Functional food products can supplement a balanced diet for older adults by providing extra protein and fiber, supporting healthy aging and promoting favorable gut microbiota profiles. However, the texture, portion size, packaging, and ease of preparation need to be taken into consideration, without stigmatizing branding/presentation, while cost and availability are important factors. Sugar is perceived as the enemy while plant-based proteins are welcomed.
Providing Mediterranean Diet (MD) nutrients in a minimally-processed functional food product may support healthy ageing, mediating favourable gut microbiota profiles when MD adherence is challenging. We thematically analysed stakeholders' perspectives of functional food products targeting healthy ageing, through semistructured individual and group interviews in Ireland, with 47 older-adults (recruited through social, retirement and disease-support groups); and 26 HCPs across a range of disciplines. Functional food products could provide a boost of hard-to-reach nutrients, supplementary fibre and/or protein, but there is caution with silver bullet products. Changing dentition (texture), appetite (portion size), dexterity (packaging; preparation ease) must be reflected, without stigmatising branding/presentation, while cost and availability were considered important. It was perceived that sugar is the enemy, while plant-based proteins were welcomed. In summary, novel food products could supplement, but not replace, a balanced diet for older adults, providing additional protein and fibre in a convenient, sustainable, carefully branded product.
