The requirement for dietary protein is often a controversial topic and perhaps more so for older persons in the throes of sarcopenia. The, in my view, inaptly named “Recommended Dietary Allowance" or RDA for protein – 0.8 g protein/kg/d – is poorly understood. Many consider the RDA to be a target for protein intake rather than the amount of dietary protein that should be ingested to balance the losses of nitrogen, with a margin or error, for ~98% of the population. You will note that there are no tangible health or other related outcomes associated with the RDA for protein, only that it is the protein (nitrogen) intake to cover losses. People often ask, “Do people need to consume more protein than the RDA?" I believe the most prudent answer is yes. Nevertheless, the more important question is, “Could people benefit from consuming more protein than the RDA?" The answer is a qualified yes, but an unqualified yes for older persons. In this seminar, the latest research on protein requirements for older adults will be examined and what those requirements mean to mitigate sarcopenia.
Learning Objectives:
At the end of the webinar, participants will be able to:
- Explain the limitations of the protein RDA and especially for older persons.
- Articulate the potential benefits of consuming protein at levels greater than the RDA for older persons.
- From common criticisms, defend higher (than the RDA) protein diets for older persons.
