Salt substitute
A salt substitute, also known as low-sodium salt, is a low-sodium alternative to edible salt (table salt) marketed to reduce the risk of high blood pressure and cardiovascular disease associated with a high intake of sodium chloride while maintaining a similar taste.
The leading salt substitutes are non-sodium table salts, which have their tastes as a result of compounds other than sodium chloride. Non-sodium salts reduce daily sodium intake and reduce the health effects of this element.
A low sodium diet is a diet that includes no more than 1,500 to 2,400 mg of sodium per day.
The human minimum requirement for sodium in the diet is about 500 mg per day, which is typically less than one-sixth as much as many diets "seasoned to taste". For certain people with salt-sensitive blood pressure or diseases such as Ménière's disease, this extra intake may cause a negative effect on health.
In 2021, a large randomised controlled trial of 20,995 older people in China reported that use of a potassium salt substitute in home cooking over a five-year period reduced the risk of stroke by 14%, major cardiovascular events by 13% and all-cause mortality by 12% compared to use of regular table salt. The study reported no significant difference in hyperkalaemia between the two groups, though people with serious kidney disease were excluded from the trial. The salt substitute used was 25% potassium chloride and 75% sodium chloride.
A 2022 Cochrane review of 26 trials involving salt substitutes reported their use probably slightly reduces blood pressure, non-fatal stroke, non-fatal acute coronary syndrome and heart disease death in adults compared to use of regular table salt. A separate systematic review and meta-analysis published in the same year of 21 trials involving salt substitutes reported protective effects of salt substitute on total mortality, cardiovascular mortality and cardiovascular events.
A 2023 clinical trial engaged 1,612 residents of 48 residential care facilities in China. They were cluster-randomized via a 2 × 2 factorial design substituting 62.5% NaCl/25% KCl versus usual salt and progressively restricted versus usual supply for 2 years. The substitute lowered systolic blood pressure (–7.1 mmHg, 95% confidence interval (CI) –10.5 to –3.8), meeting the primary endpoint, whereas restricted vs usual supply had no effect. Substitute lowered diastolic blood pressure (–1.9 mmHg, 95% CI –3.6 to –0.2) and resulted in fewer cardiovascular events (hazard ratio (HR) 0.60, 95% CI 0.38–0.96), but had no effect on total mortality.
Potassium closely resembles the saltiness of sodium. In practice, potassium chloride (also known as potassium salt) is the most commonly used salt substitute. Its toxicity for a healthy person is approximately equal to that of table salt (the LD50 is about 2.5 g/kg, or approximately 190 g (6.7 oz) for a person weighing 75 kg (165 lb).[medical citation needed] Potassium lactate may also be used to reduce sodium levels in food products and is commonly used in meat and poultry products. The recommended daily allowance of potassium is higher than that for sodium, yet a typical person consumes less potassium than sodium in a given day. Potassium chloride has a bitter aftertaste when used in higher proportions, which consumers may find unpalatable. As a result, some formulations only replace half the sodium chloride with potassium.
