Sodium intake (i.e., even a pizza) will raise my BP. I take no salt, drink no electrolytes. We don't even have salt in the house. However, you can't get away from it with processed foods or restaurant foods. Somehow, I do my 40 mile rides in the summer just on a bit of plain old water. When I was doing longer rides, I used some gatorade, never anything fancier. Those were the ancient days, before all the new-fangled stuff.
