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.

Mosquitoes also suck things other than human blood. What are they?

When you think of mosquitoes, the first thing that comes to mind is probably “sucking blood.” But in fact, they drink more than just blood.

So what else do they drink? Here’s a hint: something sweet.

The answer is… flower nectar.

Mosquitoes actually sip nectar regularly to replenish their energy.

Only females drink blood, and only because they need it to develop their eggs—males drink nectar exclusively.

Learning a new side of a familiar creature can spark conversation and stimulate the brain while enjoying the feel of the season.

It’s a tidbit you’ll remember the next time you hear that buzzing sound in the summer.

What is the reason we don’t eat eel as sashimi?

Let’s think simply! Here’s a trivia quiz: Why don’t we eat eel as sashimi? While there are many kinds of fish served as sashimi, eel is never offered that way.

The answer is: because eel blood contains toxic substances.

Eel blood has a toxin called ichthyotoxin (ichthyohemotoxin), which can cause symptoms like nausea and abdominal pain if ingested.

That’s why eel should always be cooked thoroughly before you enjoy it.

What ingredients help prevent food poisoning when included in a bento?

Here’s a trivia quiz: Which ingredient helps prevent food poisoning when packed in a bento? As temperatures rise, food poisoning from lunch boxes becomes a concern.

The ingredient said to help prevent it is umeboshi (pickled plums).

Umeboshi, rich in salt and citric acid, has strong antibacterial effects, making it a good addition to bentos.

However, it’s best not to rely on umeboshi alone—use it together with ice packs and an insulated bag.

A handy tip for the warmer seasons.

In sukiyaki, which ingredient is considered better not to place next to the meat?

A quiz many people might already know! In sukiyaki, which ingredient is said to be better not placed next to the meat? Here’s a bit of trivia for you.

The correct answer is shirataki (konjac noodles).

Shirataki contains calcium, and when it comes into contact with protein, heat coagulation occurs, which causes the meat to toughen more quickly.

To enjoy delicious, tender meat, it’s important to be a little mindful of how you arrange the ingredients.

What do you call the black spots that appear on a banana peel?

The black spots that form on banana peels are called sugar spots.

Sugar spots are a sign that a banana has ripened and become delicious.

When the sugar spots spread all over and the peel becomes slightly soft, it’s said to be the ideal time to eat the banana as is.

You can also peel it, wrap it, and freeze it to enjoy in smoothies, cooking, or as a refreshingly cold banana ice treat.

Give it a try! Knowing the tips for when bananas are at their tastiest will help you enjoy even more delicious bananas.

What is the reason melons develop their net-like patterns?

It’s said that the net-like pattern on melons forms to prevent the skin from cracking.

After pollination, melon fruits grow extremely rapidly from the early to middle stages.

As the flesh expands quickly, cracks appear in the skin, which cannot stretch enough.

This is the beginning of the net pattern.

The cracks do not form all at once; as the fruit continues to enlarge, new cracks appear one after another, and the repeated process of these cracks healing creates the intricate net-like pattern.
