I like to snack on nuts as part of ensuring a high-fibre diet, but I prefer the taste of salted nuts over non-salted. Will eating salted nuts cause me significant dehydration or other health issues? Is it likely to cause me to have too high a daily salt intake? Or is it basically OK?
Like most foods, salt should be consumed in moderation. Your body needs salt, but a good idea would be to try and cut down salt from some other parts of your diet. For example, get unsalted fries or no ketchup. Check the daily recommended value for an estimate of how much salt you're intaking. Furthermore (thanks to Carey Gregory for pointing this out), drinking water may NOT be the best idea to offset the sodium intake. According to dietitian Monica Reinagel(from LiveStrong link),
"drinking some extra water after a high-sodium meal may help flush some of the sodium from your body and may also help get rid of some retained water to reduce bloating...
Just drinking more water, however, is not a solution for a long-term high-sodium diet, says Reinagel. The increased blood volume that results from your body holding onto the excess water is what raises your blood pressure.
So depending on the rest of your diet, you could better judge for yourself whether salted nuts are ok, or maybe unsalted would be better.
If you happen to have a high-sodium diet and don't like the taste of unsalted nuts, it would be a good time to look into alternative sources of fiber.

1Salt is highly hygroscopic so it seems likely that high sodium + high water intake will mainly result in a lot of water retention and the BP increase that will go with it. I don't think it's easy to flush salt out by drinking more.– Carey Gregory ♦Feb 7, 2016 at 18:49
@CareyGregory Thanks for bringing this to my attention. You are totally right. Furthermore, I didn't have any references here, which is VERY bad since we strongly encourage citing sources for information.– Dave LiuFeb 8, 2016 at 0:07
