Not much. If a food is vastly high in cholesterol, those with high cholesterol will know to avoid it. However most foods do not need a cholesterol label for people to know that it's high in cholesterol - you can just look at the ingredients if necessary and judge by the amount and order of high cholesterol products listed.
Ingredients are listed by amount. If the first ingredient listed on a bottle of hand lotion is water, the main ingredient is water. Likewise in food. If the first two ingredients of a preprepared sauce are water and salt, there is more water and salt than anything else in that sauce.

An easy way to reduce salt would be to only use Kosher, Most spices now-a-days are part salt, or if you read the label, mostly salt. Garlic salt can easily be substituted with some kosher salt, and some garlic powder. This however is just for spices, food wise, buy fresher ingredients. Most "quick" foods today contain a lot of salt, mostly to preserve them, so when you intake said food, you may not be able to taste the salt but it's there. Your best bet is to read labels before you buy ingredients or just use plain spices such an Ground Black Pepper, or plain Kosher Salt. And NEVER use pre-made rubs. Most rubs today are almost all salt.
