What is Protein ? Back to top Proteins are compounds of carbon, hydrogen, oxygen and nitrogen. Protein is essential for growth and repair of the body, in must by provided by our diets and any excess can be used as energy. Protein consists of hundreds of amino acid units, only about 20 different amino acids are used. There is pore protein in your body than any other substance except water.
Amino acids are the building blocks of protein. They acids are needed to build the various proteins used in the growth, repair, and maintenance of body tissues. Eleven of these amino acids can be made by the body itself, while the other nine (called essential amino acids) must come from the diet |

Amino acids Back to top Amino acides can be divided into two types,
Essential Amino Acids which cannot be made in the body. Back to top Isoleucine
provide ingredients for the manufacturing of other essential biochemical
components in the body, some of which are utilized for the production of
energy, stimulants to the upper brain and helping you to be more alert.

Insures the adequate absorption of calcium; helps form collagen which
makes up bone cartilage & connective tissues aids in the production of
antibodies, hormones & enzymes. Recent studies have shown that Lysine may
be effective against herpes by improving the balance of nutrients that
reduce viral growth. A deficiency may result in tiredness, inability to
concentrate, irritability, bloodshot eyes, retarded growth, hair loss,
anemia & reproductive problems. Is a principle supplier of sulfur which prevents disorders of the hair, skin and nails; helps lower cholesterol levels by increasing the liver's production of lecithin; reduces liver fat and protects the kidneys; a natural chelating agent for heavy metals; regulates the formation of ammonia and creates ammonia-free urine which reduces bladder irritation; influences hair follicles and promotes hair growth Phenylalanine Used by the brain to produce Norepinephrine, a chemical that transmits signals between nerve cells and the brain; keeps you awake & alert; reduces hunger pains; functions as an antidepressant and helps improve memory Threonine Is an important constituent of collagen, Elastin, and enamel protein; helps prevents fat build-up in the liver; helps the digestive and intestinal tracts function more smoothly; assists metabolism and assimilation Tryptophan A natural relaxant, helps alleviate insomnia by inducing normal sleep; reduces anxiety & depression; helps in the treatment of migraine headaches; helps the immune system; helps reduce the risk of artery & heart spasms; works with Lysine in reducing cholesterol levels Valine Promotes mental vigor, muscle coordination and calm emotions. Non Essential Amino Acids can be produced in the body. Back to top Most meat and dairy products are considered to be complete protein because the contain all the essential amino acids and vegetable foods are considered incomplete protein because they only contain some of the essential aminos, however a mixture of different vegetables can contain all of the aminos required.
Other sources of protein include, texturised vegetable protein-developed by isolating proteins from a number of plants, including Soya beans, and converting them into mince of chunks. Mycroprotein-(quorn) is grown from a type of edible fungus, and transformed into a meat alternative, it is quite nice actually.
Alanine Is an important source of energy for muscle tissue, the brain and central nervous system; strengthens the immune system by producing antibodies; helps in the metabolism of sugars and organic acids Arginine
Studies have shown that is has improved immune responses to bacteria,
viruses & tumor cells; promotes wound healing and regeneration of the
liver; causes the release of growth hormones; considered crucial for
optimal muscle growth and tissue repair. Aids in the expulsion of harmful ammonia from the body. When ammonia enters the circulatory system it acts as a highly toxic substance which can be harmful to the central nervous system. Recent studies have shown that Aspartic Acid may increase resistance to fatigue and increase endurance Asparagine Cysteine Functions as an antioxidant and is a powerful aid to the body in protecting against radiation and pollution. It can help slow down the aging process, deactivate free radicals, neutralize toxins; aids in protein synthesis and presents cellular change. It is necessary for the formation of the skin, which aids in the recovery from burns and surgical operations. Hair and skin are made up 10-14% Cystine Glutamine Considered to be nature's "Brain food" by improving mental capacities; helps speed the healing of ulcers; gives a "lift" from fatigue; helps control alcoholism, schizophrenia and the craving for sugar Glycine Helps trigger the release of oxygen to the energy requiring cell-making process; Important in the manufacturing of hormones responsible for a strong immune system Proline Is extremely important for the proper functioning of joints and tendons; also helps maintain and strengthen heart muscles. Serine A storage source of glucose by the liver and muscles; helps strengthen the immune system by providing antibodies; synthesizes fatty acid sheath around nerve fibers Tyrosine Transmits nerve impulses to the brain; helps overcome depression; Improves memory; increases mental alertness; promotes the healthy functioning of the thyroid, adrenal and pituitary glands Taurine
Helps stabilize the excitability of membranes which is very important in
the control of epileptic seizures. Taurine and sulfur are considered to be
factors necessary for the control of many biochemical changes that take
place in the aging process; aids in the clearing of free radical wastes.
Is found abundantly in hemoglobin; has been used in the treatment of
rheumatoid arthritis, allergic diseases, ulcers & anemia. A deficiency can
cause poor hearing. The daily recommended amount of protein varies in opinion, some experts say 0.42 grams per day per pound of body weight which is rather low others say 1.0 grams. The amount you need really depends on what and how much physical exercise you perform, large bodybuilders sometimes eat up to 2.0 grams. It is better to eat slightly more than you need, but a stuffing yourself with protein is not a good idea and will probably end up as body fat, it will also put a strain on the liver and kidneys. If you are not sure ask your personal trainer for advice.
Food Source of Protein Back to top Foods of animal origin, such as meat and poultry, fish, eggs, and dairy products, are the richest dietary sources of the essential amino acids. Plant sources of protein are often deficient in one or more essential amino acids. However, these deficiencies can be overcome by consuming a wide variety of plant foods. For example, grains are low in lysine, whereas beans provide an excess of lysine. It was previously believed that, in order for vegetarians to obtain adequate amounts of protein, all of the essential amino acids had to be balanced at each meal. For example, a grain and a bean had to be consumed at the same meal. |
