2885 Shaughnessy St. • Port Coquitlam, BC • (778) 285-WHEY • www.onewhey.ca • [email protected] The Right Whey Protein By Cory Holly Whey is a derivative of milk, produced as a watery, sidestream product during the manufacturing of cheese. Cheese consists primarily of milk curd, which is a soft gel formed when casein, the most abundant protein in cow’s milk, reacts with lactic acid converted from lactose (milk sugar) by microorganisms in the milk. Milk curd contains most of the milk fat, some whey and many other water-insoluble substances. Fresh liquid whey is mostly water and lactose. In its original and raw form, fresh whole whey has a similar effect on the digestive tract to that of yogurt, and is regarded as a natural cleanser and remedy for many intestinal complaints. I first read about whey as a health food in Dr. Paavo Airola’s 1971 classic book Are You Confused? Airola describes whey as a national food in Sweden where it is traditionally used to prevent internal sluggishness, gas, bowel putrefaction and constipation. But there is something even more special about whey, especially for athletes and those of us committed to the active lifestyle. Whey contains an extensive range of remarkable proteins called "whey peptides" which provide the highest quality source of protein known — higher than eggs, fish, turkey, beef or soy. Whey protein is also "cleaner" than commercial animal proteins, less susceptible to oxidant and free radical conversion and carries virtually no risk of parasite, pathogen or infective microorganism exposure. Cooking Denatures Protein Cooking reduces the biological value of protein. Exposure to high-heat ruptures the bonds that hold peptides together causing a cross-linking effect. Few of us eat wild, raw animal protein, which is actually alkaline forming, high in bioactive micronutrient and enzyme value and conducive to adrenal function, general survival and good health. Protein is our only source of essential amino acids and nitrogen, and therefore its rate and percentage of absorption and utilization is enormously important to health and fitness. Nitrogen is critical to tissue growth, wound healing and the formation of creatine, niacin, B12 and even our genetic hardware. In essence, human cells function as mini-protein factories. Only 0.6% of whey is protein, which means it takes approximately 229 litres of milk to produce one kilogram (1000mg) of concentrated, high-quality whey protein. The trick is to extract the fullest and most complete spectrum of peptides possible without damaging their structure or affecting their health enhancing properties. That means no heat, no chemicals and starting with the highest grade of whey available (preferably Canadian whey). 2885 Shaughnessy St. • Port Coquitlam, BC • (778) 285-WHEY • www.onewhey.ca • [email protected] Whey Peptides Whey peptides are comprised of two or more amino acids linked together in sequence, like the pearls of a necklace. Each pearl represents a single amino acid, such as tryptophan or leucine. When two amino acids are connected to each other they become a peptide. A dipeptide is defined as two amino acids joined together by a peptide (disulfide) bond. Carnosine is a dipeptide consisting of alanine and threonine. Three amino acids joined together form a tripeptide, such as glutathione (cysteine-glutamate-glycine). Polypeptides are formed by an indefinite number of amino acids. Human growth hormone (hGH) is a polypeptide hormone consisting of 191 amino acids. Whey peptides vary in size, molecular weight and function. For instance, beta-lactoglobin, which is a medium weight whey peptide, is recognized as one of nature’s best sources of branched-chain amino acids. The branched-chain amino acids or BCAAs, protect against muscle loss when dieting and supply extra energy for strenuous workouts. Many athletes use whey protein exclusively for BCAAs, as they also spare muscle proteins depleted through highvolume and high-intensity training. BCAAs help keep your anabolic drive alive. Another newly discovered whey peptide of low molecular weight, is called glycomacropeptide (GMP). This peptide is known to suppress appetite, reduce blood stickiness, function as an antibacterial and even reduce tartar adhesion in teeth! GMP also contains a very unique compound called sialic acid, which acts like an anchor in the GI tract to neutralize common viral infectants. Other important whey peptides include lactalbumin, lactoferrin, bovine serum albumin (BSA), immunoglobulins, lactoperoxidase, peptones and lactophan. Extraction & Filtration Methods The best whey proteins are derived from ultra-high quality whey protein concentrate (WPC), which is created after whole whey has been dried and filtered to remove most of its lactose, minerals and fat. The next step involves the technology of enzyme hydrolysis and several extraction and special filtration methods, including cross-flow ultrafiltration, microfiltration, ion-exchange, nanofiltration, diafiltration and reverse osmosis. Each particular method of extraction is crucial to the performance and activity of each specific whey peptide, which explains why none of these advanced extraction methods is necessarily superior to the other. For example, ion-exchanged whey protein is rich in high molecular weight immunoglobulins and whey growth factor extract (WGFE) but the process produces virtually no bioactive GMPs. Ion-exchanged whey protein is also high in sodium and requires additional filtration to improve its protein concentration. Crossflow membrane ultrafiltration is best for GMP production and retains a higher proportion of calcium, but it reduces bovine serum albumin (BSA) which is known to boost immune function by increasing glutathione. Combining several extraction methods is actually the best "whey" to go as such a blend will 2885 Shaughnessy St. • Port Coquitlam, BC • (778) 285-WHEY • www.onewhey.ca • [email protected] result in a highly functional, proprietary supreme blend. But a product derived from only one method such as cross-flow ultrafiltration still has outstanding application. The biological values of various filtration and extraction methods will be similar but the functional properties of each product will relate to their peptide displacement and concentration. Lactose and milk fat may also vary per serving. Engineered whey protein isn’t cheap and expect to pay even more for a supreme blend. Combining different extraction methods costs more to manufacture and the taste and texture of the end product is difficult to attend. Choose a NAME BRAND when selecting a whey protein. Buy from a company who has earned a reputation for quality and maintains a manufacturing environment which complies with Good Manufacturing Practice (GMP) in Canada. Quality control is enormously important, as whey proteins are classified as foods in Canada and seldom undergo extensive analytical testing to verify their contents, biological value, whey peptide percentage and label claims. Cory’s Secret Recipe For Health Whey peptides are clearly established as one of the best single choices when selecting a protein supplement for yourself or your family. They deliver muscle-building nitrogen faster, and when stacked into a healthy diet, they provide multiple health benefits that everyone can enjoy, regardless of age. Add one or two scoops of whey protein to 1 cup of filtered water and combine with one tablespoon of The Sport Oil and your favorite fresh fruit, such as papaya, kiwi, pineapple, banana or frozen berries. If you want to spice it up with more power or prevent exhaustion, add 2-5 grams of creatine monohydrate and 2-5 grams of L-glutamine. Use bodyweight and activity level as a guiding force to determine appropriate amounts. Now you’ve got my secret recipe for health and vibrant living — don’t underestimate it!

High temperature denatures protein and reduces its biological value. This can adversely affect tissue repair and wound healing, and potentially compromise enzyme activity, immune function, hormone production and neuropeptide transmission.
