Canned sardines have everything going for them: they're convenient, economical, and packed with nutrients. However, a few seemingly harmless habits can diminish their benefits, or even make them less nutritious than they appear. Here are five essential points to know to enjoy these small fish with peace of mind and get the most out of their nutritional value.
Not all canned sardines are created equal.
It's often assumed that buying canned sardines automatically guarantees a healthy and nutritious product. However, the reality is far more nuanced. Quality varies considerably from one brand to another. Some manufacturers use fish processed quickly after being caught, while others are far less scrupulous. From the moment you open the can, certain clues reveal everything: a metallic smell, completely flaky flesh, or a liquid with a questionable appearance. These signals indicate poor quality and, consequently, reduced nutritional value. Take the time to decipher the labels before you buy.
Why you should always drain the liquid from the can
Here's a simple step almost everyone forgets: rinse and drain sardines before eating them. The canning liquid often contains a significant amount of salt, residues from the sterilization process, and oils that may have oxidized. Regular consumption of this liquid promotes water retention and can insidiously raise blood pressure. A simple pass through a colander is all it takes to preserve most of their nutritional value. A small step, but truly crucial for your health.
