Real food can come in a can

Processing is not a guilty verdict

Canning uses heat and a sealed container to make food safe and shelf-stable. That is processing. So are freezing, fermenting, cooking and drying. The useful question is what the process leaves you with.

A can of tomatoes is still recognisably tomatoes. Chickpeas are still chickpeas. Sardines still provide fish rather than a reconstituted seafood-flavoured snack. The Australian Dietary Guidelines explicitly include canned vegetables and legumes alongside fresh, frozen and dried forms.

A steel can is packaging. It is not proof that the food inside has been rebuilt from flavour, starch and marketing.

Read for salt, sauce and the stuff riding along

The ingredient list still matters. Compare plain beans with beans swimming in sweet sauce, tuna in springwater with a flavoured lunch kit, and tomatoes with no added salt against a heavily seasoned pasta base. Similar cans can do very different jobs.

Choose no-added-salt or lower-sodium versions where available. Drain foods packed in brine and rinse beans and lentils under water. FSANZ notes that washing and draining can change how much sodium remains, which is exactly why the simple sink step is worth doing.

Convenience can help real cooking happen

Legumes bring fibre and plant protein, but dried versions need planning. Canned chickpeas and lentils can move a curry, soup, salad or bolognese from good intention to dinner in minutes. Monash FODMAP also notes that some water-soluble oligosaccharides leach into canning liquid, so draining and rinsing can make suitable portions easier for some people following a low FODMAP approach.

Keep a few useful cans in the pantry: tomatoes, chickpeas, lentils, beans and fish you genuinely like. Pair them with vegetables, herbs, eggs, wholegrains or good bread. Cooking from real ingredients does not require performing every preservation step yourself.
