A huge component of this class was nutrition; I have learned that nutrition should be a top priority in everyone lives. One’s nutrition plays a critical role in their body composition and overall health. There are several components that go into maintaining a healthy diet, and the trends and popular diets are ever-changing, constants are rare when it comes to nutrition. One constant that seems to remain the same, regardless of any new technological advances or scientific studies, is our need of fats, carbohydrates (sugar), and proteins in our diet. This exposition will discuss the 3 macronutrients in detail, emphasizing their function in the body and dietary sources for the macronutrient. First thing first, let’s discuss one of my favorite macronutrients, carbohydrates otherwise known as carbs. Carbs which is essentially sugar comes from starch, fruit, vegetables, milk, meat, sports drinks and any other food that has sugar in it (Hall, 2017). For a good while, carbs were portrayed as unhealthy and as something that should be avoided in our daily diet, with books, magazines, and popular diets all correlating with the trend to paint …show more content…
Proteins can be thought of as the tissue builders in our body (Hall, 2017), and vegetarians can still get their daily recommended amount of protein, proving that a vegetarian diet is not a major risk to one’s health. Protein can come from poultry, eggs, fish, nuts, and seeds (2017). Some major functions of protein in our body include structural formation, acid/base and electrolyte balance, enzyme function, energy, immune function, and transport function (Hall, 2017). The wide variety of jobs a protein host in the body is actually pretty extensive and obviously variable. Not only is protein function in the body variable, its sources and recommended daily intake also have a high degree of variability, which a great plus that benefits
Michael Pollan, an American author, journalist, activist, and professor of journalism at the UC Berkeley Graduate School of Journalism (Michael Pollan), writes in his book In Defense of Food, the dangers of nutritionism and how to escape the Western diet and subsequently most of the chronic diseases the diet imparts. In the chapter “Nutritionism Defined” Pollan defines the term nutritionism. Pollan’s main assertion being how the ideology of nutritionism defines food as the sum of its nutrients, and from this viewpoint Pollan goes on to write how nutritionism divides food into two categories, with each macronutrient divided against each other as either bad or good nutrients, in a bid for focus of our food fears and enthusiasms. Finally, Pollan concludes that with the relentless focus nutritionism places on nutrients and their interplay distinctions between foods become irrelevant and abandoned.
In the year 2010, the documentary Fat, Sick, and Nearly Dead was released. In the film, Australian native Joe Cross has realized that his health is worsening very fast. So Cross finally decides that he will turn his life around by taking an extreme diet that will deprive him of macronutrients for 60 days. Macronutrients are nutrients found in foods other than fruits and vegetables. Micronutrients are those nutrients found in fruits and vegetables. Micronutrients provide minerals such as Vitamin A, Iodine, Iron, Folate, and Zinc. While the body does not need these in large amounts, they are essential to the body because they help develop disease prevention and promote well-being. Micronutrients are important to include
Nutritionism and Today’s Diet Nutritionism is the ideology that the nutritional value of a food is the sum of all its individual nutrients, vitamins, and other components. In the book, “In Defense of Food” by Michael Pollan, he critiques scientists and government recommendations about their nutritional advice. Pollan presents a strong case pointing out the many flaws and problems that have risen over the years of following scientific studies and government related warnings on the proper amount of nutrients needed for a healthy diet. Pollan’s main point is introducing science into our food system has had more of a negative impact than a positive one, we should go back to eating more of a traditional diet. I believe food science has given us
Provide muscle energy, fuel for the nerve system, the fat metabolism and protect the protein to been used as energy
The girl once in high school struggling with her weight has now learned the value of a low carb diet and what it can do for her body and her health. “The low carb diet was most beneficial for lowering triglycerides, which are the main fat- carrying particle in the bloodstream” (The Nutrition Source). Therefore, targeting the fats in one’s body is one of the most important aspects of the low carb diet. If one can lower the triglycerides in their system this will guarantee that the diet has more of a chance of working correctly ensuring weight loss. When trying to accomplish this task The Nutrition Source suggests that it is good to try to include some fruits, vegetables, and whole grains essential vitamins, minerals, and phytonutrients. Although some might be quick to analyze the access of ease to this diet, it is easily attainable if one has a plan set up to how they will go about starting a low carb
The question comes up again; “How is your diet?” Jessica revisited her diet analysis from the first week of class. She noticed that some things have changed and some things, unfortunately, have not changed. She knew that some things would not change because of the hectic and busy semester and summer she had ahead of her but the things that did change surprised her. This class did some good for her, but she still needs some work on her diet and nutrition.
