This book focuses on the three most important aspects of ageing research: nutrition, physical exercise and epigenetics. The contributors discuss ways that age-related epigenetic imprints such as DNA methylation and histone acetylation are modified by these two interventions. The emphasis on epigenetics helps to illuminate the underlying mechanisms of anti-ageing interventions, as ageing and disease are predominately epigenetic phenomena. Among the highlights are chapter-length discussion of such topics as:  how anti-inflammatory action of calorie restriction underlies the retardation of ageing and age-related diseases (Chapter 3); epigenetic modification of gene expression by exercise (Chapter 5); the role of functional foods and their bioactive components in bone health (Chapter 8); and an account of the first decade of a study of calorie restriction in nonhuman primates, conducted by the National Institute on Ageing.
