The elevated prevalence of obesity worldwide is a challenging public health problem. Dietary calcium intake is frequently below recommendations, and evidence gathered for more than a decade suggests that inadequate calcium intake may be related to increased body weight and/or body fat, although a consensus has yet to be reached. Whole-body energy balance and the cellular mechanisms involved have been proposed to explain this relationship, and increasing evidence from epidemiological, clinical, and basic research lends support to the hypothesis that calcium is linked to the regulation of body weight. This review provides a critical appraisal of evidence from studies that examined several different aspects of this issue. Different mechanisms are highlighted and, based on recent work, new perspectives are offered, which incorporate the concept of obesity-associated inflammation and the possible role of the extracellular calcium-sensing receptor.
Animal and vegetable protein in general decreased heme iron uptake. However, purified animal and vegetable protein induce an increase in heme iron uptake.
El almidón resistente es una fracción del almidón que es capaz de resistir a la digestión y se mantiene íntegro a lo largo del tracto gastrointestinal. Una de las ventajas de este almidón es que permite ser utilizado como un ingrediente que refuerza las características tecnológicas de los alimentos, además de otorgar beneficios fisiológicos asociados a la salud. De manera natural el almidón resistente podemos encontrarlo en granos de cereales, semillas, legumbres y tubérculos y en la industria alimentaria en una amplitud de productos asociados a la panificación, pastelería, galletería y cereales extruídos. Las ventajas tecnológicas de este almidón están explicadas por su microestructura, que permite obtener productos con una mejor textura, sin afectar las características de sabor, olor y color del alimento. Desde el punto vista fisiológico, el almidón resistente es capaz de modular la cinética de digestibilidad de los nutrientes, lo que posibilita su incorporación en el diseño de productos con menor índice glicémico y menor poder energético. La modulación del metabolismo de la glucosa y los lípidos, así como las posibles asociaciones con la salud de la microbiota, indican que el almidón resistente podría ser un ingrediente con un gran potencial en el tratamiento de enfermedades crónicas.
We established that human adipose cells and the human adipose cell line LS14 express the calcium-sensing receptor (CaSR) and that its activation induces inflammatory cytokine production. Also, its expression is enhanced upon exposure to obesity-associated proinflammatory cytokines. We have thus proposed that CaSR activation may be associated with adipose dysfunction. Here, we evaluated a possible effect on adipogenesis. We induced adipose differentiation of primary and LS14 human preadipocytes with or without the simultaneous activation of CaSR, by the exposure to the calcimimetic cinacalcet. Activation of the receptor for 24 h decreased by 40 % the early differentiation marker CCAAT/enhancer-binding protein β. However, upon longer-term (10 day) exposure to the adipogenic cocktail, cinacalcet exerted the opposite effect, causing a dose-response increase in the expression of the mature adipose markers adipocyte protein 2, adiponectin, peroxisome proliferator-activated receptor γ, fatty acid synthase, and glycerol-3-phosphate dehydrogenase. To assess whether there was a time-sensitive effect of CaSR activation on adipogenesis, we evaluated the 10 day effect of cinacalcet exposure for the first 6, 24, 48 h, 6, and 10 days. Our observations suggest that regardless of the period of exposure, 10 day adipogenesis is elevated by cinacalcet. CaSR activation may interfere with the initial stages of adipocyte differentiation; however, these events do not seem to preclude adipogenesis from continuing. Even though adipogenesis (particularly in subcutaneous depots) is associated with insulin sensitivity and adequate adipose function, the implications of our findings in visceral adipocytes, especially in the context of inflamed AT and overnutrition, remain to be established.
Type 2 diabetes (T2D) is directly related to alterations in iron status, oxidative stress and decreased mitochondrial activity, but the possible interaction of these parameters among T2D patients and their offspring is unclear. The whole study included 301 subjects: 77 T2D patients and one of their offspring and 51 control subjects with one of their offspring. The offspring were older than 20 years old. We measured parameters of iron status (serum iron, ferritin and transferrin receptor), diabetes (pre and post-prandial glucose, insulin, lipids), oxidative stress (Heme oxygenase activity, TBARS, SOD, GSH, Vitamin E), as well as the expression of genes in blood leukocytes related to mitochondrial apopotosis (mitofusin and Bcl/Bax ratios). The offspring of T2D patients had increased levels of serum ferritin (P < 0.01) and lower transferrin receptor (P < 0.008); higher insulin (P < 0.03) and total and LDL cholesterol; higher heme oxygenase and SOD activities increased TBARS and lower GSH; decreased mitofusin and Bcl/Bax expression ratios compared to offspring of normal subjects. These results suggest that the offspring of T2D patients could have an increased metabolic risk of develop a cardiovascular disease mediated by oxidative stress and iron status.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
