Accurate prediction of peanut allergy in one-third of adults using a validated Ara h 2 cutoff.

Background: The diagnostic value of peanut components is extensively studied in children, but to a lesser extent in adults with suspected peanut allergy. The use of peanut components in daily practice may reduce the need for double-blind placebo-controlled food challenges (DBPCFCs), however validation studies are currently lacking. Objective: To 1) evaluate the diagnostic value of (combined) peanut […]

Irradiated Tree Nut Flours for Use in Oral Immunotherapy.

Background: Tree nut allergies affect an estimated 1% of the United States population and is lifelong in 90% of allergic individuals. Oral immunotherapy (OIT) for food allergies is an effective method to induce desensitization in a majority of participants in trials of peanut, egg, and milk OIT. Limited trials using tree nut OIT have been reported, […]

The importance of the 2S albumins for allergenicity and cross-reactivity of peanuts, tree nuts and sesame seeds.

Allergies to peanuts, tree nuts, and sesame seeds are among the most important food related causes of anaphylaxis. Important clinical questions include: why is there a variable occurrence of co-allergy among these foods and is this immunologically mediated? Clinical and immunological data summarized here suggest an immunologic basis for these co-allergies based on similarities among […]

Practical challenges and considerations for early introduction of potential food allergens for prevention of food allergy.

Recent randomized controlled trials aimed at the prevention of food allergy have led to sweeping changes in food allergy prevention guidelines. Emphasis is now on the introduction of potential food allergens, particularly peanut and egg, rather than avoidance. Though guidelines recommend against delaying introduction of other potential allergens there remains little or no evidence of […]

Emerging Therapies for Peanut Allergy.

Peanut allergy (PA) is a food allergy that causes an IgE-mediated type I hypersensitivity reaction. PA has become an increasing public health burden, with 2% of American children reported to have this condition in 2010. Current guidelines recommend allergen avoidance, patient education, and administration of H1 antihistamines, β2-agonists, or epinephrine based on the severity of reaction. […]

Peanut Allergy–No Longer a Life Sentence.

In this review we provide an overview on the latest knowledge in the prevention and active management of peanut allergy. The rise in incidence of food allergy has generated new challenges in the management of affected individuals. Strategies to counteract the increase in prevalence of peanut allergy can be considered as a pyramid, beginning with […]

Effect of hot air and infrared roasting on hazelnut allergenicity.

Roasting is known to affect the protein profile and allergenicity of hazelnuts (Corylus avellana cv TGL). The aim of the study was to investigate whether roasting techniques based on different heat transfer methods (hot air and infrared), differently affect the protein solubility and the IgE-binding capacities of both the soluble and insoluble hazelnut protein fractions. […]

Replacing white rice bars with peanuts as snacks in the habitual diet improves metabolic syndrome risk among Chinese adults: a randomized controlled trial.

Background: Observational studies have suggested that intake of nuts is associated with lower risk of cardiometabolic diseases, whereas refined grain consumption has been linked to higher risk. Little is known about whether substituting white rice, a refined grain, with nuts may confer benefit among adults at high risk of cardiometabolic diseases. Objectives: We aimed to evaluate isocaloric […]
