Widespread Supplement Intake and Use of Poor Quality Information in Elite Adolescent Swiss Athletes
In conclusion, this study among elite adolescent Swiss athletes indicates a widespread and large-scale use of dietary supplements, which was associated with a low level of information quality.PMID:34552032 | DOI:10.1123/ijsnem.2021-0043 (Source: International Journal of Sport Nutrition and Exercise Metabolism)

Skimmed breast milk for treatment of hypertriglyceridemia in an infant with congenital nephrotic syndrome
We describe successful treatment of severe hypertriglyceridemia through dietary changes in a boy with CNS. A 9-day-old boy presented to the emergency department with lower extremity edema caused by deep venous thrombosis. Laboratory evaluation identified hypoalbuminemia, nephrotic-range proteinuria, and a pathogenic variant of the NPHS1 gene. The initial triglyceride concentration of 369 mg/dl increased to 3096 mg/dl by 5 weeks of age, when his diet consisted of breast milk. Refrigerated breast milk was skimmed by removing the top layer after allowing it to separate for 24 h. This process was repeated prior to use. Skimmed...

Analysis of per- and poly-fluoroalkyl substances (PFAS) in processed foods from FDA's Total Diet Study
Anal Bioanal Chem. 2021 Aug 26. doi: 10.1007/s00216-021-03610-2. Online ahead of print.ABSTRACTAdditional occurrence data are needed to better understand human exposure to per- and poly-fluoroalkyl substances (PFAS) from commercially available foods in the United States. The Food and Drug Administration's (FDA) Total Diet Study (TDS) collects foods that are both nationally and regionally distributed. In 2018, 172 processed foods were collected from grocery stores around Lenexa, KS, as part of the TDS national collection. A previously developed method for the analysis of PFAS in foods as part of the TDS regional collection ...

A 16-week randomized controlled trial of a fish oil and whey protein-derived supplement to improve physical performance in older adults losing autonomy —A pilot study
ConclusionBecause of low eligibility, the pilot study was interrupted and deemed non-feasible; adherence to rigorous study assessments and to supplements was adequate except for long-term fish oil. The non-amended protocol may be applied to populations with greater functional capacity. Trial registrationClinicalTrials.gov NCT04454359. (Source: PLoS One)

Molecules, Vol. 26, Pages 4347: Development, Validation and Application of an ICP-SFMS Method for the Determination of Metals in Protein Powder Samples, Sourced in Ireland, with Risk Assessment for Irish Consumers
e Furey A method has been developed, optimised and validated to analyse protein powder supplements on an inductively coupled plasma-sector field mass spectrometer (ICP-SFMS), with reference to ICH Guideline Q2 Validation of Analytical Procedures: Text and Methodology. This method was used in the assessment of twenty-one (n = 21) elements (Al, Au, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Mn, Mo, Pb, Pt, Sn, Ti, Tl, V) to evaluate the safety of thirty-six (n = 36) protein powder samples that were commercially available in the Irish marketplace in 2016/2017. Using the determined concentrations of elements in samples (�...

Molecules, Vol. 26, Pages 3781: Novel Spray Dried Algae-Rosemary Particles Attenuate Pollution-Induced Skin Damage
Mary Ann Lila The present study investigated the effect of spray-dried algae-rosemary particles against pollution-induced damage using ex-vivo human biopsies exposed to diesel engine exhaust (DEE). For this, the complexation of hydroalcoholic rosemary extract with Chlorella (RCH) and Spirulina (RSP) protein powders was conducted. The process efficiency and concentration of rosmarinic acid (RA), carnosic acid (CA), and carnosol (CR) phenolic compounds of both products were compared. The RSP spray-dried production was more efficient, and RSP particles presented higher CR and CA and similar RA concentrations. Therefore, s...

Preparation of high concentration protein powder suspensions by milling of lyophilizates
In this study protein powder suspensions were prepared using a swing-mill. Milling of lyophilizates containing a model monoclonal antibody in presence of the suspension vehicle was compared to cryogenic dry milling. Wet media milling led to injectable suspensions, but resulted in monomer loss and increase in protein aggregation. When the lyophilizates were cryogenic dry ball milled less aggregation and monomer loss were detected. Differences related to protein integrity were found for different process parameters, which were successfully optimized. If not cooled with liquid nitrogen, dry milling resulted in increased damag...

Fraud in nutritional supplements for athletes: a narrative review
Nutr Hosp. 2021 May 10. doi: 10.20960/nh.03413. Online ahead of print.ABSTRACTThe use of nutritional supplements (NSs) is a widespread practice in both professional and amateur athletes. Their choice must be based on criteria of safety, legality, and effectiveness. There are several risks that some of these products can trigger, this being a reason for fraud to the consumer. By way of example, the presence of a legal substance in doses higher than its recommendation may cause unwanted side effects; on the other hand, its presence in quantities lower than necessary (effective threshold) may not have the effect expected or a...
