Effect of Dietary Sodium on Blood Pressure

The study by Dr. Gupta and colleagues examined the impact of dietary sodium on blood pressure in adults aged 50 to 75 years. Participants on a high sodium diet showed an 8 mmHg increase in systolic blood pressure compared to those on a low sodium diet. Nearly 75% of individuals experienced reduced systolic blood pressure by limiting dietary sodium intake, irrespective of hypertension or medication use. The findings suggest a spectrum in blood pressure response to sodium intake, supporting policies to reduce sodium in processed foods.
