Protein is an important part of our daily diet. All human beings need it. The Institute of Medicine Recommends adults get a minimum of .8 grams of protein per kilogram of body weight. It is recommended that 10-35% of your required daily calorie intake is made up of protein. Most Americans consume more than enough protein daily, but would benefit from leaner and more varied choices in their protein selections. Protein is found in every body part and our tissues including hair, nails, skin, bones and muscle. It creates the enzymes that fuel several chemical reactions and the hemoglobin that carries oxygen throughout our blood. There are at least 10,000 proteins that make up and maintain us.
Lack of protein can cause many different throughout our body. Some of those include loss of muscle mass weakening of the respiratory system and of the heart. It can cause growth failure and decreased immunity. Protein deficiency can also cause a health condition known as Kwashiorkor a form of protein malnutrition that’s symptoms include anorexia, an enlarged liver, irritability, edema, thinning hair, dermatitis and loss of teeth .
Proteins are created from amino acids, and there are only to ways for our body to create them. They can be made from scratch or by modifying or altering other amino acids. A few essential amino acids can only be gotten from foods, there for high protein food choices certainly play a role in our health and wellbeing .
Protein can be derived from two different food sources, these are animal proteins (meat) and plant proteins (vegetables, fruits, beans and nuts.) What a lot of people don’t know is that these proteins are not creates equal or share the same beneficial properties. Here I will discuss them both...

Proteins are one of the main building blocks of the body. They are required for the structure, function, and regulation of the body’s tissues and organs. Even smaller units create proteins; these are called amino acids. There are twenty different types of amino acids, and all twenty are configured in many different chains and sequences, producing differing protein structures and functions. An enzyme is a specialized protein that participates in chemical reactions where they serve as catalysts to speed up said reactions, or reduce the energy of activation, noted as Ea (Mader & Windelspecht).
Protein have connection with amino acid to help in functions of: skin, muscle, hair and bones
Mr. Smith achieved over 100% of his recommended daily protein. Mr. Smith's health is important for him to keep his protein intake within the recommended range because of the health effects of ingesting too much or too little protein. The effects of too much protein can cause kidney failure.(Too Much, 2006) Too little protein intake can mean low energy, low stamina, poor resistance to infection, mental depression, slow healing of wounds, and prolonged recovery from illness.
About 20% of the human body is made up of protein. Because your body doesn’t store protein, it’s important to get enough from your diet each day.
Many people question whether or not they are taking protein correctly. Then how much to take daily. It is recommended that 25 percent of your daily calorie intake should be protein (Protein). Protein intake can also be seen as 0.6 grams for every pound of weight on a person (Redenbaugh). There are exactly four calories per gram of protein that people ingest when they eat (Redenbaugh). Many people may not want to count the calories and do all of the math, another way people can figure out how much protein that they need, is by looking at the wrappers on food packages. The food label counts the protein in grams, so can just count the grams. The average woman needs forty-six grams a day (Protein). People can compare this to eating two three ounce pieces of chicken breast (Redenbaugh). Don’t worry by eating a healthy meal three times a day should have this covered (Redenbaugh). But when athletes take extra protein for a workout to build muscle they should take in only 60 grams at the most (Truth).
the body's chemical reactions are all made of protein. Without the right proteins, blood won't clot properly and cuts won't heal. Carbohydrates and fat can't meet your energy needs, proteins can. broken down and used as a source of emergency energy. So this makes protein is very crucial for your health.
In order to perform at peak potential an athlete must fuel their body with nutritious foods. Proteins, carbohydrates, fruits and vegetables; these three-core food groups fuel a winning athlete. Proteins help build, teeth, bones and muscles, and create enzymes, red blood cells, long-term energy, as well, boost the immune system. Its functions are the most diverse of any food group. Protein consists of combinations of structures called amino acids that combine in various ways to make muscles, bone and tissues. They serve other functions as well including nutrient transportation and enzyme production for overall health beneficence. Adequate, regular protein intake is essential because the body does not easily store it. Various foods supply protein in different amounts with the highest quantaty coming mostly from animal products such as meat, fish, and eggs.
Proteins that digested inside of the GI tract consist of not only dietary proteins but also 15-25 grams of enzyme proteins. There are customarily about 125 grams of dietary proteins needed per day. The proteins that are secreted inside of the GI tract lumen by its numerous glands and equal about the amount of protein derived from sloughed and disintegrating mucosal cells. Within healthy individuals, nearly all of this protein is digested all the way to its amino acid monomers.
Meat is also the best source of protein and iron which are used a lot. in the body of the body. With vegetables, fruit, and dairy produce a lot must be. eaten to achieve the same amount of protein and iron consumed with a smaller amount of meat. Eating too much vegetables or anything becomes hazardous to the body, therefore eating meat could prevent this problem. and also leave more room in the diet for more food.
If proteins are the building blocks of life, then amino acids are the building blocks of proteins. Plant cells form amino acids from the compounds which the plant draws up from the ground, such as the nitrates and ammonia salts. Animals, however, cannot perform this conversion of simple inorganic substances to amino acids, so they must ingest them in the form of food-- with herbivorous animals consuming plant proteins in vegetables and carnivorous animals consuming animal proteins in the bodies of their prey.
Implications of Protein Deficiency When a person has a deficiency in protein in their diet, they can become. victims of protein energy malnutrition. The malnutrition of protein has many health effects. There are two types of protein energy. malnutrition, the first type is acute protein energy malnutrition.
You've probably heard about how influential protein is to gaining muscle, but it also gives you
According to the book “Understanding normal and clinical nutrition”, the Recommended Dietary Allowance (RDA) for protein intake is, 0.8g/kg of body weight for non-athletes; according to nutrition professionals this amount can be achieved through a healthy diet (Rolfes, Pinna, & Whitney, 2012). It is well known that athletes, due to their high energy expenditure, need to ingest a greater quantity of nutrients with the purpose of repairing and building muscle cells, besides reestablishing energy storage; The International Society of Sports Nutrition (2007) states that athletes and exercising individuals amount of protein to be consumed depends on the intensity of the exercise training sessions, the quality of the protein ingested in their whole foods diet, besides their carbohydrate intake. Meanwhile, athletes’ protein needs should be about 1.4 to 2.0 g/kg of body weight, and even though dietary supplements are a safe way to meet protein requirement, it would be healthier to obtain the necessary nutrients ingesting high quality foods as part of a daily diet (Campbell et al, 2007).
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
Critics of vegetarianism do not believe that going on a plant based diet is the healthier choice. According to Nancy Rodriguez , people need to have a balanced diet consisting of the basic food groups: fruits, vegetables, grains, protein and dairy. Vegetarians are getting the important nutrients from vegetables, fruits, grains, and dairy but are missing important vitamins that they would normally get from proteins, such as, vitamin D, vitamin B12, zinc, iron, and calcium. These nutrients are available in other foods but vegetarians are not able to get it in large amounts as they would be in meat. This insufficient amount of nutrients could create health problems in the future, for example, not having enough vitamin D could lead to bad bone structure. It is true that becoming a vegetarian could lead to some nutritional problems in the body however; there are many more positive aspects in becoming a vegetarian than negatives.
