How many times are Ingredients cooked in Kibble Pet Foods?

    That actually sounds pretty good compared to what is actually going into the blender! I did want to point out that the “peas” in the dog food are most likely “field peas” not green peas that we eat as a veggie. Field peas are used in livestock feed and are higher in protein (5g vs 18g) and carbs (14g vs 40g). than green peas. I’ll bet all vegie matter enters the manufacturing plant dehydrated as it would then absorb the liquid from the meat and lessen the drying time. Good article. Thanks!

    From a Traditional Chinese Medicine perspective, every time the food is heated, it adds Heat. The result is it makes the body hot. So if kibble is heated (aggressively) 4 times, it leads to hot dogs and cats – they pant, drink excessive water and are hyperactive. It all ties together.

      That is a good way of looking at it. I have a “hot dog”. A fevering Shar Pei

    Purina is probably the top brand name. People tend to trust what they see advertised. Kibble is a quick and low-cost way to feed the family pet with no thought as to what it took to make meat into something stable. I’ve never fed any of my dogs kibble. My present dog gets a high quality canned dog food with a named meat as the first ingredient (and I’m on Social Security!). His stools are dark and firm, like wild canines who primarily eat meat. My son’s dog gets kibble. Her stools are light brownish-yellow with a mushy center. That’s a very big clue as to the quality of kibble vs canned!

      I’m on SS too and I don’t know how you can afford $3.00 a day for canned. I have two dogs to feed. I could never afford that on Social Security

    Of course people from extrusion manufacturers say baked is worse as it is cooked longer at higher heats creating more acrylamide, and baked folks say that extrusion is worse. Each of them may be using pre-processed ingredients like meat meals. Has anyone really looked at which methods thrash the nutrients more? Or which have higher levels of acrylamide?
    This is of course a major focus at our store, that all kibble is a highly processed food and that nothing beats whole foods for important nutrients that support health. But I still can’t find info about the nutritional differences between baked and extruded – have you found any?

      Both methods of cooking thrash the nutrients. Nutrients degrade with heat, and all enzymes in foods are destroyed when cooked at 117 degrees or higher. Considering kibble is cooked at over 300 degrees, you can pretty much assume all the healthy nutrients are dead. That’s why real, whole foods are so important. Kibble is the worst for our pets, even the “healthy” stuff.

    Thanks for breaking down the process! Not enough people give any consideration to the amount of processing that goes into kibble. All that heat destroys enzymes, denatures proteins, and makes the food carcinogenic (cancer-causing). It’s dead food in every sense of the word. And of course, that’s assuming they’re starting with beautiful, fresh, human-grade foods like those displayed on their packaging (which we all know they’re not). So much cheaper and better to feed real, fresh food instead. Will be sharing this, thanks!

    Well there was a step in between primarily canned food and kibble, and it was introduced by the Gaines-Burger folks. The product was an interesting hamburger looking meal you crumbled into the pets dish. No smell to humans, clean to the touch, kept in the pantry, yet “looked” meaty and seemed more tasty than “cereal” type PF. Quite novel at the time!! The PFI newsletter put out a very concise article on the history of PF. Long time ago it was rumored that canned PF was comprised of horse meat. Also WWII rationing (esp. tin) really pushed wet PF towards kibble.
