 Dietary intake of adolescent and adult Lifelines participants was assessed with a food frequency questionnaire (FFQ) that was specifically developed for Lifelines to assess dietary risk factors for a considerable number of diseases. Dietary intake of adolescent and adult Lifelines participants was assessed with a food frequency questionnaire (FFQ) that was specifically developed for Lifelines to assess dietary risk factors for a considerable number of diseases.
 Since this resulted in a long and time-consuming questionnaire,​ the questionnaire was divided into four parts and called the **Flower Food Frequency Questionnaire**.\\ Since this resulted in a long and time-consuming questionnaire,​ the questionnaire was divided into four parts and called the **Flower Food Frequency Questionnaire**.\\
-The questionnaire consists of one basic questionnaire,​ assessed at [[1A|baseline]]:​ **the heart** of the flower. It  covers energy and macronutrient intake and takes ~30 minutes to complete. The raw data from the heart FFQ were used to calculate [[FFQ sum scores|nutritional ​sum scores]].\\\\ +For more information about the rationale for and validation of the flower FFQ see {{ :​flower_ffq_nutrients.pdf |Brouwer-Brolsma et al.
