Proteins - essential to growth and repair of muscle and other body tissues
Fats - one source of energy and important in relation to fat soluble vitamins
Carbohydrates - our main source of energy
Minerals - those inorganic elements occurring in the body and which are critical to its normal functions
Vitamins - water and fat soluble vitamins play important roles in many chemical processes in the body
Water - essential to normal body function - as a vehicle for carrying other nutrients and because 60% of the human body is water
Roughage - the fibrous indigestible portion of our diet essential to health of the digestive system
What are the daily energy requirements?

Personal energy requirement = basic energy requirements + extra energy requirements

Basic energy requirements (BER) includes your basal metabolic rate (BMR) and general daily activities

For every Kg of body weight 1.3 Calories is required every hour. (An athlete weighing 50Kg would require 1.3 × 24hrs × 50Kg = 1560 Calories/day)
For a calculation of your BMR, see the calculator on the Resting Daily Energy Expenditure (RDEE) page
Extra energy requirements (EER)

For each hours training you require an additional 8.5 Calories for each Kg of body weight. (For a two hour training session our 50Kg athlete would require 8.5 × 2hrs × 50Kg = 850 Calories)
An athlete weighing 50Kg who trains for two hours would require an intake of approximately 2410 Calories (BER + EER = 1560 + 850)

Energy Fuel

Like fuel for a car, the energy we need has to be blended. The blend that we require is as follows:

57% Carbohydrates (sugar, sweets, bread, cakes)
30% Fats (dairy products, oil)
13% Protein (eggs, milk, meat, poultry, fish)
The energy yield per gram is as follows: Carbohydrate - 4 Calories, Fats - 9 Calories and Protein - 4 Calories.

Protein Research

...Protein Article Research University of Phoenix I use to think of meats or a powdered substance in a big plastic container when I saw the word protein. I now know proteins come in many different forms, and not only from the above mentioned sources. According to “Centers for Disease Control and Prevention” (2012), “The protein in the foods we eat is digested into amino acids that are later used to replace these proteins in our bodies” (Nutrition for Everyone). Proteins in our diet can be found as either complete or incomplete proteins. A complete protein contains all of the essential amino acids. These are sometimes called high quality proteins. Animal-based proteins such as meat, fish and milk are considered complete proteins. An incomplete protein is one that lacks one or more of the essential amino acids. Two or more incomplete proteins consumed together form a complementary protein when they are low in different acids. Together two incomplete proteins can offer all of the essential amino acids the body needs. According to Grosvenor (2006), amino acids are “conditionally essential” meaning they are only needed in certain situations to make proteins the body cannot produce on its own. The nitrogen in amino acids distinguishes protein from fat or carbohydrates. Amino acids provide the nitrogen needed to make a protein. Our DNA provides the roadmap for breaking down proteins and creating other proteins (Nutrition; Everyday Choices). A person’s recommended intake......

Protein

...Protein Article When you think about protein you think about muscle. However, beyond the visible assets of an athlete’s strength, protein is an essential nutrient that the body uses to build new cells, maintain tissues, and help the body perform basic functions. There are two kinds of proteins; complete proteins and incomplete proteins. Complete proteins are also known as high-quality proteins which are found in meat, poultry, fish, eggs, and dairy products. A high-quality protein source is referred to as “Complete” in that it provides all of the essential amino acids that make up a protein. These proteins are also absorbed by the body more efficiently than low-quality proteins. Incomplete proteins, also known as complementary proteins, are not a sufficient source of protein unless combined with other incomplete proteins to supply adequate amounts of essential amino acids. Amino acids are commonly referred to as the building blocks of protein. Essential amino acids are not produced by the body and therefore essential that they are obtained as part of one’s diet. Although amino acids are each composed of hydrogen, an amino group, an acid group, and a side group, each amino acid is unique in structure. The body needs approximately 20 different amino acids to make up the proteins the body needs. These amino acids link up to other nutrients to form different types of compounds through a process called protein synthesis. This process produces lipoproteins, which transport......

Protein

...Protein Article Research Jessica SCI/241 Carolyn Farhy February 19, 2014 Proteins are considered the building block of the body from the amino acids, and are very vital in the maintenance of body tissue, including development and repair. Proteins are part of every cell, tissue and organs in our body. It is broken down and is replaced by the protein that we eat in our diet. Protein is also important for healthy hair, skin, and nails and most importantly, protein will also help our energy level. There are different types of proteins and they correlate with how many amino acids are in the protein. A complete source of protein is one that provides all of the amino acids, while an incomplete protein is low in one or more of the essential amino acids. Finally, a complementary protein has two or more incomplete protein sources that when put together have an enough amounts of all amino acids. There are 20 different amino acids that are found within proteins. We can produce 10 of the 20 amino acids and the remaining needs to be supplied in the food we eat. While protein is a vital part of eating healthy there are certain risks if you don’t get enough or if you eat too much protein. Risks with protein deficiency could include a type of malnutrition would could result in diarrhea, loss of muscle mass, and fatigue. It could also hinder your body by frequent infections and swelling. On the opposite side, protein will contribute to overall calorie intake and animal sources......

