[78]. There are many inherent limitations of such analyses. Messerli et al. [78] correlate sodium and outcomes by country, not by individual. The study design is unable to remove unmeasured confounding (ecological fallacy), a well-known methodological concern that the authors acknowledge and then promptly dismiss. Many countries do not have data on sodium intake and, when available, it is often of poor quality. When comparing “high income” countries (in World Bank Income Class 1), the authors aggregate data from the USA, UK and Canada, Trinidad & Tobago, and Equatorial Guinea. The distribution of wealth in these countries and the ensuing disparities in individual health will have huge effects on life expectancy due to factors other than sodium intake, none of which are accounted for. In addition, Messerli et al. ignore the hard evidence from previous human trials. Yet, Messerli et al. claim their results “argue against dietary sodium intake being a culprit of curtailing life span or being a risk factor for premature death”. from: https://link.springer.com/article/10.1007/s13668-021-00383-z https://link.springer.com/article/10.1007/s13668-021-00383-z
