of functional foods are referred to as nutraceuticals. The past decade has witnessed a dramatic expansion in research activities worldwide to identify new functional foods and nutraceuticals. The latter will hopefully enhance the health and wellbeing of an aging population.
