How much sodium is in our food?

Today for Hur6 for health we done this activity about how much sodium/salt is in our food that we eat in our everyday lives. So for the activity my teacher gave me a task to see which out of the 13 foods has the most sodium in it. I liked how I got some of the question's right but it was so frustrating trying to see which one has the most sodium. The highest food was ham but I don't why but I picked 2 minute noodles, because I thought that in the seasoning there would be a lot. The thing that I learnt during this was how much sodium is in it.
