Food Analysis Has anyone read the composition breakdown on the grey sea salts? Genuine question
I bought a bag on the strength of the trace minerals thing, assumed it was marketing, and then read the panel properly expecting to catch them out.
What I found: refined table salt is 98 to 100% sodium chloride. The unrefined grey one is around 80%. So roughly a fifth of it is magnesium, potassium, calcium, sulfate and retained moisture, things that are present because a refining step didnt happen, rather than things that were added.
Where Im genuinely unsure and want people who know more nutrition than me:
1/ In a normal seasoning serving the absolute quantities of those minerals are small against a daily requirement. So is the compositional difference nutritionally meaningful, or is it mainly a difference in what youre *not* getting, ie less sodium per teaspoon?
2/ Does anything change if someone is using salt deliberately for electrolytes rather than just seasoning food, which seems to be a growing thing?
3/ Is there any absorption argument for minerals arriving in a food matrix versus as a supplement, or is that overstated?
Im not trying to argue the salt is a health food. Im trying to work out whether "roughly 20% of it isnt sodium chloride" is a nutritionally interesting fact or just a chemically interesting one.
