Comparison of Real-Time Polymerase Chain Reaction and Enzyme-Linked Immunosorbent Assay for Sensitive and Quantitative Detection of Hazelnuts in Nut Pastes.
Background: Hazelnuts, being a frequent agent of allergenic reactions, need to be detected in food products. Thus, it is necessary to develop and further investigate appropriate methods for detection. Objective: The aim of the study was to compare the analysis of nut pastes (peanut paste spiked with different amounts of hazelnut paste) as a model of contamination of […]
Determination of geographical origin Turkish hazelnuts according to fatty acid composition.
This study focuses on detecting geographical origin of round type hazelnut (Corylus avellena L.) in Turkey using fatty acid (FA) composition. The samples were collected from Western, Central, and Eastern Black Sea regions between 2015 and 2016. FA profiles were determined by gas chromatography (GC), and most abundant fatty acid was oleic acid (C18:1) followed by linoleic acid (C18:2), […]
A Quantitative Risk Assessment of Human Salmonellosis from Consumption of Pistachios in the United States.
We developed a quantitative risk assessment model to assess the risk of human nontyphoidal salmonellosis from consumption of pistachios in the United States and to evaluate the impact of Salmonella treatments (1- to 5-log reductions). The exposure model estimating prevalence and contamination levels of Salmonella at consumption included steps in pistachio processing such as transport […]
Effect of thermal/pressure processing and simulated human digestion on the immunoreactivity of extractable peanut allergens.
Peanut allergy is one of the most widespread types of food allergies especially affecting developed countries. To reduce the risk of triggering allergic reactions, several technological strategies have been devised to modify or remove allergens from foods. Herein we investigated the combination of high temperature and pressure on the modulation of peanuts immunoreactivity after simulated gastro-duodenal digestion. […]
A Quantitative Method for Detecting Ara h 2 by Generation and Utilization of Monoclonal Antibodies.
Peanut (Arachis hypogaea) is one of the most common food allergens that can induce fatal anaphylaxis, and Ara h 2 is one of the major allergen components involved in peanut allergy. The aim of this study was to develop a quantitative method for detecting peanut allergen using monoclonal antibodies against Ara h 2. The splenocytes of […]
Pine nut allergy in Korean children: Clinical characteristics and diagnostic values of specific IgE against pine nuts.
BACKGROUND: Hypersensitivity reactions to pine nuts in children have been occasionally encountered recently, although reports on pine nut allergy cases are rare worldwide. The study aimed to feature clinical and laboratory findings pertaining to pine nut allergy in Korean children. METHODS: Forty-two subjects were enrolled through a retrospective review of medical records, from September 2010 […]
Effects of nut consumption on selected inflammatory markers: a systematic review and meta-analysis of randomized controlled trials.
OBJECTIVE: Several randomized controlled trials (RCTs) have assessed the effects of nut consumption on inflammatory markers. However, the results have been inconsistent. The aim of this meta-analysis of RCTs was to quantitatively evaluate the effects of nut consumption on selected inflammatory markers. METHODS: PubMed, Embase, Cochrane Library database, and Google Scholar were searched for published […]
Walnut phenolic extract inhibits nuclear factor kappaB signaling in intestinal epithelial cells, and ameliorates experimental colitis and colitis-associated colon cancer in mice.
PURPOSE: Walnuts (Juglans regia) are known to have anti-cancer and immunomodulatory effects. However, little information is available on the effects of walnut phenolic extract (WPE) on intestinal inflammation and colitis-associated colon cancer. METHODS: COLO205 cells were pretreated with WPE and then stimulated with tumor necrosis factor (TNF)-α. In the acute colitis model, wild type mice […]
Nuts as a replacement for carbohydrates in the diabetic diet: a reanalysis of a randomised controlled trial.
AIMS/HYPOTHESIS: In line with current advice, we assessed the effect of replacing carbohydrate consumption with mixed nut consumption, as a source of unsaturated fat, on cardiovascular risk factors and HbA1c in type 2 diabetes. The data presented here are from a paper that was retracted at the authors' request ( https://doi.org/10.2337/dc16-rt02 ) owing to lack […]
Walnut Consumption Alters the Gastrointestinal Microbiota, Microbially Derived Secondary Bile Acids, and Health Markers in Healthy Adults: A Randomized Controlled Trial.
Background: Epidemiologic data suggest that diets rich in nuts have beneficial health effects, including reducing total and cause-specific mortality from cancer and heart disease. Although there is accumulating preclinical evidence that walnuts beneficially affect the gastrointestinal microbiota and gut and metabolic health, these relations have not been investigated in humans. Objective: We aimed to assess […]
