High creatinine is often clinically indicative of abnormal kidney metabolic function in the body, and patients may suffer from kidney diseases, such as renal insufficiency. In addition to the need to follow medical advice for treatment, you should also adhere to the principle of eating less and more meals to improve the prognosis. Usually, patients with high creatinine specifically need to pay more attention to the following aspects, including low protein diet, low salt and low potassium diet, moderate fat intake, control water consumption, and provide sufficient vitamins, etc.: 1. Low protein diet: Patients should reduce the intake of plant protein and focus on high-quality animal protein, including chicken, fish, lean meat, etc. This is due to the fact that after consuming plant protein, the production of metabolites are more, may aggravate the burden of renal excretion, for the recovery of the patient’s condition is not positive; 2, low salt and low potassium diet: in order to reduce the high creatinine caused by the development of hypertension, hyperkalemia may, patients should pay attention to low salt and low potassium in the daily diet, reduce the intake of oranges, bananas, apples, strawberries, potatoes, as well as ham, pickles, salt, soy sauce, etc.; 3, intake of appropriate amounts of fat: egg yolk, Cream and other foods rich in saturated fatty acids may have an impact on the cholesterol content of the patient’s body, so it is recommended that patients reduce consumption, while dried fruits, olive oil and other common foods containing unsaturated fatty acids can be moderate intake; 4, control the consumption of water: patients with abnormal kidney function, there is already water and sodium retention in the body, and thus the need to control the intake of water, the specific amount of water depends on the patient’s urine volume the day before 5, provide sufficient vitamins: because patients need to pay attention in many aspects of diet, prone to malnutrition reaction, so should be scientific in the control of water, sugar intake under the premise of the intake of vegetables rich in vitamins such as cabbage, spinach, to ensure the normal operation of the body. In addition, since patients with high creatinine are likely to be complicated by hyperuricemia, they need to abstain from eating foods high in purines such as pork liver, pork lung, fish and shellfish. Foods high in phosphorus, such as sesame paste, carbonated drinks, black rice, purple rice and sorghum, may increase the risk of hyperphosphatemia and should also be reduced.
