RESUMO

In recent years, natural polysaccharides (PSs) have attracted increasing interest because of their remarkable biological properties and potential in various areas, such as medicine, and food. This study aimed to present a detailed review of the evidence on the therapeutic potential of PSs for the treatment of gastrointestinal diseases. The main evidence was correlated with their chemical composition, mechanism of action and therapeutic effect. The main results showed that the action can be attributed to their ability to suppress excessive inflammatory responses, regulating the expression of cytokines and interleukins, reducing intestinal inflammation and promoting wound healing. Furthermore, we discussed how PSs help in the repair of the intestinal mucosa and related these effects with the composition of monosaccharides. A detailed analysis was performed on the ability of PSs to modulate the intestinal microbiota, promoting the growth of beneficial bacteria and suppressing inflammatory bacteria, in addition to its probiotic action with production of short-chain fatty acids. All this evidence was also taken into a broader context, in which the main challenges in processing PSs were considered and strategies to circumvent them were pointed out. Therefore, this review sought to demonstrate the great potential and viability of PSs as innovative and effective therapeutic agents.
