Learning how to reduce salt in your everyday diet starts with a fact that reframes the whole approach: the WHO recommends less than 5 grams of salt a day — about 2 grams of sodium, just under a teaspoon — while the global average intake more than doubles that figure. Most of that excess doesn’t come from the salt shaker in your kitchen; it comes from the processed foods you buy every week.

Why Putting Away the Salt Shaker Isn’t Enough
Almost everyone who decides to «eat less salt» does the same thing: removes the salt shaker from the table. Then they’re surprised when it barely changes their test results or their blood pressure.
The reason lies in where the salt actually comes from. According to PAHO, in many countries, three-quarters of dietary sodium comes from processed foods: bread, processed cereals and grains, processed meats, cheeses, salty snacks, sauces, dressings, and cold cuts.
In other words, the salt shaker is the small part of the problem. The big part is sitting in the supermarket cart, not on the table.
How Much Salt Is Recommended, According to the Evidence
| Reference | Amount |
|---|---|
| WHO recommendation (adults) | Less than 5 g of salt a day (under 2,000 mg of sodium). |
| Practical equivalent | Just under a level teaspoon. |
| Estimated global average intake | Around 10.8 g of salt a day. |
| In the Americas | The WHO estimates an average intake of about 8.5 g a day in adults. |
In other words, the world consumes, on average, roughly double the recommended amount.
The WHO estimates that millions of deaths a year could be avoided if salt consumption dropped to the recommended level, since excess sodium is linked to higher blood pressure, which is in turn a major cardiovascular risk factor.
Here’s a note about children: the WHO recommends adjusting the adult amount downward for children ages 2 to 15, based on their specific energy needs.
Where Sodium Is Actually Hiding in Your Diet
These are the foods that contribute the most sodium in a typical diet, many of them without tasting especially salty at first bite:
- Bread and bakery products. Because of how much people eat daily, this is often one of the top sodium sources in the entire diet.
- Cold cuts, deli meats, and processed meats.
- Cheese, especially aged and processed cheese.
- Salty snacks and bagged appetizers.
- Sauces and dressings: soy sauce, ketchup, mustard, salad dressings.
- Bouillon cubes and instant soups.
- Brined preserves: olives, pickles, oil-packed tuna with added salt.
- Fast food and pre-cooked meals.
- Breakfast cereals. Yes, even the sweet ones have added sodium.
How to Read Salt on a Product Label
Here’s a very common point of confusion worth clearing up: salt and sodium aren’t exactly the same thing.
The conversion: multiply grams of sodium by 2.5 to get the equivalent grams of salt. A product with 0.8 g of sodium per 100 g actually has 2 g of salt per 100 g.
Here are useful benchmarks for judging any product, per 100 grams:
| Salt Content | Assessment |
|---|---|
| 1.25 g or more | Very high content. |
| Around 0.25 g | Low content. |
And if your country uses front-of-package warning octagons, the «high in sodium» seal does that calculation for you directly.
How to Reduce Salt Without Losing Flavor in Your Meals
This is the point that decides whether the change lasts over time or not. Salt shouldn’t just be removed — it should be replaced with other ways of adding flavor to food.
1. Acids. Lemon, lime, vinegar. These enhance flavor and reduce the need for salt quite surprisingly.
2. Herbs and spices. Cumin, oregano, chili, pepper, garlic, onion, bay leaf, rosemary, cilantro, parsley, ginger.
3. Cooking techniques. Browning, roasting, and caramelizing concentrate the natural flavor of food without needing to add anything else.
4. Add salt at the end of cooking. Salt added at the end is more noticeable on the palate, so you need less of it to achieve the same effect.
5. Reduce gradually. Your palate adapts within a matter of weeks. Lower the amount little by little, and you’ll barely notice it.
6. Rinse canned goods. Draining and rinsing canned legumes or tuna removes a significant portion of the sodium from the canning liquid.
7. Cook more at home. This is the single most effective step of all, since it hands you back control over the biggest source of sodium in your diet.
As for potassium-based salt substitutes, the WHO recommends that, if table salt is used at all, it be replaced with low-sodium salts containing potassium. Be careful, though: these aren’t suitable for everyone, especially people with kidney disease or those taking certain medications. Always check with your doctor before starting to use them.
Key Takeaways
- Knowing how to reduce salt starts with understanding that the WHO recommends less than 5 g a day, about 2 g of sodium.
- The global average intake is around 10.8 g — more than double the recommended amount.
- Three-quarters of dietary sodium comes from processed foods, not the salt shaker on the table.
- Sodium multiplied by 2.5 equals salt — that’s the conversion you need when reading any label.
- Bread is often one of the biggest sodium sources, simply because of how much people eat daily.
- Replace salt with acids, herbs, and spices, and reduce it gradually, never all at once.
Frequently Asked Questions
These are the most common questions about how to reduce salt in everyday life.
Are sea salt or pink salt better than regular table salt? Their sodium content is practically identical across the board. The differences in trace minerals are minimal and don’t change the general consumption recommendation at all.
How long does it take for your palate to get used to less salt? Most people notice the change within a few weeks if the reduction happens gradually. What used to taste good over time starts tasting overly salty.
Do athletes need more salt than everyone else? During intense, prolonged effort with heavy sweating, sodium losses increase and need to be replaced appropriately. That’s a specific, situational case, not a general rule for everyone.
Can I use light or potassium-based salt in my meals? The WHO presents this as a valid option, but it isn’t suitable for everyone, especially people with kidney problems or those taking certain medications. Always check with your doctor first.
