Are You Using Your Onions Properly?

You may be overwhelmed at the grocery store sometimes wondering why there are so many different kinds of onions. If you’re like most people you probably gravitate towards yellow onions and use them for everything.

Health Benefits

Onions are part of the (italicize) allium (end-italics) genus. They’re not only delicious, they provide a wide range of nutrients including biotin, copper, vitamin B6, and vitamin C. They also provide fiber and a number of phytonutrients. All of which combine to make onions a great choice for health.

In addition to their anti-inflammatory, anti-bacterial properties, onions have also been shown to be useful for reducing cholesterol, lowering triglycerides and they can be supportive for lowering blood pressure.

Eating onions has also been shown to reduce the risk for certain kinds of cancers such as stomach and colorectal. Other studies have indicated onions have properties which can inhibit the growth of tumors.

If that weren’t enough, it turns out this nutritional powerhouse vegetable can also help support proper blood sugar levels. All of which makes this vegetable a really good choice to add to your diet. But which onion should you choose?

Storing Onions

Yellow onions are a really good all-purpose onion. But onions have a lot of personality. You can really punch up the flavor in your dishes when you choose and use different kinds of onions.

When it comes to storing them, most onions do best when stored in a cool, darker, well-ventilated space. Ideally, they should be stored either in a mesh bag or in an open container, not in plastic. This is so the air can circulate. Onions should be able to keep for approximately a month when stored this way.

Green onions such as leeks and scallions need to be stored in the refrigerator. They do best if they are wrapped so that they don’t dehydrate too quickly.

Once they have been cut all onions should be stored in the refrigerator. They’ll last for about a week.

Long-Term Storage

If you have an excessive amount of onions you can prepare them for long-term storage by either cooking them and then freezing, pickling, or preserving in someway, or slicing and dehydrating.

When to Avoid Onions

It kind of goes without saying, but if you are allergic to or sensitive to onions you should not eat them. If you do some food journaling and noticed that every time you eat onions (or garlic) that you have bloating, increased flatulence, or a change in bowel habits, it’s a good idea to avoid onions.

However, there are other times when you should not eat onions as well:

  • If you need to avoid FODMAP vegetables
  • When you are dealing with bacterial overgrowth in the gut
  • For anyone who needs to avoid sulfur-rich foods

No matter which onion is your favorite, be sure to use them all for variety and to take advantage of their nutritional support.
