Nutrition Concepts and Controversies


Nutrition can be defined as the process of absorbing nutrients from food and processing them in the body for growth, replacement of tissues, and maintenance of good health. Historically, women have been responsible for cooking and providing meals for their families. Often, that food was grown in the family garden or local community. The women may not have had much formal education, but they seemed to know, almost instinctively, what was good for their families. Life was less complex earlier in time, and fewer food choices existed. The evolution of technology and modern farming techniques has caused a great deal of change in the quality of our food. Water, soil, and air pollution are depleting our soil of vitamins essential for good health, and an increase in the amounts of food additives, chemicals, sugar, and unhealthy fats in our foods has contributed to the increase in chronic diseases present in society. Therefore, it is critical that people learn as much as they can about their nutritional needs and the connection between their diet and their health. This paper will review of basic nutrition. This paper discussed nutrients in foods and nutrients diet constituents. Further, it will cover Nutrients and the Human Genome along with emphasis on diseases associated with poor nutrition. In last, the paper will address Nutritional Challenges within Families. There are many good introductory nutrition texts and books, where the basics of food, nutrition, and health as can be found, however, this paper is drawn heavily from the textbook by Frances Sizer and Ellie Whitney entitled Nutrition: Concepts and Controversies 11th Edition.

A Lifetime of Nourishment

...Why is nutrition important? What impact does it have on our physical and mental health? Nutrition is important because it nourishes and energizes the body. Without it the body can not function properly and can have a long lasting effect your health. “Poor nutrition habits can be a behavioral health issues, because nutrition and diet affect how you feel, look, think and act.” (Ajmera, 2011). Dieting without the proper nutrition and lack of exercising causes obesity which in turn can lead into mental problems such as depression. For me personally, I tend to eat when I am bored or depressed. Most people decided to take out their frustration on food instead of hitting the gym. When we eat healthy, we feel energize and have confident in ourselves. What are the six classes of nutrients? How do they individually and collectively help us to maintain our health status? There are six types of nutrients including water, carbohydrate, fat, protein, vitamins, and minerals. Water is the most important nutrient that needs to be consummated daily so we can function properly. Each type of nutrients has its benefits on its own but can produce better quality when combine with others. Carbohydrates, fats and proteins provide the energy we used on a daily basis. Vitamins and minerals are used by our organs to function properly and effectively. Someone consumes carbohydrates but does not take the proper vitamins; they will have energy but can have a hard time digesting food. What are the......

How Religion Is Impacted by Science Extending the Lifespan of a Human

...Table of Contents Abstract 2 Introduction 3 The Impact Medical Technology has on Religion 6 How Religion Will Respond Given Their Principles and Doctrines 7 The anti-aging therapies are raising controversies in science and religion 12 Conclusion 13 References 14   Abstract People figured out early on that living longer would be beneficial if they had the chance to do so. They would be able to spend more time with their friends and family, have more time in life to accomplish things they set out to do, and they could simply enjoy more of what life has to offer. This is a great mindset for anyone to have since life is a beautiful thing and worth living. With all of the advanced medical technology on this specific subject and the new findings that are constantly being done to prolong the human lifespan, we start to enter into the area of what is ethically right and wrong and wonder how much is too much? There are many different forms of medical treatment that can save someone’s life. This will vary from medicine to surgery and many things in between. Not everyone will agree on some of the techniques used, but most people understand why someone would want to save their life. Since people will try to save their own lives if they are dying, many scientists believe that there is no difference in trying to extend a life through medicine, or trying to create a life from another person through a cloning system. This is where the tables turn from helping mankind,...

Diabetes Awareness: Signs, Symptoms and, Prevention and Nutrition

...Robert Chin HUN1201 Principles of Nutrition 04/20/2014 Diabetes Awareness: Signs, Symptoms and, Prevention and Nutrition As a very young child, I grew up watching my mom struggle with her diet every day. She suffered from diabetes and was forced to keep a constant watch over every single morsel of food she put in her mouth. Over the years began to understand much more about the complexities of my mother’s disease and how vital it was for her to maintain a healthy and active lifestyle. As the disease progressed, my mother was forced to introduce now and more invasive methods to manage her disorder, including insulin shots twice daily. Despite all of her efforts to keep her disease in control, my mother lost her battle at the horrifyingly young age of 47.Watching her fight so bravely against sometimes that she eventually would have no control over was a tremendous inspiration to me. My mother’s journey is the reason that I have decided to come up with a healthy balanced diet for an individual who is diagnosed with diabetes. My hope is that I can educate diabetes about their disease and maybe give them more precious time with their loved ones that I had with mine. Diabetes mellitus, more commonly called simply diabetes, is a group of metabolic diseases. People afflicted with this disease have high blood sugar, either because their body does not produce enough insulin, or because the body's cells do not respond to the insulin that......

“Do We Need More Regulation on Food? Why or Why Not?”

