Long-term adherence to a sodium reduction intervention significantly reduces the risk of major cardiovascular events (myocardial infarction, stroke, revascularization, or cardiovascular death) in adults with prehypertension.
If you have high-normal blood pressure, reducing your sodium intake through counseling and dietary changes can significantly lower your risk of heart attacks, strokes, and cardiovascular death over the next 10-15 years. Focus on identifying sodium sources and preparing lower-sodium meals; your taste buds will likely adapt, making it easier to maintain.
Risk of a cardiovascular event was 25% lower among those in the intervention group (relative risk 0.75, 95% confidence interval 0.57 to 0.99, P=0.04)... Sodium reduction, previously shown to lower blood pressure, may also reduce long term risk of cardiovascular events.
Why this rating
Randomized controlled trials with long-term observational follow-up (10-15 years) provide strong evidence, though the follow-up was observational.

- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
