Salt Deficiency: the cause of many serious diseases http://www.shirleys-wellness-cafe.com/salt.htm#1
There was a time when I didn’t even have salt in the kitchen. Yes, I admit it. I can be (or hopefully used to be) just as susceptible to media hype that latches on to easily marketable over-simplifications that sell more newspapers or whatever, as the next person. Fact is the electrolytes found in salt, especially sea salt are absolutely essential to life.
“An eight-year study of a New York City hypertensive population stratified for sodium intake levels found those on low-salt diets had more than four times as many heart attacks as those on normal sodium diets.”
That’s a pretty shocking statistic, isn’t it! Especially since it’s the people who are trying to be healthy are the ones who actually do things like to cut back on salt. Runners who shun salt, and who also drink distilled water (with all the electrolytes removed), are at even at greater risk since water is the pre-condition for the body absorbing rather than losing electrolytes.
That’s one thing, the other is that the body becomes acidic from the lactic acid, overheating and the usual shut down of deep organs, etc. produced by physical exertion. Because all cells like to fire at maximum capacity, the body will attempt to regain acid base equilibrium ie. balance body pH chemistry by pulling electrolytes from anywhere it can get them… bones for example. Exercise usually is not able to restore the normal alkaline balance, as is obviated by the hyperventilation which ensues after a few moments.
Add to that the risk of fibrillation (disruption of the electrical activity of the heart) during running (acidosis during endurance cardio workouts can imbalance the electrical action potential of positive and negative ions inside and outside the heart cells) and it could explain why the risk of heart stroke or cardiac arrest is so high amongst those inclined to follow a health fad like reducing salt intake.
I’ve also found a daily cardio warm-up routine that prevents the body becoming acidic during exercise improving cardiovascular health.
