Creatinine -rich diet: what to eat and what to limit

If the tests show that you have high creatinine levels in your blood, you may need to change your diet, according to the National Kidney Foundation. It is a good idea to work with a registered dietitian-nutritionist who specializes in the management of kidney disease. They can teach you what the best foods for you according to your specific condition. They can also teach you about eating intelligent portions and quantities of these foods.

As a rule, eat large amounts of animal protein – found in red meat, fish, crustaceans such as shrimp, chicken and other poultry, eggs, cheese and yogurt – can affect the accumulation of creatinine. If you have a high creatinine, it is preferable to search for expert food advice on the quantity of protein that you must obtain every day to maintain muscle mass and other key corporal functions without damage to your kidneys, depending on the centers for DISSE Control and Prevention (CDC).

Conversely, plant proteins seem to have kidney protection effects, according to a study. It is a good idea to work with a dietitian to find out how priority of protein sources (such as beans and legumes) to meet your daily needs can also support your kidney health.

While people with high creatinine levels should avoid eating too much animal protein, they should try to eat fiber -rich foods more regularly and in many cases in higher quantities. In addition to supporting digestive and intestinal health and reducing blood creatinine rates, a diet rich in fibers can also have a preventive effect on associated risk factors of kidney disease, according to research.

According to Mayo Clinic, good sources of fiber in a balanced diet include:

Fruits and vegetables

Foods with whole grain such as whole wheat bread

Legumes

Nuts and seeds

If your high creatinine levels are an indication that you have a chronic kidney disease, you will want to be aware of the fluids and several nutrients you take.

According to the National Kidney Foundation, here are some key elements to know:

Liquid When the poor kidney function decreases the amount of urine you pass, drinking too much liquid can cause swelling, high blood pressure and excess stress on your heart.

sodium Similar to liquid, when your kidneys do not regulate your sodium levels well, too can cause swelling, high blood pressure and stress on your heart.

protein Get more protein you need, especially from animal sources, can create an accumulation of additional creatinine in your blood.

phosphorus Too much from this mineral can weaken your bones and the damaged kidneys do not filter it as they should.

potassium This nutrient is important for muscular and nervous function, but poor kidney function can cause potassium accumulation in your blood – and this can cause dangerous heart problems, according to the CDC.
