The Surprising Nutritional Benefits of Salmon Skin

Salmon is widely recognized as one of the most nutritious fish you can eat but it turns out the skin might be just as beneficial as the fillet itself. While many people discard salmon skin or peel it off before cooking, doing so may mean missing out on a surprising amount of protein, healthy fats, and key nutrients.

Here’s why eating salmon skin could be a smart (and tasty) addition to your meals and how to prepare it for maximum benefit.

1. A Surprising Source of Protein

One crispy salmon skin snack (about 15 grams or half an ounce) can pack 10 grams of protein, making it a valuable addition for anyone looking to support muscle repair, growth, or post-workout recovery. Protein also plays a key role in maintaining hair, skin, and nail health.

2. Rich in Omega-3s and Healthy Fats

Salmon skin contains omega-3 fatty acids, the same heart-healthy fats found in the flesh. These fats help support brain function, reduce inflammation, and may even lower the risk of chronic diseases like heart disease and certain cancers. The exact amount of omega-3s can vary depending on whether the salmon is wild or farm-raised, but the skin is typically one of the densest sources.

3. Low in Carbohydrates

If you're following a low-carb or ketogenic diet, salmon skin is a snack-friendly option. It's naturally carb-free, though it's important to check the label if you're buying packaged salmon skin chips, as some brands add flour or sugar-based seasonings.

4. May Support Bone and Joint Health

Salmon skin’s protein, vitamin D, and omega-3 content may support bone density and reduce joint inflammation. Vitamin D helps your body absorb calcium, which is vital for skeletal strength, especially as we age.

5. Supports Heart and Cognitive Function

The omega-3s in salmon skin have been linked to:

• Lower blood pressure

• Reduced triglyceride levels

• Improved brain health and memory

• A reduced risk of Alzheimer’s disease and other cognitive disorders

6. Promotes Eye Health

Omega-3 fatty acids are also known to protect against age-related macular degeneration (AMD), one of the leading causes of vision loss in older adults.

7. May Improve Skin, Hair, and Wound Healing

Protein, antioxidants, and omega-3s in salmon skin may promote skin elasticity, hydration, and cell repair. Some studies even suggest that gelatin derived from salmon may assist in wound healing, especially in diabetic models.

8. Can Support Gut Health

Emerging research suggests that omega-3s may play a role in maintaining a healthy gut microbiome and reducing intestinal inflammation. While more human studies are needed, salmon skin may support digestive health when included as part of a balanced diet.

9. Delivers Essential Vitamins and Minerals

Although exact micronutrient content can vary, salmon skin may offer trace amounts of:

• Vitamin B12 and B6

• Selenium

• Niacin

• Potassium

• Vitamin D

These nutrients support everything from nerve function to energy metabolism.

Is Salmon Skin Safe?

For most people, yes. But there are a few considerations:

• Fish allergies: Salmon skin can trigger reactions just like the flesh.

• Environmental contaminants: Like all fish, salmon may carry trace amounts of PCBs, microplastics, or heavy metals. However, salmon (especially wild-caught) is still considered a low-mercury fish and safe to consume 2–3 times per week.

• Pregnancy and children: Pregnant individuals and young children may wish to limit salmon skin consumption due to potential contaminants.

How to Cook and Eat Salmon Skin

Cooked salmon skin is safe, flavorful, and versatile. Here’s how to enjoy it:

Best Cooking Methods

• Pan-frying or grilling: Produces crispy skin with rich flavor.

• Baking or roasting: Yields a softer texture but still delicious.

• Dehydrating or air-frying: Creates crunchy snacks or “salmon bacon.”

Remove scales before cooking for better texture and taste. You can cook salmon skin attached to the fillet or separately.

Recipe Ideas

• Crisp it up and serve over a rice bowl

• Oven-roast with soy, ginger, and garlic for a crunchy snack

• Pan-fry and add to salads for a protein-rich topping

• Make salmon skin chips or jerky

Where to Find It

You can buy salmon with the skin on from most grocery stores or fish markets. Ask your fishmonger to leave the skin intact or, if you’re feeling adventurous, request just the skin for cooking. Packaged salmon skin snacks are also available online and in specialty food stores.

Final Thoughts

If you’re already eating salmon, don’t toss the skin it’s one of the most nutrient-dense parts of the fish. With its rich supply of protein, omega-3s, and antioxidants, it supports everything from heart health to glowing skin. Just cook it properly, and you’ve got a flavorful, crispy, and incredibly nourishing upgrade to your next meal.
