碳水化合物是食物的主要成分之一,也是人类膳食的主要能量来源,通常包括糖类、淀粉和纤维。在这三大来源中,淀粉是储量最丰富的碳水化合物之一。研究淀粉不仅可以加深人们对淀粉在人体中的功能的理解,而且有助于开发设计新的淀粉基膳食食品。本文首先综述了国内外对快消化淀粉(RDS)、慢消化淀粉(SDS)和抗性淀粉(RS)等的最新研究进展,然后介绍了淀粉基膳食食品消化率的体内和体外测定方法。在此基础上,提出了通过直接添加变性淀粉或改变加工条件来设计新型淀粉基膳食食品的研究策略。最后,本文对淀粉类食品未来的研究方向进行了展望。

Interest in understanding the digestion behavior of starch in the presence of dietary fibers is growing due to the ability of dietary component to control the release and absorption of glucose. This presents an outstanding opportunity to improve the quality of food products by incorporating dietary fiber into starchy food products. The physicochemical properties of different fibers and their behavior in the gastrointestinal tract (GIT) differ. To test the efficacy of these different fibers on starch digestion, static in vitro digestion models under conditions that mimic the human GIT are frequently used. Indeed, many efforts have been committed to the development of various static in vitro protocols for starch digestion. Though not considered as the gold standard in digestibility studies in food science and technology, static simulated models provide a useful alternative to in vivo techniques for rapid screening of the digestibility of food products under conditions that simulate the human GIT. This review presents the current status and development of digestion techniques for simulating digestion conditions in the human GIT, with particular interest on starch digestion in the presence of dietary fiber in the three phases of digestions including the oral, gastric and the intestinal steps. This summary can benefit investigators in developing static in vitro digestion models designed to simulate starch digestion with relevant values of the quantifiable parameters, including pH, enzymes and simulated digestive fluids.

This study compared proteome profiles and morphological changes of rat jejunum in response to different dietary proteins. Fifty male Sprague-Dawley rats were fed with casein (control), and isolated beef, pork, fish and chicken proteins for 14 days. Proteome analysis, histological observation and PEPT1 quantification of the jejunum were performed. The results indicated that rats fed with chicken proteins had higher PEPT1 mRNA and protein levels (P<0.05) but lower villus height and ratio of villus height to crypt depth (V/C ratio, P<0.05) than those fed with casein and pork protein. Label-free LC-MS/MS indicated that, as compared to casein, intake of chicken protein can regulate oligopeptide transport mainly by upregulating PEPT1 protein expression and reducing dipeptidyl-peptidase activity related to biological oxidation, and can reduce oligopeptide absorption capacity by regulating Hippo signaling pathway. Although intake of beef and fish proteins had no significant effect on PEPT1 expression, they altered several signaling pathways.

As muscle activity during growth is considerably important for mandible quality and morphology, reducing dietary loading directly influences the development and metabolic activity of mandibular condylar cartilage (MCC). However, an overall investigation of changes in the protein composition of MCC has not been fully described in literature. To study the protein expression and putative signaling in vivo, we evaluated the structural changes of MCC and differentially expressed proteins induced by reducing functional loading in rat MCC at developmental stages. Isobaric tag for relative and absolute quantitation-based 2D nano-high performance liquid chromatography (HPLC) and matrix-assisted laser desorption/ionization time-of-flight/ time-of-flight (MALDI-TOF/TOF) technologies were used. Global protein profiling, KEGG and PANTHER pathways, and functional categories were analyzed. Consequently, histological and tartrate-resistant acid phosphatase staining indicated the altered histological structure of condylar cartilage and increased bone remodeling activity in hard-diet group. A total of 805 differentially expressed proteins were then identified. GO analysis revealed a significant number of proteins involved in the metabolic process, cellular process, biological regulation, localization, developmental process, and response to stimulus. KEGG pathway analysis also suggested that these proteins participated in various signaling pathways, including calcium signaling pathway, gap junction, ErbB signaling pathway, and mitogen-activated protein kinase signaling pathway. Collagen types I and II were further validated by immunohistochemical staining and Western blot analysis. Taken together, the present study provides an insight into the molecular mechanism of regulating condylar growth and remodeling induced by reducing dietary loading at the protein level.

This study aimed to explore the association of maternal depression with nutrient intake, growth, and development of preterm infants. A cohort study of 201 infants was conducted in Beijing. Based on the gestational age of an infant and status of the mother, the infants were divided into four groups: non-depression-fullterm (64), non-depression-preterm (70), depression-fullterm (36), and depression-preterm (31). Data on sociodemographic characteristics, nutritional intake, growth, and developmental status of children at 8 months (corrected ages) were collected using a quantitative questionnaire, a 24-Hour Dietary Recall, anthropometric measurements, and the Bayley-III scale. A multivariate analysis was used to evaluate the effects of maternal depression and preterm birth on infant growth and development. The energy, protein, and carbohydrate intake in the depression group was lower than the recommended amounts. The depression preterm groups indicated the lowest Z-scores for length and weight and the lowest Bayley-III scores. Preterm infants of depressed mothers are at high risks of poor growth and development delay.
