Vegan. Organic. Non-GMO. Gluten-Free. Climate Pledge Friendly. Economical. Eco-Friendly. We love it!
Where do most green onions come from?
The world’s top green onion producing country is China, followed by Japan and Mali.
The world’s top green onion exporting country is China, followed by Netherlands, Spain, Belgium, Mexico, Italy, Morocco, France, Germany and USA.
Are green onions nutritious?
Green onions are high in vitamin K, vitamin A, vitamin C, and folate.
Other names for green onions include scallions and spring onions.
Are green onions alkaline or acidic?

Green onions are alkaline.
What is the pH level of green onions? Green onions have a 7.5 pH level once digested.
When you eat food, it breaks down to an ash residue that can be neutral, acidic or alkaline. Minerals such as potassium, calcium, magnesium, sodium, zinc, silver, copper and iron produce an alkaline ash; whereas sulfur, phosphorus, chlorine and iodine, which are found in meat, coffee, dairy and alcohol, leave an acid ash.

Are green onions gluten free?

Yes, green onions are gluten free. Green onions do not contain gluten. Green onions are a type of vegetable, therefore making it a naturally gluten free food.
Celiac and gluten sensitivity symptoms are similar and may include:
- recurring abdominal pain
- chronic diarrhea
- constipation
- tingling
- numbness in hands and feet
- chronic fatigue
- joint pain
- unexplained infertility
- low bone density (osteopenia or osteoporosis)
There are hundreds of potential symptoms, many of which are also symptoms of other conditions.

Are green onions a common food allergen?

No, green onions are not a common food allergen. Some people may experience allergic reactions to green onions but it is relatively rare by comparison.
A group of the eight major allergenic foods, AKA the Big-8, include:
Severe food allergies can be life threatening. Following ingestion of a food allergen, a person with food allergies can experience a severe, life-threatening allergic reaction called anaphylaxis.
Persons may still be allergic to and have serious reactions to foods other than the eight foods identified by the law.

Are green onions low FODMAP?

The green tops of green onions are low FODMAP and ok to eat if you are on a low FODMAP diet. However, the white part or bulb of green onions is high FODMAP, which you should avoid and not eat if on a low FODMAP diet.
A low FODMAP diet may help those with bloating, gas, constipation, diarrhea, stomach pain, and IBS (irritable bowel syndrome).
It’s all about knowing your body. Observe what works and what doesn’t. You body might even react negatively to a low-FODMAP food simply due to intolerance. Everyone is different! Be mindful and patient. Take time to get to know what’s best for your physical health and overall wellbeing.
Water footprint of green onions?

Green onions have a relatively low water footprint compared to other foods.
It takes 272 liters of water to produce 1 kilogram of green onions / 33 gallons of water to produce 1 pound of green onions.
Did you know that water is a finite, non-renewable resource? Once it’s gone, it’s gone!
How much water does it take to produce an apple? A serving of rice? A steak dinner?
We need to be aware of something referred to as a “water footprint”. That is, the amount of fresh water utilized in the production or supply of goods we consume. As it turns out it takes significantly more water to yield foods that come from animals than foods that come from plants. Imagine how much water a cow needs to consume to generate a piece of beef. Not only how much water a single cow drinks, rather all the water that went into producing the crops that the cow ate.

Carbon footprint of green onions?

Green onions have a relatively low carbon footprint compared to other foods.
It takes 0.5 kg CO2e to produce 1 kilogram or 2.2 pounds of onions, a car driving equivalent of 1.25 miles or 2 kilometers.
When calculating carbon emissions, some factors may include…
- farm equipment
- animal feed production
- hothouses (greenhouses)
- food processing
- packaging
- transport
- refrigeration
- freezing
- package waste and more
But that’s not all!
It’s best to keep the following in mind when grocery shopping:
- shopping locally reduces transportation emissions
- food without packaging reduces waste as well as the carbon footprint
- refrigerated and frozen foods increase carbon emissions
- seasonal foods reduce carbon emissions from hothouses (greenhouses)
- growing plant-based foods at home is the most environmentally sustainable method with zero carbon footprint

Are green onions sustainable?

Yes, green onion production is relatively sustainable since there is no known significant damage to air, water, land, soil, forests, etc. as long as pesticides have not been used. Be sure to buy non GMO/organic, as toxic, chemical pesticides contaminate air, water, soil, etc. when using regenerative practices.
A 2018 Oxford University study – which is the most comprehensive analysis to date of the damage farming does to the planet – found that ‘avoiding meat and dairy is the single biggest way to reduce your impact on Earth’ as animal farming provides just 18% of calories but takes up 83% of our farmland.
Consuming animal products and byproducts is not environmentally friendly and is one of the worst things for the Earth. Not only is meat production wasteful, it causes enormous amounts of pollution. The industry is one of the biggest causes of climate change.
United Nations reports that a global shift towards a vegan diet is vital to save the world the worst impacts of climate change.

Are green onions vegan?

Yes, green onions are vegan. Green onions are a vegetable and not an animal product or byproduct, therefore making it a vegan food.
According to Sentient Media, “more than 200 million land animals are killed for food around the world every day. Including wild-caught and farmed fishes, we get a total closer to 3 billion animals killed daily.”
Animals of factory farms and the livestock industry are suffering. They live in horrific conditions that often include confinement, physical abuse and unnatural environments…so much so that they need to receive antibiotics to keep from getting ill or spreading disease. They’re also injected with growth hormones to become fatter faster and live short lives, being slaughtered as soon as they finish growing and are killed prematurely, well before their natural lifespan.
Because we cannot see for ourselves how these animals live and what they endure does not mean it isn’t happening. The meat, poultry and dairy industries do everything they can to distance us from knowing how our food comes to be in order to keep us in the dark about what we support each time we buy animal derived products and byproducts.
Go vegan for animals!
It’s the best way to help animals and it’s not as difficult as you may think. Speak for animals with your actions, for they cannot speak at all.

Do green onions have human rights issues?

At this time there are no major concerns with green onion production but that doesn’t mean it isn’t happening!
It’s important to stay aware of human rights concerns and worker exploitation that may come with specific brands.
Did you know the single largest employer in the world is agriculture? The labor involved behind each and every product cannot go unrecognized.
Some known problems include workplace health and safety, child labor, gender inequality, inadequate pay, wage theft and exploitation. Workers may even experience harassment, humiliation and violence and unfair employers often fail to provide laborers with access to shade, drinking water, restrooms and breaks. Consequently, laborers can face nausea, dizziness, heat exhaustion, dehydration and heat stroke -the leading cause of farmworker death!
Such mistreatment is like modern day slavery. Workers are often afraid to report issues because they fear it will result in losing their jobs or deportation. Fair trade organizations fight to ensure better social, environmental and economic standards.
We can improve people’s lives with foods we eat every day simply by buying products that are certified fair trade.
