The risk of kidney damage increases with aging. Starting at the age of 40, the glomerular filtration rate, which is a parameter of the function of all organs, decreases by 1% per year. That is why we must take care of our kidneys to stay healthy until we are old.

The kidneys are bean-shaped organs, the size not bigger than your hands. These organs are sophisticated units for the processing of a wide variety of substances and are tasked with keeping the blood clean and chemically balanced. The kidneys process blood and separate harmful substances and water. These two are an integral part of the urine that is retained in the bladder before being eliminated from the body.

Harmful substances in the blood are produced during the procession of various tissues, and they originate from the food we eat. The body takes in nutrients from the food, but these harmful substances are transported to the blood. Kidney function is very important as they remove these substances from the system. If the kidneys do not function properly, toxic substances build up in the blood and can harm your body.
