  • Water: More is NOT Better (article)
  • Are You Still Restricting Salt? (article)
  • Too little salt and excess water lead to a loss of potassium and magnesium via aldosterone (1)
  • Fructose increases alcohol clearance by about 100% (1)
  • Water “increases our metabolism” (increases energy expenditure) via stress, and this effect stops when the water is isotonic (same sodium concentration as in our blood) (1, 2, 3, 4, 5).
  • Eating too little salt increases stress, reduces the metabolism, and can lead to cardiovascular problems in the long-term (1, 2, 3)
  • Aldosterone (released in response to a lack of salt or excess water) directly causes cell swelling (1, 2)
  • Our sense of thirst comes before dehydration occurs (1, 2)
  • Our cravings for salt allow for adequate salt intake (1)
  • Coffee and other caffeinated drinks are hydrating and don't cause dehydration (1, 2, 3, 4, 5)
  • Salt intake under 2,300mg associated with increased cardiovascular disease mortality and all-cause mortality (1).
  • Increased salt intake up to 5,700mg sodium is associated with decreased cardiovascular disease mortality in a dose dependent matter and increased salt intake didn't increase the risk of hypertension (1)
  • A lack of potassium and magnesium causes hypertension (1, 2, 3)

    This was an awesome podcast! It was full of great, useful information! I’ve struggled with high blood pressure off and on during the last 10 years (I’m 66) and potassium always seems to help bring it down. Now, I’m going to really watch water intake and electrolytes.
    Thanks so much!!!
