Pest Attacks – You Aren’t The Only One Who Loves Onions!

If you’re considering being an onion gardener, you must be aware of the pest attacks that may occur, as you don’t want your hard work to go in vain.

Pests like nematodes, stem and bulb eelworm, thrips, and maggots usually attack onions. They are also very prone to diseases, like neck rot (fungal infection) and slimy outer scale (a bacterial disease). But, thankfully, there are always solutions available. So, to protect your plants, you can:

Beware When Handling Onions! – They Quite Literally Make You Cry

I’m sure you’ve heard of the concept of “crying while chopping onions,” and yes, my friend, that is quite the case! But why does a vegetable so worthy make you cry? Well, because they produce the chemical syn-propanediol-S-oxide, and when you cut them, a sulfur-based gas is released. The gas reacts with the moisture in your eyes and forms sulfuric acid, which stimulates the glands in your eyes to release tears.

But, this shouldn’t stop you from enjoying the benefits of onions, and for that purpose, a variety of hacks are available to help you avoid those tears.

For example, one way to avoid this is to wipe your knife with lemon juice before cutting it. Or, you can also chop your onion in a processor and turn it away while removing the lid or go the traditional way by chilling the onion before use, keep the root intact while cutting, and you’re good to go.

How To Store Onions At Your Home

The best place to store onions is at room temperature, preferably in a mesh bag. It would be best if you took care that the storage is dry and cold, so this place is usually a refrigerator in hot countries. Why should you do this? Well, because moist areas usually cause them to turn rotten and decay, so it’s essential to keep them in a dry environment. Furthermore, these fantastic veggies demand a particular place to be stored, as moisture from other vegetables can cause them to decay also.

Is It Safe To Eat / Consume Onions?

Yikes, you heard that right! Some people are at risk and should not consume them despite their many benefits. It’s easy to understand why we should avoid meat, but giving up on onions is shocking news, even among healthy eaters. Despite the many health benefits, onions are to be avoided by some. Unfortunately, yes, but fortunately, the chance you are among these people is rare.

As a quick reminder, I want to inform you that if you suffer from acid reflux, ulcers, heartburn, intestinal inflammation, or skin rashes, amongst other conditions, you better stay away from this plant!

The good news is that onion allergies are infrequent! If you don’t react after consuming them and don’t suffer from the health problems mentioned above, take advantage of these vegetables and eat them as much as you want! In moderation, of course.

Pregnant And Breastfeeding Women

If you’re wondering whether you should eat onions during pregnancy or breastfeeding, don’t worry. This plant helps to strengthen your immune system with the help of vitamin C in it. This applies to the mother who is expecting and to the unborn child.

Onions may have many health benefits but remember to use it in moderation to keep yourself and your unborn child safe. Because if you overeat them, you might have to deal with uncomfortable stuff like diarrhea and heartburn.

Children

You will be glad to hear that kids who eat onions tend to absorb iron from other foods better and enhance their immune system at the same time. But in a nutshell, everything is okay in moderation, so don’t let your kid only eat onions even though eating them a lot won’t be a significant health concern.

People With Allergies

Suppose you experience nausea or vomiting or any gastric problems after consuming onions. In that case, I have some bad news for you because you are allergic, or using the fancier term “intolerant.”

Other symptoms that might state an allergy are rashes or hives on your body. You can even feel tingling or itching in your mouth or swelling lips, tongue, face, or throat.

People With Diabetes

Thankfully, this plant is an excellent addition to the diet of a person who suffers from type-1 or people with type-2 diabetes. The reason is that consuming fresh onions lowers blood glucose levels. As simple as that!

Pets

As a new pet owner, you might be surprised to know that onions are poisonous to dogs and cats in all forms. It would be best if you didn’t give it to your pets because it breaks down their red blood cells, which can, in turn, lead to anemia. So, please don’t give them to your pets!
