Time to evaluate diet quality and give dietary advice is limited in clinical IBD practice. The Eetscore is a web-based tool that assesses diet quality according to the Dutch dietary guidelines and provides personalised dietary advice. We aimed to assess diet quality of IBD patients using the Eetscore and to study changes in diet quality, health-related quality of life (HRQoL) and clinical disease activity over time. A prospective cohort study was performed in 195 adult IBD patients. Participants were invited to fill out questionnaires (Eetscore-FFQ, short IBDQ and p-HBI/p-SCCAI) at baseline and after 1 and 4 months. The Eetscore calculates diet quality based on 16 food components (10 points per component, total score 0-160; the higher the better) and provides dietary advice per component based on the assessment. At baseline, mean diet quality was 98±19. Diet quality was positively associated with age, female gender and level of education. Component scores were highest for red meat, wholegrain products, and sweetened beverages, and lowest for legumes, nuts, and processed meat. Over time, diet quality increased to 107±21 at 4 months (p<0.001). Each 10-point improvement in diet quality was associated with an increase in HRQoL (β=0.4 (95%CI 0.02; 0.7), p=0.04). Clinical disease activity did not change. In conclusion, diet quality of IBD patients significantly improved following personalised dietary advice of the Eetscore. Improvement of diet quality was associated with a slight improvement in HRQoL. The Eetscore is a practical and useful tool to monitor and support a healthy diet in IBD patients.
