Salt vs Sodium
In Spain, at least in some products, instead of the sodium quantity the salt quantity is displayed in the nutrition table. I have read that it could be made an automatic convertion (the salt contains 40% of sodium) from one to another and I think it would be interesting to include the option so that you could enter interchangeably one or other.
It also varies on Uk product.
It would be nice to have both field slat/soduim.
I personnaly ended up using the nutriment form to add salt
