The study from Sweden, involving over 10,000 individuals aged 50-64, revealed a significant connection between dietary salt intake and atherosclerotic lesions in coronary and carotid arteries, irrespective of normal blood pressure. The findings suggest that salt could be a detrimental factor in atherosclerosis development before hypertension. The study utilized coronary computed tomography angiography (CCTA) to assess salt intake's impact on atherosclerosis, highlighting a linear relationship between salt consumption and atherosclerosis in both coronary and carotid arteries. However, this association was negated after adjusting for blood pressure. The study also debunked the "J-curve" theory, showing that very low sodium intake did not increase cardiovascular disease risk. The research emphasizes the importance of limiting salt intake to prevent atherosclerosis, even with normal blood pressure.
