Taste sensitivity and lifestyle are associated with food preferences and BMI in...
Rodrigues, L; Silverio, R; Costa, AR; Antunes, C; Pomar, C; Infante, P; Conceição, C; Amado, F; Lamy, EOral food perception together with lifestyle may affect food preferences and choices, influencing weight gain and obesity development. The present study was designed to evaluate the association of biological (taste sensitivity) and lifestyle variables with children food preferences, assessing whether all these variables contribute to explain BMI percentile. After anthropometric evaluation, 387 children were cla...
Changes in salivary protein composition of lambs supplemented with aerial parts...
Lamy, Elsa; Rodrigues, Lenia; Gurreiro, O; Soldado, D; Amado, F; Monica, Lima; Capela e Silva, F.; Lopes, Orlando; Santos-Silva, J; Jerónimo, ECistus ladanifer L. is a shrub present in Mediterranean areas without major use, but which can be incorporated into ruminant diets, improving the digestive efficiency of dietary protein and product quality. The high levels of plant secondary metabolites, including condensed tannins, may be responsible for the beneficial properties of the plant, but can also reduce palatability. In this study, C. ladanifer was i...
Effects of hyperleptinemia in rat saliva composition, histology and ultrastruct...
Lamy, Elsa; Neves, S; Ferreira, J; Rodrigues, Lénia; da Costa, G; Cordeiro, C; Fialho, Luisa; Lima, Mónica; Costa, Ana R.; Antunes, Célia M.OBJECTIVE: To study the effect of the satiety hormone, leptin, in saliva proteome and salivary gland histology and ultrastructure. DESIGN: Increases in blood leptin levels were induced through mini-pump infusion in male Wistar rats, during a period of 7 days. Saliva was collected before and at the end of the experimental period, for proteomic analysis, and major salivary glands were collected, at the end, for b...
Salivary proteome and glucose levels are related with sweet taste sensitivity i...
Rodrigues, Lenia; da Costa, G; Cordeiro, C; Pinheiro, Cristina; Amado, F; Lamy, ElsaSweet taste plays a critical role in determining food preferences and choices. Similar to what happens for other oral sensations, individuals differ in their sensitivity for sweet taste and these inter-individual differences may be responsible for variations in food acceptance. Despite evidence that saliva plays a role in taste perception, this fluid has been mainly studied in the context of bitterness or astri...
Relationship between saliva protein composition and 6-n-prophylthiouracyl (PROP...
Rodrigues, Lénia; da Costa, G; Cordeiro, C; Pinheiro, Cristina; Amado, F; Lamy, Elsa6‐n‐propylthiouracil (PROP) is widely used in nutritional and health studies. However, only a limited number of studies have compared saliva composition between PROP taster phenotypes. The main aim of this work was to assess the relationship between saliva proteome and PROP responsiveness in young adults (N = 152) taking into account body mass index (BMI) and sex. SDS‐PAGE and 2‐DE protein profiles of saliva co...
Effects of high fat diet on salivary alpha-amylase serum parameters and food co...
Rodrigues, L; Mouta, R; Costa, AR; Pereira, A; Capela e Silva, F; Amado, F; Antunes, CM; Lamy, ESalivary a-amylase, a major protein in saliva, has been described as a marker for sympathetic nervous system activity, hence for metabolic energy balance. In this context, its expression in overweight and obesity is of interest. Rats fed with a diet enriched with sunflower oil differentially gained weight yielding two subgroups according to their susceptibility (OP) or resistance (OR) to obesity. Elevated plasm...
