UK guidelines recommend not exceeding 6g of salt per day (or 2400mg of sodium). Most UK foods list the salt, but MFP asks for the sodium values and tracks Sodium.
For those interested in tracking their salt, or those who enter items on the food database (for which I thank you), I have included the salt to sodium conversion formula below;-
Salt to sodium
To convert grams of salt to milligrams of sodium, divide the salt figure in grams by 2.5 and then multiply by 1,000 to get milligrams. So
grams of salt ÷ 2.5 = grams of sodium X 1,000
6 grams of salt
6g ÷ 2.5 = 2.4g salt ... then multiplied by 1,000 = 2400 mg of sodium
So 6 g of salt equates to 2400 milligrams of sodium
