Does Walnut Supplementation Have Favourable Effect Apolipoprotein A, B and Blood Pressure? A Systematic Review
Backgrounds: Many randomised controlled trials (RCTs) have revealed the benefits of walnut on apolipoproteins and blood pressure, but the results are inconclusive. This meta-analysis of RCTs aimed to assess the effects of walnut on Apolipoprotein B (ApoB), apolipoprotein A1 (ApoA1) and blood pressure. Methods: A systematic review of PubMed, Scopus, Web of Science, Cochrane and […]
Effects of Walnut Consumption on Blood Lipid Profile and Apolipoproteins in Adults: A GRADE-Assessed Systematic Review and Dose-Response Meta-Analysis of 49 Randomized Controlled Trials
Walnuts (Juglans regia L.) are rich in polyunsaturated fatty acids (PUFAs), fiber, and bioactive compounds that may positively affect lipid metabolism. Although several clinical trials have examined their impact on the lipid profile, results have been inconsistent, and evidence regarding their effects on apolipoproteins is limited. This meta-analysis aims to systematically assess the impact of […]
Compositional Characteristics, Texture, Shelf‐Life and Sensory Quality of Sweet Walnut Pastes
Walnut pastes represent a promising functional food product due to the nutritional value of walnuts (Juglans regia L.). However, little is known about the impact of formulation and processing on their stability during storage. This study aimed to assess the effect of formulation and processing variables conditions for walnut paste production and to evaluate the […]
Physically crosslinked polyphenol-chitosan edible coating for the application of walnut kernels during roasting
This study developed an edible chitosan-based coating incorporating the main polyphenols from walnut kernel seed coats (gallic acid, ferulic acid, and ellagic acid) to enhance the oxidative stability and sensory quality of fresh walnut kernels during roasting. SEM and AFM analysis revealed that gallic acid-loaded chitosan films exhibited a uniform yet rough morphology, while zeta […]
Fermentation as a strategy to improve the bioactive and antioxidant properties of walnuts and their derived products
Oxidative stress is a significant factor in the development of many chronic illnesses, and antioxidants play a vital role in mitigating its effects. The walnut (Juglans regia L.) is widely recognized for its diverse range of bioactive compounds, particularly polyphenols, flavonoids, and tocopherols, which exhibit notable antioxidant properties. These beneficial compounds are found in various […]
Trends over a decade in the prevalence and eliciting dose of peanut and tree nut allergies in Japan
Background: The prevalence of tree nuts allergy is rapidly increasing in Japan, yet the eliciting dose (ED) for tree nuts, particularly in Asian populations, has not been sufficiently investigated. Objective: This study aimed to quantify EDs for peanut, cashew nut, and walnut in Japanese patients with food allergies and to investigate longitudinal changes in these […]
Daily walnut consumption increases 6-sulfatoxymelatonin urinary levels and can improve sleep quality: a randomized crossover trial
We aimed to study the potential impact of daily consumption of walnuts on urinary 6-sulphatoxymelatonin (6-SMT) levels and sleep quality parameters. We conducted an open-label randomized crossover trial (NCT04799821) in 76 young adults (24.1 ± 3.4 years; 85.5% women) who either ingested 40 g of walnuts daily during dinner (intervention) or refrained from eating walnuts […]
