Antioxidant, anti-inflammatory and anti-obesity effects of onion and its by-products in high-fat fed rodents: a systematic review.

The effects of onion and its by-products on metabolic changes induced by excessive consumption of a high fat diet have been the focus of many studies. The aim of this study was to systematically review the effects of onion and its by-products antioxidant, anti-inflammatory and anti-obesity in rats exposed to a high-fat diet. Five databases were used: Pubmed, EMBASE, Science Direct, Web of science and Scopus until June 2020 updated December 1, 2022. Research of the articles was carried out by two reviewers, searching and selecting studies after an initial reading of the titles and abstracts. In total, 2,448 papers were found and, after assessing against the inclusion and exclusion criteria, 18 papers were selected for this review. The findings of this review show the beneficial effects of onion and its by-products on inflammatory parameters, obesity, cardiovascular disease, thermogenesis and hepatic alterations generally associated with the consumption of a high-fat diet.

Perinatal exposure to a high-fat diet alters proopiomelanocortin, neuropeptide Y and dopaminergic receptors gene expression and the food preference in offspring adult rats / Exposição perinatal a uma dieta hiperlipídica altera a expressão gênica de proopiomelanocortina, neuropepitídeo Y e receptores dopaminérgicos e a preferência alimentar em ratos adultos descendentes

Exposure to the hight-fat diet may alter the control of food intake promoting hyperphagia and obesity. The objective of this study was to investigate the effects of this diet on dopamine receptors (drd1 and drd2), proopiomelanocortin (pomc), neuropeptideY (npy) genes expression, and preference food in adult rats. Wistar female rats were fed a hight-fat or control diet during pregnancy and lactation. The offspring were allocated into groups: Lactation - Control (C) and High-fat (H). Post-weaning ­ Control Control (CC), offspring of mothers C, fed a control diet after weaning; Control Hight-fat (CH), offspring of mothers C, fed a hight-fat diet after weaning; Hight-fat Control (HC), offspring of mothers H, fed with control diet after weaning; and Hight-fat Hight-fat (HH), offspring of mothers H, fed a H diet after weaning. The groups CH and HH presented greater expression of drd1 in comparison to the CC. The drd2 of CH and HC presented higher gene expression than did CC. HH presented higher pomc expression in comparison to the other groups. HC also presented greater expression in comparison to CH. The npy of HH presented greater expression in relation to CH and HC. HH and HC have had a higher preference for a high-fat diet at 102º life's day. The high-fat diet altered the gene expression of the drd1, drd2, pomc and npy, and influencing the food preference for high-fat diet.

Murinometric measurements and retroperitoneal adipose tissue in young rats exposed to the high-fat diet: Is there correlation?

AIM: This study aimed to verify the correlation between murine measurements and retroperitoneal adipose tissue in rats exposed to the high-fat diet. Material and methods: Wistar male adult rats, descendants of mothers who consumed a high-fat diet during pregnancy and lactation and fed the same diet after weaning were used. At 60 days of life, body weight, longitudinal axis and waist circumference (WC) were measured. The Body Mass Index (BMI) and the Lee Index were calculated for a posterior analysis of the correlation with the amount of retroperitoneal adipose tissue dissected on the same day. For analysis of the data, the Pearson correlation test was used, considering statistical significance for p <0.05. Results: Body weight had a weak correlation (r= 0.31; p= 0.38) with retroperitoneal adipose tissue. While the longitudinal correlated moderately and negative (r= -0.40; p= 0.25). Abdominal circumference (r= 0.62; p= 0.05), body mass index (r= 0.61; p= 0.03) and Lee (r= 0.69; p= 0.03) correlated moderately and positively with adipose tissue. Conclusion: Among the measured murine measurements, weight and longitudinal axis were not good indicators to represent accumulation of retroperitoneal adipose tissue in rats. However, Lee's index seems to be the best murine marker to diagnose the accumulation of retroperitoneal fat. BMI, CA and Lee index were murine parameters with higher correlation.

