The

The "Beef Protein" Fad

Past now you may have seen "beefiness poly peptide powder" advertising 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.

Nosotros all like to romanticize with the idea that beef protein is filet mignon grinded into pulverisation, only information technology is merely not. The price of beef is exuberant, making this incommunicable. A quick search on the internet shows that the top 5 selling beef protein products contain the following ingredients:Hydrolyzed beefiness protein isolate,Hydrolyzed gelatin. Now these sound fancy, but what exactly are they? Hydrolyzed Beefiness Protein Isolate is besides known asCollagen. Collagen is not a consummate protein source, and is loftier in glycine, proline, arginine, and hydroxyproline. All these labels are but fancy words for what beef protein actually is: collagen, gelatin, and left over scraps.

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

Amino Acids Whey protein isolate (1000/100g) Beef poly peptide isolate (g/100g)

Gelatinone
(k/100g)

(*=Essential)

Tyrosine two.35 0.9 0.5
Valine (BCAA)* four.48 2.8 two.ii

The first thing you should notice is the glaring similarities between beef poly peptide isolate and gelatin. They are nearly identical, so for the purposes of comparisons between whey and the other two, we volition merely compare whey vs. beef protein isolate. Call up, we are not comparing whey protein isolate to a steak dinner here! This is a comparison of "beef protein powders" to whey protein powders.

Find that at that place are some massive differences. The whey product has much more than of the essential amino acids and BCAAs (34.96 grams in whey vs. 19.4 grams in beef protein isolate per 100 one thousand). The amount of essential amino acids and BCAAs are what nosotros really want to consider when we wait at different sources of protein as athletes when it comes to determining what is best for our lifestyles. These are the amino acids that assistance in recovery, muscle protein synthesis, etc.

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

If that doesn't accept you sold, this should. This is a comparison of the various poly peptide sources we have been discussing using the Protein Digestibility Corrected Amino Acid Score (PDCAAS). The PDCAAS is a method utilized by government agencies that measures the quality of protein based on the amino acid requirements of humans and their power to assimilate these protein sources (2). A value of ane.00 is the highest possible PDCAAS score.

Source PDCAAS 3, 4
Milk poly peptide (used in Select Protein) i.00
Whey protein (used in Select Protein) 1.00
Beef protein (from actual beef, equally in a steak or basis beef) 0.92
Gelatin 0.00
Collagen 0.00

Every bit previously discussed, most of beef protein powders contain mainly collagen and gelatin, thus they take a PDCAAS of nil. As a consumer, yous have to put the trust in the visitor you are purchasing from in hopes that your beef poly peptide powder is actually beef, and not collagen, gelatin, and scraps. Because equally far equally these companies are concerned, they tin can both exist labeled as "beefiness" since they originate from a cow. Collagen and gelatin-loaded products are not benign for athletes and are non a significant source of poly peptide. In fact, next fourth dimension yous are in a store, pick upwardly a pocketbook of pork rinds (gelatin and collagen) or some of your favorite gelatin-brand fruity snack, and you volition run across that the large companies who follow compliance volition have a notation on their labels stating the protein is "Not a significant source of poly peptide".
