Kidneys are a pair of organs present on either side of our spine, under the ribs and behind the abdomen in the shape of a bean. Their job is to filter the blood. They regulate the fluid balance of the body along with flushing out the toxins from it. Along with this, they also maintain the level of electrolytes in the body. All the blood in our body passes through the kidneys about 40 times a day. As such, it is very important for them to be healthy. One should know what foods should be added and subtracted from the diet for the kidneys to be in good health.
