Yes! Some meals are higher than others so it's important to read the label.
It's also important to consider sodium in the context of an entire day -- rather than one food item. That's easy to do with the alli Nutrition Log: it calculates everything for you!
In addition, some people are more sodium/salt sensitive than others. One of the natural functions of sodium is to bind water, that causes water retention (more in some people than others), and that will mask a true weight loss.
The recommended amount of sodium (because it IS an important nutrient) is 2,300 milligrams, or less, per day. If someone is having more than 3,000 mgs. per day that might cause more water retention. In that case it's a good idea to review your daily logs, see where most of the sodium is coming from, and then see what other substitutions you can make.
I hope this helps.
