Intestinal parasitic infections (IPI) are one of the major causes of morbidity and mortality worldwide, affecting over a billion people. It is common in regions with poor living conditions, poor sanitation, limited access to safe drinking water, and with tropical and subtropical weather. The most common IPI are mainly caused by soil transmitted helminths (STHs) and by intestinal protozoan. The parasitology of the main gastrointestinal (GI) parasites is briefly described. Also, the interactions between host nutrition and GI parasites, including alterations of gut microbiota, inflammation, and gut permeability, are explored. The most common nutritional adverse effects of intestinal parasitic infection are further discussed. Finally, current options of treatment and prevention are provided.
