These are very interesting articles - I did a blog post a while back on salt and read up on the pros and cons and the industry reaction. The sad thing is that the wing-nut zero-sum approach will probably do more to fuel the industry's assertion that they can't make good food without high salt levels, even though that's what most of us do in our own kitchens.
In general, the response to any health issue lately has been that both sides play around with the truth until it suits them, which is a shame, because it often means that things don't improve when they could. I thought the Institute of Medicine's approach was a good one - they assert that most people won't notice a gradual reduction in sodium over time, and suggest that if this was done systematically, it might address the issues the food industry fears. It's important to keep in mind that only about 11% of our sodium intake is added by the consumer - so palatable food
can and
is being made with less salt; heavy processing is what's driving the extra sodium.
It could certainly be said that most people don't suffer from hypertension and don't need to watch their salt intake - but in general, the people who are at risk are vulnerable physically and financially - and are most likely to be eating a steady diet of highly processed foods. If a gradual reduction (the key being gradual) in sodium won't hurt the rest of us, I think it's a good thing.
