Perplexed about Protein?
As protein and whey powders have advanced in popularity, the confusion about them has grown. In particular, protein processing technology has advanced by leaps and bounds; consumers are being presented with protein claims and counter-claims that are highly contradictory.
The confusion is part of a rapid growth. Little Miss Muffet’s quiet dish of curds and whey has expanded from a minor sideline aid for weight lifters, with sales increases around to percent a year, into an explosive $1 billion a year industry, with some companies announcing sales growth of 110 percent in just the last year.
The increase in market is from whey’s expanding appeal. As new technology has made whey’s nutritive value beneficial to a wide range of consumers, more people are using whey, and whey is being added to more products. The problem is, those advanced nutritive qualities are not included in all whey products. The fantastic immune benefits, for example, apply to only the top tier of whey products.
The standard of protein quality—the ability to provide indispensable amino acids—is judged on the basis of digestibility, nutrients, and amino acid composition. Whey has historically been acknowledged as on of the best sources of high quality protein.
With the increasing popularity of whey, attention on new processing methods has raised the bar on quality, and new products have greatly expanded nutritional values. What may have been an acceptable high-quality whey protein a few years ago, no longer makes the grade. Tony Lucchesi, Natural Sales Trainer at Source Naturals says, “The different processing methods have changed the entire protein market.”
He explains, “In separating casein from whey, (a process used to make cheese), most processing methods use heat, chemical modification, or pH adjustments. These all damage the native protein structure. The result is little or no biological activity in the whey product. All the low temperature drying and micro-filtration won’t help if the raw material is denatured before a protein is dried and brought to market.”
Damaged protein may have been acceptable a few years ago, but it isn’t now. Lucchesi continues, “Animal experiments have shown that polypeptides—whole, non-denatured proteins—have greater nutritional value than protein isolates.”
Protein isolates are what is left after the pasteurization process. The protein has traditionally been “Cross cooked” out of its normal balance. “What you have left are incomplete bits and pieces of whole protein,” he says. These protein bits have only partial nutrients.
The latest introduction to the protein category are concentrates, which are intact, biologically-active whole proteins. The entire difference is in the processing; high heat, acids, and traditional methods of separating the caseins from the whey are no longer used. The new processing preserves the nutrients of the protein. This is the method that is the basis for a new Source Naturals whey product, True Whey.
Lucchesi says, “TRUE WHEY is different in that it was designed to provide nutritional support for enhanced immune function. The entire process was designed for nutritive value. The preservation of these nutrients—lactoferrin, glutamine, immunoglobulins—give TRUE WHEY a huge benefit to athletes, children, and anyone interested in boosting their immune system.”
Per serving, TRUE WHEY offers 8 grams of un-denatured protein that includes 900 mg immunoglobulins and 190mg of lactoferrin. Its vanilla flavoring has gotten very high reviews, and it has a two-year shelf life. It appears that the bar has truly been raised in the whey protein category!
