The

The "Beefiness Protein" Fad

By at present you may have seen "beef protein pulverization" advert that it is a suitable alternative to milk and whey based proteins. The important question however, is: whatisbeefiness protein powder? Beef is quite a broad term.

We all like to romanticize with the idea that beef poly peptide is filet mignon grinded into powder, but information technology is simply not. The cost of beef is exuberant, making this impossible. A quick search on the internet shows that the top 5 selling beef protein products contain the post-obit ingredients:Hydrolyzed beefiness poly peptide isolate,Hydrolyzed gelatin. Now these sound fancy, but what exactly are they? Hydrolyzed Beefiness Poly peptide Isolate is also known equallyCollagen. Collagen is non a complete protein source, and is high in glycine, proline, arginine, and hydroxyproline. All these labels are simply fancy words for what beef protein really is: collagen, gelatin, and left over scraps.

Beneath is an amino acrid breakdown of an unnamed whey protein production vs. an unnamed beef poly peptide product vs. gelatin (turn sideways on mobile):

The commencement thing you should notice is the glaring similarities between beef protein isolate and gelatin. They are most identical, and then for the purposes of comparisons between whey and the other two, we will but compare whey vs. beef protein isolate. Remember, nosotros are non comparison whey protein isolate to a steak dinner here! This is a comparison of "beef protein powders" to whey protein powders.

Detect that there are some massive differences. The whey product has much more of the essential amino acids and BCAAs (34.96 grams in whey vs. 19.four grams in beefiness protein isolate per 100 m). The amount of essential amino acids and BCAAs are what we really want to consider when we expect at different sources of poly peptide as athletes when information technology comes to determining what is best for our lifestyles. These are the amino acids that aid in recovery, muscle protein synthesis, etc.

Another massive difference is the amount of glycine in beefiness protein (beef protein isolate contains 20.1 grams of glycine, more than 14 times the amount of glycine in whey poly peptide). Glycine is a filler amino acid added into products to devalue the cost of the production. Glycine comes up on lab tests that test for protein content based on nitrogen content as protein, which allows companies to pad the amount of protein in their production by stuffing them with glycine.

If that doesn't accept you sold, this should. This is a comparing of the various protein sources we accept been discussing using the Poly peptide Digestibility Corrected Amino Acid Score (PDCAAS). The PDCAAS is a method utilized past government agencies that measures the quality of protein based on the amino acrid requirements of humans and their ability to digest these poly peptide sources (2). A value of i.00 is the highest possible PDCAAS score.

Source PDCAAS 3, 4
Milk poly peptide (used in Select Poly peptide) ane.00
Whey protein (used in Select Protein) 1.00
Beef protein (from actual beef, as in a steak or ground beefiness) 0.92
Gelatin 0.00
Collagen 0.00

As previously discussed, most of beef protein powders contain mainly collagen and gelatin, thus they have a PDCAAS of nil. As a consumer, you have to put the trust in the company you are purchasing from in hopes that your beef poly peptide powder is really beef, and non collagen, gelatin, and scraps. Considering as far every bit these companies are concerned, they can both be labeled as "beef" since they originate from a cow. Collagen and gelatin-loaded products are not beneficial for athletes and are not a significant source of protein. In fact, next fourth dimension you are in a shop, pick upwards a bag of pork rinds (gelatin and collagen) or some of your favorite gelatin-make fruity snack, and you volition encounter that the large companies who follow compliance volition have a note on their labels stating the poly peptide is "Not a significant source of poly peptide".
