Dr. Lustig’s main focus throughout the presentation was the effects of fructose on the epidemic of obesity. He explains how we as a society place so much stress on fat intake and calories in versus calories out that we tend to neglect what is actually in our food. With much research, it has been determined that fructose does, in turn have an effect on the obesity epidemic. Throughout the lecture, many examples from this research show our biochemical response to our modern diets and are used to explain Dr. Lustig’s point of fructose poisoning. He begins to construct his point by describing how our caloric intake or food intake has consistently gone up over the years and fat intake has gone down, but obesity has continued on a dramatic incline.
I chose to watch “Weight of the Nation”, because the title itself was appealing. I made the assumption that the documentary would provide information on weight throughout the United States. I wanted to get a holistic view on the obesity epidemic that we are struggling with. This documentary was well informative; obesity is a factor of genetics, environmental and behaviors. Granted some may people may have a harder time losing weight because of their genes, at the same token they shouldn’t use that as an excuse.
As we know Overweight and obesity are defined as abnormal droth of cell or excessive fat gathering that may harm health , The obesity is measured by Body mass index (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). For adults, the World Health Organization defines overweight and obesity as follows: The increase weight is a body mass index greater than or equal to 25 Obesity is a BMI greater than or equal to 30. BMI provides the most beneficial measure at the population level of overweight and obesity as is the case for men and women for all ages of adults. However, it should be considered as raw evidence because it may not correspond to the same degree of fat in different individuals.
Polymorphisms in various genes controlling appetite and metabolism predispose individuals to obesity when sufficient calories are present. Social practices and policies also may either be beneficial or detrimental to children's physical health. These social factors may include the emphasis of schools on physical activity, prevalence of and access to parks, bike paths, and sidewalks and also the prices of healthy and unhealthy foods. Advertising of unhealthy foods correlates with childhood obesity rates. In some nations advertising of unhealthy food is illegal or very limited on children’s television channels.
Consequently, some of the expense to the community regarding how obesity occurs causing medical complications of diabetes, heart attacks, and high blood pressure which produce expense on the economy. Preventing obesity educating individuals and families through the proper eating practices to prevent childhood and adult obesity. The study of sociology regarding obesity could use the theory of structural functionalism that analyzes obesity in the United States. However, millions of Americans remain obese and overweight which affect the whole body through fatty tissue that causes many conditions like high blood pressure, heart disease, diabetes, stroke and many types of cancer. Nevertheless, obesity in the United States leads to indirect costs of higher medical and psychological costs of around
This is manifested by the statuettes taken during the Paleolithic period of plump women. There are different social factors related to obesity for example discrimination and low self-esteem. It is an important measure in determining the rate of exposure to serious health issues such as heart attack and obesity. The higher the body mass in comparison with the height, the higher the BMI. Individuals with a BMI less than 18.5kg/m2 are considered underweight.
It may be true that a person’s lifestyle might not be the main reason being overweight. however, studies had proven that the gene can only cause people to gain an extra 1 or 2 kilos where people who are obese usually carry an extra 50 kilos which are mainly caused by overeating and a poor lifestyle. That is why the fat gene should not be taken into consideration when looking for the reason of obesity In short, the main cause for obesity and poor health is the lack of self-care and an unhealthy lifestyle. Overall, people who are active most of the day have a less chance of developing weight problems or become obese. Also, people who carefully look into what they are eating usually are thinner and healthier.
RDI values suggest that 460-920mg should be consumed per day. The diet provides on average 1295.14mg per day meaning slightly excessive amounts of sodium are being consumed, however it is well beneath the upper limit of 2300mg per day. Thiamin is required in the diet to assist in the conversion of carbohydrates to energy, muscle contraction, and conduction of nerve signals (MedlinePlus, 2015). RDI values for thiamin suggest that 1.2mg of thiamin should be consumed per day. This diet provides an average of 0.79mg per day, less than 50% of the recommended amount [refer to Graph 1].
The rise in obesity and its comorbidities among young is multifactorial in cause, including increased access to foods high in fats, added sugars and calories, larger portion sizes and a sedentary lifestyle. The diversity of these contributors to childhood obesity has made it difficult to design simple, achievable, public health solutions (Australian Health survey, 2011). Studies have been conducted to identify strategies to combat obesity among youth; yet much remains to be understood. But, the mechanisms responsible for the growing occurrence of childhood overweight or obesity are not entirely implicit, unhealthy dietary behaviours have a vital role (WHO,
Some of the more burning issues that we’ve identified are: the lack of exercise, less time to prepare healthy meals for oneself and family, obesity, increased stress levels and less time for rest and relaxation. Unhealthy lifestyle is a dissipated personal modus aperandai which may be characteristed by one or more of the following substance abuse, ego, alcohol, drug use etc. (Mc Graw Hill-2002). To fully understand what contributes towards an unhealthy lifestyle we first need to know what it is. Unhealthy eating and little exercise has become the norm in our society.
Obesity is a major risk factor for this disease and with lifestyle changes it can be prevented, delayed, or reversed. Healthy People 2020 consider obesity as an epidemic in the United States. It recognizes the role obesity plays in so many other chronic diseases and therefore has made healthy weight maintenance an objective for Americans to reach. One way to organize different sources of health disparities and health problems as well as intervention strategies is by the use of the Social Ecological Model. This model is a proposed way to help identify resources that will facilitate access to health.
So what exactly is the problem? Well, the USDA food desert locator (3) shows that ten percent of America is classified as a food desert. Households all across the country don’t have access to fresh and healthy food causing them to resort to unhealthy cheaper food like fast food or food someone could get from a convenience store. Food deserts can impact the health of our nation. Especially when it comes to obesity, because studies have shown that having greater number of convenience stores are linked to having higher obesity.
As the frequency of obesity decreases, the medical bills will also dwindle. In 2008, the Center for Disease Control stated that an average of $147 billion dollars was spent on overweight individuals. Instead of feeding money to the obese, funds can assist an actual epidemic, not just a self-inflicted issue. Doctors claim eating healthy, automatically results in healthier habits such as an increase in exercise. Instead of counting pizza slices, consumers will begin counting miles, releasing endorphins that make them tolerable.
In any case, now we should investigate the larger picture, which is that in ten years that is a total gain of thirty pounds. This weight gain can lead to type two diabetes which is associated with being overweight and numerous health issues emerge, for example, heart attack, stroke and kidney disease just to name a few. There are so many negative side consequences for obesity and essentially, we need to commit to fighting this epidemic. I must say it is disturbing that this is the first generation of children that will live a shorter life than their parents will. I think one serious issue is that food quality has decreased in a major way because corporations want to maximize profit.
