Personal Trainers at Greece NY Assess the Qualities of Different Protein
Do not know what to look for in a protein supplement? Can't decide on the the best source of protein in your diet? Whether it is eggs, beef, whey protein, casein protein or soy protein, you might like to learn more on which of these products are best for your needs.
Biological Value (BV)
The Biological Value measures how well the body can absorb and utilize a protein. The higher the BV of the protein used, the more nitrogen the body can absorb, utilizes and retains. For example, beef rates at 80 whereas bean proteins only rate at 49.
Net Protein Utilization (NPU)
This is the amount of amino acids converted to protein by the body compared to the amount of amino acids from protein that was consumed. A percentage value of 100 means that the body uses 100% of the protein provided. For instance, whey isolate has 100% NPU value versus tofu at 64%.
Protein Efficiency Ratio or PER
The protein efficiency ratio (PER) is based on the weight gain of a test subject (mainly lab rats) divided by its intake of a particular food protein during the test period. Unfortunately, rats handle protein differently than humans and may cause slight calculation errors. The FDA uses this ratio to calculate the recommended daily allowance of protein on food labels
Amino Acid Score (AAS)
The AAS measures essential amino acids in a protein compared to a reference protein. Unfortunately, the AAS does not consider the digestibility of the protein. A value above 1 suggests that the protein contain an amount of essential amino acids that humans require. Example: Whole egg protein - Lysine (78), threonine (86), histidine (96).
Protein Digestibility Corrected Amino Acid Score or PDCAAS
PDCAAS is the Amino Acid Score (AAS) with an added digestibility component. The PDCAAS is the currently accepted measure for protein quality. PDCAAS is based on the amino acid requirements adjusted for digestibility of a pre-school child (determined to be the most nutritionally-demanding age group). For example, a beef with a high score of .92 PDCAAS means that it provides approximately 92% of protein synthesis for the human body.
The Essential and Non-Essential Amino Acids
Essential amino acids are amino acids that are needed by the human body but cannot be made by the body; therefore, they have to be provided for in the diet.
Glutamine - a non-essential amino acid
Glutamine is a non-essential amino acid that is found in massive amounts in the muscles of the body. Because it easily passes through the blood-brain barrier, it is also known as a brain fuel. Glutamine can be converted to glucose and used for energy rather than blood sugar. Glutamine also increases growth hormone levels thereby increasing muscle cell volume as well.
Arginine - non essential
Arginine is a nonessential amino acid. It can be manufactured by the human body, and does not need to be obtained directly through the diet. Individuals who have poor nutrition or certain physical conditions may be advised to increase their intake of foods containing arginine. It also releases insulin and growth hormones in the body during intense exercise for promoting muscle growth. Studies show promising results in the arginines role in increasing fat metabolism.
The twenty-one standard amino acids are either used to synthesize proteins and other biomolecules or oxidized to urea and carbon dioxide as a source of energy. About 10 are essential. This means that they need to be included in the diet for a complete protein source. You may combine two or more incomplete protein sources such as rice and beans to make a complete source.
A diet that contains adequate amounts of amino acids (especially those that are essential) is particularly important in some situations: early development, puberty, pregnancy, lactation, or injury and for building muscle. For muscle building, pick a protein supplement or add to your diet foods that score high in several of the standards mentioned here.
