Each year, the DASH diet earns high marks across several categories in U.S. News & World Report’s Best Diets rankings. DASH is designed to help control high blood pressure, but when followed closely it may offer additional benefits, such as:

  • Weight management
  • Higher levels of HDL (aka “good” cholesterol)
  • Lower levels of LDL (“bad” cholesterol)
  • Improved blood sugar control over time (A1C level)
  • Reduced risk of kidney stones

Madhu Challapalli, MD, a cardiologist and internist in New Braunfels, Texas, explains how the DASH diet works and offers simple tips to help you stick with it.
