Letters in Functional Foods publishes original research articles, short communications, letters and mini-reviews. In addition, thematic issues are also published. The latest researches in healthy foods and biologically active food ingredients are of particular interest along with nutritional and technological aspects related to the development of functional foods and beverages. Studies on the use of supplements, food ingredients and naturally functional food and their relationship with consumer health are also welcomed.
