Background Characterization of food lipids has triggered the development of applications for the food and health industries. Thus, the lipid profiles of an increasing number of fruits and their seeds have been characterized and numerous bioactive components have been isolated. The bitter gourd seed oil has aroused great interest because it contains relevant amounts of conjugated fatty acid α-eleostearic...

Background The objective of the study is to evaluate the influence of serum vitamin D concentrations and smoking status in cardiac structure and function. Methods The participants of this study were healthy women smokers (n = 18, mean age 52.8 years), ex-smokers (n = 18, mean age 51.7 years), and never smokers (n = 19, mean age 44.4 years). All participants underwent assessment of body composition,...

Background Preventing the development of iron deficiency anemia during infancy requires the appropriate complementary foods with high energy, nutrient density, and adequate iron content, as well as high nutrient bioavailability. We aimed to evaluate iron intake, bioavailability, and absorption from foods, in healthy infants and toddlers at a Well Child Clinic. Methods This observational, cross-sectional,...

Background Skipping meals, especially breakfast, is related to an increase in adiposity indicators, and this behavior is related to metabolic changes that predispose to the development of chronic diseases, recognized as major causes of death worldwide. The objective of the present paper was estimated the association between irregular breakfast habits with adiposity indices in schoolchildren and other...

This article aims to review glutamine metabolism and its effects on the immune response. Selected topics are addressed, particularly the effect of glutamine on cell survival and proliferation, as well as its importance in some biochemical pathways. The impact of glutamine on muscle, intestine, and liver metabolism are described, and a special section about glutamine regulation of the immune response...

Seafood lipids encompass important healthy nutrients, such as n-3 polyunsaturated fatty acids (n-3 PUFAs), which may have a significant effect on human cardiovascular health and needs to be supplied by the human diet. Particularly, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the most abundant n-3 PUFA present in seafood and have an impact on the cardiovascular health. DHA and EPA...

Background Eight Lactobacillus reuteri strains, previously isolated from breast-fed human infant feces, were selected to assess the potential contribution of their surface proteins in probiotic activity. These strains were treated with 5 M LiCl to remove their surface proteins, and their tolerance to simulated stomach-duodenum passage, cell surface characteristics, autoaggregation, adhesion, and inhibition...

Background Paraoxonase 1 (PON1) is an enzyme that possesses anti-atherogenic and anti-inflammatory properties with serum levels determined by genetic and exogenous factors. Lower serum PON1 arylesterase activity is associated to metabolic alterations related to childhood overweight and onset and/or development of diabetes and CVD later in life. However, data on the relationship between genetic PON1...

Aging is an intricate process modulated by different molecular and cellular events, such as genome instability, epigenetic and transcriptional changes, molecular damage, cell death and senescence, inflammation, and metabolic dysfunction. Particularly, protein quality control (chaperone systems) tends to be negatively affected by aging, thus leading to cellular senescence in metabolic tissues and,...

Background Overweight is a global issue of epidemic proportions, and its negative influence on individual health is clear. However, the relation between environment and overweight is not thoroughly clear, especially concerning to the perceived environment and the physical and social aspects. Therefore, this study aimed to analyze potential associations between the perceived environment and overweight...

Background The benefits of caloric restriction (CR) on the protection against age-related neurodegenerative diseases have been the subject of several studies. However, the effects of CR on the central nervous system are still poorly understood since most studies were carried out in mature animals. The present study aimed to investigate whether the age at onset of CR could differently affect the redox...

Background Health behavior theories are useful to interpret adolescents’ dietary behaviors. Evidences show that theories are influenced by social and psychological determinants. So, the purpose of this study is to systematically review studies that tested social cognitive theories (non-integrated) that predict adolescents’ dietary behaviors. Methods A structured electronic search of all publication...

Muscle mass is the major deposit of protein molecules with dynamic turnover between net protein synthesis and degradation. In human subjects, invasive and non-invasive techniques have been applied to determine their skeletal muscle catabolism of amino acids at rest, during and after different forms of physical exercise and training. The aim of this review is to analyse the turnover flux and the relative...

Position statement: The Brazilian Society for Food and Nutrition (SBAN) bases the following position statement on a critical analysis of the literature on the indications of a gluten-free (GF) diet. (1) There is insufficient evidence to assume that healthy individuals would experience any benefits from the consumption of a GF diet. (2) Recent studies suggest that gluten sensitivity may be confounded...

Background The breakfast is the most important meal of the day, and its quality is essential for children and adolescents to maintain proper health condition. However, the nutritional composition of breakfast remains poorly studied. The aim of this study was to characterize the nutritional quality of Brazilian adolescents’ breakfast. Methods This is a cross-sectional study, conducted in 2005, including...

Background The objective of this study is to evaluate the effect of protein-rich mucuna product (PRMP) on lipid parameters of hyperlipidemic rats. Methods Hyperlipidemia was induced in male rats for 3 weeks through high-fat diet. After induction, 30 hyperlipidemic rats were divided into five groups of six rats: control group (CG) received casein and four groups received PRMP as protein source at...
