How to cut your sodium without your food tasting like cardboard
Put the salt shaker down last, not first. A normal breakfast and lunch can pass the World Health Organization's whole-day sodium target before anyone seasons anything. On real Dietly labels, two slices of ordinary white bread carry about 389 mg of sodium, 30 g of cheddar 230 mg, and a 300 g bowl of tinned tomato soup 1,200 mg. That is 1,819 mg from three unremarkable items against a 2,000 mg daily target. The shaker on your table is a rounding error next to the bread bin, the cheese drawer and the sauce shelf, which is good news: it means the changes that work are boring purchasing decisions rather than a flavourless diet.
| Dietly label | Sodium per 100 g | Realistic portion | Sodium in that portion |
|---|---|---|---|
| Soy sauce | 6,760 mg | 1 tbsp, 18 g | 1,217 mg |
| Back bacon | 1,467 mg | 2 rashers, 50 g | 734 mg |
| Veggie straws | 929 mg | small bag, 30 g | 279 mg |
| Cheddar | 767 mg | 2 slices, 30 g | 230 mg |
| Ketchup | 720 mg | 1 tbsp, 15 g | 108 mg |
| Smoked ham | 622 mg | 3 slices, 50 g | 311 mg |
| White bread | 486 mg | 2 slices, 80 g | 389 mg |
| Tinned tomato soup | 400 mg | 1 bowl, 300 g | 1,200 mg |
Step 1: find out where yours actually comes from
Population surveys consistently put most sodium intake in processed and prepared foods rather than in cooking or table salt, and the exact mix differs by country and by household. A survey of Australian adults, for example, traced the majority of intake to bread, processed meat, cheese, sauces and ready meals. Your own mix is knowable in one week: log normally, change nothing, then sort by sodium. Almost everyone finds the same shape, which is three or four repeat items doing most of the damage because they appear every day, not because any one of them is extreme.
Step 2: fix the highest-frequency item first, by brand
Bread is the classic example. Nobody thinks of it as salty, and in our data it runs from about 10 mg to 543 mg of sodium per 100 g depending on the loaf. Two slices a day of the high end versus the low end is a difference of roughly 380 mg a day, or a fifth of the whole target, from a change nobody tastes. The same logic applies to the cheese you buy weekly and the stock you cook with. This is the single highest-yield move available, because it changes an amount you eat every day without changing what you eat. Scan the loaf you buy into the comparison tool against one other brand and you have the answer in a few seconds.
Step 3: measure the things you pour
Sauces are where estimation fails hardest, because their per-100 g figures are enormous and the amounts feel small. One tablespoon of soy sauce is 1,217 mg of sodium, which is 61% of a whole day in a splash. Two tablespoons over a stir-fry for one is a day and a quarter. You do not have to stop using it; you have to stop free-pouring it. Measure it once, look at what a tablespoon actually is, and use a teaspoon and more aromatics thereafter. Reduced-salt soy sauces exist and typically cut the figure by 30 to 40%, which is a real improvement on a real amount.
Step 4: treat cured meat as the density leader that it is
Cured and processed meats are salt-preserved by definition, which is why back bacon reads 1,467 mg per 100 g and smoked ham 622 mg. A sandwich built from ham, cheese and bread is close to 900 mg before any condiment. Nothing here says never eat a bacon sandwich. It says that if your sodium is high and you eat cured meat most days, this is the second lever after bread, and swapping to roast chicken or leftover cooked meat on two of those days moves more sodium than a month of shaker discipline.
Step 5: replace salt with acid, aromatics and umami
The reason low-sodium cooking gets a reputation for tasting like cardboard is that people remove salt and add nothing. Salt does two jobs: it tastes salty and it makes other flavours louder. The second job has substitutes. Acid, from lemon, lime or vinegar, sharpens a dish in a way that reads as seasoning. Aromatics such as garlic, onion, chilli, black pepper, mustard and fresh herbs add complexity that distracts from the missing salt. Umami ingredients, including tomato paste, dried mushrooms and a small amount of parmesan, add savoury depth per gram far more efficiently than salt does. Toast your spices. Finish with something fresh. None of this is a sacrifice, and most of it makes better food than the salt-only version.
Step 6: give your palate two to three months
Salt preference is learned and it moves. Controlled work going back decades shows that people who reduce dietary salt shift their preferred concentration downwards over a matter of weeks, and a 2018 trial found that children accepted bread with substantially reduced salt without rating it worse. The practical implication is that the first fortnight is the worst it will ever taste. Cut gradually, hold the new level, and food that tasted flat in week one tastes normal by week eight, at which point the old version tastes aggressively salty. Trying to do it in one weekend is what makes people quit.
What not to bother with
- Banning the shaker on day one. Table and cooking salt is the minority of intake for most people, and in countries with iodised salt it is a meaningful iodine source. Change it last.
- Pink, sea or flaky salt as a health swap. These are sodium chloride with different crystal sizes and trace minerals. If a flakier salt makes you use less by volume, that is the entire benefit.
- Chasing zero. Sodium is an essential electrolyte, and the target is moderation, not elimination. The electrolytes explainer covers where the floor is.
- Assuming savoury means salty. Some sweet products carry real sodium, and some savoury snacks carry less than their reputation. Check, do not guess.
A worked day
Two slices of the high-sodium white bread at 389 mg, 30 g of cheddar at 230 mg, a bowl of tinned soup at 1,200 mg and two rashers of bacon at 734 mg add up to 2,553 mg, or 128% of the WHO daily target, with no shaker involved and no meal anyone would call salty. Swap the soup for a homemade one, move the bacon to the weekend, and the same day lands close to 1,000 mg while still containing bread, cheese and a hot lunch. That is what a realistic sodium reduction looks like: four purchasing decisions, not a diet. To check where your own staples sit, look up each one and read the sodium row, or convert the salt figure with the sodium vs salt guide.

Common questions
How much sodium should I eat per day?
The World Health Organization recommends less than 2,000 mg of sodium a day for adults, which is about 5 g of salt. On real labels that budget is easy to pass without seasoning anything: bread, cheese and a bowl of tinned soup alone come to roughly 1,819 mg.
Where does most dietary sodium come from?
Not the shaker. Population surveys consistently put the majority in processed and prepared foods, led by bread, cured meat, cheese, sauces and ready meals, because those are eaten daily rather than because any single one is extreme.
Is sea salt or pink salt lower in sodium?
No. They are sodium chloride with different crystal sizes and trace minerals. The only real effect is that a flakier crystal means less sodium per spoonful by volume, so you may use less without noticing.
How long until low-salt food stops tasting bland?
Roughly eight to twelve weeks. Salt preference is learned and shifts downward when intake falls, which is why gradual reduction works and an abrupt cut usually fails in the first fortnight.
