Nuts include almonds, Brazil nuts, cashews, hazelnuts, pecans, pistachios, and walnuts. A nut allergy does not necessarily mean that an individual is allergic to other nuts, but certain nuts are closely related, such as cashew nut with pistachio and walnut with nut. Nuts are technically the seeds of certain fruit trees. The nuts you've heard of, such as almonds, walnuts, hazelnuts, pistachios, Brazil nuts, pecans, cashews, etc.
What differentiates them from other fruits that grow on trees, such as apricots and avocados, is that the outermost shell is very hard and the flesh inside is hard or leathery. Almonds, walnuts, hazelnuts, cashews, pine nuts, pistachios, pecans, macadamia nuts and Brazil nuts are tree nuts. A person with a nut allergy may be allergic to one or more of these nuts. Brazil nuts come from the South American tree Bertholletia excelsa, or Brazil nut.
They are a good source of healthy fat, protein, fiber and selenium. Some nuts are closely related to each other, so children with a cashew allergy often have a pistachio allergy, and children with a nut allergy often have a nut allergy (read more about nut families below). Keep learning about nut allergy prevention with more information on when to feed your tender nuts. Nutritionally, Brazil nuts are a rich source (20% or more of the Daily Value, DV) of dietary fiber (30% DV) and various dietary vitamins and minerals.
Brazil nut is known to be pollinated only by large bees with enough strength to lift the hood and enter the flower. The Brazil nut family, Lecythidaceae, belongs to the order Ericales, while the almond belongs to the Rosaceae family, of the order of Rosales. It is a dioecious shrub or tree with evergreen or seasonal leaves up to 24 m tall, which grows in the northern hemisphere in warm or moderate climates. It seems that the main allergen may be a 17.4 kDa protein present in raw and roasted nut extracts.
In a (telephone) survey, of 118 patients who reported peanut or nut allergies, only 2 patients reported allergies to macadamia nuts. Given their impressive nutritional profile, it's no surprise that Brazil nuts have become so popular. Many studies have highlighted high stores of 2S-dependent albumin and other proteins, cross-reactivity between walnuts and pecans, as well as almonds, hazelnuts, Brazil nuts, cashews, pistachios, peanuts and 2S-dependent albumin, and vicillin between walnuts and sesame seeds. These types of allergies usually develop at 2 years of age, and the number of nuts that a person is allergic to may increase with age.
The Ana or 3 reserve protein is associated with the occurrence of severe allergic reactions and is found in large quantities in cashew nuts. In northern Europe, hazelnut allergy is prevalent, while in the United States peanut allergy (and nut allergy, nut allergy). Although beneficial in small quantities, Brazil nuts could cause selenium toxicity if a person regularly ingests them in large quantities. Conformational analysis of linear IgE-binding epitopes mapped to the surface of the Ara h 2 and Ber e 1 molecules showed no structural homology, suggesting that the cross-reactions observed between peanuts and Brazil nuts may depend on other protein panallergens, e.g.
walnuts contain a lot of protein, essential minerals and healthy fats. .
