A recent study published in The New England Journal of Medicine reports that salt reduction might have a greater effect on your blood pressure than you might think. The DASH diet is rich in fruits, vegetables and low-fat dairy. Within each group, subjects ate foods with high, intermediate and low levels of salt for 30 days. The researchers discovered that reducing sodium intake from the highest to the intermediate level reduced average systolic blood pressure in the control group and the DASH group. The greatest reduction occurred in subjects who consumed the low-salt DASH diet.
Chances are, the answer is yes.
