Development of PCR, LAMP and qPCR Assays for the Detection of Aflatoxigenic Strains of Aspergillus flavus and A. parasiticus in Hazelnut.
Aspergillus flavus and A. parasiticus are two species able to produce aflatoxins in foodstuffs, and in particular in hazelnuts, at harvest and during postharvest phase. As not all the strains of these species are aflatoxin producers, it is necessary to develop techniques that can detect aflatoxigenic from not aflatoxigenic strains. Two assays, a LAMP (loop-mediated isothermal amplification) and […]
In Vitro Protein Digestibility and Fatty Acid Profile of Commercial Plant-Based Milk Alternatives.
Plant-based milk alternatives (PBMA) are a new popular food trend among consumers in Europe and North America. The forecast shows that PBMA will double their value by 2023. The objective of this study was to analyze the nutritional value of commercial products in terms of their fatty acid profile and protein digestibility from commercial PBMA. […]
Reduced peanut sensitization with maternal peanut consumption and early peanut introduction while breastfeeding.
New guidelines for peanut allergy prevention in high-risk infants recommend introducing peanut during infancy but do not address breastfeeding or maternal peanut consumption. We assessed the independent and combined association of these factors with peanut sensitization in the general population CHILD birth cohort (N = 2759 mother-child dyads). Mothers reported peanut consumption during pregnancy, timing […]
IgE-binding to vicilin-like antimicrobial peptides is associated with systemic reactions to macadamia nut.
Background: Macadamia nut can induce fatal allergic reactions and changes in dietary habits will raise their consumption in industrialised countries. Until now diagnosis of macadamia nut allergy by sIgE solely relies on the macadamia nut extract, but single components are lacking. Methods: Macadamia nut proteins recognised by IgE from 2 macadamia nut extract positive sera were identified […]
Usefulness of r Ana o 3 assessment before oral food challenge to pistachio.
Cashew and pistachio both belong to the Anarcardiacae family. Cashew and pistachio allergies may cause severe symptoms such as anaphylaxis with a very low eliciting dose1,2 . The cashew 2S albumin r Ana o 3 is the only singleplex component-resolved diagnosis immunoassay currently available in clinical practice3-5 . Its structural similarity with the pistachio 2S albumin may […]
Food and food products associated with food allergy and food intolerance-An overview.
Immune-mediated food allergy and non-immune mediated food intolerance are categorized as the most common adverse reactions resulting from the ingestion of certain foods. As there is no standard treatment, the possible remedy to avoid exposure to these adverse reactions is adhering to a strict diet that eliminates allergic and intolerant foods. The commonly consumed foods […]
Basophil activation test shows high accuracy in the diagnosis of peanut and tree nut allergy: The Markers of Nut Allergy Study.
Background: Peanut and tree nut allergies are the most important causes of anaphylaxis. Co-reactivity to more than one nut is frequent, and co-sensitization in the absence of clinical data is often obtained. Confirmatory oral food challenges (OFCs) are inconsistently performed. Objective: To investigate the utility of the basophil activation test (BAT) in diagnosing peanut and tree nut […]
Walnut-Enriched Diet Elevated α-Linolenic Acid, Phytoprostanes, and Phytofurans in Rat Liver and Heart Tissues and Modulated Anti-inflammatory Lipid Mediators in the Liver.
α-Linolenic acid (ALA) and its non-enzymatic oxidized products, namely, phytoprostanes and phytofurans, are found in some nuts. The uptake and deposition of these compounds are not well-defined. Walnut has high ALA and a considerable amount of phytoprostanes and phytofurans compared to other common nuts. When fed to rodents, ALA and eicosapentaenoic acid levels increased in […]
A Walnut Diet in Combination with Enriched Environment Improves Cognitive Function and Affects Lipid Metabolites in Brain and Liver of Aged NMRI Mice.
This in vivo study aimed to test if a diet enriched with 6% walnuts alone or in combination with physical activity supports healthy ageing by changing the oxylipin profile in brain and liver, improving motor function, cognition, and cerebral mitochondrial function. Female NMRI mice were fed a 6% walnut diet starting at an age of […]
Nut Consumption for Cognitive Performance: A Systematic Review.
Diet is considered an important modifiable lifestyle factor capable of attenuating early cognitive changes in healthy older people. The inclusion of nuts in the diet has been investigated as a dietary strategy for maintenance of brain health across the lifespan. This review aimed to present up-to-date evidence regarding the association between nut intake and cognitive […]
