The Claim
Chronic activation of the renin-angiotensin-aldosterone system (RAAS) in response to very low sodium intake increases vascular resistance and contributes to cardiovascular pathology.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
When you eat almost no salt, your body may overwork a system that controls blood pressure, making your blood vessels tighter and raising your risk of heart problems.
See the scientific wording
Chronic activation of the renin-angiotensin-aldosterone system (RAAS) in response to very low sodium intake may increase vascular resistance and contribute to cardiovascular pathology.
What the research says
1 studyThe study found that eating less salt lowers blood pressure and reduces heart disease risk, which is the opposite of what the claim says — the claim thinks very low salt makes your blood vessels tighter and harms your heart, but the data shows the opposite.
