Reading Fuhrman’s Eat For Life. Has a very interesting section on salt. Views salt from the evolutionary perspective of what humans in the bulk of their existence have taken in, that is, just the salt in the food and nothing more. That’s the amount our bodies through all those perhaps millions of years the human body is accustomed to need.
But then he compares that to the modern diet where everyone adds salt to virtually everything, so our current salt intake is spectacularly above where it should be. So we eat way too much salt compared to what we should be consuming, but worse, that amount of salt changes one’s taste buds to having to expect virtually everything one eats to be salty. So the current modern salted diet has radically changed the modern taste buds.
Only by drastically reducing salt can someone eventually get back to taste buds as they were meant to be, where one can pick out the more subtle flavors of various foods.
So the current heavily salted diet leads to high blood pressure and poor health, but also undermines one’s sense of taste. Goes on to say that his Nutritarian diet will lead to this reawakening of one’s true taste buds, and so you will get much more enjoyment out of actually tasting a variety of unsalted foods.
