BSE631 TermPaper Vidur Kumar (Y8560) Obesity and cancer – linked to what level? Abstract –
Obesity today is a major health issue in populations across the globe. The lifestyle changes occurring in the 21st century have resulted in ‘abundance’ of all things – including that of visceral fat in all age‐groups across the globe. There are many health‐conditions already linked with obesity – such as diabetes, high‐blood‐pressure, congestive heart‐failure, reproductive complications, etc – but, could being obese make one susceptible to cancer? Or possibly make for a worse cancer prognosis? These issues are addressed in this report, with references to many studies performed at the population level, and at the molecular level – attempting to link cancer progression (prostrate cancer), severity and occurrence, with symptoms of obesity – such as visceral fat, adipokine levels, etc. Focusing primarily on the adipokine levels in obese (cancer/non‐cancer) patients, in vitro tumour culture studies and data from prostrate/breast cancer patients – this report aims to hint at a possible mechanism which underlies cancer progression on the basis of the data from above studies and explain how obesity as a condition, fits in the mechanism of tumor progression.

Introduction to obesity –
The first aspect regarding obesity is the quantification of the physical condition called ‘obese’. For the purpose of this report (and for most of the studies referred to) – computer tomography generated measurements in the order of ~300cm2 area in the central abdominal regions (i.e. – of visceral fat), is defined as the condition for obesity. Alternatively, other quantifications, such as Wasit‐to‐Hip ratios, Body Mass Index, etc are also used to define or correlate specific aspects of body structure to the condition of being obese or its related metabolic syndromes.

Processed Foods in the American Diet

...foods, Americans had no choice but to eat whole, natural, raw foods. As our technology advanced, our need for food to not spoil grew as quickly. Though as preservatives, additives, and processed foods increased in our diet, the integrity of food declined. With our new abilities to package and preserve food, food came to have more and more preservatives and contain fewer nutrients. Processed foods should usually be avoided because, over time, they contribute to obesity and can lead to disease; in order to help avoid these problems, the public needs to be educated on the negative effects of most processed foods and they need to be made more aware of affordable healthy alternatives. Obesity is a problem in the United States. According to the Center for Disease Control, 35.7% of adults are considered to be obese. The CDC also reports that obesity-related diseases or conditions are the second leading cause of death; some of these include: type 2 diabetes, heart disease, stroke, and even certain cancers (CDC, Para. 2).

Breast Cancer

...your life to decrease your modifiable risk factors for this disease Breast cancer is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from ducts are known as ductal carcinomas, while those originating from lobules are known as lobular carcinomas. Breast cancer occurs in humans and other mammals. The primary risk factors for breast cancer are female sex and older age.[19] Other potential risk factors include: genetics,[20] lack of childbearing or lack of breastfeeding,[21] higher levels of certain hormones,[22][23] certain dietary patterns, and obesity. Recent studies have indicated that exposure to light pollution is a risk factor for the development of breast cancer.[24] Smoking tobacco appears to increase the risk of breast cancer, with the greater the amount smoked and the earlier in life that smoking began, the higher the risk.[25] In those who are long-term smokers, the risk is increased 35% to 50%.[25] A lack of physical activity has been linked to ~10% of cases.[26] The association between breast feeding and breast cancer has not been clearly determined; some studies have found support for an association while others have not.[27] In the 1980s, the abortion–breast cancer hypothesis posited that induced abortion increased the risk of developing breast cancer.[28] This hypothesis was the subject of extensive scientific inquiry, which concluded...

Obesity

...CHAPTER 1 INTRODUCTION Definition Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems. People are considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight in kilograms by the square of the person's height in metres, exceeds 30 kg/m2. Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders, medications or psychiatric illness. Evidence to support the view that some obese people eat little yet gain weight due to a slow metabolism is limited; on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass. Dieting and physical exercise are the mainstays of treatment for obesity. Diet quality can be improved by reducing the consumption of energy-dense foods such as those high in fat and sugars, and by increasing the intake of dietary fiber. Anti-obesity drugs may be taken to reduce appetite or inhibit fat absorption together with a suitable diet. If diet, exercise and medication are...

Sugar Consumption in America

...Introduction The number of American people who are obese has increased over the years. This complex condition has affected almost all ages with children obesity being on the rise. Obesity can be linked to the onset of some diseases such as diabetes, hypertension and some heart diseases that have increased the risk of death and reduction of an individual’s health. The answers that we seek are concerned with sugars’ role in the development of obesity and the emergence of related diseases. It is important to consider an individual’s genes when determining vulnerability to obesity but what doctors mostly emphasize is on food intake. As the socioeconomic levels of most Americans rise, diets are increasingly having a higher proportion of sugars while work is shifting into a less physical nature. The high proportion of sugars in the American diet has a direct relationship to obesity and other related illnesses. Is sugar related to obesity and medical disorders associated in the American society? In order to become fully aware of the link between sugars and diabetes, we have to look at the features and nature of sugar. Sugar is a generalized name for a crystalline carbohydrate that is simple, edible and has a sweet flavor. The main types of sugar are sucrose, lactose, fructose and glucose.

They have been subjected to excessive modern processing and are full of man-made ingredients, rendering them so unrecognisable from their original form that your body simply doesn't know what to do with them. Regularly eating these foods creates a toxic build-up that wreaks havoc on your health, as an impressive body of scientific studies show. Truth be told, there are foods that, for the sake of health and longevity, we should not be eating at all, or, at the very least, eating only rarely. As our consumption of these foods has increased over the years, so have the incidences of obesity, diabetes and heart disease, three of the most deadly diseases worldwide. Three white devils Among the nutrition-savvy, these are said to be the root of all evil when it comes to health. While these foods may seem relatively benign compared to the rest of the list, they are most dangerous when eaten regularly - and for many people, that is the case.
