In middle-aged adults in East Jakarta, eating too much salt does not show a clear link to high blood pressure, even though most people in the group consume more than recommended amounts.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether sodium intake above 2,000 mg/day increases hypertension risk in middle-aged adults in urban Southeast Asian populations, accounting for potassium intake and sodium-potassium ratio.
A systematic review and meta-analysis of randomized controlled trials and prospective cohorts in adults aged 40–60 from urban Southeast Asia, comparing hypertension incidence across sodium intake quartiles (≤1,500, 1,501–2,000, 2,001–3,000, >3,000 mg/day), adjusting for potassium intake, BMI, and physical activity.
Whether reducing sodium intake from >3,000 mg/day to <2,000 mg/day lowers blood pressure in this demographic, independent of potassium changes.
A double-blind RCT of 250 adults aged 40–60 in East Jakarta with baseline sodium intake >3,000 mg/day and BP ≥130/85 mmHg, randomized to low-sodium diet (<2,000 mg/day) with potassium-matched placebo or usual diet, measuring 24-hour ambulatory BP over 16 weeks.
Whether individuals with consistently high sodium intake develop hypertension at higher rates than those with low intake, after adjusting for potassium and sleep.
A prospective cohort study following 1,200 adults aged 40–60 in East Jakarta for 5 years, measuring sodium intake via repeated 24-hour recalls and tracking incident hypertension, adjusting for potassium intake, sleep duration, BMI, and stress.
Whether individuals with hypertension had higher sodium intake in the years before diagnosis compared to controls.
A matched case-control study comparing 200 adults with newly diagnosed hypertension to 200 controls, retrospectively assessing sodium intake over the prior 3 years using validated food frequency questionnaires and urinary sodium excretion.
Whether sodium intake and hypertension status co-occur in a population at a single point in time.
A population-based survey measuring sodium intake via 24-hour recall and blood pressure in 1,000 adults aged 40–60 in East Jakarta, as performed in this study.
