You’re scanning the nutrition facts on a bag of tasty pork rinds and pause in confusion. Despite boasting 20g of protein per serving, the label proclaims pork rinds are “not a significant source of protein.” What gives?
This puzzling protein paradox plagues many pork rind fans. Before you toss your bag in dismay, let’s unpack why pork rinds’ ample protein stats don’t tell the full nutritional story.
The Pork Rind Protein Puzzle
At first glance, pork rinds appear protein-packed. A 1-ounce serving often provides around 20 grams of protein – the equivalent of three large eggs or a quarter-pound burger patty.
With such sizable protein quantity how can pork rinds not be a significant protein source? The answer lies in protein quality.
Complete vs. Incomplete Proteins
Not all proteins are created equal. To understand pork rinds’ protein limitations, it helps to know about complete and incomplete proteins.
Complete Proteins
Complete proteins contain all nine essential amino acids required for human health
- Histidine
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
Complete protein sources include meat, eggs, dairy, soy, quinoa and buckwheat. Consuming varied complete proteins ensures your body has the essential amino acids it needs.
Incomplete Proteins
Incomplete proteins lack one or more of the nine essential amino acids. Plant sources like fruits, vegetables, nuts and seeds mostly provide incomplete proteins.
While many incomplete proteins contain ample protein quantity, the quality suffers without those key amino acids. Eating incomplete proteins alone may lead to deficiency despite high protein totals.
Assessing Pork Rind Protein Quality
Now back to pork rinds. Here’s a breakdown of their protein stats:
-
High quantity – About 20g protein per serving
-
Low quality – Lacks some essential amino acids
Although pork rinds contain a hefty protein dose, their amino acid profile is incomplete. Let’s examine why pork rinds come up short on protein quality.
Missing Amino Acids
The protein in pork rinds is limited by low levels of certain amino acids:
-
Methionine – important for metabolism and tissue growth
-
Tryptophan – precursor of serotonin that regulates appetite
-
Histidine – aids tissue repair and helps produce blood cells
Without adequate amounts of these key amino acids, pork rinds’ protein can’t sufficiently support the body despite an abundant total quantity.
Minimal Muscle Meat
Pork rinds consist mostly of fried pig skin, with very little meat protein. The small amount of meat or muscle protein present contains incomplete protein.
Heavy Processing
The high heat and pressure used to produce pork rinds may destroy heat-sensitive amino acids like tryptophan. This further degrades pork rinds’ protein value.
How Protein Quality Is Assessed
Specialized measurements allow nutrition scientists to assess overall protein quality beyond just crude quantity. Two important lab analysis methods are:
Protein Digestibility Corrected Amino Acid Score (PDCAAS)
This test measures a protein’s essential amino acid composition and digestibility. PDCAAS rates proteins on a 0-1 scale, with higher scores indicating better quality. Pork rinds score 0.542 on the PDCAAS scale, while beef scores 0.92.
Digestible Indispensable Amino Acid Score (DIAAS)
This test also evaluates digestibility but focuses solely on essential amino acids. Again, pork rinds’ DIAAS comes in lower than beef, chicken, eggs and other complete protein foods.
Both PDCAAS and DIAAS confirm pork rinds’ protein, while abundant, lacks nutritional quality compared to meat, dairy, eggs and soy.
The Takeaway on Pork Rind Protein
While pork rinds offer indulgent crunch and flavor, their incomplete protein limits their ability to properly support the body’s amino acid needs. Relying solely on pork rinds could result in deficiency despite their seemingly high protein.
For sound nutrition, enjoy pork rinds in moderation alongside varied complete protein sources. Pork rinds pair well with Greek yogurt, edamame, nuts and other complete proteins.
By thoughtfully combining porky deliciousness with proper protein balance, you can continue to savor crispy pork rinds as part of a healthy, amino acid-rich diet. Just don’t expect pork rinds alone to provide top-notch protein nutrition on their own.
Frequently Asked Questions
