You need salt. Salt is one of two elements that regulates water in your cells. The elderly,scared of salt , suffer widely from hyponutrmia and dehydration. Without salt, water doesn’t transfer into your cells. You can drink water all day but without salt it will only puss out.
The other mineral electrolyte you need to balance the water in your cells is potassium. Potassium allows the water to leave your cells.
Without potassium you will also be dehydrated. Too much salt over potassium and you get high blood pressure. Too much potassium over salt and you can get heart palpitations or arrythmias.
With the two in balance, you have no adverse symptoms and remain hydrated.
I can promise you that you aren’t getting enough potassium. To reach the daily recommended amount of potassium, you’d have to eat 6 large sweet potatoes a day. You can not eat that much potassium in this society. to get what you need. We don’t eat like that anymore because we are not plowing the back 40 after lunch, or cutting wood to last a winter after we build our own house. And barn. And clear our own land and plant it
You could eat as much salt as you wanted as long as you had the potassium to balance it.
Up your potassium and get the daily recommend amount. And stop worrying about your salt. The two work together.
