Low Protein Diet

A low-protein diet regulates the dietary intake of protein to a prescribed level. It is intended to reduce ammonia or toxic nitrogen metabolites in people with malfunctioning liver and kidney.
- Protein allowances is computed at 0.5 to 0.8 grams per kilo body weight in the absence of edema or alternatively using the DBW. However, the diet must have at least 40 grams protein per day. Below this level, the diet is combined with keto acid or amino acid supplements.
- High biologic value protein sources are emphasized, at least 2/3 of the protein intake, such as those found in meats, fish, seafood, egg, and poultry.

When is it used?

- Acute renal failure
- Acute glomerulonephritis
- Chronic renal failure without dialysis
- Liver failure with impending coma

How adequate is the diet?

A low protein in all nutrients except for vitamin B12 and iron. Unless the diet is well planned, the low-protein diet may also be low in calcium, thiamin, riboflavin, and niacin. A nutrients supplement may be necessary to prevent deficiency.
