Well there you have it, salt really is bad for you – based on a study of 107 randomised comparisons on the effects of reduced sodium intake on blood pressure, 99 cohorts on the effects of blood pressure on cardiovascular mortality, and a survey of the salt intake of three-quarters of all adults in the world. It is hard to argue with the results of a study like that. Modelling based on the data from the above study, funded by the Bill and Melinda Gates Foundation, concludes that one in every ten deaths from cardiovascular disease can be attributed to a high salt intake. Incidentally, having 107 randomised comparisons makes it possible to examine the correlation between the reduction of salt intake in those trials, and the reduction in blood pressure. It turns out to be linear.
