Oat milk…
- May involve worker exploitation, laborer issues, human rights concerns
Where does most oat milk come from?
The world’s leading producer of oats is Russia, followed by Canada, Poland, Australia, Finland, The United States of America, Brazil, Spain, United Kingdom and Argentina.
Overall oats are planted in more than 70 countries world wide.
Is oat milk nutritious?
Yes! Oat milk is high in fiber, beta-glucans and often enriched with nutrients including calcium, potassium, iron, and vitamins A and D.
Is oat milk gluten free?

Yes, oat milk is typically gluten free but oats can often be cross-contaminated with wheat and therefore, contain gluten. Be sure to check specific brand gluten free labeling if necessary.
While celiac disease may not be as rampant as many marketing trends lead us to believe, you may have a gluten sensitivity…
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.

Is oat milk a common food allergen?

No, oat milk is typically not a common food allergen but oats are often cross-contaminated and contain the common food allergen: wheat. Many people experience allergic reactions to wheat contaminated oats.
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.

Is oat milk low FODMAP?

Yes, oat milk is low FODMAP, a beverage that fits into 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 oat milk?

Oat milk likely has a relatively moderate water footprint compared to other foods and beverages.
It takes 2,416 liters of water to produce 1 kilogram of rolled oats / 290 gallons of water to produce 1 pound of rolled oats.
Did you know that water is a finite, non-renewable resource?
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 oat milk?

Oat milk likely has a relatively low carbon footprint compared to other foods.
It takes around 1.0 kg CO2e to produce 1 kilogram or 2.2 pounds of oats, a car driving equivalent of 2.5 miles or 4 kilometers.
Food not only has a water footprint but also a carbon footprint, known as CO2e, which stands for carbon dioxide equivalent. Since carbon measurements are a bit more difficult to comprehend, it is common to equate CO2e to the distance which a car drives in miles or 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

Is oat milk sustainable?

Yes, oat milk 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.
Is oat milk vegan?

Yes, pure oat milk is vegan. Oat milk is made from oats, a cereal grain, and not an animal product or byproduct, therefore making it a vegan food.
Animals of factory farming 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. Growth hormones allow all kinds of animals to become fatter faster and live short lives.
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.

Does oat milk have human rights issues?

At this time there are no major concerns with oat milk 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 can 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.
