Association of nut consumption with insulin resistance and blood lipid profile in Spanish university students
Aims: To examine whether nut consumption was associated with insulin resistance and blood lipid parameters in a sample of young healthy adults. Material and methods: A cross-sectional study was conducted involving 306 first-year students (aged 18-30 years) from the University of Castilla-La Mancha, Spain. Biochemical variables related to insulin resistance and blood lipid profile (glucose, […]
Effect of a Mediterranean Diet or Mindfulness-Based Stress Reduction During Pregnancy on Child Neurodevelopment: A Prespecified Analysis of the IMPACT BCN Randomized Clinical Trial
Importance: Maternal suboptimal nutrition and high stress levels are associated with adverse fetal and childhood neurodevelopment. Objective: To test the hypothesis that structured interventions based on a Mediterranean diet or mindfulness-based stress reduction (MBSR) during pregnancy improve child neurodevelopment at age 2 years. Design, Setting, and Participants: This was a prespecified analysis of the parallel-group […]
Natural variation in photosynthesis and water use efficiency of locally adapted Persian walnut populations under drought stress and recovery
Persian walnut is a drought-sensitive species with considerable genetic variation in the photosynthesis and water use efficiency of its populations, which is largely unexplored. Here, we aimed to elucidate changes in the efficiency of photosynthesis and water content using a diverse panel of 60 walnut families which were submitted to a progressive drought for 24 […]
Dietary Fibers of Tree Nuts Differ in Composition and Distinctly Impact the Fecal Microbiota and Metabolic Outcomes In Vitro
This study aimed to evaluate and compare the effects of dietary fibers (DFs) of commercially important tree nuts (almond, cashew, hazelnut, pistachio, and walnut) on gut microbiota in vitro. Microbial compositions and short-chain fatty acids were determined using 16S rRNA sequencing and gas chromatography (GC), respectively. Neutral and acidic monosaccharides were analyzed using GC/MS and […]
Antioxidant and Anti-Inflammatory Properties of Walnut Constituents: Focus on Personalized Cancer Prevention and the Microbiome
Walnuts have been lauded as a ‘superfood’, containing a remarkable array of natural constituents that may have additive and/or synergistic properties that contribute to reduced cancer risk. Walnuts are a rich source of polyunsaturated fatty acids (PUFAs: alpha-linolenic acid, ALA), tocopherols, antioxidant polyphenols (including ellagitannins), and prebiotics, including fiber (2 g/oz). There is a growing […]
The potential of almonds, hazelnuts, and walnuts SFE-CO2 extracts as sources of bread flavouring ingredients
Nuts have been part of the human diet since our early ancestors, and their use goes beyond nutritional purposes, for example, as aromatic sources for dairy products. This work explores the potential of almond (Prunus dulcis (Mill.) DA Webb), hazelnut (Corylus avellana L.), and walnut (Juglans regia L.) extracts as sources of food flavouring agents, […]
Leaf spot disease on Juglans regia caused by Ragnhildiana diffusa in China
Juglans regia L. is commercially important for its edible nuts, which is a major species of walnut trees in Sichuan Province (Luo et al. 2020). In September 2021, brown leaf spot symptoms were observed on roughly 75% of 60 J. regia trees surveyed in an orchard of Chongzhou city (30°40’6”N, 103°40’18”E). Initially, the lesions measuring […]
Trunk rot of Juglans regia caused by Myrmaecium fulvopruinatum in China
Walnut (Juglans regia) is a deciduous tree of the Juglandaceae family, widely cultivated in China, and provides value in a variety of ways, including the usage of the wood and nuts, and offers substantial economic, social, and environmental advantages (Wang et al, 2017). Nevertheless, a fungal disease of causing walnut trunk rot was observed in […]
Effect of walnut consumption on neuropsychological development in healthy adolescents: a multi-school randomised controlled trial.
Background: Omega-3 fatty acids are critical for neuropsychological functioning. Adolescence is increasingly believed to entail brain vulnerability to dietary intake. The potential benefit on adolescent neurodevelopment of consuming walnuts, a source of omega-3 alpha-linolenic acid (ALA), remains unclear. Methods: We conducted a 6-month multi-school-based randomized controlled nutrition intervention trial to assess whether walnut consumption has […]
Alternaria alternata Causing Brown Spot Disease on Walnut in Xinjiang, China.
Walnut is one of the Xinjiang’s characteristic dried fruits and the main source of income for farmers in walnut growing areas. In September 2019, Juglans regia leaves with brown spots were observed in a 10 hm2 orchard in Hotan area, the diseased leaf rate reached more than 25%. The leaf lesions were suborbicular to irregular, […]
