| Resumo: | The gut microbiota (GM) is responsible for several functions that enable body homeostasis.
Its colonization occurs from birth and varies until senescence. GM is composed of several
microorganisms, with a predominance of bacteria. Habits such as poor diet, alcohol and drug
consumption, as well as lack of physical exercise can trigger GM imbalances. In this sense,
diet emerges as one of the main modulating factors of human IM. Despite the evidence, there
is a scarcity of studies that compile data on the effects of dietary patterns on GM, especially in
Portuguese. In this sense, this work aimed to carry out a narrative review on this topic. To
better support the review, a search was carried out for observational studies and clinical trials
published in the last 5 (2019 to 2023) years and indexed in the PubMed/MEDLINE database.
We observed that each dietary pattern acts in a different way on GM, interfering with bacterial
composition and diversity. Only the Western dietary pattern allowed negative effects on GM,
due to the large amount of ultra-processed foods ingested. All other patterns had beneficial
effects on GM, especially because their high content of fiber from fruits and vegetables,
which enables an increase in the production of short chain fatty acids (SCFA). It is expected
that more studies will be carried out on this topic and that there will be advances in relation to
the modulation of GM through the adoption of specific dietary patterns for the prevention,
control or treatment of various clinical conditions. |
