No, Why?: Usual systolic BP <120 mmHg correlates with ↓ed rates of cardiovascular events, thus good. All life/food is based on salt water organized by fat (membranes surrounding complex water droplets, i.e. cells) so additional salt not commonly required. Despite marketing, ↑ed NaCl salt intake does Not routinely raise BP. Primary BP control is by brain modulation of cardiac output & peripheral resistance.
