It was opinion. They don't know with concrete scietific evidence how much salt is good or bad for you. I'd suggest that too much of most things is bad for you therefore I choose to have everything in moderation and follow guidelines given out by the Food Standards Agency (http://www.eatwell.gov.uk/healthydiet/fss/salt/). Whether you follow that advice or not is up to the individual. Am I overweight? No, Is my blood pressure high? No. Is this due to controlling my salt and fat intake? I have no idea. But it works for me.
