Increasing individuals’ fibre intake through personalised advice


Call for partners: Increasing individuals’ fibre intake through personalised advice

The Dutch Digestive Foundation, TNO and Wageningen University & Research have joined forces within the consortium 'Personalised Nutrition and Health' to carry out research in a real-life setting into how the fibre intake of individuals can be increased by personalised advice.

Do you want to bring high-fibre ingredients or products to the market and learn how they can be best implemented into the dietary pattern of people? Please join us in this project.

The consumption of dietary fibre is positively linked to all kind of health effects, including prevention of cancer, cardiovascular disease and obesity. Moreover, it directly contributes to our digestive health, especially for people with constipation (which is almost 20% of the world's population). Despite various initiatives to stimulate dietary fibre intake in the last decade, the general intake of dietary fibre in the Netherlands is still below the recommended daily intake of 30 grams/day for women and 40 grams/day for men.

We believe that a more personal approach can effectively stimulate and motivate people to comply with a healthy diet that meets their individual needs. Therefore, together with the Dutch Digestive Foundation, we initiated this study to answer the question 'How can we increase consumers' fibre intake through personalised dietary advice?'

To generate and provide personalised dietary advice that can be combined in a SMART digital tool, various factors need to be taken into account, for instance, which (personal and dietary) input data are essential and how to provide this advice? How to come to an effective and feasible consensus is one of the biggest challenges.

Project in two stages

The project will be conducted in two phases:

1: Knowledge & nutrition advice

The first phase of the project has started in 2018. In this phase valuable digitized knowledge is obtained, that can be used in smart tools to provide consumers with personalised advice. A digital tool is developed, that is currently validated in a human intervention study including healthy people without gastrointestinal complaints. In this way knowledge is obtained if and in what form personalised nutrition advice increases fibre intake.

2: Less constipation

In the second phase, starting by the end of 2019, the project scope will be enhanced towards people with gastrointestinal complaints, focusing on people with constipation.

There is evidence that an increased fibre intake can be beneficial for health and quality of life for people with constipation. Insoluble, non-fermentable fibres are generally thought to be the best fibres to ease constipation. However, also soluble fibres , like inulin and psyllium, are reported to reduce defecation difficulties and soften stool in constipated people.

In this project the work of phase 1 will be extended. Also lessons learned on the generation and provision of a personalised dietary advice to increase fibre intake, will be implemented. Besides that the focus will be on the effect of increased fibre intake on gastrointestinal health and on wellbeing for people with constipation. The fibre intake composition is one of the elements that will be looked at.


Current partners of the project are: Bolletje, Kellogg, Sensus and Sonneveld. The project is now open for new partners who want to participate in the second stage of this living lab. We are welcoming partners who bring high-fibre ingredients or products to the market. This can be partners from food & ingredient industry but can also be partners like retail, food service etc. All data obtained in phase 1 will be open to the new partners. The Dutch Digestive Foundation will publish the collaboration on their website.


Industrial partners are asked for both an in-cash and in-kind contribution. This in-kind contribution can be in the form of products, product knowledge, internal support during advice development, equipment and hours spend on the project.
