What does "allowance" mean? I don't think it has anything to do with the "allowance" that indicates the pocket money.

You're right! "Allowance" doesn't refer to pocket money here. Here, "allowance" means the amount something is permitted according to regulations or a specified purpose. You can think of it in relation to the word "allow," which means permission for something. So an "allowance" is the regulated and accepted amount of something that one is allowed to use or have. Here, they're talking about the expected and normal rate of consuming sodium and fat to maintain health. Ex: There's only a 25kg baggage allowance for our flight. Ex: I've already exceeded my sick-day allowance at school. Ex: My doctor said I have to make sure I don't exceed my daily sugar allowance.
