Salt – it makes your food so much more flavorful, but we also know that it's not necessarily good for us. In small pinches, salt is important for the body, because it is an electrolyte that helps balance fluids in the body. The problem is that salt also has a major impact on our heart and kidneys. Too much sodium makes it harder for the kidneys to eliminate the excess sodium, which may lead to an increase in blood volume. This can contribute to raising blood pressure to a dangerous degree.
