Deep dives
The Risks of Low Sodium Intake
Consuming less than 3,000 milligrams of sodium per day can significantly increase the levels of stress hormones like insulin, aldosterone, and renin. This hormonal surge can lead to stiffening of the arteries and decreased blood flow, which may ultimately harm kidney function or even cause kidney failure. Notably, cognitive function can also be adversely affected on a low salt diet, resulting in issues such as lack of focus and increased headache frequency. Athletes, who may lose substantial sodium through sweat, are particularly vulnerable to these adverse effects, highlighting the necessity of adequate salt intake.
