To be specific, what I mean is once it’s in your body, your system breaks down salt the exact same way, no matter the source, so sea salt affects your body the same exact way as conventional table salt. And it’s not doing your body any favors in my humble opinion. It all depends on what you consider is “fine.” A little sea salt in your diet won’t kill you, but a lot might over a long period of time (years, decades, etc). That goes for anything that’s not paleo. We can survive on a steady diet of Twinkies into our old age, but when our health catches up to us, it won’t be pretty, I can guarantee that. I don’t want those results for my body, so I avoid it.
I also say, IF you use salt, please use sea salt, or another natural salt, unrefined and unadulterated in moderate amounts (I would not consider having it with every meal and drinking it in a glass of water every morning moderation). There are multiple articles on the internet about why table salt is worse for you (it’s usually been stripped of its minerals by chemicals), so just Google it if you want more info, but for my lifestyle, the food we eat already has all the salt we need to survive, and it’s already naturally balanced by the right amount of potassium, to help your body use the sodium in salt for good, not evil!
There are a lot of benefits to a LITTLE sea salt in your diet (especially if you sweat a lot), but I think there are even more benefits in not eating it. For me, the biggest reason is salt kills your taste buds, and the more you eat, the more you need to enjoy the taste of food. Once you’re off salt for a few weeks, the blandness in food goes away, and it’s replaced by an enjoyment of food you haven’t experienced since you were a child! Here’s an early post I wrote about salt for more info.
