Creatinine is a waste product in the body that is produced when we build and use our muscles. Healthy kidneys filter this waste out of the body through urine, along with other toxins and fluids. When kidneys begin to lose their functionality, however, they are unable to effectively remove creatinine from the body. This can lead to kidney damage and other complications, such as chronic kidney disease (CKD) or end stage renal disease (ESRD).
There are a few easy adjustments you can make in your daily routine to help lower your creatinine levels. If you or your doctor are concerned that you may be developing CKD or other kidney-related conditions, consider these five diet tips to help keep your creatinine levels in check:
Cut back on protein
Foods rich in protein, such as red meat, chicken, fish, eggs, cheese, milk and yogurt can cause creatinine levels to rise. Unused protein in the body is broken down into creatinine, which builds up in the blood stream. Cooked red meat is particularly known for increasing creatinine levels. The heat used to cook the meat causes the creatine in the meat to produce more creatinine. If you can, cut back on your protein intake and replace these foods with more plant-based options.
Increase your fiber intake
Research suggests that foods with more fiber can lower creatinine levels in patients with CKD and improve their estimated glomerular filtration rate (eGFR). Select whole grain options when you can and incorporate nuts, seeds and barley into your daily menu. These often make great substitutes for flour- and rice-based recipes, so you shouldn’t have to give up any of your favorite meals or snacks.
Eat the right kinds of fruits and vegetables
Another great source of fiber and other nutrients are fruits and vegetables. However, it’s important to choose the right kinds to protect your kidneys – particularly, those with less potassium and phosphorus. Instead of a banana or an orange, reach for an apple or a handful of berries. Instead of asparagus, use broccoli or cabbage. Fruits and vegetables are an important part of any balanced diet, especially when you are watching your creatinine levels.
Avoid excess salt
If you have or are at risk for high blood pressure, it’s important to stick to a low-sodium diet. It’s recommended that those with kidney complications should consume less than 2,000 mg of salt per day.
Use the right supplements
While there is no definitive scientific research, it has been observed that chitosan, salvia or nettle leaf supplements have helped improve renal function and decrease creatinine levels in patients with CKD. Since herbal teas and supplements may interfere with certain medications, consult your doctor before incorporating them into your dietary routine.
Stay hydrated
In general, it’s recommended that you drink six to eight 8-oz glasses of water every day. Dehydration can cause creatinine to increase, due to the lack of fluid in your body. This means you produce less urine, and since creatinine is flushed out through urine, this could lead to a build-up in the blood stream. However, consuming too much fluid can cause an increase in blood pressure, putting additional stress on the kidneys. Unless advised differently, you should drink the recommended amount of water daily. You can also determine if you have normal urine creatinine levels with a creatinine level test, administered by your doctor.
Creatinine is a major factor in CKD, ESRD and other kidney-related conditions. Making a few minor lifestyle adjustments can help ensure you are doing everything you can to protect your kidneys and keep your creatinine at a healthy level.
