Following the DASH eating plan and eating less sodium (salt) can lower high blood pressure or your risk for the condition. Following DASH also can improve blood lipid levels, which also helps reduce your cardiovascular risk.
Results from the DASH research showed that following a DASH plan containing 2,300 milligrams (mg) of sodium per day lowered blood pressure. Following a DASH plan containing 1,500 mg of sodium lowered blood pressure even more (systolic blood pressure was lowered by about 7 to 12 mmHg).
One important note: If you take medicine to control high blood pressure, you should keep taking it. However, you should tell your doctor that you're now following the DASH eating plan.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans.
