Dietary habits: SFFQ, dietetic products and nutrient supplements consumption. Energy intake, macro/micronutrients (based on food composition tables), adequacy of energy and nutrients intake (percentage of the EER, NOSP, AI and UL), mineral score and diet quality index (HEISD and MDS). Adherence to guidelines for CRC prevention (PA/PE, dietary fiber, red meat and processed meat, alcoholic beverages and BMI) (subsample randomly selected). |
