Why I Don’t Recommend Brewer’s Yeast for Dogs and Cats



Going against the grain – find out why I don’t recommend Brewer’s yeast for dogs and cats, and discover safe, health supportive alternatives.



The Pet Food Industry and Pet Supplement Industry wants you to believe brewer’s yeast is good for your dog and cat.



The industry promotes brewer’s yeast as a highly desirable, editable substance that helps repel fleas, aids appetite, supports fur and skin health. All good right?



Wrong.



Truth…



The pet industry fails to divulge the rest of the story - the FACT that…



Brewer’s yeast can trigger and contribute to short-term, and long-term health issues and conditions.



There I said it.



So why would the pet industry ardently promote the use of brewer’s yeast? Maintenance of high profit margins. Brewer’s yeast is a very low-cost, readily available substance. 



What Is Brewer’s Yeast?



Brewer’s yeast is a type of one-celled fungus – scientific name “Saccharomyces cerevisiae”. The word Saccharomyces comes from the Greek word for sugar; and the fungus species name ‘cerevisiae’ comes from the Latin language, and means beer.



Saccharomyces cerevisiae was discovered thousands of years ago - perhaps during the making of bread. The Mesopotamians used a combination of sugar and water, fermented with the yeast to make an alcoholic beverage that later become known as beer.



Moving forward to Present Day, there are three main sources of Saccharomyces cerevisiae (Brewer’s yeast).

  

One – brewer’s yeast is still used by breweries to make beer.  Breweries cultivate the yeast on hops, malted barley or other grains. As the yeast sits in the grain-liquid solution to ferment, the yeast becomes contaminated. After the yeast has been used to ferment multiple times, the yeast microbes lose their viability, and are no longer useful to ferment beer. The inactive batch of yeast (now waste-yeast) must be replaced with new yeast.



Two - brewer’s yeast is also grown on molasses made from sugar beets or sugar cane specifically for the human and non-human-animal food and supplement manufacturing industry.



Three - Saccharomyces cerevisiae occurs naturally in the environment and is present in the gastrointestinal tract, on the skin of humans, and non-human animals including cats and dogs.



Brewer’s Yeast Use in Food and Supplements



Rather than discard the inactive waste-yeast breweries sell the inactive yeast to the food processing industry to be used as a food and supplement ingredient for humans, and non-human animals – farm animals, zoo animals, and domestic animals.



Brewer’s yeast is used in a wide range of made-for-pet products, including products marketed to you as ‘high’ quality, ‘all natural, ‘holistic’ and Veterinarian Prescription pet ‘food’, ‘treats’ and supplements.



Beneficial Properties of (inactive) Brewer’s Yeast
Protein (non-mammalian protein)
Vitamin B

Harmful Properties of (inactive) Brewer’s Yeast



Degraded, Toxic Source of Minerals, Protein, and Vitamin B

Most brewer’s yeast is cultivated on conventional grains. Glyphosate is sprayed on conventional grain to desiccate (dry-out) the crops prior to harvesting, it is also used on GMO grains, GMO sugar beets, and GMO sugar cane.  All of these crops are known to contain high levels of glyphosate residue. On March 20, 2015 the International Agency for Research on Cancer (IARC) released its findings on glyphosate. IARC’s conclusion - there is “sufficient evidence of carcinogenicity”. 


Non-organic and conventional crops are raised with synthetic chemical fertilizers that contain (toxic) heavy metals. The heavy metals are drawn into the plants via the root system and remain in the plant after harvesting.  Glyphosate, heavy metals an other toxins used in growing grain crops result in a crop that is deficient in nutritive value, and toxin-contaminated. The vitamins and minerals yielded from these crops are of poor quality - when Brewers' Yeast is cultivated on these crops the nutritional value of the brewer's yeast is also degraded, and contaminated with toxic residue.



Brewer’s Yeast – A source of MSG

The protein in Brewer’s yeast is a source of free glutamic acid – also known as MSG.

Glutamic acid (MSG) has an inflammatory effect on the brain that contributes to the onset of cognitive issues such as dementia. MSG is known as the 'silent killer'.



Brewer’s Yeast Contributes to Overgrowth of Bad Bacteria

If your dog or cat is prone to, or is currently experiencing an overgrowth of bad bacteria, Brewer’s yeast can worsen the overgrowth.



The truth the pet food and supplement industry does NOT want you to know - Brewer’s yeast IS an inflammation-promoting substance.



Brewer's Yeast Proven to Be Ineffective as a Flea Repellent

Inactive Brewer's yeast (this is the type of Brewer's yeast used by the food industry), proven ineffective as a flea repellent for dogs and cats. 

You Will Hear

You will hear people say, “since I put my dog on Brewer’s yeast his skin and fur is so much better” or “my dog isn’t getting so many fleas since I put her on brewer’s yeast”.

A dog may experience an improvement in one set of symptoms, but the dog or cat is also exposed to an increased toxic load, increased risk of inflammatory issues and conditions in the short and long-term.

While the Pet Industry profits, your cat and dog pay the ultimate price – degradation of his/her long-term health. A very unfair and unnecessary outcome when there are so many safe, affordable, alternatives.



Alternatives to Brewer’s Yeast



Supplemental Foods That Help Repel Insects and Parasites

There are many supplemental foods that can help your dog and cat be less-attractive to fleas.  These alternatives are inexpensive, readily available, and don’t have the adverse side effects that come with ingesting brewer’s yeast.

Important Note

1.0 Use of Foods, Herbs, Alternative Medicines:

Safe use of items and protocols in the article above, is your sole responsibility.

Foods, herbs and alternative medicines have health issue, condition and conventional drug interactions. Safe use of all substances and protocol are your responsibility.

Before you use any substance or protocol do your research. Check for cautions, contradictions, interactions and side effects. Do not use substances or protocols not suitable to your animal's individual circumstances.

If your animal has an underlying condition substances and protocols may conflict.

2.0 Definition of Holistic…

Food, herbs, alternative medicines are NOT ‘holistic’ they are a substance and MAY, or may NOT be ‘NATURAL’.

If you use a ‘natural’ substance (ie. an herb) you are using a natural substance, not a holistic substance.

Holistic is not defined by use of one or several substances. Holistic is an approach.

Definition of “holistic” from the Cambridge Advanced Learner's Dictionary & Thesaurus © Cambridge University Press

Adjective

"relating to the whole of something or to the total system instead of just to its parts"

"Holistic medicine attempts to treat the whole person, including mind and body, not just the injury or disease."

Holistic is a way of approaching life, and within that health, and well-being.

3.0 Expectation a natural substance remedies a health or behavioral situation.

A natural substance used to treat symptoms. But, if factors causing the underlying issue remain you do not have a remedy.

Remedy requires a comprehensive approach. It is necessary to identify root cause. Remove items that trigger, cause or otherwise contribute to issues. Holistic approach includes design, implementation to treat, remedy and maintain long-term health.
