Is Sodium good for you?

Kamusta! In Health today we learnt about Sodium, aka, salt. It's in almost everything. We need it to live a healthy life but at the same time eating too much of it can be unhealthy. Today, we had to rate 13 packaged foods depending on how much salt we think they have in them. Something interesting I learnt today was that 2 Minute Noodles actually don't have a lot of sodium included.

How, much sodium do you think a teenager should consume daily?
