Before you chuck your salt shaker for fear of sodium's health consequences, you should consider a new study from Ontario, Canada's McMaster University. Researchers found that contrary to the long-held public perception of salt's negative effects, a low-salt diet may not be beneficial for your health after all—and might even have its own grave consequences. While other recent studies have suggested salt isn't as bad for you as previously thought, this study suggests that a low-salt diet could actually increase the risk of health issues such as heart disease.
The large-scale study by the university's Population Health Research Institute involved more than 130,000 people from 49 countries, and looked at the relationship between sodium intake and stroke, heart disease and death. The researchers particularly focused on the differences between people with high blood pressure compared to those with normal blood pressure when it came to the effects of salt on the body.

The results showed that regardless of a person's blood pressure level, a low sodium intake was in fact linked with more heart attacks, strokes, and deaths compared to an average intake, Science Daily reports.
