Nutrition:
Food Classification: Food is anything edible, solid, semi-solid, or liquid when swallowed, digested and assimilated in the body. It provides us with energy, repairs body tissue, builds new cells and tissues, protects the body from disease and regulates body processes. Food can be classified as macronutrients or micronutrients. Macronutrients consist of Carbohydrates, Proteins and Fats. Micronutrients consist of Vitamins and Minerals.
Macro Nutrients: There are three macronutrients. Carbohydrates, Proteins and Fats.
Functions: Carbohydrates usually come from plant sources. They are the fuel for exercise and work. When it is digested it is converted into blood glucose or is stored as glycogen in liver. Excess is stored as fat. There

They consist Carbon, Hydrogen and Oxygen. Fats are composed of a glyceride and 3 fatty acids. It provides us with energy. It is stored as a source of energy (adipose tissue). It protects delicate organs and provides insulation. Fats can be classified as saturated, monosaturated and polyunsaturated. Saturated fats are culprit in heart disease and they increase cholesterol. Monosaturated are fats oils nuts and seeds. They have great health benefits. Polyunsaturated fats are oily fish and vegetable oils and they have been proven to reduce cholesterol. Essential fatty acids are a type of polyunsaturated fat. They cannot be made in the body. They have many health benefits e.g. blood clotting, inflammation and improves immunity. Fats are a source of energy and insulation. They can give the body shape and provide protection to vital …show more content…
To calculate your BMR for Women the formula you use is: BMR = 655 + (9.6 x weight in kilos) + (1.8 x height in cm) - (4.7 x age in years) For men to work out your BMR you use the formula: BMR = 66 + (13.7 x weight in kilos) + (5 x height in cm) - (6.8 x age in years). The BMR in athletes varies in age. The formula for ages 10- 18 years in men is (body weight in kg x 17.5) + 651. In women it is 651 (body weight in kg x 12.2)+ 746. For ages 18-30 in men it is (body weight in kg x 15.3) + 679. In women these ages it is (body weight in kg x 14.7) + 496. Finally for the age group 31-60 years in men the formula is :(body weight in kg x 11.6)+ 879 and for women in this particular age group it is: (body weight in kg x 8.7) + 829.
Factors that affect BMR: Factors that affect your BMR are: your total body weight as the more you weigh the higher your BMR will be. Another factor is age, every year after your 20’s ½ of your body muscle is lost which means your metabolism will decrease. Dieting is also another factor, as is exercise, pregnancy and increased muscle mass. Climate and Gender are also factors that effect a person’s
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
In this lecture, it talks about fat and how it affects us and our bodies. There are two main different types of fat, saturated and unsaturated. Many types of saturated fat are found in meat and dairy products. These fats are hard to break down for cells, because of this, they tend to get tucked away and build up over time if worked off. Unsaturated fats are found in olive oil and other plant oils. These types of fat are readily consumed for energy.
Fats are used to help produce and absorb certain vitamins and hormones. In addition to this, fats 'cushion' vital organs. Fats also act like calorie storage, although this is not their main use. Fats can be found in butter, cheese, oil, and most dairy products. In addition, the body converts extra calories into fat, hence the reason they are like calories storage.
Healthy weight management is more than a diet; weight management is a lifestyle that aims to regulate caloric intake and expenditure in accordance to the amount of physical activity that occurs daily. The goal of weight management is to keep an individual’s body fat content to a healthy minimum, which is important for maintaining overall health and lowering risks of health threats throughout the lifespan (“Assessing Your Weight”, 2015). To measure healthy body fat rates, a Body Mass Index (BMI) is calculated by dividing the weight of the individual by their height squared. Healthy BMI for an individual changes over time
“Nutrition is the science/study of ways in which the body uses food. It is also the study of how and why we make food choices” (Lesson 18). Nutrients are substances in food that provide energy for body tissues and are necessary for life and growth. There are six classes of nutrients: carbohydrates, fats, proteins, vitamins, minerals, and water. Carbohydrates are a class of energy-giving nutrients that include sugars, starches, and fiber. Carbohydrates can be simple (donuts, chocolate, french fries, and gummy bears) or complex (bread, pasta, broccoli, oatmeal, and bananas). Fats are a class of energy-giving nutrients and are the main form in which energy is stored in the body. Fats can be good or bad for you and are either saturated (meats, butter, dairy) or unsaturated (vegetable oils). Proteins are nutrients made up of amino acids, which are needed to build/ repair body structures and to regulate processes in the body. There are incomplete proteins (fruits, vegetables, oats, bread, and rice) and complete (meat and dairy) versions of proteins. Water is an essential class of nutrients that keeps you alive and is necessary for almost every bodily function. Our bodies are made of approximately 60% percent water and because exercise makes you lose water through sweating it is important to drink at least 8 glasses a day. Minerals are a class of nutrients needed for certain body processes such as enzyme activity and bone
Michael Pollan makes arguments concerning the eating habits of the average American. Pollan suggests, in spite of our cultural norms, we should simply “Eat food. Not too much. Mostly Plants.”
My resting heart rate is 64 bpm and my bleep test score (which I aim
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
America is a capitalist society. It should come to a surprise when we live like this daily. We work for profit. We’ll buy either for pleasure or to sell later for profit. It should come to no surprise that our food is made the same way because we are what we eat. We are capitalist that eat a capitalist meal. So we must question our politics. Is our government system to blame for accepting and encouraging monopolies?
The omega-3 fatty acids, popularly referred to as fish oil, are considered unsaturated fats. Science differentiates between unsaturated and saturated fats quite clearly. One fact that separates the two is the temperature at which melting occurs. Saturated fats melt at a higher temperature than unsaturated fats. The science behind fatty acids is rather complex; carboxylic acids with long hydrocarbon chains are the building blocks of saturated and unsaturated fats. This is important to the human body for many reasons; one reason being unsaturated fats do not cause plaque build-up in arteries like saturated fats due to their molecular structure in the human blood stream.
Fatty acids are another type of lipid. The common feature of fatty acids is that they are all esters of moderate to long chain fatty acids. Two polyunsaturated fatty acids, linoleic and linoleic, are designated "essential" because their absence in the human diet has been associated with health problems, such as scaly skin, stunted growth and increased dehydration. These acids are also precursors to the prostaglandins, a family of physiologically potent lipids present in minute amounts in most body tissues.
There are different ways to determine your body composition and the risks that they involve. In this lab, body measurements are taken to find the body percent fat, waist-to-hip ratio, body mass index (BMI), and basal metabolic rate (BMR). Skin folds for the chest, abdomen, and thigh were taken for males, and triceps, iliac crest, and thigh for females. Age, height, and weight for each person were recorded as well as the waist and hip circumference.
The macronutrients a person consumes are what the body needs to function properly. They are the nutrients from protein, fats and carbohydrates that make up a person's daily nutrition. The amount of macronutrients and ratio of one to the other is what people alter to achieve a certain result. For example, lowering carbs and fats while amping up on protein is what body builders do to gain more muscle. Runners will lower protein while increasing carbs to give themselves a rush for a big races.
The First Amendment of the Constitution states that all American’s have the freedom of speech and the freedom of religion. American’s should also have the freedom to consume any food of their choosing because there is no limit to what foods a person should eat. However, there are foods that can lead to an unhealthy life. As a McDonald’s employee, I’ve seen how the food is made, prepared, and cooked… needless to say, it is not appetizing. The food served there has many calories, many grams of fat, and has high cholesterol, yet there are people that still go there every day getting a double cheese burger and a large fry knowing how harmful it can be to their bodies. Americans should have the freedom to choose what food they eat and the lifestyles
