I came across an interesting article/web site that promotes treating advanced Lyme disease with a daily regiment of nothing more than salt and vitamin C.
Proponents of this approach point out that salt is a natural anti-microbial and it was not long ago that humans consumed a lot of salt because salt was one of the primary forms of pre-refridgeration preservation. They hypothesize that the lack of salt in the modern diet is one of the causes of outbreaks of various diseases and conditions. This level of salt intake is probably not paleo; but it might be a good thing in an industrialized society where we are constantly exposed to germs and toxins that our paleo ancestors never knew.
The line of reasoning is very similar to that of saturated fats -- the gummint has been warning us to eliminate them because they're dangerous, when in fact they are not only NOT dangerous, but good for us, in fact essential.
I am not at all a conspiracy theorist, but I think the government and its bodies are giving advice which is exactly opposed to promoting good health.
