Those things didn't occur to me - because I've been doing them for years, but you're right. If you don't read labels and weigh food you're in the dark. MyFitnessPal is free (yes, ignore the ads) and is a great tool. I started using it to track my calcium, and have shifted the settings over time to watch protein, carbs, and sodium also.
Out of curiosity this evening I sprinkled a little regular table salt over my piece of sockeye salmon - and it was way too salty. Had to rub off some of it. With the wheat and most of the sugar out of my diet I notice my blood pressure is lower. I'll measure it this evening to see if it shows up via higher levels. I do get salt in and on other foods and it doesn't seem to make a difference.
