Cutting back on salt may not be as beneficial for your heart as once thought, a new study suggests. While a diet low in salt reduces blood pressure, it increases the levels of cholesterol, fat and hormones in the blood that are known to increase the risk of heart disease, the study found. Overall, the good and bad consequences of a low-salt diet may cancel each other out, so the diet has relatively little effect on the development of disease, said study researcher Dr. Niels Graudal, of Copenhagen University Hospital in Denmark.
