Fun Fact Friday: Cashews

By
Education & Training with Although I'm retired, I enjoy sharing my knowledge and learning from other real estate industry professionals.

"Nature is full of surprises".

Did you know…
Those delicious cashews you snack on are actually related to poison oak?

Yes, it is true! Cashews belong to the same plant family as poison oak and poison ivy. Let that sink in for a moment. The very thing we associate with itchy, uncomfortable rashes shares a botanical connection with one of my favorite snacks. 

Furthermore, cashews aren't technically a nut at all. In the culinary world, they are classified as a nut, but they are actually just a seed.

Here is the good news.

The part that causes irritation, a natural oil similar to what is found in poison oak, is located in the shell surrounding the cashew, not the nut itself. In their raw form, cashews are not safe to eat. That is why every cashew you see in the store has already been carefully processed, typically steamed or roasted, to remove those harmful compounds.

In other words, your handful of cashews is perfectly safe, and thankfully, itch-free!

Here is an interesting twist. Mangoes and pistachios are also part of the same plant family. Ever noticed some people react to mango skin? Now you know why.

It is just another reminder that nature is full of surprises. Something that can cause irritation in one form can be completely safe and enjoyable in another.

Hello Carol - letting information of many sorts sink in isn't nuts - I see it as far from crazy.  It can be rather amazing to discover what can be found by digging deeper.  Now, let's continue to work on additional root concerns.

I love cashews, too, Nina Hollander, Broker 
When our son was in Iraq, I asked him what he'd like for his care packages. Pistachios was all he requested, which surprised me.

Carol Williams nuts are a good option in the heat of the desert.

I hadn't thought of that, but it makes sense.

Good morning Carol. My wife likes cashews and pistachios but I do not. Surprised to find out that Mangoes and pistachios are part of the same plant family. Nature is full of surprises. Enjoy your day.

Hi Wayne Martin

Now that is a fun fact.

It’s always interesting how something that sounds risky in one form turns into a favorite snack once it’s properly processed. I didn’t realize mangoes and pistachios were in that same family either.

Nature definitely keeps us learning.

I was aware of the poison aspect Carol Williams but you have opened my eyes to much more. I had no idea that they are not a nut or how they remove the poison. Thanks. Have a wonderful Easter weekend.

Good morning Carol,

Wow! I had no idea....I love cashews,  pistachios and mangos. I'm very allergic to poison ivy and had no clue!

Hi Dorie Dillard Austin TX 
I don't know anyone who isn't allergic to poison ivy, but I did a little more digging and apparently there are about 15% of people who aren't. Who knew?

I don't recall if this is why I heard what I had heard about cashews, but I remember hearing that they aren't necessarily good for us, haha.

Hi Brian England 
I don't think that's why. I think it's because cashews are high in calories and fat density. They can also cause kidney stone in sensitive people. I do love them!

Hello Carol Williams - I like that you referred to cashews as a "snack" and not a nut because they are not nuts.

Thanks for the nature lesson. We have a jar of cashews in our great room.  For me a couple are enough.

Hi Carol Williams - Every time I see or hear the words Cashews or Pistachios, I think of my dad. He loved eating both! It's times like this I wish I could talk to him to find out if he knew cashews were "belong to the same plant family as poison oak and poison ivy?" 

That is something I never knew. Isn't that interesting! Now that I think about it, I never saw a shell around a cashew. But I have seen and gotten into a lot of poison ivy and poison oak!
