Unless there is a medically diagnosed reason to limit salt, then there is no reason at all.
Research has shown that people regulate their own salt intake quite strictly, and that the amount of salt consumed per person around the world varies little.
There is no way that government can better regulate the amount of salt we eat than our own bodies do, quite naturally.
Here’s how that seems to work for me. I LOVE to eat sunflower seeds and much on them daily in the car. Salty? Yes, and they taste great. But if I’ve had too much salt or am dehydrated, they suddenly start to taste TOO salty, WAY too salty. It’s a signal to me that I need to dilute my internal concentration, and so I do.
