> But high salt diets aren’t in and of themselves a problem. You are directly contradicting my link: > In 2019, a diet high in sodium was responsible for 44·9 million (95% UI 13·0–94·7) DALYs and 1·89 million (0·477–4·19) deaths. It was the leading dietary risk factor for attributable DALYs. https://www.healthdata.org/results/gbd_summaries/2019/diet-high-in-sodium-level-3-risk https://www.healthdata.org/results/gbd_summaries/2019/diet-h...

Your one paper is based on on study using health and diet surveys. A comprehensive review of the literature found that: "When reviewing the evidence for an upper level of 5.8 g/day, it becomes apparent that neither the supporting studies selected by the health institutions, nor randomized controlled trials and prospective observational studies disregarded by the health institutions, document that a salt intake below this 5.8 g, has beneficial health effects. Although there is an association between salt intake and blood pressure, both in randomized controlled trials and in observational studies, this association is weak, especially in non-obese individuals with normal blood pressure. Furthermore a salt intake below 5.8 g is associated with the activation of the renin-angiotensin-aldosteron system, an increase in plasma lipids and increased mortality." https://www.sciencedirect.com/science/article/pii/S0033062018300835 https://www.sciencedirect.com/science/article/pii/S003306201...

  Interesting! From the study: Fig. 3. shows normotensive studies plotted with blood pressure on the Y-axis. So, if you have normal blood pressure, reducing salt won't reduce it further. Am I getting it right? According to data here, 46 percent of US adults has B.P. at least 130 systolic or 80 diastolic, and 32 percent have >= 140 systolic or 90 diastolic. https://newsroom.heart.org/news/high-blood-pressure-redefined-for-first-time-in-14-years-130-is-the-new-high https://newsroom.heart.org/news/high-blood-pressure-redefine... The Sacks study in the paper you linked (ref 15) shown in Fig 1 shows a strong benefit for people with 130 systolic.

    Generally if you have some sodium-sensitive hypertension, then yes, restricting salt can be helpful. But most people's bodies deal with excess salt without problem or impact on blood pressure.
