I think it all comes down to how many you have. They are a reasonable treat for the calories but you are right about the salt they have a high sodium content so that is something to take into consideration.
If a handful is about 10 then that is probably OK for a snack. Nutritionally they are very high in sodium, high in carbs, some protein, low fat and very little sugar. For those who are interested they seem to come in at around 150-190 cals for about 10 of them.
Hope this helps.
