I've been on a no salt diet since 1968. My mother oversalted everything. When I started cooking for myself I didn't put salt in anything unless it was required for a chemical reaction. I put salt in the water when I boil eggs in case of one cracking. It causes the white to coagulate and seal the shell.

The difference you might be feeling is a lowering of blood pressure.

It varies from person to person. In my case a severely upset digestive system. It got so bad that I developed an extremely itchy rash on my arms.

You can test for it by avoiding gluten for 2 weeks, then having a small amount for several days and comparing how you feel. Be aware that many things have gluten in them. Read labels carefully.

I mostly eat fruit, vegetables and meat and generally avoid the aisles in grocery stores, shopping just the perimeter.

From my experience, I react with aches and fatigue, or even swelling on my face, hands, and feet (flare up) the next few minutes or the next day(s) when I eat anything with monosodium glutamate or MSG, gluten, tomatoes, eggplant, artificial sugar, and even white rice.

What does Gluten intolerance feel like.

Many of us are gluten intolerant. Fish isn't popular in our house either.
