People with high amounts of protein in their urine, or proteinuria, may be in the early stages of, or at risk for, chronic kidney disease and should follow a diet that limits their protein intake, according to Davita. Those in the early stages of CKD can generally slow progression by reducing their daily intake of protein to 0.8 grams per kilogram of body weight.
The recommendation for individuals with high risk factors or symptoms of CKD is a diet that follows similar guidelines to the dietary approaches to stop hypertension, or DASH, eating plan, states Davita. Guidelines include reducing red meat to no more than 6 ounces per day and sodium intake to between 1,500 and 2,300 milligrams per day. People should limit alcohol intake as well as dairy foods that are high in saturated fat such as milk, cream cheese, yogurt, sour cream and frozen deserts.
Diet guidelines emphasize healthy food choices such as fresh vegetables and fruits that are high in fiber, as well as whole-grain products such as breads and high-fiber cereal, explains Davita. It's important to achieve a healthy weight by adjusting calorie intake based on a proper ratio of fresh produce and healthy fats. Foods that are baked or grilled are better than fried, and vegetables should be prepared without any sauces or cheese. Processed foods may have hidden amounts of phosphorus, and people should limit or avoid them on a healthy diet.
