The overwhelming evidence is that a diet high in common salt (sodium chloride) causes high blood pressure (hypertension) which increases your risk of a number of health conditions.


Studies have linked an abundance of salt in diets to : raised blood pressure (hypertension) causing strokes, heart failure and heart attacks, the leading causes of death and disability in the UK. There is also increasing evidence of a link between high salt intake and stomach cancer, osteoporosis, obesity, kidney stones, kidney disease and vascular dementia and water retention. Salt can also exacerbate the symptoms of asthma, Ménière's disease and diabetes.


Small amounts of salt are essential for our health. Adults need less than 1 gram per day and children need even less. As a nation we are all eating approximately 8.1g of salt per day, far more than we need and more than the  recommended maximum of 6g per day, putting us at risk of all of these health problems. 


Current UK government advice is that adults should consume no more than 6g of salt per day while toddlers (1-3 years) should have no more than 2g.
