(A) The CIA of the FFQ PCA and microbiota PCA, where the arrows relate the position of the samples in the FFQ dataset in relation to the microbiota dataset. (B) The FFQ item category associated with the visualized trends. Green dots represent fruits and vegetables, orange represents grains, cereals and bread, brown represents meats, cyan represents fish, yellow represents dairy products, blue represents sweets, cakes and alcohol, and grey represents vitamins, minerals and tea. The food items on the most extreme ends are labelled. (C) The microbial taxa at family level associated with visualized trends. The taxa present at the extreme ends are labelled. CIA: co-inertia analysis; FFQ: Food Frequency Questionnaire; PCA: principal component analysis.
