Perception of Functional Foods After a Brief Educational Intervention: A Pilot Study in Portuguese Adults
Year: 2025
Type: article
Abstract: Functional foods have generated growing interest due to their potential in promoting health and preventing disease. However, public perception and knowledge of these products may influence their acceptance and consumption. This observational cross-sectional study aimed to assess the perception of functional foods among adults living in Portugal, before and after a brief educational intervention. Data were collected between May 2 and July 1, 2024, through an online questionnaire using snowball sampling. A total of 102 participants aged 18 years or older took part, mostly female (77.5%), single (66.7%), and residing in the urban area of Lisbon (88.2%). Prior to the intervention, 62.7% reported having heard of functional foods, and 52% stated they knew what functional foods were. Following the theoretical explanation, there was a decrease in agreement with the statements that functional foods “repair damage caused by an unhealthy diet” (p = 0.047) and “improve well-being” (p < 0.001), and an increase in agreement regarding the possibility of “undesirable effects” (p = 0.002). Although there is familiarity with the concept, notable gaps in knowledge remain. These findings underscore the need for more effective and tailored educational strategies.
