I’ve been working as a certified care worker for 17 years. I’m Nanaka, a caregiving web writer. I decided to pursue this profession because I wanted a job that would help people. Having worked in day care for many years, I’ve experienced a wide variety of recreational activities. Exercise set to music, in particular, always created a cheerful atmosphere and was very well received. I’d be delighted to continue delivering writing that resonates with readers through caregiving-related articles. Thank you for your support.

If you heat a certain item in the microwave, it will remove unpleasant odors inside. What is that item?

One home appliance that everyone uses is the microwave.

It’s a very convenient item, but since we put food in it, there’s the downside that it tends to get smelly.

We try cleaning it to get rid of the odor, but it can be hard to remove.

There’s a handy method to know for times like that.

Believe it or not, simply heating used tea leaves will eliminate the smell.

This works because of the catechins contained in tea.

By the way, if you leave the microwave closed for a few minutes after heating, it becomes even easier to remove the odor.

Why is it that we don’t eat eel raw?

Eel has long been loved by the Japanese.

Dishes like unajū (eel over rice) and grilled kabayaki come to mind as delicious favorites.

However, you’ve probably never seen eel eaten raw.

Do you know why? It’s because eel blood is toxic, but the toxin is neutralized by heat.

As a guideline, heating at 60°C for 5 minutes makes it safe.

In recent years, processing techniques have advanced, making it easier to enjoy sashimi-style eel as well.

Take this opportunity to give it a try.

When you can’t stop coughing, drinking a syrup made by soaking a certain vegetable in honey can calm it. What is that vegetable?

The correct answer is “daikon radish.” A compound found in daikon called isothiocyanate has anti-inflammatory effects, and honey contains an enzyme called glucose oxidase.

This enzyme reacts with oxygen in the air to produce hydrogen peroxide.

Hydrogen peroxide, also known as “oxydol,” has disinfectant properties—the same “oxydol” used to disinfect wounds.

Based on this, “honey daikon” appears to help soothe coughs by disinfecting the throat and reducing inflammation.

The calves are also called the “second heart.” Using a part of the body, what is it called as the “second” what?

The calf, located on the back of the lower leg, has a nickname that uses the name of a body organ: “the second ___.” What is it? The hints are that it’s an internal organ and an indispensable organ not only for humans but also for animals.

The answer is the second “heart”! Blood tends to pool in the legs, but by actively moving the calves, blood circulates better and can be sent back to the heart more effectively.

That’s why they’re called the “second heart.”

When is the expiration date for the ice cream?

Chilled and delicious ice cream.

Many of you probably eat it often.

Here’s a question: do you know when ice cream expires? If you’re near a freezer, try taking out some ice cream and checking.

There’s probably no expiration date shown.

That’s because, in fact, ice cream doesn’t have a best-before date.

So you can technically eat ice cream that’s several years old.

However, that doesn’t apply if it has warmed up at some point or been opened.

Therefore, it’s basically recommended to eat it while it’s still new.