Protein Restriction

...PROTEIN RESTRICTED DIET While you need protein for many purposes, like tissue growth and repair, certain conditions can affect your body's ability to break down this nutrient. Examples include liver and kidney disease. Eating a protein-restricted diet can help these kinds of conditions, along with other treatments. WHAT FOODS ARE HIGH IN PROTEIN? MEATS (BEEF, CHICKEN, TURKEY, AND PORK) FISH SEAFOOD (CLAMS, SCALLOPS, AND SHRIMP) EGGS DAIRY PRODUCTS (MILK, CHEESE, ICE CREAM, YOGURT, AND PUDDING) : While dairy products contain protein, patients need to be aware that they might get hypocalcemia. WHAT FOODS ARE LOW IN PROTEIN? CORN ICE CREAM BREAD FRUITS, VEGETABLES CEREAL, OATMEAL CULTURAL CONSIDERATIONS Western families usually consume a large amount of protein in their diets, It is important to involve the whole family and come up with a cooking plan to cook with less protein and sodium, and add more complex carbohydrates to the meals. NURSING CONSIDERATIONS Ensuring Adequate Nutrition * Remember that low-protein does not mean "no-protein." Your body still requires some protein to perform basic repair functions, so do not entirely deprive it of this resource. Ordinarily, you receive most of your fat intake from protein-laden foods such as meat. With heavy meat consumption no longer an option, substitute in various healthy-fat sources such as avocados, coconuts and oils * If you have diabetes or other conditions where you must watch......

Protein Requirements

...Fauna Zeller Protein Requirements The term “high-protein-diet” is reserved for diets with over 50% protein. Research has shown that diets that are higher in protein and lower in carbohydrates are said to reduce blood fats. It also helps maintain lean tissue, while burning fat for fuel. Being on a high protein diet will cut out constant hunger and make your body feel fuller for most of your day. I chose to research the Protein Power diet. This diet regimen is based on the idea that controlling the level of insulin helps regulate blood pressure, cholesterol, triglycerides, and fat storage. Carbohydrates cause the body to produce insulin. High levels of insulin inhibit the breakdown of fatty deposits in the body. Low intake of carbohydrates keeps the insulin levels low, forcing the production of glucagon, which seeks energy from the body’s supply of stored fat. This causes weight loss. At the beginning of the diet, when carbohydrates are restricted, your body will be in a state of ketosis. This is where fat breaks down and excessive amounts of ketone bodies are produced and excreted in the urine. This diet urges you to increase your fluid intake by 50% to rid your body of these ketones. The exercise part of this diet includes a lot or resistance training, like weight lifting. This kind of exercise creates a neuroendocrine response, stimulating the release of growth hormone and testosterone more quickly than aerobic exercise. Growth hormone shifts the......

Proteins

...Protein and the Body Robert Jacob SCI/241 NUTRITION March- seventh-2014 Dr. Nearor Protein and the Body Protein has six primary bodily functions. Protein is used to repair and maintain body tissue as well as your skin, hair, and eyes. It is also used as a major energy source for the body and is involved in the creation of some hormones. Protein increases the rate of chemical reactions in the body in the form of enzymes, and it aids in transportation of certain molecules like hemoglobin; which is a protein that transports oxygen throughout the body. Protein is also responsible for forming antibodies that help stop infection, illness and disease. The "Centers For Disease Control And Prevention" (n.d.) website lists the the two types of proteins as complete proteins; being the one that provides all of the essential amino acids, and incomplete proteins; sources that are low in one or more of the essential amino acids needed to form a complete protein. Complete proteins or high quality proteins are found in meat, poultry, fish, milk and eggs. Incomplete proteins can be found in rice and dry beans. But when consumed together, the rice and beans contain enough amino acids that the body needs. Amino acid content and the sequence of amino acids of a specific protein is determined by the sequence of the bases in the gene that encodes the specific protein. Within the amino acid sequences of proteins we can find the necessary information that will determine how the......

Protein

...Amanda, I read your posting about the benefits about protein in our diets but I specifically focused my response research on the affects too much protein can have on our bodies. You mentioned in your post about high protein diets and how it can damage the kidneys, and I found it particularly interesting and decided to research more. According to research, high protein diets can cause harmful effects on renal (kidney) function and are believed to be due to the overwork induced by such diets on the kidneys (Aparicio, Nebot, Garcia-del Moral, Machado-Vilchez, Porres, Sanchez and Aranda, 2013). High protein diets cause elevation of glomerular filtration rate and hyper-filtration which was concluded through experiments done on pigs who have similar kidneys as humans (Aparicio, Nebot, Garcia-del Moral, Machado-Vilchez, Porres, Sanchez and Aranda, 2013). The kidney plays a central role in protein metabolism and processes regulated by the kidneys are directly affected by dietary protein intake (Aparicio, Nebot, Garcia-del Moral, Machado-Vilchez, Porres, Sanchez and Aranda, 2013). Therefore, Amanda I agree with you that high protein diets are popular amongst today’s society because I am constantly seeing more ads for “high-protein” products that help with weight loss – such as protein shakes and powders- and menu item options when I go out. But we have to be well informed and cautious when consuming protein and how much we should be ingested, because as you can see, it can have......

