Nutrition, Health and Disease: A Lifespan Approach

 

DESCRIPTION:

 

Nutrition, Health and Disease

In this newly revised third edition of Nutrition, Health and Disease, prominent researcher and Professor of Human Nutrition Simon Langley-Evans delivers an easy-to-read and student-friendly textbook on the changing demands for nutrients made by the body throughout the human lifespan.

Thorough introductions to lifespan nutrition, maternal nutrition prior to conception, pregnancy, and the relationship between fetal nutrition and disease later in life

Practical discussions of lactation and infant feeding, nutrition during childhood, nutrition during adolescence, and nutrition in the adult years

Detailed examination of contemporary evidence of the relationship between diet, body weight, and the major nutrition-related diseases: cancer, heart disease and diabetes

Exploration of vegetarian, vegan, and other alternative diets, as well as dieting for weight loss in adults, gender and nutrition, macro- and micronutrients, and a background on nutritional epidemiology

Access to an updated student companion website with additional resources

Perfect for nutrition and dietetics students, as well as newly qualified nutrition and dietetics professionals, this foundational textbook will also earn a place on the bookshelves of other healthcare students and professionals who seek a one-stop reference on the impact that nutrition has on health and disease.
