Doctors and health experts have been telling us for years to cut the salt in our diets.
However, a new study says sodium may not be that bad for your health.
Researchers also say cutting your salt intake too much could increase your risk of heart attack or stroke.
There's no firm explanation for the findings, but researchers say low sodium can decrease blood pressure, which might also decrease sensitivity to insulin and encourage stress.
The findings appear in today's issue of the Journal of the American Medical Association.
