What Are Sardines? An Introduction
Sardines, also known as pilchards in some regions, are a family of small, oily fish. They’re a popular food source around the world, appreciated for their flavor, nutritional value, and affordability. But are canned sardines real fish? The simple answer is yes.

- Packing: The sardines are carefully packed into cans, often with olive oil, water, or sauces.
- Sealing: The cans are hermetically sealed to prevent spoilage.

Frequently Asked Questions (FAQs)
Are canned sardines real fish or some kind of processed fish paste?

Are sardines considered a healthy food choice?
Yes, sardines are considered a very healthy food choice. They are packed with omega-3 fatty acids, vitamin D, calcium, and protein. Their nutritional profile makes them an excellent addition to a balanced diet.
Do canned sardines contain bones?
