Food provision in Australian aged care homes does not meet protein needs of residents: A call for reform

Abstract

AbstractAimMalnutrition is common in older adults in aged care homes, partly due to inadequate protein intake. Menu planning guidelines are available however, adherence to guidelines is unknown. This study aimed to determine; (i) what are the average serving sizes of menu items provided and do they meet recommended portion sizes? (ii) does consumption from a ‘typical’ menu provide sufficient protein? and (iii) can substituting a ‘typical’ menu with high‐protein options enable residents to achieve protein adequacy?MethodsThis study involved 572 residents (73% female; aged 86.4 ± 7.3 years) from 60 aged‐care homes in Australia involved in a 2‐year cluster‐randomised trial. During the trial, food intake was recorded quarterly using visual estimation of plate‐waste and 42 061 foods analysed. As part of a secondary analysis of these data, portion sizes of foods were compared to guidelines by calculating the mean (95% confidence interval). Items were deemed inadequate if the upper 95% confidence interval remained below recommended portion sizes.ResultsOn average 47% of breakfast and 80% of lunch/dinner items were below recommended portion sizes. Relative protein intakes, from a typical menu (most consumed foods), was 0.9 g and 0.8 g/kg body weight/day for females and males; both below recommendations. Substituting regular items with higher protein equivalents increased protein intake to 1.3 g and 1.2 g/kg body weight/day, for females and males, respectively.ConclusionAged care homes in Australia are not meeting menu planning guidelines resulting in insufficient protein being provided. Reform to menu guidelines including provision of high‐protein foods, will ensure protein adequacy in older adults in aged‐care homes.
