This systematic review summarized the role of omega-3 supplementation on anthropometric markers, lipid profile, inflammation markers and glucose metabolism in the treatment of overweight/obese children and adolescents. A total of 8 randomized clinical trials were included with intervention period ranging from 8 weeks to 12 months and participant ag...

The increased demand of consumers for healthy foods has generated interest among researchers and food producers in developing functional foods. Olive pomace (OP) can be used to obtain high‐added value products, being a valuable source of phenols. The aim of the study was to assess the influence of incorporating OP extract, as free lyophilized (F‐OP...

Olive trees not only produce olives but also generate a substantial amount of waste and by-products, including leaves, pomace (the solid remains after pressing olives for oil), and wastewater from the olive oil-making process. The waste products, particularly the leaves, contain bioactive compounds, especially phenolic compounds, known for their he...

This study aimed at comparing the carbohydrate composition of three banana varieties (cv. Nanica, Nanicão, and Prata) and investigating the effect of a single dose of cooked green banana pulp beverage (GBPd) on plasma glycemic homeostasis indexes (glucose, PYY, GIP, insulin) and hunger and satiety sensation (visual analog scale-VAS). The bananas we...

Olive oil, as well as by-products and waste that are left after production, particularly olive pomace and olive leaf, have been extensively researched as sources of phenolic compounds. These compounds are known for their biological properties and have been associated with the prevention of chronic non-communicable diseases. Metabolomics has been us...

The consumption of chia seeds has become popular due to their beneficial health properties and the germination of chia seeds seems to further enhance these properties. This study aimed to evaluate the changes in the nutritional composition of chia seeds after germination for 3 and 6 days. Chemical composition, fatty acid profile, phenolic content a...

This study aimed to evaluate the hepatic antioxidant activity of a high-fat diet supplemented with chia oil in mice. Forty animals were divided into Control (C, n = 10), Control + 1.5 % chia oil (CC, n = 10), High fat (HF, n = 10), and High fat + 1.5 % chia oil (HFC, n = 10) groups. Chia oil reduced serum triacylglycerol in the HF group (p

Chia (Salvia hispanica L.) is a seed native to northern Mexico and southern Guatemala that has started to be consumed in recent years in other regions of the world owing to its nutritional and functional properties. Germination of chia seeds seems to be able to further improve these properties, and it has been the subject of some studies. In genera...

We aimed to evaluate the acceptance of artisanal ice cream prepared with extra virgin olive oil (EVOO) as the main lipid ingredient. Two formulations were developed using an EVOO from Brazil (BrEVOO) and another from Greece (GrEVOO), both with high content of phenolics. Acceptance test using a hedonic scale was applied. Principal component analysis...

O agravamento do estado nutricional durante a internação hospitalar, afeta negativamente o estado clínico do paciente, pois, podem ocorrer alterações fisiológicas oriundas de um processo adaptativo do organismo à escassez de nutrientes. Nesse sentido, o presente artigo teve por objetivo discutir estratégias de gastronomia hospitalar voltadas para a...

Objective This study aimed to develop two non-industrial food products as financially accessible options to prevent and treat malnutrition in hemodialysis (HD) patients. These food products were developed and intended for use as dialysis snacks. Methods This is a cross-sectional and multi-step study. First, 183 adult HD patients (55 ± 14 years; 50...

Brazil is an emerging virgin olive oil producer country whose oils have been scarcely studied till now and, in particular, no data are present in literature about their volatile profiles and organoleptic characteristics as well as the Pearson's correlations between chemical and sensory parameters. Hence, giving insights about these aspects was the...

Objective: Chia seed oil is the richest source of plant-based ω-3 fatty acid, α-linolenic acid, but its potential and mechanisms of action to treat obesity are unclear. The aim of the study was to evaluate the effects of chia oil (ChOi) supplementation on body composition and insulin signaling in skeletal muscles of obese mice. Methods: Male C57...

Green banana flour shows good potential as a functional ingredient for special-purpose foods, but there are no data in the literature concerning the use of a green banana pulp and peel flour for the development of products such as pasta. The aim of the present study was to develop tagliatelle pasta substituting the wheat flour with different concen...

Background: Flaxseed is becoming an increasingly widely used food ingredient. The rising interest of the food industry in this nutraceutical is primarily because of functional nutrients, such as alpha-linolenic acid and lignans, which have health benefits due to their lipid-lowering properties. Objective: The objective of this study was to provi...

A promoção de hábitos alimentares saudáveis no ambiente escolar pressupõe o desenvolvimento de atividades educativas que ajudam e motivam a adoção de uma alimentação saudável. Dessa forma, o objetivo deste trabalho foi realizar ações de educação alimentar e nutricional em estudantes e funcionários de uma escola municipal da cidade do Rio de Janeiro...

Introducao: A doenca celiaca e uma enteropatia autoimune causada em individuos com intolerância ao gluten, podendo resultar na ma absorcao de nutrientes. O tratamento consiste em uma dieta isenta desta proteina, conduzindo os celiacos a monotonia alimentar; assim, a doenca celiaca tem sido objeto de estudos em busca de alternativas alimentares para...

This work aimed to evaluate the effects of the consumption of two commercial conjugated linoleic acid (CLA) mixtures on lipid content and liver histology of healthy rats. The investigation was carried out using thirty rats divided into three groups: C (control), AE (AdvantEdge®CLA), and CO (CLA One®). The concentration of CLA was 2% of feed consump...

Supplementation with conjugated linoleic acid may reduce fat body mass and increase lean body mass in various species. Some studies have demonstrated that conjugated linoleic acid reduces body fat, in part, by inhibiting the activity of lipoprotein lipase in adipocytes. The objective of this work was to study the effect of conjugated linoleic acid...

OBJETIVO:O objetivo do trabalho foi avaliar a estabilidade oxidativa de misturas comerciais de ácido linoléico conjugado e buscar possível correlação entre a suplementação e o conteúdo total de lípides hepáticos, e também de alguns indicadores da oxidação lipídica em ratos. MÉTODOS:Um ensaio biológico com 30 ratos divididos em três grupos (n=10) ca...

Dietary supplementation with conjugated linoleic acid (CLA) may reduce body fat mass and increase lean body mass in various species. The objective of this study was to study the effects of conjugated linoleic acid (CLA) supplementation on body composition, serum leptin and triacylglycerol levels in Wistar rats.
