ENVIRONMENT
Water footprint: likely moderate, it takes 4,345 liters of water to produce 1 kilogram of milk powder / 521 gallons of water to produce 1 pound of milk powder
Carbon footprint: likely high, 9.71 kg CO2e to produce 1 kilogram or 2.2 pounds of refrigerated powdered milk, a car driving equivalent of 22.25 miles or 35.75 kilometers
Destruction: high, casein production is relatively destructive, land usage for pasture, grain and forage, solid waste (excrement/manure) runoff into soil and freshwater, deforestation for feed crops, animal agriculture leading cause of: species extinction, ocean dead zones, water pollution and habitat destruction, responsible for up to 91% of Amazon destruction
Casein is…
- Unsustainable
ANIMALS
Kills: male calves, in most cases the dairy industry sells “unwanted” male calves to be slaughtered for veal, as pregnancy must occur for female cows to lactate and produce milk
Harms: cows, calves mother cow and calf distressed due to separation within 24 hours after birth, male calves slaughtered for veal, female calves fed artificially, locked in tiny cages, cows genetically modified to grow so obese that many become lame (unable to walk) shocked with electric prods, shackled with chains and dragged, beaten, prods poked up rectums, live last few months in crowded feedlots with hundreds or thousands of others, without pasture, often without shelter, must stand in mud, ice and their own waste, dairy cows eventually slaughtered for beef once milk production has ended
Indirectly kills or harms: ecosystems and wildlife, habitat contamination (water and soil pollution), wildlife habitat destruction (deforestation/land clearing), wolves and coyotes killed to prevent predation on livestock
Casein is…
- Not Vegan
- Harmful to wildlife and ecosystems
LABORERS
Health and safety: varies, overall, agriculture continues to be one of the most dangerous industries, farmworkers may be subject to dehydration, heat stroke, unprotected exposure to harmful, toxic chemicals and pesticides, unsafe machinery and clean drinking water may not always accessible
Living conditions: varies, laborers are often exploited, they may face tough working conditions including long hours in the sun and heat performing physically exhausting tasks, labor laws and rights may or may not be in place, even if worker protection exists, employer violations may go unreported, refugees and migrant workers are especially vulnerable to abuse and mistreatment, fearing consequences of job loss or deportation
Wages: varies, generally farmworkers earn meager wages, there are many cases of underpaid agricultural workers, wage theft and no overtime payment or benefits

Where does most casein come from?
The world’s top casein exporting country is Ireland, followed by New Zealand, France, Germany, Argentina, Netherlands, Ukraine, USA, Spain and Uganda.
Is casein nutritious?
Casein is high in protein but often contains antibiotics and hormones such as rBGH (recombinant bovine growth hormone) which is a genetically engineered synthetic hormone by Monsanto to increase milk production levels, resulting in cow mastitis infections, ultimately requiring more antibiotics.
casein is acidic.

Is casein alkaline or acidic? Casein is acidic. Dairy is an acidic food group.
When you eat food, it is broken 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.

casein is gluten free.

Is casein gluten free? Yes, casein is gluten free. Casein does not contain gluten.
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 and low bone density (osteopenia or osteoporosis).
There are hundreds of potential symptoms, many of which are also symptoms of other conditions.

casein is a common food allergen: milk.

Is casein a common food allergen? Yes, casein is a common food allergen: milk. Many people experience allergic reactions to casein.
A group of the eight major allergenic foods is often referred to as the Big-8 and includes milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans.
These foods account for about 90% of all food allergies in the United States.
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.

casein likely has a moderate water footprint.

Does casein have a high or low water footprint? Casein likely has a moderate water footprint.
What is the water footprint of casein? It takes 4,345 liters of water to produce 1 kilogram of milk powder / 521 gallons of water to produce 1 pound of milk powder.
Did you know that water is a finite, non-renewable resource? Once it’s gone, it’s gone!
We must do what we can to conserve fresh water and a major way to reduce needless water consumption is to change the way we eat. That’s not to say we need to reduce our water intake….quite the opposite. It’s important for our health to drink lots of water and eat foods that hydrate. The kind of water conservation we’re talking about here is behind the scenes.
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.

casein likely has a high carbon footprint.

Does casein have a high or low carbon footprint? Casein likely has a high carbon footprint.
What is the carbon footprint of casein? It takes around 9.71 kg CO2e to produce 1 kilogram or 2.2 pounds of refrigerated powdered milk, a car driving equivalent of 22.25 miles or 35.75 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 product emissions, some factors that may be included are… farm equipment, animal feed production, hothouses (greenhouses), food processing, packaging, transport, refrigeration, freezing, package waste, and more.
There are a number of steps that can be taken to reduce energy output. According to Oxford Martin School researchers, if the world went vegan, eliminating animal-derived products, it could reduce greenhouse gas emissions by two thirds and avoid climate damages of $1.5 trillion.
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

casein is unsustainable.

Overall, is casein eco friendly? Is casein sustainable?
Casein production is relatively unsustainable. There is significant damage to air, water, land, soil, forests, etc.
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.
A 2010 United Nations report said that a global shift towards a vegan diet is vital to save the world the worst impacts of climate change.
casein is not vegan.

Is casein vegan? No, casein is not vegan. Casein is dairy, the byproduct of a cow, therefore making it an animal-derived food. A mother cow’s milk must be used in order to produce casein.
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.

casein is a product that has labor issues.

Is casein a product with labor concerns? Yes, there are labor concerns with the dairy industry.
Did you know the single largest employer in the world is agriculture? The labor involved behind each and every product cannot go unrecognized.
Sadly, many labor concerns exist around the world in both developed and developing countries. We must be vigilant to ensure what we buy is not contributing to industries that are unfair to their valuable workers. Some known problems include workplace health and safety, child labor, gender inequality, inadequate pay, wage theft and exploitation. Workers can even be subjected to 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 has been likened to 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.
