What fibres do you have in MIND? Investigating personal views and intakes of dietary fibre within the ‘Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet’ in Dutch older adults at risk of cognitive decline

Dutch older adults’ fibre intakes are highly insufficient, while an adequate fibre intake is considered important in overall disease prevention. Fibres play an important role in the prevention of cardiovascular disease, metabolic diseases, and colon cancer. Moreover, recent interest has gained attention towards the preventive role of a high fibre intake for cognitive decline. The health benefits of a high fibre intake are clear, however, how to achieve a sufficient fibre intake in practice remains an unanswered question. In the FINGER-NL study, the healthful and high-fibre MIND diet is part of a 2-year multidomain lifestyle intervention aiming to reduce the risk of cognitive decline. Within the dietary domain of FINGER-NL, we aim to improve fibre intake in the long term through the MIND diet, using personal coaching and eHealth interventions. To this end, we will optimise the MIND diet to Dutch standards, explore participant perceptions towards the diet and fibre intake, investigate differences in fibre intake over time, and determine the feasibility of our strategies in a real-life setting.
