Removal of methylene blue dye from aqueous solutions by adsorption on levulinic acid-modified natural shells.
This study has developed an innovative and environmentally friendly approach for the removal of methylene blue (MB) dye by natural shells (NShs) chemically modified with levulinic acid (LA). Almond shell (ASh), walnut shell (WSh), and apricot kernel shell (AKSh) were used as waste fillers. The adsorption behavior of MB onto the biosorbents was investigated with […]
Updated population minimal eliciting dose distributions for use in risk assessment of 14 priority food allergens.
Food allergy and allergen management are important global public health issues. In 2011, the first iteration of our allergen threshold database (ATDB) was established based on individual NOAELs and LOAELs from oral food challenge in roughly 1750 allergic individuals. Population minimal eliciting dose (EDp) distributions based on this dataset were published for 11 allergenic foods […]
Tree Nuts Anaphylaxis in Preschool Age Children.
Introduction. The incidence of food-induced anaphylaxis (FIA) is increasing in young children. Although the commonest culprits are cow's milk and egg, FIA to tree nuts (TNs) have been increasing. Objective. Characterization of children referred to our allergy department due to TNs-induced anaphylaxis (TNs-FIA) during preschool age. Materials and methods. We have retrospectively included 25 children […]
Hydroethanolic extract of Juglans regia L. green husks: A source of bioactive phytochemicals.
Juglans regia L. (walnut) green husks are an important fraction of waste resulting from the walnut production, thus representing an interesting natural matrix to explore as a source of bioactive compounds. In this work, the hydroethanolic extract of walnut green husks was studied considering the phytochemical composition and the biological activity using different cell model […]
Beneficial Effects of Walnuts on Cognition and Brain Health.
Oxidative stress and neuroinflammation have important roles in the aging process, mild cognitive impairment (MCI), Alzheimer's disease (AD), and other brain disorders. Amyloid beta protein (Aβ) is the main component of amyloid plaques in the brains of people with AD. Several studies suggest that Aβ increases the generation of free radicals in neurons, which leads […]
Effects of Supplementing the Usual Diet with a Daily Dose of Walnuts for Two Years on Metabolic Syndrome and Its Components in an Elderly Cohort.
Accumulating evidence links nut consumption with an improved risk of metabolic syndrome (MetS); however, long-term trials are lacking. We examined the effects of a daily dose of walnuts for two years on MetS in a large elderly cohort. A total of 698 healthy elderly participants were randomly assigned to either a walnut supplemented or a […]
The Effect of Walnut Consumption on n-3 Fatty Acid Profile of Healthy People Living in a Non-Mediterranean West Balkan Country, a Small Scale Randomized Study.
People living in non-Mediterranean West Balkan countries have diets with a low n-3 polyunsaturated fatty acid (PUFA) content. Walnuts, a traditional Serbian food, could be an excellent source of n-3 PUFA. The first sub-study evaluated the fatty acid and mineral content of Serbian walnuts, demonstrating that walnuts had the high content of linolenic acid (C18:3, […]
Effect of a 2-year diet intervention with walnuts on cognitive decline. The Walnuts And Healthy Aging (WAHA) study: a randomized controlled trial.
Background: Walnut consumption counteracts oxidative stress and inflammation, 2 drivers of cognitive decline. Clinical data concerning effects on cognition are lacking. Objectives: The Walnuts And Healthy Aging study is a 2-center (Barcelona, Spain; Loma Linda, CA) randomized controlled trial examining the cognitive effects of a 2-y walnut intervention in cognitively healthy elders. Methods: We randomly […]
DNA barcoding coupled with high‐resolution melting analysis for nut species and walnut milk beverage authentication.
Background: Walnut (Juglans regia L.) is one of the most widely cultivated nuts. Walnut milk beverage is very popular in China due to its nutritional value. However, adulterated walnut milk ingredients have been detected in the Chinese market. Peanut and soybean are sold at much lower prices than walnut and are reported as common adulterated species […]
Determination of Trace and Major Elements in Vegan Milk and Oils by ICP-OES After Microwave Digestion
Increasing technological developments also bring about environmental pollution. Heavy metals and metallic compounds, as a result of soil, water, and air industrialization, pass through to people and animals through the food chain and have a negative impact on health. In this study, the concentrations of Na, Mg, K, Ca, P, Fe, Cu, B, Mn, Zn, […]
