    Tackling malnutrition with a new compact oral nutrient supplement among residents in aged care: a pilot study
    (CSIRO Publishing, 2022) O'Brien WJ; Jellicoe J; Mazahery H; Wham C
    Introduction: There is a high prevalence of malnutrition among older adults entering residential aged care (RAC). Aim: To determine whether 60 mL of a compact oral nutrition supplement (ONS; daily total: 576 kcal, 35 g protein) consumed four times daily with medication rounds improves malnutrition status, body weight, and body composition measures among older adults in RAC. Methods: Residents (n = 20; mean age: 86.7 ± 6.8 years; 50% female) screened for malnutrition (20% malnourished, 80% at risk of malnutrition) using the Mini Nutritional Assessment-short form were recruited during April–June 2021. Participants received 60 mL of an ONS four times daily using the Medication Pass Nutrition Supplement Programme (Med Pass). The ONS intake and participant compliance were recorded. Body mass index, fat, and muscle mass (bioelectrical impedance), malnutrition risk, depressive symptoms, and quality of life were assessed at baseline and following the 18-week intervention. Results: Median overall compliance was 98.6%. An ONS intake did not significantly increase mean ± s.d. any body composition measures or improve health and wellbeing outcomes; however, it resulted in increased body weight and body mass index (BMI; 13/20 (65%) participants), body fat mass and percentage (10/16 (63%) participants) and muscle mass (9/16 (56%) participants). Malnutrition risk scores improved in 65% (13/20) of participants, resulting in 10% being assessed as malnourished, 65% at risk of malnutrition, and 25% with normal nutrition status. Discussion: Delivery of a compact oral nutrition supplement with the medication round was accepted by residents. Its efficacy in improving malnutrition risk and body composition among residents warrants further investigation.

    Nutrient Dense, Low-Cost Foods Can Improve the Affordability and Quality of the New Zealand Diet-A Substitution Modeling Study
    (MDPI (Basel, Switzerland), 2021-07-27) Starck CS; Blumfield M; Keighley T; Marshall S; Petocz P; Inan-Eroglu E; Abbott K; Cassettari T; Ali A; Wham C; Kruger R; Kira G; Fayet-Moore F
    The high prevalence of non-communicable disease in New Zealand (NZ) is driven in part by unhealthy diet selections, with food costs contributing to an increased risk for vulnerable population groups. This study aimed to: (i) identify the nutrient density-to-cost ratio of NZ foods; (ii) model the impact of substituting foods with a lower nutrient density-to-cost ratio with those with a higher nutrient density-to-cost ratio on diet quality and affordability in representative NZ population samples for low and medium socioeconomic status (SES) households by ethnicity; and (iii) evaluate food processing level. Foods were categorized, coded for processing level and discretionary status, analyzed for nutrient density and cost, and ranked by nutrient density-to-cost ratio. The top quartile of nutrient dense, low-cost foods were 56% unprocessed (vegetables, fruit, porridge, pasta, rice, nuts/seeds), 31% ultra-processed (vegetable dishes, fortified bread, breakfast cereals unfortified <15 g sugars/100 g and fortified 15–30 g sugars/100 g), 6% processed (fruit juice), and 6% culinary processed (oils). Using substitution modeling, diet quality improved by 59% and 71% for adults and children, respectively, and affordability increased by 20–24%, depending on ethnicity and SES. The NZ diet can be made healthier and more affordable when nutritious, low-cost foods are selected. Processing levels in the healthier, modeled diet suggest that some non-discretionary ultra-processed foods may provide a valuable source of low-cost nutrition for food insecure populations.
