Daily requirements and good non-meat sources of specific amino acids
The requirement for the non-essential amino acids has changed considerably over the last 20 years. The following table lists the recommended daily amounts for adults by the World Health Organization, along with the standard one-letter abbreviation. (Recommended daily intakes for children during their first year can be as much as 150% higher, and 10-20% higher for children three years and older.)…...

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......

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......

Protein Therapies

...Protein therapeutics was once a seldom-used class of treatment. They have increased dramatically since the first protein therapeutic was introduced, insulin. Protein therapeutics are used across every field of medicine. Even with this much dominance, this class of medical treatment still has to be improved. Protein therapies have many advantages when compared to small molecule drugs. Proteins serve a highly specific and complex set of functions that cannot be reproduced by simple chemical compounds. Protein therapeutics can be broken down into groups based on what they can be used for. Group 1 are therapeutics with enzymatic or regulatory activity, Group II includes proteins therapies with special targeting activity, Group III includes protein vaccines, and Group IV includes protein diagnostics. Protein therapeutics are an integral part of medicine. Currently they have been displaying a decreased stability in storage, decreased efficacy and increased immunogenic side effects in patients. Through an enhanced understanding of proteins we can formulate a therapy that will supersede what is currently in use. A research study was done to evaluate the efficacy of a certain variety of protein therapeutics and the obstacles faced when choosing a delivery route. This study pertained specifically to proteins and their ability to treat central nervous system disorders. This article discussed different methods of delivery and each methods set backs. Parenteral delivery routes......

...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......

...the body can be grasped. In particular, I have decided to research Protein macromolecules. Proteins are unique in the way of their structures and found contributing to virtually all cells of the body. The following essay explains the distinctive structures of Protein, variant forms and proteins role toward almost all biological processes. Body: Structure of Protein The structure of a Protein Macromolecule consists of more than one hundred amino acids covalently bonded. A covalent bond is the result of shared electrons amongst atoms and in protein macromolecules; these bonds connect Amino acids to another ultimately creating a Polypeptide chain. A polypeptide chain includes three or more Amino acids linked together by this chemical bond. Amino acids ultimately determine the shape and three dimensional configurations of Protein, are organic compounds and have a two carbon bond comprising of one carboxyl group and one amino group. A carboxyl group (COOH) consists of a carbon atom, two oxygen atoms, Hydrogen atom and joins to an Amine group (NH2) Each amino acid possesses a variable R group differentiating each Amino acid. This R group, (or side chain) gives each protein specific characteristics, including size, polarity and pH according to Boundless Biology (Amino Acids), 01 Dec. 2014. Amino acids contain basic structures of carbon, hydrogen, oxygen, and nitrogen atoms. Once polypeptides have formed, protein molecules are then exposed to four separate organisations of......

Throughout the world, some countries have an abundance of protein resources to keep their population healthy. Other countries lack the ability to maintain proper resources of protein to keep them healthy, and safe from diseases. Proteins provide the amino acids needed for many body functions like communications. Proteins are also out first line defense to our structure. Skin, bones, and muscles are just a few that are supplemented by protein (Grosvenor & Smolin, 2012). Proteins design the neurotransmitter that is how our bodies transport communication around it, and to the brain. Many resources are available to Americans for protein sources. Making the right choices in selections to acquire the daily recommended intake takes knowledge on the quality of proteins. As we take a look at protein we must consider the two types available to us. There are complete and incomplete proteins. Complete proteins provide us a significant source for various amino acids. Complete proteins are resourced from animals and their product sources. Incomplete proteins are comprised of plant sources. Plant proteins are not as abundant in amino acids and in order to receive a full benefit they should be accompanied by a grain source. Plant proteins are harder to digest and without proper digestion the amino acids cannot be extracted from......

...How Protein Assists with Immunity I have recently been turned on to whey protein as a form of meal replacement while on a diet. I was not aware of many of the healthy side effects to the human body and immunity system. I always knew protein had to be part of an everyday healthy diet, but did not know why. According to the article I read, the authors refer to whey as "the magic protein". From a study of whey protein, in the Journal of the American College of Nutrition and Alternative Medicine Review, it enhances the bodies natural production of glutathione, which is our most important antioxidant. Whey protein is made up of many different ingredients or components, and can vary depending on the product. Beta-lactalbumin, Alpha-lactalbumin, Immunoglobulin, Lactoferrin, Lactoperoxidase, Serum Albumin, Glycomacropeptide, and Proteose Peptone are all components that can compose whey. Many of these components are linked to helping the body fight infection, preserve muscle mass, both before and after work outs, as well as have antioxidant, antiviral, anti bacterial, and antifungal properties. Others may help prevent cancer, improve chemotherapy results, and help control blood pressure (Tweed, 2011). From what I can discern from this article, the authors are promoting whey protein as more than just a weight loss, muscle building protein. I was not aware of the benefits available to me. Using this as a meal replacement has help me in many ways. It has enabled me to lose some......
