Rating (out of 5): 4

Protein intake is scientifically validated as an important component in the support and treatment of infections. During infection, the body’s metabolic rate increases, leading to greater protein catabolism and higher protein requirements. Protein is essential for the synthesis of immune cells, antibodies, acute phase reactants, and other proteins involved in the immune response. Numerous studies have demonstrated that protein-energy malnutrition impairs immune function, resulting in increased susceptibility to infections and poorer outcomes. Clinical guidelines, such as those from the Society of Critical Care Medicine (SCCM) and the American Society for Parenteral and Enteral Nutrition (ASPEN), recommend increased protein intake for hospitalized patients with infections, especially in critical illness or sepsis, to support immune function, wound healing, and recovery. Protein supplementation has been shown to reduce morbidity and mortality in malnourished patients with infections.

While the optimal amount and type of protein are still being studied, the consensus is that adequate dietary protein is crucial for maintaining immune competence and supporting recovery during infection. The evidence supporting the use of protein in infection is derived from both observational studies and randomized controlled trials in various patient populations, ranging from children with infectious diseases to critically ill adults. Therefore, the use of protein to support or treat infection is well-founded in current scientific literature.
