A new study has found that a low-sodium diet may actually increase the risk of dying from heart attack or stroke, but the findings have generated some controversy.

The study, published in the Journal of the American Medical Association, speculates that low sodium can decrease blood pressure, which might also decrease sensitivity to insulin.

Researchers say this could affect the nervous system and hormones regulating blood pressure and sodium absorption.

However, experts claim the study was flawed. They say it was too small and not representative of the general population.

Scientists also added that many more studies show evidence between high sodium intake and high blood pressure.
