  • Functional food components, intestinal permeability and inflammatory markers in patients with inflammatory bowel disease
    Publication . Lacerda, Joana Franco; Lagos, Ana Catarina; Carolino, Elisabete; Silva-Herdade, Ana Santos; Silva, Manuel; Guerreiro, Catarina Sousa
    Inflammatory bowel diseases (IBD) are characterized by a chronic inflammatory process that affects the intestinal barrier structure. Recent evidence suggests that some food components can influence the integrity of the intestinal barrier and thus its permeability. We aimed at assessing the effect of food components on intestinal permeability (IP) and on inflammatory markers in individuals with IBD by a single-blind randomized clinical study. Of the 53 individuals included, 47% (n = 25) had been diagnosed with IBD. The participants were divided into 4 groups. IBD patients were allocated to intervention group (n = 14) vs. no intervention group (n = 11), and the same happened with 28 control participants without disease (n = 14 in intervention group vs. n = 14 without intervention). Symptomatology, nutritional status, biochemical parameters (specifically serum zonulin (ZO) to measure IP) were evaluated on all individuals on an eight-week period following a diet plan with/without potentially beneficial foods for the IP. At the beginning of the study, there were no significant differences in ZO values between individuals with and without IBD (p > 0.05). The effect of specific food components was inconclusive; however, a trend in the reduction of inflammatory parameters and on the prevalence of gastrointestinal symptomatology was observed. More controlled intervention studies with diet plans, including food components potentially beneficial for the integrity of the intestinal barrier, are of the utmost importance.

  • Nutrientes funcionais e resposta inflamatória em indivíduos com doença inflamatória intestinal
    Publication . Lacerda, Joana Franco; Carolino, Elisabete; Lagos, Ana Catarina; Guerreiro, Catarina Sousa
    As doenças Inflamatórias Intestinais (DII) caracterizam-se por um processo inflamatório crónico que afeta o trato gastrointestinal. Para além dos fatores ambientais, evidência recente sugere que determinados compostos alimentares (CA) podem modular a microbiota intestinal e influenciar de forma positiva, ou negativa, a resposta inflamatória, bem como o decurso destas doenças. Objetivo do estudo: Estudar o efeito da ingestão de CA nos marcadores inflamatórios em indivíduos com DII.
