I stood in the grocery store holding two cans of sardines.
One cost less than two dollars.
The other was almost twice the price.
They looked nearly identical.
So I asked my doctor if there was really any difference.
He smiled and said,
“Sardines are one of the healthiest fish you can eat, but not every canned product is the same. The ingredients, sodium content, packing liquid, and sustainability can vary quite a bit.”
That advice changed the way I shop for canned seafood.
Why Sardines Are So Healthy
Sardines are naturally rich in:
- Heart-healthy omega-3 fats
- High-quality protein
- Vitamin D
- Vitamin B12
- Calcium (when you eat the soft bones)
- Selenium
They’re also relatively low in mercury compared with many larger fish because they are small and lower on the food chain.
Instead of focusing on avoiding specific brands, it’s often more helpful to know what makes one can a better choice than another.
5 Things to Check Before Buying Canned Sardines
1. Choose Sardines Packed in Olive Oil or Water
Sardines packed in extra virgin olive oil or water are often a better choice than those packed in heavily refined oils or sugary sauces.
2. Compare the Sodium
Some canned sardines contain more than 400–500 mg of sodium per serving, while others contain much less.
If you’re watching your blood pressure, look for lower-sodium options whenever possible.
3. Read the Ingredient List
The best cans usually have only a few ingredients:
- Sardines
- Olive oil or water
- Salt
Short ingredient lists are often a good sign.
4. Look for Sustainability Labels
Certifications from reputable sustainable fisheries can indicate responsible fishing practices.
5. Check the Nutrition Label
Look for products that provide:
- High protein
- Omega-3 fats
- Calcium
- Vitamin D
These nutrients make sardines one of the most nutrient-dense seafood choices available.
Three Types of Sardines Worth Looking For
Rather than worrying about viral lists claiming certain brands are “bad,” many nutrition professionals recommend choosing sardines that have these characteristics:
✓ Wild-Caught Sardines in Extra Virgin Olive Oil
Excellent for healthy fats and rich flavor.
✓ Wild-Caught Sardines Packed in Water
A great option for people limiting calories or fat.
✓ Lower-Sodium Sardines
Ideal for individuals trying to reduce their daily sodium intake.
