Brief Summary
This study addresses the challenge of increasing compliance with dietary recommendations and guidelines among diabetes type 2 patients by introducing professional dietary advice based on individual requirements. The objective of this study is to assess the effect of the Personalized Dietary Advice Services (PDAS) after a three month intervention on established markers of nutritional and health status in diabetes type 2 patients (HbA1c, glucose, insulin). Besides, the effect of the PDAS on perceived health status of diabetes type 2 patients will be assessed.

Study Arms (2)
Personalized advice
EXPERIMENTALDietitian provides Personalized dietary advice (based on genetic, blood and food intake profiles) (the type of advice is the intervention)
Regular care
ACTIVE COMPARATORDietitian provides regular care for diabetes type 2 (regular advice is the control condition)
Interventions
This Personalized Dietary Advice is based on markers for nutrition status and SNPs (single nucleotide polymorphisms). This advice is given via Personalized Dietary Advice Services, in which health data of the client can be entered and will be translated into advice on intake of specific nutrients or food categories.
The control group will receive usual advice for diabetes type 2 from the dietician. However, after the end of the study participants in the control group will be offered the opportunity to receive the Personalized Dietary Advice from their dietician, as based on the parameters measured during the study.
