Maternal Intake of Polyunsaturated Fatty Acids in Autism Spectrum Etiology and Its Relation to the Gut Microbiota: What Do We Know?

Maternal food habits and gut microbiota composition have potential effects on fetal neurodevelopment, impacting Autism Spectrum Disorder (ASD). Our research aims to outline the relationship that ingestion of polyunsaturated fatty acids (PUFAs) and the composition of maternal gut microbiota have with the possible development of ASD in offspring. We suggest that genetic factors could be related to the different conversions between unsaturated fatty acids according to sex and, mainly, the impact of the pregnancy diet on the higher or lower risk of neurological impairments. The proportion of the phyla Firmicutes/Bacteroidetes is high with an increased consumption of linoleic acid (LA, n-6 PUFA), which is associated with maternal intestinal dysbiosis and consequently starts the inflammatory process, harming myelinization. In contrast, the consumption of α-linolenic acid (ALA, n-3 PUFA) tends to re-establish the balance of the maternal microbiota with anti-inflammatory action. Moreover, human observational studies showed a strong correlation between the consumption of n-3 PUFA, mainly above 340 g of fish per week, with beneficial effects on infant neurodevelopment. Therefore, we suggest that the proper intake of foods rich in n-3 PUFAs and their supplementation during pregnancy until lactation has an impact on reducing the development of ASD. Controlled studies with n-3 PUFA supplementation are still necessary to verify the ideal dose and the best form of administration.

Adiposity Metabolic Consequences for Adolescent Bone Health.

Infancy and adolescence are crucial periods for bone health, since they are characterized by intense physical growth and bone development. The unsatisfactory acquisition of bone mass in this phase has consequences in adult life and increases the risk of developing bone diseases at more advanced ages. Nutrient deficiencies, especially calcium and vitamin D, associated with a sedentary lifestyle; lack of sun exposure; and epigenetic aspects represent some of the main risk factors for poor bone quality. In addition, recent studies relate childhood obesity to impaired bone health; however, studies on the adiposity effects on bone health are scarce and inconclusive. Another gap concerns the implications of obesity on child sexual maturity, which can jeopardize their genetic potential bone mass and increase fracture risk. Therefore, we reviewed the analyzed factors related to bone health and their association with obesity and metabolic syndrome in adolescents. We concluded that obesity (specifically, accumulated visceral fat) harms bones in the infant-juvenile phase, thereby increasing osteopenia/osteoporosis in adults and the elderly. Thus, it becomes evident that forming and maintaining healthy eating habits is necessary during infancy and adolescence to reduce the risk of fractures caused by bone-metabolic diseases in adulthood and to promote healthy ageing.

Dissatisfaction about body image and associated factors: a study of young undergraduate students.

OBJECTIVE: To verify the prevalence of dissatisfaction with body image and its association with socio-demographic, economic, and anthropometric variables, as well as levels of physical activity among undergraduate students. METHODS: A cross-sectional study was conducted with 348 undergraduate students at the dining hall of a public Brazilian university located in the state of Mato Grosso do Sul. Body image perception was evaluated using the Silhouette Matching Task. The other variables assessed were sex, age, marital status, housing conditions, socioeconomic class, weight, height, waist circumference and physical activity levels. Multinomial logistic regression was performed to verify the association between the dependent and independent variables. RESULTS: Of the interviewees, 55.7% were men. The prevalence of dissatisfaction with body image was 59.8% among men and 55.2% among women. Dissatisfaction for being overweight, between men and women, was higher in overweight individuals when compared to normal weight individuals, according to the body mass index, and also higher in those at risk for cardiovascular disease when compared to those who were not at risk. The dissatisfaction for being thin was higher among women with low weight when compared to normal weight women, according to body mass index. There was no association between dissatisfaction for being thin and the variables analyzed among men. CONCLUSION: The prevalence of dissatisfaction with body image was observed in more than half of the individuals evaluated and is associated with nutritional status. Knowing the consequences of dissatisfaction with body image helps highlight the need for intervention strategies to avoid the practice of unhealthy behaviors.

Nutraceutical and Medicinal Potential of the Morus Species in Metabolic Dysfunctions.

Many populations use medicinal plants as a therapeutic treatment, due to their lower cost and greater access. Among the plant species used for medicinal purposes are those of the genus Morus. The most known species are Morus alba, rubra, and nigra. This review aims to collect data from the literature, predominantly from cell and animal studies, which presents a possible nutraceutical and medicinal potential of the species Morus for use in metabolic dysfunctions. The fruits and leaves of mulberry are used for therapeutic purposes. For scientific confirmation of these effects, they were studied for laxative properties, antibacterial activity, anti-atherogenic activity, and hepatoprotective function. Furthermore, the genus Morus is recognized for the treatment and prevention of diabetes mellitus, through its hypoglycemic action. It may also provide health benefits through immunomodulatory, anti-inflammatory, and anti-nociceptive effects. It has been found that the Morus species have phenolic compounds, flavonoids, and anthocyanins that act as important antioxidants and promote beneficial effects on human health. These phytochemical compounds differ among species. Blackberry (Morus nigra) are rich in flavonoids, while the white mulberry (Morus alba) has low concentrations of flavonoids and anthocyanins. In addition, another important factor is to ensure a complete exemption of toxic risks in the use of medicinal plants for the treatment of diseases. Studies have shown no toxic effects by the administration of extracts of Morus species. Thus, the mulberry tree presents nutraceutical potential. It is therefore a promising alternative for medicinal products based on medicinal plants.

RESUMO Objetivo: Verificar a prevalência de insatisfação com a imagem corporal e sua associação com variáveis sociodemográficas, econômicas, antropométricas e atividade física de universitários. Métodos: Estudo transversal, realizado com 348 universitários que frequentavam o restaurante universitário de uma universidade pública no Estado do Mato Grosso do Sul. A percepção da imagem corporal foi avaliada pelo Silhouette Matching Task. As demais variáveis avaliadas foram sexo, idade, condição marital, condição de moradia, classe econômica, peso, estatura, circunferência da cintura e nível de atividade física. Para verificar a associação entre as variáveis dependente e independente, foi realizada regressão logística multinomial. Resultados: Dentre os entrevistados, 55,7% eram homens. A prevalência de insatisfação com a imagem corporal foi de 59,8% entre os homens e de 55,2% entre as mulheres. A insatisfação pelo excesso de peso, entre homens e mulheres, foi maior nos indivíduos com excesso de peso, quando comparados aos eutróficos, segundo o índice de massa corporal, e também maior naqueles com risco para doenças cardiovasculares, quando comparados aos que não apresentaram risco. A insatisfação pela magreza foi maior entre as mulheres com baixo peso quando comparadas às eutróficas, segundo o índice de massa corporal. Entre os homens, não houve associação da insatisfação com a magreza e as variáveis estudadas. Conclusão: A prevalência da insatisfação corporal foi registrada em mais da metade dos indivíduos avaliados e esteve associada ao estado nutricional. Sabendo das consequências da insatisfação corporal, vale destacar a necessidade de estratégias de intervenção, no sentido de evitar a prática de condutas comportamentais não saudáveis.