Objetivo: Este estudo teve como objetivo verificar a correlação entre medidas murinométricas e tecido adiposo retroperitoneal em ratos expostos à dieta hiperlipídica. Material e métodos: Foram utilizados ratos Wistar machos adultos, descendentes de mães que consumiram dieta hiperlipídica durante a gestação e lactação e alimentados com a mesma dieta após o desmame. Aos 60 dias de vida, foram medidos o peso corporal, o eixo longitudinal e a circunferência da cintura (CC). O Índice de Massa Corporal (IMC) e o Índice de Lee foram calculados para posterior análise da correlação com a quantidade de tecido adiposo retroperitoneal dissecado no mesmo dia. Para análise dos dados, utilizou se o teste de correlação de Pearson, considerando significância estatística para p<0.05. Resultados: O peso corporal apresentou uma correlação fraca (r= 0,31; p= 0,38) com o tecido adiposo retroperitoneal. Enquanto o longitudinal correlacionou moderadamente e negativo (r= -0,40; p= 0,25). A circunferência abdominal (r = 0,62; p = 0,05), índice de massa corporal (r= 0,61; p= 0,03) e Lee (r= 0,69; p= 0,03) correlacionaram-se moderada e positivamente com o tecido adiposo. Conclusão: Entre as medidas murinométricas, o peso e o eixo longitudinal não foram bons indicadores para representar o acúmulo de tecido adiposo retroperitoneal em ratos. No entanto, o índice de Lee parece ser o melhor indicador murinométrico para diagnosticar o acúmulo de gordura retroperitoneal. O IMC, índice de Lee e CA foram parâmetros murinométricos com maior correlação.

Effects of maternal high fat intake during pregnancy and lactation on total cholesterol and adipose tissue in neonatal rats / Efeitos do consumo materno de dieta hiperlipídica durante a gestação e lactação no colesterol total e tecido adiposo de ratos neonatos

Abstract Aim Obesity during pregnancy is one of the most established risk factors for negative long-term programming. The aim of the present study was to investigate the effects of maternal consumption of a high-fat diet during pregnancy and lactation on the weight gain, visceral adipose tissue and cholesterolemia in neonatal rats. Methods Wistar rats were divided into two groups according to the mother's diet during pregnancy and lactation: Control group (CG, n = 12) were the offspring of rats fed a standard diet (4% lipid) and the Test group (TG, n = 12) were pups rats fed on a high fat diet (23% lipid). The weight of the animals was measured on alternate days until the 22nd day of life, when collected visceral adipose tissue and blood were collected for biochemical analysis. For statistical analysis the Student t test, Sidak´s teste and two way ANOVA was used, with p <0.05. Results the test group showed differences in weight gain, visceral adipose tissue and higher cholesterol. Conclusion a maternal exposure to a high-fat diet during pregnancy and lactation can promote changes in weight gain, hypercholesterolemia and an increase in adipose tissue in neonatal rats.

Resumo Objetivo A obesidade durante a gestação é um dos fatores de risco mais estabelecidos para uma programação negativa em longo prazo. O objetivo do presente estudo foi investigar os efeitos do consumo materno de uma dieta hiperlipídica durante a gestação e lactação no aumento do peso, do tecido adiposo visceral e colesterolemia em ratos neonatos. Métodos Ratos Wistar foram divididos em dois grupos de acordo com a dieta da mãe durante a gestação e lactação: grupo controle (GC, n=12) composto por filhotes de ratas alimentadas com uma dieta padrão (lipídios 4%) e o grupo teste (GT, n=12) composto de filhotes de ratas alimentadas com dieta hiperlipídica (lipídios 23%). O peso dos animais foi aferido em dias alternados até o 22° dia de vida, quando foi coletado sangue para análises bioquímicas. Para a análise estatística utilizou-se os seguintes testes: two way ANOVA, teste de Sidak e teste t de Student, com p< 0,05. Resultados O grupo teste mostrou diferença no ganho de peso, no tecido adiposo visceral e nos níveis de colesterol. Conclusão Uma exposição materna a uma dieta hiperlipídica durante a gestação e lactação pode promover maior ganho ponderal, hipercolesterolemia e um aumento do tecido adiposo em ratos neonatos.
