Artificial Antioxidants

Updated: May 4

Low-quality fats in kibble oxidize quickly and cause oxidation stress in the body. Therefore kibble manufacturers are adding artificial antioxidants to attempt to combat this oxidative stress.


Why Antioxidants Are Added

Quality fat is essential, but many studies have shown poorly balanced fats to behavior problems, hormonal problems, weight gain, insulin sensitivity, gut issues, and more. Fat is also added to dry foods for palatability.


Researcher Dr. Andrew Mente from McMaster University said: “Our data suggests that low-fat diets put populations at increased risk for cardiovascular disease."


Fats are made of 3 molecules of fatty acids and 1 of glycerol. These dietary fats are broken down depending on the number of double bonds in the fatty acids. Saturated fats have no double bonds, while unsaturated have 1 or more double bonds.


The more double bonds a fatty acid has, the more unstable and the more oxidation stress occurs. This is why Polyunsaturated Fatty Acids (PUFAs), also known as omega 3s, oxidize rapidly. Once the bag is open, the fats turn rancid, so the omega 3s are not longer omega 3s and turn into something that may be very harmful to dogs/cats.


When a kibble bag is open, the food has around 2 weeks to be used before the fast all turn rancid. According to USDA, foods with saturated fats can only be frozen for 3-4 months until they begin to lose quality.


This drives pet food companies to add antioxidants to slow oxidation and oxidative stress from low-quality fats.

Synthetics are made by pharmaceutical (big pharma), not food companies. Brandy Vaughan, who ruan Learn The Risk, a non-profit that shares the dark truths behind Big Pharma, reveals how twisted and profit-driven the vaccine and drug industry is.


Here are the most commonly used synthetic antioxidants. All are used to extend shelf-life and slow oxidation:


  • BHA (butylated hydroxytoluene)

  • BHT (butylated hydroxyanisole)

  • Ethoxyquin

  • BHQ (tertiary butylhydroquinone)


BHA/BHT: classified as a human carcinogen, endocrine disruptor, a chemical cousin to BHA (BHT).
