When thinking about health, we often think about the heart, our skin, or weight. We rarely think of one of the most important and hardest-working organs of the body – the kidneys. Think of kidneys as our body’s filter system.
They remove wastes and excess water from the blood, keep mineral and fluid balance within the body, also regulate blood pressure, and even contribute to keeping the bones healthy. If the kidneys are not functioning well, this almost affects all the systems.
The wonderful thing is that working on your diet along with a good lifestyle can support kidney health without drugs. There is no single magic food, but including some kidney-friendly foods in your daily diet can retain kidney health for many years and meanwhile reduce the risk of developing kidney disease.
