INSIGHT

Sodium Potassium Ratio Predicts Cardiovascular Risk

  • High blood pressure risk depends on the sodium to potassium ratio rather than sodium alone.
  • Harvard analysis of 10,000+ adults showed +1000 mg sodium increased and +1000 mg potassium decreased cardiovascular risk by 18% each.
INSIGHT

Potassium Buffers Sodium Effects On Blood Pressure

  • The sodium-potassium balance is more predictive than absolute sodium; higher potassium lets you tolerate more sodium.
  • Dr. Eric Berg notes typical sodium need ~2,400 mg and potassium buffers sodium's effect on blood pressure.
ADVICE

Increase Dietary Potassium Toward 4,700 Mg

  • Increase potassium intake toward the 4,700 mg daily recommendation to lower blood pressure naturally.
  • Dr. Eric Berg notes average US intake is ~2,500 mg while Paleolithic diets provided an estimated 11,000–15,000 mg.
