Purpose: To determine the availability and accuracy of information provided by hospitals, imaging centers, and manufacturers regarding gluten in barium sulfate suspensions.
Methods: A total of 105 facilities were contacted via telephone to determine the gluten content of the contrast media used in those facilities. Manufacturers were contacted and their Web sites reviewed to determine the gluten content of their barium products.
Results: Thirty-nine percent of the hospitals and 52% of the imaging centers were not aware of the gluten content of the contrast media they used. Twenty-nine-and-a-half percent of the respondents provided the correct gluten content. The manufacturers noted that 5 products were tested and confirmed gluten free, 1 product was not tested but described as gluten free, 1 product's gluten content depended upon its flavor, and 1 product was reported to contain gluten.
Discussion: Clinicians caring for patients with celiac disease or patients who choose to restrict their gluten consumption must ensure that the barium sulfate suspension ingested is gluten free.
Conclusion: It can be difficult to determine the gluten content of barium sulfate, as a majority of radiology departments and imaging centers did not know whether the product they use is gluten free. Educating staff members and improving product labeling would benefit the quality of care provided to patients with celiac disease.

Background And Aims: Chemotherapy is one of the treatments of choice for patients with hematological or head and neck neoplasms. However, chemotherapy promotes elevate occurrence of adverse events and many of them directly impact nutritional status and patients' quality of life, which may include a low treatment tolerance. Suggested mechanisms include inflammation and oxidative stress as contributing factors to adverse effects of chemotherapy.

Whole grain flour is considered a part of a healthy diet, especially when produced with pigmented wheat (). However, the specific metabolic pathways and mechanisms by which these metabolites affect the end-use quality of pigmented wheat varieties still need to be better understood. This study examined the relationship between metabolite concentrations and the end-use quality of three wheat varieties: common wheat (CW, JM20), black wheat (BW, HJ1), and green wheat (GW, HZ148).

Department of Food Science and Biotechnology, Institute of Life Science and Resources, Graduate School of Biotechnology, Kyung Hee University, Yongin 17104, Republic of Korea.
Short-chain glucan aggregates (SCGA), a type of resistant starch (RS) Ⅲ, is produced by debranching amylopectin with pullulanase and inducing self-assembly. Despite its low digestibility and high RS content, SCGA has not been applied to real food systems, especially noodles. The objective of this study was to determine the feasibility of low-digestible noodles using SCGA and to evaluate their quality characteristics and in vitro digestibility of starch gel.

The present study aimed to investigate the effects of banana flours obtained from different banana cultivars (Grand Nain (GN), Azman (AZ), and Erdemli (ER)) on some basic physicochemical, bioactive, textural, and sensory properties of the gluten-free cookie samples by the simplex lattice mixture design approach. Incorporating banana powder into cookie samples resulted in significant changes in the parameters studied. The banana flours' total dietary fiber and total starch levels ranged between 1.

Effects of catechins with different structure characteristics on the structure and properties of gluten-catechin covalent complex were investigated, and the structure-activity relationship was further explored. Catechins including epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and epigallocatechin-3-gallate (EGCG) could successfully covalently bind with gluten through C-N and/or C-S bonds. The physicochemical properties of covalent complex, including particle size, thermal stability, content of free amino groups, free sulfhydryl groups and disulfide bonds, were significantly affected by different catechins, and the action order was: EGCG > ECG > EGC > EC.
