Protein nutrition optimization

Protein nutrition optimization involves mathematical and dietary strategies to achieve high-quality protein intake, often using metrics like PDCAAS or DIAAS to balance amino acid profiles, digestibility, and essential nutrients such as iron, zinc, and fiber in meals. It emphasizes ratios of plant and animal proteins to meet daily needs of 1.2–1.6 g/kg body weight, particularly for older adults, athletes, or those in catabolic states to support muscle protein synthesis and prevent sarcopenia. Biological roles include tissue repair, enzyme function, hormone signaling (e.g., insulin, glucagon), fluid balance via albumin, and immune support, with proteins comprising major body components like muscle and collagen. In disease, suboptimal optimization contributes to muscle wasting, malnutrition, and impaired recovery in critical illness or aging, while higher intakes preserve lean mass. No drugs directly target this concept, as it focuses on whole-food approaches rather than molecular intervention, though challenges include ensuring bioavailability from plant sources and avoiding excess oxidation of amino acids.
