The research, conducted by Wits University and Harvard, highlights the potential of such policies to curb cardiovascular diseases, which claim 20 million lives annually worldwide.<\/p>\n\n\n\n<p>The study, titled\u00a0<em>Sodium Reduction Legislation and Urinary Sodium and Blood Pressure in South Africa<\/em>, analyzed data from over 5,000 adults aged 40 and above in rural South Africa. Participants reduced their sodium intake by 10% over seven years, with the proportion meeting ideal sodium consumption levels rising from 7% to 17%.<\/p>\n\n\n\n<p>South Africa\u2019s legislation targeted 13 food categories, including bread, cereals, and processed meats, mandating sodium reductions of 20\u201370% by 2016 and further cuts of 5\u201346% by 2019. Professor Steve Tollman, a co-author, emphasized that stricter regulations outperform voluntary measures, noting, \u201cThis study demonstrates that government action with accountability can impact both sodium intake and blood pressure.\u201d<\/p>\n\n\n\n<p>Associate Professor Thomas Gaziano of Harvard added that even a 1 mmHg drop in blood pressure could prevent tens of thousands of deaths annually.
