Abstract

The aim of this review is to provide an overview of the evidence to date and several key considerations regarding addressing undernutrition in older adults with plant-based products. Undernutrition, resulting from inadequate protein and energy intake is common among older adults, and is associated with poor health and quality of life. Ensuring adequate protein and energy intake is a key component of strategies aiming to prevent and/or treat undernutrition. Increasing diversity of protein intake to include more sustainable plant-based sources is encouraged in the general population. However, to support healthy ageing, it is important to consider factors such as the impact of greater consumption of plant-based products on appetite and nutritional status, muscle protein synthesis and skeletal muscle mass. Although the literature in older adults is limited, the current evidence suggests no significant differences when comparing effects of plant to animal-based products/diets on a range of outcomes including appetite, nutritional status, longer-term muscle protein synthesis and muscle mass. Furthermore, there is evidence of improvements in nutritional status and muscle protein synthesis following plant protein supplementation compared to before supplementation or lower protein intakes. Therefore, greater intake of certain plant-based products could assist in enhancing sustainability of food systems and meeting nutritional requirements to prevent undernutrition. Among other factors, the plant protein source, the food matrix and presence of other nutrients need consideration. Further studies are needed in several areas, including investigating the effects of greater intake of plant-based products on the gut microbiome, and in the treatment of undernutrition.
