“I eat a mountain of salt… and my blood pressure is normal.”
No, not genetics — metabolic context.
Sodium is essential. Whether salt helps or harms depends on your metabolic state. If you’re lean and insulin-sensitive, hormones like leptin (from fat tissue) and neural/kidney signaling can handle sodium very differently than in insulin resistance or obesity.
In this short, Nick Norwitz MD PhD explains why salt isn’t “good” or “bad” in isolation, and why individual context (metabolic health, body composition, history, meds) should shape your approach.
