Proteins intake

Sulfur. Sulfur is present in every cell in the body, primarily in proteins containing the amino acids methionine, cystine, and cysteine. Inorganic sulfates and sulfides occur in small amounts relative to total body sulfur, but the compounds that contain them are important to metaboHsm (45,46). Sulfur intake is thought to be adequate if protein intake is adequate and sulfur deficiency has not been reported. Common food sources rich in sulfur are Hsted in Table 6. 

The typical U.S. daily diet contains 1.1—3.6 mg of vitamin B, most coming from meats and vegetables. Poor diets may provide less than half of these amounts and less than the RDA. Some populations require higher amounts persons with high protein intakes, pregnant and lactating women, users of oral contraceptives, alcohoHcs, users of dmgs which interfere with vitamin B function, and those afflicted with some diseases. Several reviews have examined the relationship of vitamin B and specific diseases in more detail (4,23). 

The archaeologically most meaningful measure would be the proportion of animal protein in the total diet (weight consumed of total weight). What is a more straightforward indicator of meat intake based on 5 N measurements, is the proportion of animal protein of the total protein intake. When considering this, it is important to keep the following in mind ...

In addition to fiber and carbohydrate content, protein intake from legumes may have weight-loss benefits for obese individuals just because proteins enhance post-meal satiety (Rolls, 1995). However, a possible specific role for phytoestrogens in obesity has been postulated through the modulation of the satiety response, a neuroendocrine mechanism controlled by leptin (a hormone secreted by adipose tissue and already known to be regulated by...

Reduction in dietary protein intake has been shown to slow the progression of kidney disease.8 However, protein restriction must be balanced with the risk of malnutrition in patients with CKD. Patients with a GFR less than 25 mL/minute/ 1.73 m2 received the most benefit from protein restriction 8 therefore, patients with a GFR above this level should not restrict protein intake. The NKF recommends that patients who have a GFR less than 25 mL/minute/1.73 m2 who are not receiving dialysis, however, should restrict protein intake to 0.6 g/kg per day. If patients are not able to maintain adequate dietary energy intake, protein intake maybe increased up to 0.75 g/kg per day.15 Malnutrition is common in patients with ESRD for various reasons, including decreased appetite, hypercatabolism, and nutrient losses through dialysis. For this reason, patients receiving dialysis should maintain protein intake of 1.2 g/kg per day to 1.3 g/kg per day. 

The first-line treatment for the management of hyperphosphatemia is dietary phosphorus restriction to 800 to 1000 mg per day in patients with stage 3 CKD or higher who have phosphorus levels at the upper limit of the normal range or elevated iPTH levels.39 Foods high in phosphorus are also high in protein, which can make it difficult to restrict phosphorus intake while maintaining adequate protein intake to avoid... 

Nonpharmacologic Therapy Pruritus associated with CKD is difficult to alleviate. It is important to evaluate other potential dermatologic causes of pruritus to maximize the potential for relief. Adequate dialysis is generally the first line of treatment in patients with pruritus. However, this has not been shown to decrease the incidence of pruritus significantly. Maintaining proper nutritional intake, especially with regard to dietary phosphorus and protein intake, may lessen the degree or occurrence of pruritus. Patients who do not attain relief from other measures may benefit from ultraviolet B phototherapy.

Treatment involves the administration of large doses (as much as 1 mg) of intramuscular hydroxocobalamin. Administration of folate and betaine (see above) may be helpful, as is a reduction of protein intake. 

Approaches to reducing blood ammonia concentrations include In patients with acute HE, limit protein intake to 10 to 20 g/day while maintaining the total caloric intake. Protein intake can be titrated by increasing 10 to 20 g/day every 3 to 5 days to a total of 0.8 to 1 g/kg/day. With chronic HE, restrict protein intake to 40 g/day. 

Many diets exist to aid weight loss. Regardless of the program, energy consumption must be less than energy expenditure. A reasonable goal is loss of 0.5 to 1 kg per week with a diet balanced in fat, carbohydrate, and protein intake. 

Daily protein intake should be 1.2 g/kg for patients undergoing hemodialysis and 1.2 to 1.3 g/kg for those undergoing peritoneal dialysis. 

Vitamin Ba (pyridoxine, pyridoxal, pyridoxamine) like nicotinic acid is a pyridine derivative. Its phosphorylated form is the coenzyme in enzymes that decarboxylate amino acids, e.g., tyrosine, arginine, glycine, glutamic acid, and dihydroxyphenylalanine. Vitamin B participates as coenzyme in various transaminations. It also functions in the conversion of tryptophan to nicotinic acid and amide. It is generally concerned with protein metabolism, e.g., the vitamin B8 requirement is increased in rats during increased protein intake. Vitamin B6 is also involved in the formation of unsaturated fatty acids. 

Feeding human subjects meat-rich diets has been clearly and repeatedly associated with elevated urinary acid and calcium loss. Anand, et al. (12) fed college men low, medium, and high-protein diets. Fecal calcium changed less than 15%, whereas urinary calcium losses accounted for the major loss of calcium. Calcium loss and meat protein intake correlated directly. Johnson, et al. (34) reported that women showed a similar response when fed such diets. 

High intakes of protein, particularly animal protein coupled with low phosphorus intakes have been credited as resulting in high urinary losses of calcium and poor calcium balances which can be overcome by increasing intakes of either calcium or phosphorus or lowering protein intake in the adult human (9,15,16). In the present study, not only did the animal protein diet result in bones more resistant to breakage than did the plant protein diet, but the animal protein fed animals were seemingly less affected by variations in intake of phosphorus and calcium than were the plant protein fed animals. 

It has been well established that the ingestion of high dietary protein levels results in hypercalciuria in man, and that hypercalciuria is frequently accompanied by negative calcium balance (1-3). In a summary of data from nutritional surveys in the U.S., Pao (4J showed that dietary protein intake was well above the Recommended Dietary Allowances (RDA) for both men and women regardless of age (1). Although dietary calcium intakes are generally at the RDA for men, women below the age of 50 yr consume only 75% of the RDA (4J. Women above the age of 50 yr consume only two-thirds of the RDA for calcium (4). These low consumptions become critical when we consider the reduced ability for calcium absorption demonstrated in both men and women over the age of 60 yr (6).

On a world wide basis, man obtains approximately 70% of his daily protein intake from plant sources and 30% from animal and fish sources. These figures are 50 and 50%, respectively, for the developed nations, and 83 and 17% for the developing countries. Oilseeds and pulses (dry beans, lentils and peas) are concentrated sources of proteins, and are expected to play increasingly important roles in human nutrition as world population grows.
