The Claim
Both very low sodium intake (<3,000 mg/day) and very high sodium intake (>6,000 mg/day) are associated with an increased risk of cardiovascular events and mortality, indicating a J-shaped relationship between sodium intake and cardiovascular outcomes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating too little or too much salt might both be bad for your heart — people who eat way less than 3,000 mg or way more than 6,000 mg of salt a day seem to have a higher chance of heart problems or dying from them.
See the scientific wording
Both very low (<3,000 mg/day) and very high (>6,000 mg/day) sodium intake are associated with increased risk of cardiovascular events and mortality, suggesting a J-shaped relationship.
What the research says
2 studiesStudy: Urinary sodium and potassium excretion, mortality, and cardiovascular events.
This study found that people who eat too little salt (<3 grams a day) or too much salt (>6 grams a day) are more likely to have heart problems or die, but those who eat a moderate amount (3–6 grams) are healthiest — just like a J-shaped curve.
This study found that people with heart disease who ate too little or too much salt had a higher risk of heart problems or dying, with the safest amount being in the middle — which matches the claim that both very low and very high salt intake are dangerous.
