Creatinine is a byproduct of regular muscle protein metabolism. Under normal circumstances, creatinine is filtered by the kidneys and expelled from the body during urination.

However, impaired kidney function or chronic kidney disease can cause creatinine to accumulate in the body and become apparent in blood and urine in higher than normal levels.

According to the National Kidney Foundation(1), 1 in 3 American adults is at risk for kidney disease. There are, however, ways to lower creatinine and improve kidney health. Check out this article to find out how to lower creatinine.

CURE 1: Diet

If your creatinine levels are higher than normal, it is critical to incorporate diet strategies and good nutrition as a part of your treatment plan. Here’s how you can lower your creatinine levels naturally by modifying your diet:

Foods to Include

1. High-fiber Foods

Studies show that consuming foods with added fiber may help to reduce serum creatinine levels. It is important, therefore, to try and increase your fiber intake. You should include at least one serving of about 25-30 grams of fibrous food in your daily diet.

Foods to Avoid

1. High Protein Foods

Foods that are high in protein can increase the stress on your kidneys as they are hard to metabolize. It is, therefore, advisable to eliminate high protein foods such as red meat and dairy from your diet. This does not, however, mean that you need to cut out protein completely. Plant-based sources such as nuts and legumes(2) are nutritional powerhouses and can be consumed in moderate amounts to keep your energy levels stable and maintain other bodily functions.

2. Salt

Too much sodium can wreck the health of your kidneys as it reduces its ability to remove water, and can lead to high blood pressure. Your average daily sodium intake should not, therefore, exceed 2 to 3 grams.

2. Get adequate sleep

Healthy Sleep

3. Avoid over-exercising

While regular exercise is definitely important, rigorous physical activity when you have chronic kidney disease will only elevate your creatinine levels further. Since creatinine is a byproduct of muscle metabolism, strenuous activity will result in increased muscle breakdown and thereby, higher creatinine levels. Try yoga or walking to stay active and healthy instead.