Protein

...Protein This paper will discuss how proteins contribute to a balanced diet and the discoveries I made when I consciously monitored my caloric intake and specifically the proteins contained within the total intake of calories. Protein is found in every cell in your body and is a necessary part of our diet. Two to three servings of protein each day will help you get the necessary amount of protein, which can help your body's cells and tissues function properly. Protein is an important part of nutrition and different animal and plant sources of protein provide different types of amino acids Proteins are made up of amino acids, which are used to replace old proteins in cells and tissues that have been broken down and need to be replaced. Proteins are biological polymers composed of amino acids. Amino acids, linked together by peptide bonds, form a polypeptide chain. One or more polypeptide chains twisted into a 3-D shape form a protein. Proteins have complex shapes that include various folds, loops, and curves. Folding in proteins happens spontaneously Proteins are made up of amino acids, and they are the “building blocks” of life. Our skin, muscles, tendons, cartilage, even hair and nails, are all because of protein. Protein helps form enzymes, hormones, antibodies and new tissues. It transports important nutrients in and out of those cells. There are nine amino acids known as “essential” amino acids, and therefore must be derived from what we eat. Arginine classified......

Whey vs Soy Protein Topic

...supplementation to exercising that I have come across is whether whey protein or soy protein is better for you. From my general understanding by reading the nutrition labels and light research on the web both helps with building lean muscle, just in different ways. This boils down to the amount of protein in the servings and how it is absorbed in the body. My reasoning for doing this research is so I can not only find out what works best for me but also to be able to explain the differences between the two to friends and others who may have questions about it. Research will have different approaches, views and ideas involved that researchers can use to come to a conclusion about a problem. Philosophical worldviews can be defined as “a basic set of beliefs that guide action” (Creswell, 2013). These views arise from discipline orientations, student advisor/mentor inclinations, and past research experiences which lead to a qualitative, quantitative or mixed method approach in research. The four types of worldviews widely known are postpositivism, constructivism, transformative and pragmatism. The worldview I will be bringing to the study will be of pragmatism. With pragmatism instead of the researcher focusing on methods, there is an emphasis on the research problem and use all approaches available to understand the problem (Creswell, p. 10). With the study that will be done on the differences in types of protein there will be a need for quantitative methods which......

...a tiny amount of vitamins. If our bodies do not have enough on vitamins then we suffer from deficiency which can be harmful to the body, but once we fuel our bodies with the right amount of vitamins that it needs, the symptoms are resolved. Vitamins has be appointed to two different groups depending on how the vitamins are being stored within the human body. The two categories in which the vitamins are assigned to are fat or water depending on the solubility. If the vitamins can break down in fat then the vitamins will be fat-soluble and if they can dissolve in water then the vitamins are water soluble. “This chemical characteristic allows generalizations to be made about how the vitamins are absorbed, transported, excreted, and stored in the body.” (Wiley, 2012). When the vitamins are able to dissolve in either water or fat then they are able to be transported within the body and put to use in the body. Vitamins are alphabetically named by which order they were first identified. Water soluble vitamins consist of the B vitamins as well as the Vitamin C and the fat soluble vitamins consist of A, D, E, and K vitamins. If we eat a healthy well balanced diet we will normally get all the vitamins we need because just about all the foods we eat contain vitamins, but if we do not get all the vitamins we need then that is when vitamin supplements are taken. The human body cannot make all vitamins so the body will have to get the daily amount from the foods you intake. Vitamins are......

Protein

...We all know that we need protein in our diet, but not everyone understands why. There are several ways people consume protein such as shakes, fad diets and pills, but it is not necessary if you eat the right foods. According to Centers for Disease Control and Prevention (2012), “You might think Americans were at risk for not eating enough. In fact, most of us eat more protein than we need.” Our bodies contain numerous key elements in every single one of our cells. Proteins are vital to the way we function. Because of this, our bodies are consistently working to utilize and replenish the proteins we consume. Protein is what builds, repairs, and maintains our body tissues (ex. hair, skin, organs, muscles, etc.) and gives us energy. It also assists with the production of certain hormones, enzymes and helps our bodies build antibodies to fight off infections and diseases. * Proteins are made up of 20 different amino acids, which is why they are so effective. When amino acids join together, different proteins can be created. Our bodies are capable of making some amino acids, but there are others that we can only get from our diet. These are referred to as essential amino acids. There are two different labels we use to categorize protein sources now. The first is a complete protein source. What makes it complete is that it provides you with all of the essential amino acids that your body needs. If the protein source lacks one or more of the essential amino acids, it is......
