Dietary protein forms an essential component of a healthy diet in humans. The Dietary Reference Intakes (DRIs) sets recommendations at a population level to ensure adequate intakes of protein from healthy food sources. The current recommendations for adults are set based on studies conducted using the nitrogen balance method in healthy adults; the limitations of which are well known. For other key life-stages such as childhood, pregnancy etc., a factorial approach is followed to set requirement values. Recently, with the use of state-of-the-art stable isotope based techniques the protein requirements have been re-examined in healthy adults, children, pregnant women, elderly and in childhood disease. The results suggest that the current recommendations may be significantly underestimated. Furthermore there is recent evidence that adequate protein intake during various life-cycle stages could affect long-term health outcomes. This talk will highlight protein requirements and how it might affect optimal growth and development.
