Renal Failure: What Foods may Lead to Further High Urea Nitrogen

Blood Urea Nitrogen (BUN) is a significant indicator of kidney function but it is easily affected by many factors, such as food and diseases. BUN measures end products of protein metabolism in blood which are supposed to be excreted by the kidneys. However, patients with Renal Failure have different level of kidney damage so their BUN maybe higher than normal. There are some foods badly affecting BUN levels for Renal Failure patients. If patients with Renal Failure are going to check their BUN level or they want to reduce high urea nitrogen in their blood, they should reduce intake of the following kinds of foods.
1. Food with rich purine
Purine is found plenty in nitrogenous compounds. Purine will form uric acid after oxidation in the body. Excess uric acid accumulation in body will cause Hyperuricemia (also known as Gout). Patients with Renal Failure should avoid too much purine intake; here are some foods that rich in purine: animal livers, soybean and soybean products, peanuts, seafood and other bean products.
2. Excessive protein
As was remarked above, BUN is an indicator of end products of protein metabolism. Patients should just maintain adequate daily protein intake instead of excessive protein intake. Proteins are essential for remaining normal body functions but for patients with Renal Failure, much protein intake exerts an extra load of their kidneys resulting in acceleration of kidney damage. Patients with Renal Failure are recommended to consult a dietician who can give you specific advice based on your local food supply.
Except excessive purine and protein intake, patients with Renal Failure should eat less fat-contained food which may inhibit excretory of uric acid. Additionally, beer should limited within a small amount on account of inducing Hyperuricemia. There are some antihypertensive agents and diuretics also influence the elimination of uric acids.
Renal Failure patients should take some foods that are good for eliminating uric acids and declining high levels of blood urea nitrogen. You can consult our on line service or email to khkpcn@hotmail.com for better counseling.
