Food group consumption in an Italian population using the updated food classification system FoodEx2: Results from the Italian Nutrition & HEalth Survey (INHES) study

Abstract

Background and AimDietary habits evolve over time, being influenced by many factors and complex interactions. This work aimed at evaluating the updated information on food group consumption in Italy. Methods and ResultsA total of 8944 (4768 women and 4176 men) participants aged >18 years from all over Italy recruited in 2010–13 (Italian Nutrition & HEalth Survey, INHES) was analyzed. The recruitment was performed using computer-assisted-telephone-interviewing and one-day 24-h dietary recall retrieved from all participants. The updated, second version, of FoodEx2 food classification system was applied to extract data on food group consumption. The participation rate was 53%; 6.2% of the participants declared to follow a special diet, the most prevalent being hypo-caloric diets (55.7% of special diets). Men compared to women presented significantly higher intakes of “grains and grain-based products”, “meat and meat products”, “animal and vegetable fats and oils and primary derivatives” and “alcoholic beverages” (P for all<0.001); moreover, men had lower intakes of “milk and dairy products”, “water and water-based beverages” and “products for non-standard diets, food imitates and food supplements” (P for all<0.001). Differences in food group intake among age groups, geographical regions and educational level groups were also identified (P for all<0.05). ConclusionsData on the consumption of more than 70 food groups and sub-groups were illustrated in different strata. The present analysis could be considered as an updated source of information for future nutrition research in Italy and in the EU.
