The Dutch Healthy Diet index¹⁾ is a diet score derived from one of the FFQ processing steps; the FFQ item results. This DHD index is available for ~144.000 adult participants for the FFQ heart and ~68.500 for the FFQ heart and petals (section: Nutrition (Diet scores) and Secondary & linked variables).
The DHD index was developed by researchers from Wageningen University and Research and is a tool to assess participants' coherence to the Dutch Healthy Diet index. On the Lifelines data, the Lifelines Diet Score has been developed as well, which is a tool to assess relative diet quality to the overall Lifelines population.

The DHD index will soon be available for request in the Lifelines catalogue or by email (data@lifelines.nl). When this data has been used in your research, you will have to include a reference to the the following paper:
