Chicken vs Salmon: Which Has More Protein?

When it comes to protein-rich foods, chicken and salmon are two of the most popular options. But if you had to choose just one as your go-to source of dietary protein, which would come out on top – chicken or salmon? Let’s take a detailed look at the nutrition profiles of these proteins and find out which packs more of a protein punch

An Overview of Chicken and Salmon Protein

Both chicken and salmon are considered excellent sources of high-quality protein. Here’s an overview:

• A 3 oz serving of boneless, skinless chicken breast contains around 25-27g of protein. Chicken thighs and legs have slightly less at 22-24g per 3 oz.

• A 3 oz serving of most salmon cuts provides around 17-25g of protein Sockeye salmon is one of the highest at around 23g

So at first glance, chicken seems to be the winner when it comes to total protein content. But to get the full picture, we need to dive deeper into the amino acid profile of these proteins.

Comparing the Amino Acid Profile

When determining protein quality, it’s important to look at the amino acid profile – specifically the essential amino acids that our bodies cannot make on their own. Here’s how chicken and salmon compare:

• Leucine: Salmon contains slightly more leucine than chicken – around 1.8g vs 1.6g per 3 oz serving. Leucine is considered the most important amino acid for stimulating muscle protein synthesis.

• Lysine: Chicken contains more lysine than salmon – around 2.3g vs 2g per serving. Lysine plays a role in calcium absorption and muscle growth.

• Methionine and Cysteine Salmon contains significantly more of these sulfur-containing amino acids than chicken, They play a key antioxidant role

• Tryptophan: Salmon contains more tryptophan than chicken – around 0.3g vs 0.2g. Tryptophan is a precursor to serotonin and helps regulate appetite and sleep.

So while chicken contains more total protein, gram for gram salmon actually contains more of certain essential amino acids like leucine that are critical for muscle growth and performance.

Comparing the Protein Quality Scores

There are a few measures used to score the overall quality of a protein, including:

• PDCAAS (Protein Digestibility Corrected Amino Acid Score): This scores protein quality based on human amino acid requirements and digestibility. Both chicken and salmon score a perfect 1.0 on the PDCAAS scale.

• BV (Biological Value): This measures how efficiently our bodies can actually utilize protein. Salmon has a higher BV than chicken – around 92 vs 76.

So while both chicken and salmon contain complete, high-quality protein, salmon has the edge when it comes to bioavailability and amino acid profile.

Which Has More Protein Per Calorie?

Another way to compare these proteins is to look at how much protein you get per calorie:

• A 3 oz serving of chicken breast with around 25g of protein provides about 120 calories. That equates to 0.21g of protein per calorie.

• A 3 oz serving of salmon with around 23g of protein provides about 175 calories. That comes out to 0.13g of protein per calorie.

So calorie for calorie, chicken gives you more protein bang for your buck. Chicken breast is one of the most protein-dense foods you can eat.

Which Protein is Better for Weight Loss?

For weight loss, protein helps increase satiety, boost metabolism, and preserve muscle mass when cutting calories. So which is better suited as part of a weight loss diet?

• As the more protein-dense food, chicken may have a slight edge for weight loss and fat burning. Replacing carbs and fat with extra protein from chicken can help reduce intake and ramp up fat burning.

• But salmon has its weight loss benefits as well. It’s rich in omega-3s, which have been shown to help reduce inflammation, decrease fat cells, and improve satiety. The high-quality protein supports muscle mass maintenance when losing weight.

Overall both can support weight loss, but chicken breast may be better from a pure protein density standpoint. Salmon offers other nutritional benefits though.

Which Has More Protein: Cooked or Raw?

The cooking method can impact the protein content in both chicken and salmon. Here’s how the protein numbers compare for cooked vs raw:

• Chicken can lose anywhere from 5-15% of its total protein when cooked. The losses are minimized by cooking at lower temperatures but some protein denaturation is inevitable.

• Salmon loses very little (only around 2-5%) of its protein when cooked. The fatty acids in salmon help protect the proteins from excessive heat damage.

So raw salmon actually contains only slightly more protein than cooked. But raw chicken has significantly more pre-cooking – around 30-35g per 3 oz serving. Just keep this protein loss in mind when tracking your intake.

Which Contains More Complete Protein?

Both chicken and salmon contain high-quality, complete protein – meaning they provide adequate amounts of all the essential amino acids.

However, salmon contains higher levels of certain amino acids like leucine that make it a more anabolic protein for supporting muscle growth. The omega-3s in salmon also help reduce muscle protein breakdown.

So while both are complete proteins, salmon may have a slight edge specifically for muscle gain and recovery. But both are excellent dietary sources of complete animal protein.

Which Protein is Healthier Overall?

When assessing overall health impact, salmon comes out on top:

• The omega-3s EPA and DHA in salmon provide heart health benefits including reduced inflammation, lower blood pressure, and decreased risk of heart disease.

• Salmon is also rich in antioxidants like selenium, vitamin D, and astaxanthin that reduce oxidative stress and may protect against cancer.

• The protein and amino acids in salmon help optimize body composition by stimulating muscle growth and burning fat.

So for the average person, getting your protein from salmon offers more potential health benefits beyond just the protein content. The nutritional profile is hard to beat.

The Verdict: Salmon for Quality, Chicken for Quantity

When comparing chicken vs salmon protein, a few key takeaways emerge:

• Chicken breasts provide more total protein per serving and more protein per calorie – making them the winner for pure protein quantity.

• But salmon contains more of certain essential amino acids that better stimulate muscle growth and fat burning. The protein is utilized more efficiently.

• Factoring in the additional omega-3s and antioxidants, salmon offers more overall health benefits.

So while both are high-quality sources of complete protein, salmon delivers superior protein quality with extra nutritional bonuses. But for maximum protein density, chicken reigns supreme gram for gram.

The best approach is to incorporate both as part of a balanced, high protein diet. Chicken provides an efficient protein boost that promotes satiety and weight management. Salmon offers exceptional protein quality and overall nutrition to support optimal health. By combining both, you get the best of both worlds!
