- Fibre-UP tool: digital, personalized dietary advice to increase dietary fiber intake
- description
- Subjects will receive personalized dietary advice (PDA) based on their habitual food pattern (as assessed using a food frequency questionnaire) and preferences. Based on a previously developed algorithm, the PDA provides fiber-rich alternatives for currently used low-fiber products, close to subjects' current eating behavior, to help increase dietary fiber intake. This PDA will be provided using an online web-portal.

- Vegetable product (dried chicory root) to increase dietary fiber intake
- description
- Subjects will consume 2 sachets with each 7.5 g of dried cubes of chicory root, which equals a total of 12.3 g of dietary fiber per day. Subjects can choose when and how they consume the vegetable product, for example sprinkle it over their meal, or include in existing recipes.