...“Do we need more regulation on food? Why or why not?” Food regulation is a developing concept that constantly requires attention and iteration in order to minimize food safety and health risk and best manage and communicate these risks. Food Regulation is the production, processing, distribution, retail, packaging and labeling of food items and constituents that are governed by a mass of laws, regulation, codes of practice and guidance. Similarly, food safety is a scientific discipline describing handling, preparation and storage of food to prevent foodborne illness. Though similar, the differentiating factor is that food safety informs food regulations. Consider food safety as the assessment and food regulation as the management and communication domains to reduce risks. The current piece will evaluate the scope of food regulation and look at how it has been developing over the years. The current piece highlights the mechanism of food regulation, explores major players and shares several differentiated case studies to further navigate food regulation problems and implementations. Over the course of history, food regulations, both proposed and implemented, have represented the primary concerns that arose during a certain period of time. Food regulation has been enforced since 300 BCE and since then, one of the most important food regulations was enacted in 1906 through the Pure Food and Drugs Act. The Pure Food and Drugs act prohibited interstate......

Global Proverty

...Global Poverty If I was to describe world poverty I will have to quote Mother Teresa “We think sometimes that poverty is only being hungry, naked and homeless. The poverty of being unwanted, unloved and uncared for is the greatest poverty of them all”. I believe this quote says it all. It really shows what poverty is about. It made me realize that people that are poor don’t just need to be feed and sheltered, but also need to be loved. While some of us just think of what we could do to better our homes and cars many people living in absolute poverty just want clean water, food, shelter, and their health. It makes you want to step back and look at life in different perspective and want to better the world we live in. Poverty is the most essential problem we have to today and has been a continuous problem since the beginning of time. No matter what the income, unemployment or overall prosperity level is, there will always be people who are homeless and hungry around the world. I recall myself saying when I was younger to my peers that I was poor and grew up with little because we had a one bedroom house and I had to wear passed down clothing from my older sibling, but after traveling to various countries I have recognized that I was never deprived of anything. I had all my meals and plenty of clothes and shelter in which some people wish they had. Poverty doesn’t discriminate billions of people lack basic resources including food, water, education and......

Why Statistics Needed in Education Especially in Research

...Why statistics is needed in Education, especially in Research An Assignment for M. Phil Education (Research) Supervisor: Dr. Khalid Saleem Sb. Muhammad Yasin Khan   Why statistics is needed in Education, especially in Research What is statistics? Statistics is a range of procedures for gathering, organising, analysing and presenting quantitative data. ‘Data’ is the term for facts that have been obtained and subsequently recorded, and, for statisticians, ‘data’ usually refers to quantitative data that are numbers In very broad terms, statistics can be divided into two branches – descriptive and inferential statistics. 1. Descriptive statistics is concerned with quantitative data and the methods for describing them. (‘Data’ (facts) is the plural of ‘datum’ (a fact), and therefore always needs a plural verb.)This branch of statistics is the one that you will already be familiar with because descriptive statistics are used in everyday life in areas such as government, healthcare, business, and sport. 2. Inferential (analytical) statistics makes inferences about populations (entire groups of people or firms) by analysing data gathered from samples (smaller subsets of the entire group), and deals with methods that enable a conclusion to be drawn from these data. (An inference is an assumption, supposition, deduction or possibility.) Inferential statistics starts with a hypothesis (a statement of, or a conjecture about, the......

...Week 2 Reading summaries Claude Fischler “Food, Self and Identity” (1988) * Food goes deeper than being a source of nutrition, it is central to our individual identity given that we are constructed, biologically, psychologically and socially by the food we choose to incorporate into our lives. * Omnivore’s paradox: One of the fundamental components of our identity as omnivores is that we have the autonomy, freedom and adaptability to consume a wide range of food. However this liberty also implies dependence and constraint. Omnivores cannot obtain all the nutrients it needs from one food alone and omnivores must also avoid harmful foods. * The principle of incorporation dictates that food and cuisine are a central component of the sense of collective belonging. * Disgust is a socially constructed biological safeguard. The psychology of eating behavior reveals that children have the tendency to accept only a limited range of food they are familiar with. This gives us insight into our natural instinct as humans to put new exotic foods through thorough examination before we consume it. * Because of how complex identifying a food can be based on its cultural origins, the culinary system provides a pre-fabricated matrix where one can identify a food by understanding its place in the world. * In today’s society as food is becoming more processed and integrated through globalization our cultural and physiological identity through food is......

Should Congress Pass the Farm, Nutrition, and Bioenergy Act of 2007?

...Intro establishes significance without taking sides: Every five years, Congress introduces a multi-billion dollar bill that affects all Americans. This legislation has come to be known as the Farm bill, and this year’s is quite possibly the most scrutinized, criticized, and important farm bill that has ever been introduced. So, the question arises: “Why is the farm bill such a controversial issue?” Dan Imhoff answers, “If you eat, pay taxes, care about the nutritional values of school lunches, worry about the plight of biodiversity or the loss of farmland and shrinking open space, you have a personal stake in the tens of billions of dollars annually committed to agricultural and food policies” (18). Now the controversy and social problems—as seen by each side—are introduced. The Farm bill is responsible for funding numerous food related programs, such as subsidies, the food stamp program, and also the farmer’s safety net, to name just a few. Where this money goes and how it is spent reflects what the United States values, and what it is defining as a social problem. Some supporters of this bill maintain that this bill provides financial security not only to agriculturalists but also to consumers as well. They believe that this bill promotes an increased emphasis on of conservation, and that it also encourages efforts to explore the merits of bioenergy. The value placed on conservation, cleaner, more efficient energy sources, and the financial protection of American......
