Low Protein Diet

468x60-DBF

A low-protein diet is any diet in which the protein intake is reduced. Anyone diagnosed with kidney or liver disease may be prescribed a low-protein diet. In any case, a diet which is especially low in protein should only be undertaken under medical direction.
Why is a low protein diet necessary?
Protein is needed, but can cause problems for diseased organs
Protein is necessary for a healthy body. When protein is metabolised by the liver and digested, urea is produced as a waste product. If the liver is diseased, then food metabolism is compromised. If the kidneys, which are responsible for excretion of urea, are not functioning properly (renal failure), or if high levels of protein are continually present in the diet, urea builds up in the bloodstream causing loss of appetite and fatigue. A low-protein diet will reduce the workload on these organs.
It is usually the case that serious liver and kidney disease are accompanied by the need to limit salt or sodium intake due to high blood pressure or fluid retention. Table salt (the primary source of sodium in the diet) should therefore be limited, along with other foods with a high sodium content, as an additional feature of the low-protein diet.
Too much protein can worsen your health
It is generally accepted that a healthy person needs 40-60 grams of protein each day to remain in good health. However, it has been reported that the amount of protein typically consumed by people in affluent societies (American diet typically comprises 12-15% protein) may overtax the kidneys – to the extent that up to 30% of kidney function may be lost by the time someone is in their eighties. High-protein diets for weight loss often recommend 30% or more protein in the daily diet, and in prolonged use can cause serious metabolic changes leading to bone loss and kidney stones!
Reduced protein intake can improve your health
Low protein diets (4-8% protein) are used routinely to treat patients with liver disease, kidney (renal) failure, and disorders involving the urea cycle, the metabolism, and amino acids.
How is a low-protein diet achieved?
Reduce amount of protein
Some of each type of protein should still be consumed each day from the two main sources:
Animal products (fish, poultry, eggs, meat, dairy products) – considered high quality or complete protein.
Vegetable salad dressings.
Use candy and sweeteners (hard candy, gum drops, jelly beans, marshmallows, honey, jam and jelly – even sugar (diabetics need medical advice).
Use canned fruits in heavy syrup.
