Salt levels for children and adults

The Scientific Advisory Committee on Nutrition recommended salt intakes for children and adults

So you can see that the limits for young children are very low. If you think that a slice of bread can contain 0.5g of salt or more and a bag of crisps has 0.5g, it’s easy to see how some toddlers could be exceeding their salt limit regularly. Manufactured baby foods for up to 7 months cannot contain added salt by law, as babies’ kidneys cannot process salt properly and it is dangerous for them to eat salt.

Parents do need to be careful not to add any salt (or products like ketchup, stock cubes, soy sauce mayonnaise, etc etc) when they are making their own baby foods. It may taste bland to them, but babies who have never tasted salt will certainly not miss it!
