"We eat exactly what we are." Turning the words of the philosopher Feuerbach on their head, not only does what we eat affect our bodies, but our bodies also affect what we eat. The Department of Endocrinology at the Federico II University of Naples is currently publishing the results of a review of 43 studies conducted over the past decade. According to these results, food preferences are determined more by biological sex and age than by geography and culture. In particular, in a recent study published in Nutrition & Food Science by the Department of Human Sciences and Promotion of Quality of Life of the San Raffaele Telematic University of Rome, the eating behaviors of 2,021 adults were evaluated, of which 1,276 women, using a questionnaire consisting of 12 questions on eating habits, 17 on food tastes and 4 on healthy eating. The findings revealed that women consume more carbohydrates, fruits and vegetables, and less fat than men, who consume more foods high in fat and salt.
