I no longer post here but think your misrepresentation of the facts might be dangerous to the casual reader. The Framingham study did NOT say that low sodium intake is more associated with high blood pressure than high intake. It said there was a J-relationship between sodium and cardiovascular risk, including BP. Diets very high in sodium still carry a high risk and so do diets that are very low. Most people fall in the well of the J, which is fortunate for them. Guess we can ignore you on the climate thing too.
