Assignment Title: Case Study Obesity

Nutrition for Health and Disease - Case Study: Obesity
The prevalence of obesity in England has more than tripled in the last 25 years. (Department of Health 2012) largely due to dramatic changes in dietary/lifestyle trends with attributing factors such increasing use of transportation, sedentary lifestyles, wider food choices, availability of cheap convenience foods in times of economic decline and also powerful food advertising through media coverage and the increase in fast food restaurants and larger portions; all of these factors have led to a dramatic rise in obesity in the UK, leaving the government with a major public health dilemma due to its correlation with serious chronic diseases. The term 'obesity' is used to describe a situation where a person is carrying too much body fat for their height and sex. An individual is considered to be obese if they have a body mass index (BMI) of 30 or more. (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person's weight in kilograms divided by the square of his height in meters (kg/m2). The WHO definition is: a BMI greater than or equal to 25 is overweight, a BMI greater than or equal to 30 is obesity. According to the Department of Health being obese or overweight brings significant risks at a range of different points throughout life. The health risks for adults are stark. Their statistics show for example, that compared with a healthy weight man, an obese man is five times more likely to develop type 2 diabetes, three times more likely to develop cancer of the colon, more than two and a half times more likely to develop high blood pressure which is a major risk factor for stroke and heart disease, (Department of Health) reduced quality of life, and can even lead to premature death. Obesity affects people of all ages as diagram 1 below evidences,

    Does Traffic Light Labelling Have the Potential to Reduce Obesity Rates in the Uk

    The past twenty years has seen obesity rates in the UK increase dramatically (HSCIC, 2013), resulting in the reduction and prevention of obesity becoming a major public health priority. The World Health Organisation (WHO) (2013) defines obesity as ‘abnormal or excessive fat accumulation that may impair health’ and body max index (BMI) is commonly used in the classification of overweight and obesity. A BMI of 25-29 makes an individual overweight and a BMI of 30 or above is classified as obese (WHO, 2013). A concerning statistic showed that in 2011 a mere 34% of men and 39% of women were defined as being a healthy weight; with a BMI between 18.5 and 25 (NHS, 2013), compared with rates in 1993 where 44% of men and 50% of women fell into this category (HSCIC, 2013). The Health Survey for England in 2010 (NHS: The Information Centre, 2012) stated that 62.8% of adults and 30.3% of children are overweight or obese, with 26.1% of these adults and 16% of these children being obese. Obesity is a major risk factor for the development of diseases such as type 2 diabetes, cardiovascular disease, stroke, some cancers and may be detrimental to certain social aspects of life, such as finding work and can affect mental health (Department of Health, 2013). As a result of these obesity trends in 2011 it was found that approximately half of obese men and women suffered from high blood pressure and there were nearly 12,000 admissions to hospital for obesity related illnesses in 2011-2012, which had increased more than 11 times compared with figures in 2001-2002 (NHS, 2013). In 2007, the Foresight Report (Department of Health, 2007) predicted that without action being taken 60% men, 50% and 25% children would be obese by 2050. Alongside these serious implications for health and quality of life, obesity is a growing burden on…

    Food Intake Paper

    Food intake is something that everyone should take very seriously in their daily lives. Food intake is regulated by the complex interaction of psychological and physiological events associated with ingestion. While the energy content of foods has an important role in determining the amount eaten, a number of other properties of foods also may be important. These include palatability, macronutrient composition, and form of the food for example solid vs. liquid, how it is prepared, and its energy density.…

    To what extent is obesity a public health issue

    We are, according to most public health authorities, in the midst of a pandemic of “globesity”, (global obesity) a term coined by the World Health Organisation in 2001. The question remains whether globesity is a disease itself, a symptom of underlying physiological or psychological illnesses or even a sign of social excess and therefore not a disease in the medical sense at all. This ‘obesity epidemic’ seems to be increasing and many countries have started looking into ways of preventing or slowing down this epidemic by introducing initiatives. For example, in October 2007, the UK Government launched its ‘Tackling Obesities’ project and reported that most adults in the UK were already overweight, and predicted that by 2050 around 60% of men and 50% of women would be clinically obese. It has also been suggested that obesity must have an association with long-term health prospects. The connection between obesity and the risk of ill health has been recognised in Western cultures for at least two thousand years and it first became a noticeable health issue in the USA and recognised as a chronic disease in 1985 by the USA’s National Institutes of Health, although many people disagree with this classification. While it is acknowledged as a public health threat, many prefer to see obesity as a risk factor for other diseases rather than a disease in its own right. It is associations between obesity and serious diseases such as diabetes and cardiovascular diseases that have lead obesity to be known as a major killer. Obesity has been defined as having an excess accumulation of body fat (Prentice and Jebb, 2003). It is the excess body fat that creates the most serious health problems.The National Audit Office (1) clearly highlighted the damaging impact obesity has on health: both the impact on the individual - for example, on…
