Instead of regulation of additives (salt & sugar) follow doctor's advise
We are all different, no matter how organizations keep saying all people are the same. Regualar blood tests can tell if you need to reduce salt and/or sugar. Or your level might be just right.
Just like cholesterol, an over weight person with little exercise and ok diet can have good cholesterol and a will fit person, lots of exercise, good diet can have heavy cholesterol.
I have seen both cases and believe it is common. I believe preventive doctor care is more important to determine one's health than someone you have never met.
