walnut oil is acidic.

Is walnut oil alkaline or acidic? Walnut oil is acidic.

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 in meat, coffee, dairy and alcohol, leave an acid ash.

walnut oil is gluten free.

glutinous foods have side effects but a gluten free diet can help

Is walnut oil gluten free?

Yes, walnut oil is gluten free. Walnut oil does not contain gluten. Walnut oil is made from tree nuts, therefore making it a gluten free food. 

While celiac disease may not be as rampant as many marketing trends lead us to believe, you may have a gluten sensitivity…

Is walnut oil a common food allergen?

Yes, walnut oil contains a common food allergen: tree nuts. Many people experience allergic reactions to walnut oil.

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.

walnut oil likely has a moderate water footprint.

Does walnut oil have a high or low water footprint?

Walnut oil likely has a moderate water footprint compared to other foods.

It takes 4,918 liters of water to produce 1 kilogram of walnuts (with shell) / 589 gallons of water to produce 1 pound of walnuts (with shell), moderate, 5,293 liters of water to produce 1 kilogram of walnuts (shelled) / 634 gallons of water to produce 1 pound of walnuts (shelled).

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 “water footprints”. 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.

walnut oil likely has a low carbon footprint.

Does walnut oil have a high or low carbon footprint?

Walnut oil likely has a low carbon footprint compared to other foods.

It takes 0.76 kg CO2e to produce 1 kilogram or 2.2 pounds of conventional dry walnuts, a car driving equivalent of 1.75 miles or 2.75 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…

But that’s not all!

walnut oil is moderately sustainable.

Overall, is walnut oil eco friendly? Is walnut oil sustainable?

Walnut oil production is moderately sustainable. 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.

walnut oil is vegan.

benefits of vegan food to eat on a vegan diet which helps save animals

Is walnut oil vegan?

Yes, walnut oil is vegan. Walnut oil is made from nuts and not an animal product or byproduct, therefore making it a vegan food. 

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.

walnut oil may have labor issues and human rights concerns.

benefits of buying fair trade, labor rights, human rights and workers rights issues

Is walnut oil a product that has known labor issues?

At this time, there are no known specific reports of worker mistreatment regarding walnut farming but that doesn’t mean it isn’t happening. Walnut oil may or may not have labor issues.

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.
