The Bidirectional Link between Nutritional Factors and Inflammatory Bowel Diseases: Dietary Deficits, Habits, and Recommended Interventions-A Narrative Review.

Inflammatory bowel diseases comprise Crohn's disease and ulcerative colitis, two chronic inflammatory disorders of the digestive tract that develop in adolescence and early adulthood and show a rising pattern in industrialized societies, as well as in developing countries, being strongly influenced by environmental pressures such as nutrition, pollution and lifestyle behaviors. Here, we provide a narrative review of the bidirectional link between nutritional factors and IBD, of dietary deficits observed in IBD patients due to both the disease itself and dietary habits, and of the suggested nutritional interventions. Research of the literature was conducted.

What Has Changed over Years on Complementary Feeding in Italy: An Update.

Current practice regarding complementary feeding (CF) is influenced by socio-cultural background. Our group already investigated the Italian approach to CF in the years 2015-2017. Our aim was to update those data by finding out: if the habits have changed nationwide, how the trends changed in each area, and if the differences between regions still exist.

Dietary Habits and Nutrient Deficiencies in a Cohort of European Crohn's Disease Adult Patients.

Wrong dietary habits, such as the Western-style diet, are considered important risk factors for the development of Inflammatory Bowel Diseases (IBDs). Nevertheless, the role of dietary patterns in the clinical management of IBD patients has not been fully investigated yet. Fifty-four patients diagnosed with active Crohn's disease (CD) were enrolled and subjected to nutritional intake analysis through a weekly food diary.
