Generally speaking, added salt is something you need to avoid with young kids. Likewise for saturated fats.

I don’t buy the saturated fats thing either, except to the extent that they are a source of calories. If you have links to some studies that indicate negative outcomes vs the same caloric intake from other sources I am willing to read them.
