Kombucha como alimento potencialmente psicobiótico / Kombucha as a potential psychobiotic food

Os casos de transtorno de ansiedade têm apresentado crescimento considerável desde o início do século XX, onde a terapia medicamentosa oferecida, geralmente apresenta efeito sedativo, portanto, a busca por tratamentos adjuvantes para tratar quadros de ansiedade se fazem necessários. Estudos indicam que a modulação da microbiota intestinal pode estar relacionada à regulação neural dos indivíduos através de diversas vias, incluindo a aplicação de cepas probióticas e consumo de alimentos fermentados tradicionais como iogurte e kombucha, colaborando para a melhoria da qualidade de vida destes pacientes. Este projeto teve como objetivo buscar os metabólitos e neurotransmissores presentes no kombucha a fim de verificar seu potencial psicobióticos e comparar as aplicações e metabólitos produzidos por cepas probióticas existentes no mercado e em alimentos fermentados tradicionais que atuem no eixo intestino-cérebro. Foram realizadas pesquisas em bases de dados online, como Pubmed, Web of Science, Scielo, Scopus e Google Scholar no período entre 2002 e 2022 relacionados aos possíveis efeitos dos probióticos em condições de ansiedade, bem como como os mecanismos que envolvem o eixo cérebro-intestino, seja por meio de testes em humanos e em modelos animais. As espécies mais testadas quanto ao seu potencial probiótico e ação nos transtornos de ansiedade encontradas foram Lactobacillus paracasei, L. casei, L. rhamnosus, Bifidobacterium infanti e B. longum. Cada gênero demonstra um grau diferente na redução da ansiedade dos indivíduos. Os alimentos potencialmente probióticos, incluindo alimentos fermentados tradicionais, além de atuar como complemento à terapia em quadros de ansiedade, tem relevância no setor socioeconômico

Anxiety disorder cases have shown considerable growth since the beginning of the 20th century, where the drug therapy offered usually has a sedative effect. Therefore, the search for adjuvant treatments to treat anxiety disorders is necessary. Studies indicate that the modulation of the intestinal microbiota may be related to the neural regulation of individuals in several ways, including the application of probiotic strains and consumption of traditional fermented foods such as yogurt and kombucha, contributing to the improvement of the quality of life of these patients. This project aimed to identify and compare the psychobiotic effect in the gut-brain axis of the metabolites and neurotransmitters produced by kombucha and commercial probiotic strains. The research was carried out in online databases, such as Pubmed, Web of Science, Scielo, Scopus, and Google Scholar in the period between 2002 and 2022 related to the possible effects of probiotics in anxiety conditions as the mechanisms that involve the brain-gut axis either through tests in humans or animal models. The species most tested for their probiotic potential and action on anxiety disorders were Lactobacillus paracasei, L. casei, L. rhamnosus, Bifidobacterium infanti, and B. longum. Each genus demonstrates a different degree of reducing individuals' anxiety. Potentially probiotic foods, including traditional fermented foods, acting as a complement to therapy in cases of anxiety, have relevance in the socioeconomic sector

Nutritional Evaluation of Traditional Fermented Foods by Dietary Intake of University Students in Chungnam

The purpose of this study was to evaluate nutritional value of traditional fermented foods by dietary intake of university students living in Chungnam. 210 students were asked for their daily food intake using 24-hour recall method for 3 days. And daily nutrient intakes from total foods and fermented foods were analyzed and compared. The mean weight, height, and BMI of the subjects were 67.36kg, 174.39cm, 22.15kg/m2 in men and 53.45kg, 161.86cm, 20.40kg/m2 in women, respectively. The daily intakes of protein, phosphorus, and vitamin B1 were 106.82%, 137.88%, and 108.99% of the Korean RDA. However, the energy, calcium, iron, vitamin A, vitamin B2, niacin, vitamin C intakes did not reached the RDA for Koreans. The fermented food intake was 9.09% of total food intake. And the percentages of fermented food intakes were 81.53% for Kimchi and 14.75% for Chang. The vegetable protein, vegetable oil, dietary fiber, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B1, vitamin B2, niacin and vitamin C intakes per 1000kcal consumption from fermented foods were significantly higher than those from total foods. The fermented food intake showed positive correlation with iron, and plant iron intakes. In conclusion, the percentage of fermented food intake was about 9% and the major items were Kimchi and alcoholi beverages in university students. Fermented food intake may be important to improve the intakes of calcium, iron and vitamin.
