What Are Canned Sardines?
Sardines are small, oily fish that belong to the herring family. They are found in abundance in the Atlantic, Pacific, and Mediterranean and have been a staple food for centuries. Canned sardines are simply fresh sardines that have been cleaned, cooked, and preserved in a can, usually with oil, water, or sauce.
Many people love sardines for their rich, slightly salty flavor and soft texture. But beyond taste, they offer a ton of health benefits—more on that soon!
Fun Fact: Sardines got their name from the Italian island of Sardinia, where they were once found in large numbers.
Why Are Sardines Canned? The Preservation Process
Canning is a method that locks in freshness and nutrients while giving sardines a long shelf life. Here’s how the process works:
- Harvesting: Sardines are caught fresh from the ocean.
- Cleaning: The fish are washed and gutted.
- Cooking: They are either steamed or fried before being packed.
- Canning: The sardines are placed in a can and covered with oil, water, or sauce.
- Sealing & Sterilization: The can is vacuum-sealed and heated to kill bacteria, ensuring long-term preservation.
Unlike fresh fish, canned sardines don’t require refrigeration until opened. This makes them an easy and accessible source of protein for people all over the world.
Nutritional Value of Canned Sardines
If you think sardines are just a salty snack, think again! These tiny fish are one of the most nutrient-dense foods you can eat. Here’s a breakdown of what you’re getting in a typical 3.75-ounce (106g) can of sardines:
| Nutrient | Amount Per Serving | % Daily Value |
|---|---|---|
| Calories | 190 | 9.5% |
| Protein | 22g | 44% |

| Calcium | 35% of RDI | – |
| Vitamin B12 | 150% of RDI | – |

Protein Powerhouse: How Sardines Support Muscle Growth

Are Canned Sardines High in Mercury? Understanding the Risks
One concern people have about eating fish is mercury contamination. Luckily, sardines are one of the safest seafood choices because they are small and low on the food chain, meaning they don’t accumulate high levels of mercury like larger fish (e.g., tuna and swordfish).
Health Benefits of Eating Canned Sardines
Adding sardines to your diet can improve your overall health in many ways. Here’s why:
Boosting Heart Health: Sardines vs. Other Fish
The high omega-3 content in sardines helps lower blood pressure, reduce cholesterol, and decrease the risk of heart attacks. If you’re looking for a heart-healthy food, sardines are one of the best options out there.

Don’t worry! Below are some of the most frequent concerns, along with easy fixes to help you enjoy sardines like a pro.
Strong Fishy Smell: How to Reduce It

How to Choose the Best Quality Canned Sardines
Not all canned sardines are created equal! Here’s what to look for when shopping:

⭐ Look for BPA-free cans – This ensures you’re avoiding harmful chemicals in the can lining.
⭐ Go for wild-caught sardines – They tend to be healthier and more sustainable.
⭐ Check the source – Brands from Portugal, Spain, or the Mediterranean are known for high-quality sardines.
Should You Eat Sardine Bones? Benefits and Risks
Yes, you can eat the bones—and you probably should! The tiny bones in canned sardines are soft and completely edible, providing a rich source of calcium. But if you’re not a fan of the texture, here’s what you can do:
🦴 Mash the sardines with a fork to break down the bones.
🦴 Blend them into spreads, dips, or sauces for a smoother texture.
🦴 Opt for boneless canned sardines if the bones really bother you.
