Clinical Trial Summary

This is a randomized controlled trial to examine whether personalized guidance to increase the consumption of fiber rich food items according to the Dutch dietary guidelines, compared to usual care, improves health of individuals with type 2 diabetes.

Description:

Previous interventions with fibre supplements show promising results among individuals with type 2 diabetes, but wether these effects are similar when higher fiber intake is achieved through diet and not through supplements remains unclear.

The primary objective of this study is to investigate the effects of personalized dietary guidance to increase the intake of fibre-rich foods, as recommended in the Dutch dietary guidelines, on cardiometabolic risk profile in individuals who have type 2 diabetes, compared to usual care after six months.

The study is a parallel randomized trial over a period of twelve months, including an intervention period of six months and a follow up period of six months. The study population consists of adults with non-insulin-dependent type 2 diabetes, diagnosed by a medical doctor at least 6 months prior to study enrolment.

Secondary	Cardiometabolic risk profile (DIAL risk score)	The change in cardiovascular risk based on observed changes in HbA1c, LDL-cholesterol and systolic blood pressure. DIAL risk score ranges from 0 to 100%, with higher scores indicating a higher risk.	Change from baseline at 12 months
Secondary	Body weight (in kilograms)	As measured with a digital scale	baseline, 6 months, 12 months
Secondary	Body mass index (kg/m^2)	Weight and height will be combined to report BMI in kg/m^2.	baseline, 6 months, 12 months
