What is a cashew allergy

The cashew is technically not a nut; it is a seed harvested from the cashew apple, the fruit produced by cashew trees.

Unlike numerous other nuts and seeds, the cashew grows exterior the fruit instead of inside, within a kidney-shaped drupe that hangs at the finish of the cashew apple’s base.

This drupe is considered the ‘true’ fruit of the tree while the cashew apple is thought of as an accessory or ‘false’ fruit.

Contained within this ‘true’ fruit is a single seed—the cashew.

It is worthwhile adding that, while cashews are certainly the most renowned product of the cashew tree, the cashew apple is a delicacy in numerous countries, including my home country Brazil, and is used to make juices, jams, curries and an Indian liqueur called feni.


Where Do Cashews Come From?

Cashews are called caju in Brazil, maranon in some Spanish-speaking locations, and merey in Venezuela.

The original expression is acaju (meaning the ‘nut that produces itself’), which comes from the language of the Tupian people who live in northeast Brazil where cashew trees originate.

However, you can now discover cashews cultivated in numerous countries that enjoy tropical climates.

The cashew tree was first exported from Brazil to Goa, India by the Portuguese between 1560 and 1564.

As time evolved, the tree continued to extend its presence to both Southeast Asia and Africa where it is still grown today.

In the early 1970s, the majority of global cashew production (68 percent) happened in Africa, specifically Mozambique (a previous Portuguese colony) and Tanzania. Since then cashew production has shifted to Asian countries, with Vietnam being the largest exporter of cashews for the final 11 years.


Why Cashew Shells Are Poisonous

Raw cashews contain urushiol, a resin that is toxic if ingested and can cause rashes or burns if it contacts the skin.

To remove this substance, cashews must go through a rigorous roasting or steaming process to ensure they are safe to eat.

What is a cashew allergy

This is why you will always see cashews shelled at the grocery store.

Before that roasting process, however, cashews are a beautiful shade of green!

Cashews belong to the same family as mangos, poison ivy, and pistachios.

The harmful part of the cashew (which can also be found in mango plants) is the same ingredient that makes poison ivy poisonous.


Are Cashews Excellent for You?

Cashews are an excellent source of micronutrients, i.e. vitamins and minerals including copper, manganese, magnesium and phosphorous, vitamin K, iron, and zinc.

A 28-gram (1-oz) serving of dry roasted cashews provides 9 percent of the recommended daily worth of protein, but also 8 percent of the daily worth of calories.

As always, remember that nuts are high energy thick foods, so a little goes a endless way!


Cashews in the Kitchen

Cashews are well known for their wealthy buttery flavor and texture.

They are widely used in Asian cuisine and are an ingredient in numerous stir-fry dishes.

Cashews are increasingly favorite in the making of dairy replacements, such as cashew ‘butter’, cashew ‘milk’, cashew ‘cheese’, and cashew ‘ice cream.’

They are also an excellent ingredient for thickening sauces.

If you are looking for a grand cashew recipe, here is one of our favorites called Roasted Pear Crostini With Cashew Cream.

Enjoy and Happy National Cashew Day!

Note: The above lists are not finish and may change.

Emerging Allergen Reporting Tool

If your kid has had a reaction in the final 12 months to a food other than a priority allergen, participate in an significant research survey. Your participation will assist researchers, and advocacy groups love ours, better understand emerging allergens.

Be Allergy-Aware: How to avoid tree nuts

  • Read ingredient labels every time you purchase or eat a product. If the label indicates that a product “Contains” or “may contain” tree nut, do not eat it. If you do not recognize an ingredient, if there is no ingredient list available, or if you don’t understand the language written on the packaging, avoid the product.
  • According to Health Canada:
    1. If a tree nut is part of the ingredients, the specific tree nut(s) must be declared by their common name (almond, Brazil nut, etc.) in the list of ingredients or in a separate “contains” statement immediately following the list of ingredients.

  • Do The Triple Check and read the label:
    1. Always carry your epinephrine auto-injector. It’s recommend that if you do not own your auto-injector with you, that you do not eat.
    2. Be careful when buying imported products, since labelling rules differ from country to country.
    3. Once when you get home and put it away.
    4. Check with manufacturers directly if you are not certain if a product is safe for you.
    5. Once at the store before buying it.
    6. Again before you serve or eat the product.
    7. Watch for cross-contamination, which is when a little quantity of a food allergen (e.g., almond) gets into another food accidentally, or when it’s present in saliva, on a surface, or on an object.
