A low FODMAP diet may help those with bloating, gas, constipation, diarrhea, stomach pain, and IBS (irritable bowel syndrome).

Is nutritional yeast sustainable?

Is nutritional yeast sustainable?

Nutritional yeast production is relatively destructive due to air pollution. Nutritional yeast production releases acetaldehyde, one of a group of chemicals known as the volatile organic compounds (VOCs). Acetaldehyde is a chemical similar in chemistry and toxicity to formaldehyde. The EPA (Environmental Protection Agency) has identified acetaldehyde as the hazardous air pollutant (HAP) emitted in the largest quantities from the manufacturing of nutritional yeast, which is classified as a carcinogen (although carcinogens are not a component of the finished product).

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.

Is nutritional yeast vegan?

Is nutritional yeast vegan?

Yes, nutritional yeast is vegan. Nutritional yeast is a deactivated yeast, a type of fungus, 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 nutritional yeast have human rights issues?

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

At this time there have been no major concerns with nutritional yeast 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. 

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 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.
