Creatinine, a type of molecular waste found in the blood, is created by muscle metabolism. It comes from the molecule creatine, which helps build muscle mass. Creatinine is filtered from the blood by the kidneys and expelled from the body in urine. However, people with kidney impairment sometimes cannot properly filter out creatinine. A high blood creatinine level is an indicator that a person may have a kidney problem. One way to help reduce creatinine levels and the strain on your kidneys is to modify your diet.
Drink at least six glasses of water per day. Drinking water will help flush excess creatinine out of your system.
Avoid salty foods. Foods high in salt can raise your blood pressure and cause prolonged damage to your kidneys.
Stay away from foods rich in protein, including meat and dairy products. Instead, eat more protein from sources such as beans and lentils. Cut down on foods rich in refined sugar.
Eat a diet rich in vegetables, fruit, whole grains and beans. You can get all the fats and sugars your body needs from these sources without putting a strain on your kidneys.
