Is Low-Sodium Salt a Healthier Choice for Your Family?
If someone at home has high blood pressure, you may have wondered whether changing the salt in your kitchen would help. Perhaps you have noticed packets labelled “low sodium” or heard that pink salt is better than ordinary salt.
The answer depends on what the product contains and who will be eating it. Potassium-enriched salt can be useful for some adults, but it is unsuitable for others. Before changing what goes into the family’s dal and sabzi, it helps to understand the difference.

Why Does Salt Matter for Blood Pressure?
Regular salt contains sodium chloride. Your body needs some sodium, but consuming too much can raise blood pressure and increase the risk of heart disease and stroke.
The difficulty is that you cannot reliably judge your blood pressure by how you feel. You may feel perfectly well despite a high reading.
Reducing excessive sodium is one way to support healthier blood pressure. It works alongside prescribed treatment and other changes to your diet and routine.
How Much Salt Is Too Much?
The World Health Organization recommends that adults consume less than 2,000 mg of sodium a day, equivalent to less than 5 grams of salt, or roughly a level teaspoon.
That is the total from everything you eat. It is not an allowance to add a teaspoon to your meals on top of the sodium already in food.
Think about an ordinary day: salt in breakfast, pickle with lunch, namkeen with tea, and sauces at dinner. Each contributes to the total, even if you rarely reach for the salt shaker.
What Is Different About Low-Sodium Salt?
Many low-sodium salts replace some sodium chloride with potassium chloride. This reduces the sodium in a given quantity while retaining a salty taste.
In its 2025 guideline, WHO conditionally suggested using potassium-containing lower-sodium salt substitutes instead of regular table salt for adults who can safely use them. The recommendation forms part of a wider effort to reduce sodium intake and cardiovascular risk.
It does not mean you can use larger amounts. Check the label, because the proportion of sodium and potassium varies between products.
Who Should Check With a Doctor First?
If you have kidney disease, previously high blood potassium, or a condition that affects potassium removal, do not switch without medical advice.
Your kidneys help regulate potassium. When they cannot remove enough, it can accumulate in the blood and become dangerous.
Medicines matter too. Potassium-enriched salt can be unsuitable with potassium supplements, potassium-sparing diuretics such as spironolactone, and some blood pressure or heart medicines, including ACE inhibitors and angiotensin receptor blockers.
For example, NHS guidance flags potassium-containing salt substitutes as a concern with spironolactone and losartan. Ask your doctor or pharmacist to check your actual medicine list before changing salt.
Think About Everyone Sharing the Meal
A change to the kitchen salt affects more than the person who buys it.
If you cook one meal for children, a pregnant family member or someone with kidney problems, consider their needs before replacing the household supply.
WHO’s recommendation does not extend to children or pregnant women because there is insufficient evidence to make that recommendation. It also excludes people whose ability to remove potassium may be impaired.
This does not establish that these products harm every child or pregnant person. It means the adult recommendation should not be applied to them automatically.
Is Pink Salt or Rock Salt a Better Option?
A different colour or a higher price does not make salt low in sodium. Pink salt, rock salt and sea salt still contribute substantial sodium, so they should not be treated as permission to use more.
Check iodine as well. A speciality salt may not be iodised. WHO recommends that salt consumed should be iodised, while overall intake remains limited.
Make Food Flavourful With Less Salt
You do not have to change every meal overnight. Start with something manageable, such as measuring the salt you add rather than pouring it straight from the container.
Try these everyday adjustments:
- Taste dal or sabzi before adding extra salt.
- Use lemon, garlic, ginger, coriander and spices to build flavour.
- Serve smaller portions of pickle, papad and namkeen.
- Leave extra salt off the dining table.
- Compare packaged foods using sodium values per 100 grams, rather than different serving sizes.
- Check seasoning mixes and sauces before adding more salt to a dish.
Gradual reductions can give your taste preferences time to adjust. Herbs, spices, and less salty snacks are practical ways to begin.
Keep Your Blood Pressure Care on Track
If you already take blood pressure medicine, continue following your prescribed plan. Changing salt does not replace treatment or follow-up.
At your next appointment, bring the packet or a photograph of its ingredients. Ask whether its potassium content is suitable for your health conditions and medicines.
