Creatinine is a by-product of the filtration of the blood. This is a nitrous acid is produced by the kidneys and is stored in muscle cells. The liver and the pancreas aid the kidneys in the synthesis of creatinine. At any point in time, our body has a healthy level of 120 grams of creatinine, of which, we expend about 2 gm every day. The extra creatinine is filtered by the kidneys and expelled from the body through the urine.If a there is more creatinine that the normal range in a body, it is because the kidneys are malfunctioning and are unable to filter the creatinine out. Kidneys stones can often cause the creatinine levels to rise. These kidney stones in the kidneys are extremely painful. They may even eventually cause injuries. If the kidney stones move around in the kidneys, they can cause rupturing of the kidney’s membranes and you may see blood in the urine. Kidneys and stones do not go well together. Kidneys are a very important organ in the body, and it is important to ensure that you keep them healthy.
High Protein Foods
Your body uses protein to build and repair tissues and muscles and to fight off infection. When protein is broken down, like any other food, it produces certain waste products. One of these is urea, which damaged kidneys have trouble filtering out of the bloodstream. Most renal diets require you to monitor and limit your protein intake. Your doctor, dietitian or nutritionist will tell you how much and what types of protein you can consume. You will probably be allowed certain amounts of complete proteins from animal sources (lean beef and chicken, for example) and certain amounts of incomplete proteins from plant sources (beans and lentils).
High Sodium Foods
When kidney disease or high blood pressure is suspected, the first dietary change is often to reduce sodium in the diet. Fresh foods over packaged, convenience foods are recommended. Canned foods are particularly high sources of sodium in the American diet. When eating out, those trying to lower their sodium intake should avoid fast food restaurants and ask that foods be prepared without salt.
High Phosphorus Foods
Your body uses phosphorus and calcium to keep your bones strong and to keep your muscles and nerves working normally. Calcium and phosphorus must remain in balance. When you have kidney damage, your body has trouble maintaining this balance. You often end up with too little calcium and too much phosphorus. Your body then steals calcium from your bones to try to restore the proper balance, and your bones become weak and brittle. You may also experience pain in your bones and joints and itchy skin. Foods that are high in phosphorus include sardines, cola, nuts, cheese, liver, peanut butter and beer. You may also be asked to avoid eggs and dairy products.
High Glycemic Foods
Because uncontrolled diabetes can lead to kidney damage, foods to avoid are those that have a greater impact on blood sugar. DiabetesNet offers a list of foods that are most likely to raise blood sugar, called high glycemic index foods. White, refined flour should be replaced with whole grains, such as whole wheat, oats and barley. Sugary foods such as cakes, cookies, pies and candy should be limited or eliminated.
