How Do You Reduce the Excess Salt in Canned Food?

The simplest way to cut the salt in canned food is to drain the liquid and rinse the contents under cold running water in a colander for 30 to 60 seconds; this washes away a large share of the surface salt. For very salty items like olives or anchovies, if rinsing alone isn't enough, soaking briefly in fresh water and changing it once works better.

Why is canned food so salty in the first place?

Salt plays both a flavour and a preservative role in canning; it slows bacterial growth and extends shelf life. That's why brined olives, pickles, anchovies and some canned vegetables carry a noticeably higher salt level than their home-cooked equivalents.

The label on the can states sodium content per serving; low-salt or no-added-salt versions of the same product usually sit right next to the regular one on the shelf, and are a better starting point for anyone watching their intake.

Rinsing and soaking

For canned chickpeas, corn or beans it's enough to drain them first and then rinse under cold running water for 30 to 60 seconds; this short step removes a meaningful share of the salt. For oily cans like tuna, pressing lightly with a fork after draining lets some of the remaining salt run off with the oil.

For products where salt has really soaked in, like olives or anchovies, a single rinse may not be enough; soaking for 10 to 15 minutes in fresh water and changing it once cuts the saltiness more noticeably.

Keeping the flavour balanced once you cut the salt

Tasting rinsed canned food before adding any extra salt to a dish shows whether it's still salty enough on its own; rinsed canned food usually doesn't need more. Boosting flavour with vinegar, lemon juice or fresh herbs balances out the flatness that can appear once the salt drops.

For people watching their blood pressure or sodium intake, this rinsing step, done consistently, can make a real difference to daily salt intake; if salt restriction is a serious medical concern though, a doctor's or dietitian's guidance should come first.

Which canned foods carry the most salt?

Olives, anchovies, pickles and some brined cheeses sit among the saltiest canned and jarred products, since in these salt isn't just for flavour but also helps preserve texture and colour. Canned vegetables and pulses generally carry a lower salt level, and rinsing alone is usually enough for them.

Canned soups and ready-made sauces can pack a large share of the recommended daily sodium into a single can; since rinsing isn't an option there, checking the sodium figure on the label and choosing a low-salt version is the more effective fix.

Adjusting the salt level from the start is easier in home-made pickles and preserves than rinsing a store-bought can afterwards; anyone wanting less salt in a home batch can simply change the recipe itself. With a shop-bought can, that option doesn't exist, so rinsing remains the one practical fix. Even this small difference can noticeably affect daily salt intake over time.
