How Free Radicals Develop In Dog Food

Frozen raw meat vs dry kibble.

An interesting challenge exists in trying to determine the free radical formation in raw meat diets and dry kibble formulas. We know that the development of free radicals are detrimental to health and the formation of disease. We are justified in making differences between a heat processed dry diet and one that has had little or no heat used in the manufacturing process. A big concern is the oxidation of lipids and essential fatty acids. I agree that when a frozen diet is ground, mixed, exposed to air, light, and other elements found in plant and animal tissue that some free radical formation happens, however, in any process whether frozen or dry there is similar exposure to this toxin formation problem.

One of the biggest concerns I have in the manufacturing of a dry kibble formula is the development of lipid oxidation, mold contamination, and pesticide control. For this reason, they use preservatives and a variety of harmful chemicals to inhibit the growth and contamination of these ingredients. How else could a consumer keep a bag of kibble from spoiling after being opened for 30 days? There are more reasons to be concerned, in your pet food choice, when comparing a raw pet food versus a heat processed kibble diet. Trying to indicate that lipid oxidation in a raw diet is a major concern is potentially true to some extent, but minimal in comparison to the possible toxin development in a dry kibble product.

I’m against the harmful exposure to preservatives, flavoring agents ( fat sprays), mold inhibitors, and other harmful chemicals that are used to either preserve the integrity of the dry product or enhance the palatability of the product. It would be an interesting research project to isolate the specific differences in free radicle formation between the two choices. Until that time, the choice is yours to determine the best source of ingredients and manufacturing process to feed your dog. I know what my choice is!

  1. Not to mention that dog foods here in Canada at least, have a shelf life of 18 months. What kind of preservatives & chemicals are they spraying on the kibble to give it an 18 month shelf life?!

  2. Thanks for sharing this information with us dog owners and I did not know how dry Kibbles was bagged and put together. Im glad that you have shared your knowledge about this with us. I want to invite you to visit my dog blog I think you will find alot of my posts interesting and there is also alot of funny dog pictures and dog poems I know you will enjoy reading. I also post alot of home remedies for dogs, so I invite you to visit and when you do please be sure to click on my adgitize ads Im new to adgitize but the clicks help towards buying dogfood and giving shelter to abandoned dogs I take in and care for.

  3. Thank you both for your comments. I don’t see any responses in favor of the dry food advocates. Is it possible that they are in agreement with me now?
