The Claim
Observational studies indicate a J-shaped association between sodium intake and cardiovascular mortality, such that both very low and very high levels of sodium intake are associated with increased risk of cardiovascular death.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Too little or too much salt might both be bad for your heart — studies show people who eat way too little or way too much salt may be more likely to die from heart problems.
See the scientific wording
Observational studies suggest a J-shaped association between sodium intake and cardiovascular mortality, meaning both very low and very high intake may be linked to higher risk.
What the research says
1 studyStudy: Recommendations on sodium intake for cardiovascular health: conviction or evidence?
This study says that eating too little or too much salt might both be bad for your heart, which matches the claim that there’s a 'J-shaped' risk pattern — not too little, not too much, just right.