There are nine amino acids that are considered “essential” for health, which we must obtain from our diets since our bodies cannot make them on their own. Some of the roles that amino acids/proteins have include helping to form and maintain muscle mass, providing energy for our cells and brain, helping store away energy for later use in fat stores, making your heart beat, and helping build the foundation of vital organs, including your heart, lungs and even your DNA, and supporting growth/development. Because of its ties to lean muscle mass and satiety in terms of controlling your appetite, protein is especially important as you age.
Nutrition and physical activity are important aspects as they improve health and reduce chronic diseases. In June of this year my family physician placed me on a doctor assisted weight loss program that enabled me to eat my favorite foods but in appropriate proportions and in heathier ways. The best part about Supertracker is that it gives me wonderful tools to support me in understanding and meeting my goals. Once I created a profile through Supertracker I was provided a personal plan to follow including the amount of grains, vegetables, fruits, and protein I needed to be successful. For three consecutive days, I entered my food and activity intake into Supertracker and was able to analyze the excesses and deficiencies
Nutritionism is an ideology that believes that the nutrients in foods are the key to understanding them. Nutritionism believers are so focused on the nutrients that food contains that they forget about all other aspects of food. The problem is that consumers rely on packaging to tell them what nutrients a food provides, since nutrients cannot be obviously seen, and they rely on science to tell us what nutrients are good and which are “evil”.
For years, I have been eating what I want. Food choices are a significant factor that affects our health. What we like or crave, often, is the determining variable in what we eat. Finding the right balance of food choices is the key factor in improving our health benefits. Choosing nutrient-dense foods will provide more nutritional value than foods that are found to be low in nutrient density. Making the right choices in foods, however, is extremely difficult. Often, I find myself enthralled in the latest fad, not considering the subtext of the foods I am eating, such as nutrients, vitamins, healthy fats and unhealthy fats, cholesterol and minerals. The diet project underlined a three-day food entry intake that provided a dietary analysis report
Diets high in plant protein, such as the vegetarian diet, are linked with many health benefits. Studies suggest vegetarians tend to have a lower body weight, lower cholesterol, lower risk of diabetes, lower blood pressure levels. (21) (18) They also have a lower risk of stroke, cancer and death from heart disease than non-vegetarians (15) (16).
2. Orogastric: This route is used when NG is contraindicated, and to prevent sinusitis. It is tolerated well by the sedated patients but not in awake patients.
Moderation is vital in all aspects of life and is necessary for overall health, including with one’s food intake. Protein is one of the many important nutrient building blocks that is necessary for proper growth and good health. However, eating excessive amounts of any nutrient or inadequate amounts, can cause various health concerns. Scientists have been able to estimate the amount of nutrients that the body requires. However, the amount of any particular nutrient varies from person to person, depending on your “age, sex, general health status, physical activity level, and use of medications and drugs” (Schiff 2013). It is also important to remember that consuming the required amount of nutrients that meets your dietary guidelines does not
Proteins (macronutrient), which are found in animal products, nuts and beans, they help to build new cells, maintain tissue and synthesis new proteins essential for performing basic bodily functions. Proteins are in abundance in the human body and are present in the outer and inner membranes of all living cells (Dummies, 2018). Proteins are essential for building new cells, maintaining tissue and helping new proteins needed for basic bodily function (
I chose to have the same meal for breakfast, lunch and dinner for three days, not in a row, of course. So day one, two and three will look the same; it is roughly what I consume on a regular basis, I really didn’t have to alter my meals much at all, only to make sure I had the same meals each day.
