Kidney Health - Foods That Are Good For You!

Kidneys play a vital role in maintaining the healthy balance between the body fluids by filtering out the harmful chemicals and toxins out of the body and the blood which gets flushed out with the urine. Thus, proper functioning of the kidney is vital to ensure a sound health. At times, some diseased conditions or unhealthy lifestyle habits (such as uncontrolled alcohol consumption, not drinking sufficient water, suppressing the urge to urinate regularly) can have deleterious and threatening effects on the kidneys. In addition to the above-mentioned triggers, the diet can also have an impact on the kidney health.

Some foods are known to work wonders to keep the kidneys healthy and disease free. In this article, we will discuss some of the foods that are indeed a blessing for kidney health and should be a part of our diet. Healthy foods for the kidneys Zeroing upon the right type of foods (both solids and fluids) can go a long way to keep the various kidney ailments at bay, ensuring that the kidneys function optimally. 

  1. Red bell peppers: Low in potassium and laden with Vitamins (A, B6, C, folic acid), Fiber and Lycopene (an antioxidant that comes with many health benefits), red bell peppers can do the kidney a world of good. 
  2. Garlic: Garlic comes with anti-inflammatory, anti-clotting, and antioxidant properties, all of which are essential to keep the kidney healthy.
