Why a low salt diet can cause more problems that a high salt diet. Never as straightforward as we would like eh folks ?
"A study of more than 100,000 people found that both low and high sodium excretion, which is directly related to sodium consumption, was associated with an increased risk of death and cardiovascular disease.
Why? There’s surprisingly little rationale for this belief. Last year, experts convened by the Institute of Medicine assessed the evidence concerning sodium intake around the world. They agreed that efforts to reduce excessive sodium were warranted. But they cautioned that no such evidence existed to recommend a very low salt diet. They hoped that future research would assess the potential benefits of a diet where sodium intake was 1.5 to 2.3 grams per day.
The second New England Journal of Medicine study did just that. In addition to looking at high sodium diets, it also compared the health outcomes of those who had very low sodium diets. What they found was worrisome. When compared with those who consumed 3-6 grams per day, people who consumed less than 3 grams of sodium per day had an even higher risk of death or cardiovascular incidents than those who consumed more than 7 grams per day.
This result would be shocking if we in the medical community hadn’t seen it before. But we have. In 2011, researchers published a study in the Journal of the American Medical Asssociation after following 3,681 people over almost a decade. They, too, found that excessive salt intake was associated with high blood pressure. They also found that a low-sodium diet was associated with higher mortality from cardiovascular causes."
