Yes, foods heavy with sodium can do it, and remember, just because it doesn't taste salty to you, it can still have extra sodium in it.
It can also be due to more intensive exercise (running instead of jogging or walking, lifting heavier weights, etc.). You can tell if you're sore the next day or next couple of days.
I'm sure there can be other causes, too, so if salt or your workouts aren't the cause, you may want to see your doctor.
Other than that, if you really need to step on the scale every day, don't let the weights in-between get to you. Watch how you do over the course of the full week and full month. As long as you're trending downwards, you're good!
