One of the colon's main jobs is to absorb electrolytes. Since you no longer have a colon, it is recommended that you increase dietary sodium intake to help compensate. If you feel better with a higher salt intake, don't be afraid to eat a little more and monitor your BP to see if it really makes that big of a difference. Some people are more sodium sensitive than others, so not everyone sees sodium making a huge difference in BP.
I have had an ileo for 6 years, and eat a lot of salt. I feel best on a higher sodium intake. I also eat a very, very low carb diet. So having no colon and eating a low carb diet are 2 factors that make higher sodium consumption work better for me.
Sodium is demonized, unfortunately, along with saturated fat. Some very good info can be found in the book called The Salt Fix, if you are interested.
Don't be afraid to think differently about what we have always been told about diet for the last 50-60 years, and try different things to see what works best for you.
