Healthy Diet

The goal of this publication is to promote a healthy diet, improve the health status of the population and prevent chronic non-communicable diseases that are related to unhealthy diet. Diet plays an important role in coronary heart disease, cancers, diabetes mellitus, hypertension, cerebrovascular disease and obesity.

Obesity and Ethnicity

There is no straightforward relationship between obesity and ethnicity, with a complex interplay of factors affecting health in minority ethnic communities in the UK. Apart from Health Survey for England (HSE) data from 2004, there is little nationally representative data on obesity prevalence in adults from minority ethnic groups in the UK. Data are scarce or non-existent for many smaller ethnic groups and only a few qualitative studies have focused on these communities.

Sex differences in obesity rates in poor countries: Evidence from South Africa

Globally, men and women face markedly different risks of obesity. In all but of handful of (primarily Western European) countries, obesity is much more prevalent among women than men. We examine several potential explanations for this phenomenon. We analyze differences between men and women in reports and effects of potential underlying causes of obesity—childhood and adult poverty, depression, and attitudes about obesity.

Obesity Relapse In Women

Obesity and relapse after dieting pose a significant threat to an increasing number of adults in this country. Resistance to treatment and high relapse rates make this problem frustrating for patients and practitioners. There is limited research on relapse causation; research on social and life circumstance factors is uncommon. Given the limitations of existing research, the purpose of this study was to investigate the natural course of obesity relapse.

Communicating Healthy Eating To Adolescents

This study explores perceptions of healthy/unhealthy eating, and perceptions of various socializing agents encouraging healthy eating, amongst Chinese adolescents. A survey was conducted of 152 seven, eighth and ninth grade Hong Kong students. Results showed that respondents frequently ate out with friends and frequently consumed a range of relatively unhealthy food (candies, chips, and soft drinks). They perceived that a balanced diet and eating at a regular time were the most important attributes of healthy eating.

A Diet for Healthy Bones

This lesson will describe osteoporosis and discuss how to maintain healthy bones through all stages of life. Participants will learn about the risk factors for osteoporosis, as well as ways to improve bone health. Emphasis is on including calcium and vitamin D-rich foods as part of a balanced diet.

Healthy Eating and Depression

Most people are aware that a healthy diet is vital in order to reduce the risk of heart disease, diabetes, obesity and other common physical problems. Recent evidence also suggests that good nutrition may be just as important for our mental health and that a number of conditions, including depression, may be infl uenced by dietary factors.

History of Obesity

Obesity has been evident in the human record for over 20 000 years and affected numerous aspects of human life and society (Bray, 2007a; Bray, 2007b). This introductory chapter describes the early history of human obesity, and then reviews how understanding has developed in the basic biology of obesity, its defi nitions and measurement, the complications of the disease, and fi nally its management. Some of the major scientifi c and medical milestones in the history of obesity are shown in Table 1.1.

Research on Obesity and Overweight

Over the past several decades, the prevalence of obesity among adults and children in the United States has increased dramatically and is now reaching epidemic proportions. The prevalence of obesity in adults in the United States was 30.5 percent in 1999-2000. More than twice as many adults (nearly 65percent) were considered to be either overweight or obese. Some 6 million U.S. adults were considered morbidly obese in 2001. In 2002, an estimated 15 percent of all children aged 6 to 19 years were overweight. Obesity is more common in women, but men are more likely to be overweight.


Chemotherapy, or chemical therapy, is one form of treatment that involves giving patients anti-cancer drugs. Most of these drugs are known as cytotoxic drugs, which literally means cell (cyto) killing (toxic).
