Plant-based protein for sustainability and healthy aging (VG24004)
Project start date: 20/06/2025
Project completion date: 11/02/2028
Summary:
This project is providing robust evidence to support the role of vegetable/plant-based protein diets on muscoskeletal outcomes in older adults and a clear understanding of sensory drivers, barriers and motivators for adoption of vegetable/plant-based protein diets among key stakeholders.
In older Australians, increasing vegetable intake and transitioning towards more vegetable/plant-based protein diets (i.e. protein transition), as aligned with their preferences for sustainable diets, holds significant potential for improving human and environmental health.
Barriers to this transition include the perceived negative impact of vegetable/plant-based protein diets on muscle health and changes in sensory perception of older consumers in the community as well as aged care. Foundational evidence addressing these barriers will increase knowledge, awareness and attitudes towards a sustainable vegetable/plant-based protein transition and drive vegetable demand.
To succeed, the project team will assess:
- Associations of vegetable/plant-based protein diets on muscoskeletal outcomes in older Australians
- Sensory, biological, and physiological factors driving satisfaction and consumption of vegetable/plant-based protein diets
- The efficiency of vegetable/plant-based protein diets on muscle health
- Barriers and motivators for adoption of vegetable/plant-based protein diets among key stakeholders
The project team will execute cross-sectional/prospective, human intervention, and sensory studies, using cutting-edge methodologies. By generating evidence-based insights and promoting informed adoption of vegetable/plant-based protein diets, the project will help position vegetables as a critical component of healthy diets for older adults, encouraging increased consumption and long-term demand.
Findings will be shared via scientific and trade journals, industry and aged-care communications (newsletters, social media, websites), and presentations at conferences, ensuring broad reach and impact.
