Nutraceuticals are established food components widely consumed as supplements to the diet, either as formulated products or for fortification of foods, particularly functional foods. Over the last two decades there has been a steady growth in research into the possible health benefits. Both the general public and the media have become increasingly interested, and this has coincided with a general interest in health issues. This has resulted in increasing usage of commercially available products, as well as their food sources. It is now well understood that modern pharmaceuticals cannot successfully treat all diseases, coupled with their lack of effectiveness in certain disease states, and the possibility of marked side effects. There is logical use of a number of nutraceuticals which are endogenous nutrients from a range of food sources, as many diseases maybe caused by deficiency states.

In biological systems, the normal processes of oxidation (plus a minor contribution from ionising radiation) produce highly reactive free radicals. These can readily react with and damage other molecules. In some cases the body uses free radicals to destroy foreign or unwanted objects, such as in an infection. However, in the wrong place, the body's own cells may become damaged. Should the damage occur to DNA, the result could be cancer. Antioxidants decrease the damage done to cells by reducing oxidants before they can damage the cell.Virtually all studies of mammals have concluded that a restricted calorie diet extends the lifespan of mammals by as much as 100 percent. This remarkable finding suggests that food is actually more damaging than smoking. As food produces free radicals (oxidants) when metabolised, antioxidant-rich diets are thought to stave off the effects of ageing significantly better than diets lacking in antioxidants. The reduced levels of free radicals, resulting from a reduction in their production by metabolism, is thought to be a major cause of the success of caloric restriction in increasing life span. Antioxidants consist of a group of vitamins including vit

The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people who are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

This book disseminates the cutting-edge knowledge pertaining to nutritional signaling activities in obesity and diabetes, including the regulatory mechanisms and perspectives of nutritional interventions for disease prevention.

Pasteurization, penicillin, Koch's postulates, and gene coding. These discoveries and inventions are vital yet commonplace in modern life, but were radical when first introduced to the public and academia. In this book, the life and times of leading pioneers in microbiology are discussed in vivid detail, focusing on the background of each discovery and the process in which they were developed — sometimes by accident or sheer providence.

A new book in the acclaimed Nutrition Society Textbook Series, Nutrition Research Methodologies addresses the rapidly advancing field of nutrition research. It covers the diverse methodologies required for robust nutritional research to ensure thorough understanding of key concepts, both for students at undergraduate and postgraduate levels and for scientists working in nutrition research. Combining theory with practical application, Nutrition Research Methodologies addresses both traditional research methods and new technologies, and focuses on a range of complex topics, including energy compensation, nutrient-gene interactions and metabolic adaptation. It also considers statistical issues as well as application of data to policy development. Provides the reader with the required scientific basics of nutrition research in the context of a systems and health approach Written specifically to meet the needs of individuals involved in nutrition research Combines the viewpoints of world-leading nutrition experts from academia and research with practical applications Accompanied by a companion website with a range of self-assessment material (www.wiley.com/go/lovegrove/nutritionresearch)
