This eleventh edition of the Manual of Nutrition is published at a time when there has never been a greater public interest in the relationship between food and health. It is also a period of unprecedented efforts to tackle food-related public health problems such as cardiovascular disease, and the ever-increasing incidence of over weight and obesity in all age groups of the population. There is particular concern about saturated fat, salt and sugar intakes, but the science of nutrition is much broader than that. This manual therefore describes the major nutrients, their roles in the body, the foods that provide them, and the way in which these foods are digested so that the nutrients can be utilised by the body. A new feature for this edition is coverage of the safety aspects of vitamin and mineral intakes from dietary supplements. Reflecting current emphasis in dietary advice, new values for children's target salt intakes are included as are practical aids to achieving a healthy diet such as portion sizes for fruit and vegetables. Fully illustrated, with tables to aid further understanding, the Manual continues to be a source of reference to a wide range of students, teachers and health professionals as well as interested members of the public as it was when the first edition was produced sixty years ago.
