Do you have a ‘salt tooth’? How to recognise it – and feed your cravings healthily

We all know what a sweet tooth is, but some people also hanker for salt. Here’s what to do if you can’t stop dreaming of crisps

Is there any such thing as a “salt tooth”? We are familiar with a sweet tooth, and sugar cravings, along with the negative effects of those. We are broadly aware of the downsides of too much salt, including high blood pressure, which puts pressure on the blood vessels, the heart and the kidneys. It can also lead to water retention. The British Heart Foundation concluded last year that if everyone brought their consumption down to the World Health Organization salt limit of 5g a day by 2030, the result would be up to 1.4m fewer new cases of high blood pressure, 135,000 fewer new cases of coronary heart disease, up to 49,000 fewer new cases of stroke and more than 450,000 extra years in good health.

But salt is not considered a dietary luxury, even though 40% of people, according to a YouGov poll, would put crisps way above chocolate in the treat hierarchy. We don’t tend to police how much we eat – at least, not as rigorously as with sugar – or question whether we are innocently listening to our bodies, which need some salt for basic muscle function, or are in the grip of a compulsion.
