Managing chronic kidney disease (CKD) usually takes a two-pronged approach. There is what the physician does with the tests and the fancy pills, but then there is what you do at home. And what you do at home is perhaps equally if not more important than what the nephrologist does for you in the office. You need to watch your blood pressure and eat at a kidney-friendly diet

Let's take a moment to talk about the popular DASH diet eating plan that is probably the most recommended diet plan for people with high blood pressure.

But is it applicable if you also happen to have kidney disease? 

WHAT IS THE DASH DIET EATING PLAN?

Alarmed at the increasing incidence of high blood pressure (hypertension) in the US, the National Institutes of Health (NIH) conducted a multi-center study in 1992 to see how diet influences blood pressure, and what diet plan might be best for keeping blood pressure controlled. It compared typical American diets of the day to other diets including the so-called DASH diet. In a nutshell, the study found that ​people who ate the DASH diet showed a significant lowering of their blood pressure in as little as 2 weeks.

The DASH acronym stands for Dietary Approaches to Stop Hypertension. The approach emphasizes intake of fruits, vegetables, and low-fat dairy; while limiting intake of sodium, sugar, and red meat. It is low in saturated and trans fats and high in calcium, potassium, magnesium, fiber, and protein.

Here is how you should be getting your daily calories if you stick to the DASH plan:
