In human physiology, nitrogen balance is the net difference between bodily nitrogen intake (ingestion) and loss (excretion). It can be represented as the following: Nitrogen is a fundamental chemical component of amino acids, the molecular building blocks of protein. As such, nitrogen balance may be used as an index of protein metabolism. [1]
The concept of "protein-sparing modified fast" (PSMF) was described by George Blackburn in the early 1970s as an intensive weight-loss diet designed to mitigate the harms associated with protein-calorie malnutrition [8] and nitrogen losses induced by either acute illness or hypocaloric diets in patients with obesity, in order to adapt the patient's metabolism sufficiently to use endogenous fat ...
The daily recommended intake for adults is 2 to 2.5 cups of each. Ideally this involves a mix of dark, green leafy vegetables, red and orange vegetables, and legumes, such as beans, peas, and ...
Biological value. Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism. Proteins are the major source of nitrogen in food.
The U.S. Department of Agriculture considers beans and legumes part of both the “vegetable” food group and “protein foods” group, along with meat and fish. Beans are classified as a fiber ...

Protein poisoning. Protein poisoning (also referred to colloquially as rabbit starvation, mal de caribou, or fat starvation) is an acute form of malnutrition caused by a diet deficient in fat and carbohydrates, where almost all bioavailable calories come from the protein in lean meat. [1][2] The concept is discussed in the context of ...
Digestible Indispensable Amino Acid Score (DIAAS) is a protein quality method proposed in March 2013 by the Food and Agriculture Organization to replace the current protein ranking standard, the Protein Digestibility Corrected Amino Acid Score (PDCAAS). The DIAAS accounts for amino acid digestibility at the end of the small intestine, providing ...
