"Recommended daily protein intake too low for the elderly

The minimum protein requirement for healthy adults has been set almost 15 years ago but there is a growing body of evidence that this recommended dietary allowance (RDA) is not sufficient for older persons.

The RDA you will find on the nutrition labels on your food, however, were set in 1968, and the ones used by researchers and professionals were set in 2003. A recent review published in Frontiers in Nutrition points out that both these values do not do justice to the protein needs of the elderly and critically ill.

"A big disservice is being done. The prescribed 0.8 g/kg/day just isn't enough protein for the elderly and people with a clinical condition. This shouldn't be communicated as what is 'allowed' or even 'recommended' to eat.," author Stuart Phillips of McMaster University in Canada explains.

In his review, he points out that the quality of proteins should be considered when setting the RDA guidelines and recommending protein supplements. He argues that there should be a stronger focus on leucine; an indispensable amino acid and building block for proteins.

The elderly have a higher need for leucine to build muscle proteins, and milk-based proteins (e.g. milk and whey) are a good source for this.

Moreover, it may be highly beneficial for the critically ill patients that rapidly lose lean body mass (i.e. the body weight minus body fat) to increase their protein intake. Again, elderly ill patients would benefit the most from this. "I think it's clear we need some longer-term clinical trials with older people on higher protein intakes. These trials need to consist of around 400 -- 500 people.," Phillips argues.

He is not the first researcher to challenge the current protein RDA, and hopes his message does not fall on deaf ears. That is also why he chose to publish Open Access: "I love to publish work that everyone can read. The days of publishing a paper that only people in academic institutions can read are over. I think it is essential that everyone and not only your scientific colleagues can read the work we do."
