Abstract(s)
A microbiota intestinal humana Ć© definida como a totalidade dos microrganismos presentes na superfĆcie epitelial do trato gastrointestinal humano. As suas principais funƧƵes incluem a sĆntese de aminoĆ”cidos e vitaminas, e a produĆ§Ć£o de energia a partir de polissacarĆdeos. Para alĆ©m disso, contribui para a integridade da parede intestinal, protege contra microrganismos patĆ³genicos e estimula a aĆ§Ć£o do sistema imunolĆ³gico. A relaĆ§Ć£o entre a flora intestinal e a saĆŗde global do organismo tem suscitado um interesse crescente na compreensĆ£o dos benefĆcios da manutenĆ§Ć£o e/ou modulaĆ§Ć£o da microbiota atravĆ©s do uso de probiĆ³ticos. Os probiĆ³ticos sĆ£o microrganismos vivos que, quando administrados em quantidades apropriadas, conferem benefĆcios ao organismo. Nos Ćŗltimos anos, a sua utilizaĆ§Ć£o na prevenĆ§Ć£o e/ou tratamento de doenƧas de etiologia diversa tem suscitado um grande interesse. A presente revisĆ£o bibliogrĆ”fica explora estes aspetos, procurando compreender as limitaƧƵes e potencialidades da utilizaĆ§Ć£o de probiĆ³ticos na melhoria da qualidade da saĆŗde, na atualidade e num futuro prĆ³ximo.
The human intestinal microbiota represents the microorganisms that live on the epithelial surface of the human gastrointestinal tract. Its main functions include the synthesis of amino acids and vitamins, and the production of energy from polysaccharides. In addition, it contributes to the integrity of the intestinal wall, protects against pathogenic microorganisms and stimulates the action of the immune system. The relationship between intestinal flora and health has raised a growing interest in understanding the benefits of maintaining and/or modulating the microbiota through the use of probiotics. Probiotics are living microorganisms that, when administered in appropriate amounts, are beneficial to the body. In recent years, their use in the prevention and/or treatment of diseases of diverse etiology has attracted great interest. The present bibliographic review explores these aspects, trying to understand the limitations and potentialities of the use of probiotics in the improvement of health quality, nowadays and in the near future.
