As a senior lecturer in nutrition, the author is well able to explode many of the myths and, in their place, provides an accessible guide to the science of nutrition. The relationship between diet and health is fully explored and sound, practical advice is given on the effects of dieting and exercise and about the role of fats, fibre, vitamins and other constituents of our daily diet. Later chapters look at topics such as food allergy, coronary heart disease and food additives. Broader issues such as global food supplies and third world problems are also aired to provide a far-ranging perspective on nutrition and society.
