Preventing peanut allergy: where are we now?
Peanut allergy affects 1% to 3% of the Western world, usually begins in early childhood, is rarely outgrown, and has no currently approved treatment. The identification and application of prevention strategies is therefore essential. In 2015, the Learning Early About Peanuts study findings found that early consumption of peanut protein was effective in preventing peanut allergy in […]
Sensitivity, specificity, and predictive value of oral mucosal brush biopsy for the diagnosis of peanut allergy.
BACKGROUND: Current diagnostic testing methods for peanut allergy, including serum specific immunoglobulin E (sIgE) and skin-prick testing (SPT), have low specificity, whereas oral food challenge (OFC) carries significant risk of provoking adverse events. Mucosal brush biopsy (MBB) from the oral cavity is currently being studied as a new diagnostic test for peanut allergy, but normative […]
Health benefits of nut consumption.
Nuts (tree nuts and peanuts) are nutrient dense foods with complex matrices rich in unsaturated fatty and other bioactive compounds: high-quality vegetable protein, fiber, minerals, tocopherols, phytosterols, and phenolic compounds. By virtue of their unique composition, nuts are likely to beneficially impact health outcomes. Epidemiologic studies have associated nut consumption with a reduced incidence of […]
Peanut Allergy in Spanish Children: Comparative Profile of Peanut Allergy versus Tolerance.
BACKGROUND: Peanut storage proteins (Ara h 1, Ara h 2, and Ara h 3) have been described as the major peanut allergens in children, although not all peanut-sensitized individuals have clinical reactivity after exposure. OBJECTIVES: We studied the sensitization profile of peanut-allergic and peanut-tolerant children in a pediatric cohort. METHODS: The clinical features and sensitization […]
Nut sensitization profile in Southern Taiwan.
BACKGROUND/PURPOSE: To evaluate the relationship between serum-specific immunoglobulin E (IgE) to peanuts/tree nuts and their clinical manifestations in atopic diseases. METHOD: Serum from people with the classical symptoms of asthma, allergic rhinitis (AR), or atopic dermatitis (AD) was collected for the measurement of serum-specific IgE to peanuts, cashew nuts, Brazil nuts, almonds, and coconuts. Cases […]
The functional biology of peanut allergens and possible links to their allergenicity
Peanut is one of the most common food triggers of fatal anaphylaxis worldwide although peanut allergy affects only 1-2% of the general population. Peanuts are the source of highly potent allergenic proteins. It is emerging that the allergenicity of certain proteins is linked to their biological function. Peanut is an unusual crop in that it flowers above […]
Nut and peanut butter consumption and the risk of lung cancer and its subtypes: A prospective cohort study.
OBJECTIVES: Nut consumption has been associated with reduced cancer-related mortality, but evidence for a relation between nut intake and lung cancer risk is limited. We investigated the association between total nut, tree nut, peanut, and peanut butter intake and the risk of lung cancer and its subtypes in the Netherlands Cohort Study. MATERIALS AND METHODS: […]
The Effects of Nut Consumption on Vascular Function.
Vascular stiffness can be measured using numerous techniques including assessments of central haemodynamics, aortic arterial stiffness, and indices of aortic wave reflection and endothelial dilatation. Impaired vascular function is associated with increased risk of cardiovascular disease (CVD). Epidemiological studies indicate that regular nut consumption reduces CVD risk, with one of the proposed mechanisms being via […]
The Effect of Microwave Pretreatment on Micronutrient Contents, Oxidative Stability and Flavor Quality of Peanut Oil.
The purpose of the present study is to investigate the changes in extraction yield, physicochemical properties, micronutrients content, oxidative stability and flavor quality of cold pressed peanut oil extracted from microwave (MW) treated seeds (0, 1, 2, 3, 4, 5 min, 700 W). The acid value and peroxide value of extracted oil from MW-treated peanuts were slightly […]
A comprehensive review of the value-added uses of peanut (Arachis hypogaea) skins and by-products.
Globally, peanut seeds are grown for oil production, peanut butter, confections, snacks and protein extenders, leaving the peanut by-products (skins, peanut hulls) as waste for disposal. Numerous studies have identified the value added attributes of peanut skins and/or peanut skin extracts as an antioxidant, functional food ingredient, animal production feed ingredient, and antimicrobial agent. This […]
