Research suggests that as people age, their ability to absorb or process protein may decline. To compensate for this loss, protein requirements may increase with age.
The study to investigated the relationship between protein intake and future decline in higher-level functional capacity in older community-dwelling adults in Japan.
The analysis included 1,007 individuals with an average age of 67.4 years who completed food questionnaires at the start of the study and seven years later. Participants were divided into four groups (quartiles) according to their intake levels of total, animal, and plant protein.
Tests of higher-level functional capacity included social and intellectual aspects as well as measures related to activities of daily living.
Men in the highest quartile of animal protein intake had a 39 percent decreased chance of experiencing higher-level functional decline than those in the lowest quartile. These associations were not seen in women. No decline was observed in plant protein intake for either sex.
