 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|macronutrient sum scores]].\\ The questionnaire consists of one basic questionnaire, assessed at [[1A|baseline]]: **the heart** of the flower.
