Many carbonated mineral waters may contain high levels of salt
And drinking large amounts daily can contribute to unhealthy salt levels and make you more thirsty. Tap water contains only 0.45g of salt per litre compared to luxury mineral brands, some of which are the worst offenders:
- French Badoit contains 8 per cent of the recommended daily intake (RDI) of salt for adults, with 0.45g per litre. It’s 11 times saltier than tap water.
- Italian brand San Pellegrino has double the amount of salt found in tap water, with 0.08g per litre
- Buxton sparkling water contains 0.06g per litre – one and a half times the salt in tap water.
- Spa Barisart and Highland Spring are two of the least salty on the market, with just 0.01g of salt per litre, a quarter of the amount found in tap water.
Consuming too much salt can cause a number of health problems including raising blood pressure, increasing the risk of heart disease and stroke, and kidney problems.
In the UK the recommended maximum daily consumption of salt is 6g. But consumers can be confused by the different names given to salt such as sodium or the chemical name Na.
Although the British Soft Drinks Federation says new guidelines will ensure that salt is called salt in drinks from December.
