What Are Sardines?
Sardines, also known as pilchards in some regions, are small, oily fish that belong to the herring family, Clupeidae. These fish are widely found in both the Atlantic and Pacific Oceans and are named after the Mediterranean island of Sardinia, where they were once abundant. Sardines are typically 6–12 inches long and are characterized by their silver-colored bodies and oily texture.
These fish are often consumed whole, including their bones and skin, which are soft and edible. Sardines are usually sold fresh, smoked, or canned in oil, water, or tomato sauce. Their mild yet distinct flavor makes them a popular ingredient in various cuisines around the world, from Mediterranean to Asian dishes.
In addition to their culinary appeal, sardines are prized for their incredible nutritional value. Their low position on the food chain and short lifespan mean they accumulate fewer toxins, such as mercury and polychlorinated biphenyls (PCBs), compared to larger predatory fish. This makes them a safer and healthier choice for regular consumption.
