People with mild high blood pressure who excreted more salt in their urine while following the DASH diet and eating within an 8-hour window also had bigger drops in their blood pressure.

People with mild high blood pressure who ate within an 8-hour window excreted more salt in their urine compared to those who only followed the DASH diet.

When people with mild high blood pressure followed the DASH diet and ate within an 8-hour window, those who lost more fluid around their cells also had bigger drops in their blood pressure.

For people with mild high blood pressure, eating all meals within an 8-hour window while following the DASH diet lowers blood pressure more than just the DASH diet alone over six weeks.

If you have high blood pressure and eat a lot of salt, switching to the DASH diet can lower your blood pressure by up to 10.6 points—but if you’re already eating very little salt, the diet might not help as much. So, it works best when you’re still eating salty foods.

Eating less salt and following the DASH diet together lowers blood pressure more than doing just one of them alone—and the biggest drop happens in people whose blood pressure is already really high (150 or above).
