The scare around sodium began gaining traction in 1977 when dietary goals for the United States warned against excessive salt intake, limiting it to a mere 5 grams per day. This recommendation was rooted in studies that often lacked robust human trials, with significant findings coming decades later. Notably, Dr. Lewis Dahl’s research in the 1960s, which suggested a correlation between high salt intake and hypertension, was based on rodent studies, and its relevance to human health remained largely unassessed until the mid-1980s.
