Can the bones in canned sardines be eaten?

Yes. High-temperature sterilisation softens them completely. They carry most of the calcium in the tin, roughly a third of the recommended daily intake per 100 g serving.

Sardines in oil or in tomato sauce?

In oil for richer flesh and a rounder taste, in tomato sauce for a lighter version ready to serve with rice. Protein and omega-3 content is nearly identical.

How long does an unopened can keep?

Several years at room temperature — the printed date is a best-before, not a use-by. A tin that is swollen, rusted or pierced should be thrown away unopened.

Canned sardines, tuna and preserved vegetables

Canned food plays a particular role on an island: it keeps for years without electricity and cushions supply gaps.

Canned sardines remain the anchor of this aisle. In oil, the flesh is richer and milder; in tomato sauce, it is lighter and pairs straight with rice. Either way, canning preserves the calcium and omega-3, with the bones becoming soft enough to eat.

The aisle also covers tuna, tomato paste and canned vegetables — cupboard staples that make a full meal possible with no cold chain.
