The American Heart Association has told us for decades that eating too much salt will increase the risk of high blood pressure and cardiovascular disease and that we should dramatically limit our salt intake as a result. In fact, they suggest limiting sodium intake to a maximum of 2,300 mg a day, with an “ideal limit” of 1,500 mg/d.

In this video, I share the latest research on sodium intake and cardiovascular disease and explain why the American Heart Association’s recommended limits are misguided. I also explain the downsides of excessive salt restriction and tell you why we need a moderate amount of sodium to be healthy.

Here's what we'll cover in this video:
› 00:00 — Current Sodium Intake Recommendations
› 00:54 — What the Research on High- and Low-Salt Consumption Shows
› 02:46 — The Risks Associated with a Low-Salt Diet
› 04:20 — The Role of Sodium in the Body and its Significance
› 06:02 — When Does Salt Restriction Make Sense?
› 08:24 — The Relevance of Potassium and Other Nutrients
