Development of a Drinkable, Peanut-Based Dietary Supplement and Comparison of Its Nutritional and Microbiological Qualities with Commercial Products.
This study was undertaken to formulate, using peanuts as a major ingredient, a beverage which will benefit older adults who are at a high risk of protein-energy malnutrition and other health complications, and to compare its nutritional and microbiological qualities to commercial products. Peanuts, rice flour, and flaxseed meal in a ratio of 48.0:49.8:2.2 were […]
Peanut allergy in Mexican children: what is the effect of age at first consumption?
Studies suggest that children who start solid foods early are at risk for developing food allergies. Herein, we evaluated the effects of the introduction of peanuts to the diets of children on emerging peanut allergies. Children with allergic rhinitis and asthma were enrolled in the present study and evaluated in four stages. In the first […]
Effect of Avoidance on Peanut Allergy after Early Peanut Consumption.
Background In a randomized trial, the early introduction of peanuts in infants at high risk for allergy was shown to prevent peanut allergy. In this follow-up study, we investigated whether the rate of peanut allergy remained low after 12 months of peanut avoidance among participants who had consumed peanuts during the primary trial (peanut-consumption group), […]
Dietary Protein Intake and Risk of Type 2 Diabetes in US Men and Women.
Dietary proteins are important modulators of glucose metabolism. However, few longitudinal studies have evaluated the associations between intake of protein and protein type and risk of type 2 diabetes (T2D). We investigated the associations between total, animal, and vegetable protein and incident T2D in 72,992 women from the Nurses' Health Study (1984-2008), 92,088 women from […]
The component-specific to total IgE ratios do not improve peanut and hazelnut allergy diagnoses.
BACKGROUND: Specific IgE measurement predicts the outcome of oral food challenges with considerable uncertainty when evaluating food allergy. OBJECTIVE: Our aim was to assess whether accounting for the ratio of component- or allergen-specific to total IgE can improve this prediction. METHODS: This multicenter study collected blood samples from children with suspected peanut or hazelnut allergy […]
Prospective investigation on the transfer of Ara h 2, the most potent peanut allergen, in human breast milk.
BACKGROUND: Peanut allergy is one of the most severe food allergies. Whether breast feeding induces tolerance to peanuts or on the contrary, predisposes at risk-babies to occult allergic sensitization to peanuts is still a matter of discussion. We sought to investigate the transfer of the most potent peanut allergen Ara h 2 into human breast […]
The genome sequences of Arachis duranensis and Arachis ipaensis, the diploid ancestors of cultivated peanut.
Cultivated peanut (Arachis hypogaea) is an allotetraploid with closely related subgenomes of a total size of ∼2.7 Gb. This makes the assembly of chromosomal pseudomolecules very challenging. As a foundation to understanding the genome of cultivated peanut, we report the genome sequences of its diploid ancestors (Arachis duranensis and Arachis ipaensis). We show that these […]
Bioavailability assessment of essential and toxic metals in edible nuts and seeds.
Bioavailability of essential and toxic metals in edible nuts and seeds has been assessed by using an in vitro dialyzability approach. The samples studied included walnuts, Brazil nuts, Macadamia nuts, pecans, hazelnuts, chestnuts, cashews, peanuts, pistachios and seeds (almond, pine, pumpkin and sunflower). Metals were measured by inductively coupled plasma-mass spectrometry in dialyzates and also […]
Is Microarray Analysis Really Useful and Sufficient to Diagnose Nut Allergy in the Mediterranean Area?
BACKGROUND: Component-based diagnosis on multiplex platforms is widely used in food allergy but its clinical performance has not been evaluated in nut allergy. OBJECTIVE: To assess the diagnostic performance of a commercial protein microarray in the determination of specific IgE (sIgE) in peanut, hazelnut, and walnut allergy. METHODS: sIgE was measured in 36 peanut-allergic, 36 […]
Prevalence of Peanut, Tree Nut, Sesame, and Seafood Allergy in Mexican Adults.
OBJECTIVE: To identify the prevalence of perceived and probable allergic reactions to peanuts, tree nuts, sesame seed, or seafood and its association with the personal history of allergic disease. METHODS: A cross-sectional study was performed in four cities of the metropolitan area of Guadalajara, located in western Mexico. Through sampling by gender and age, 1,126 […]
