About 25 years ago I began formulating pet foods at a time when the entire pet food industry seemed quagmire and focused on such things as protein and fat percentages without any real regard for ingredients. Since boot leather and soap could make a pet food with the “ideal” percentages, it was clear that analytical percentages do not end the story about pet food value. I was convinced then, as I am now, that a food can be no better than the ingredients of which it is composed. Since this ingredient idea has caught on in the pet food industry, it has taken on a commercial life that distorts and perverts the meaning of the underlying philosophy of food quality and proper feeding practices. Is health reducible to which ingredients a commercial product does or does not have? As contradictory as it may seem to what I have just said, no it is not. Here’s why.
The official Publication of the American Association of Feed Control Officials (AAFCO) gives wide latitude for ingredients that can be used in animal foods. As I have pointed out in my book, The Truth About Pet Foods, approved ingredients can include*:
undried processed animal waste products
polyethylene roughage replacement (plastic)
hydrolyzed poultry feathers
hydrolyzed leather meal
poultry hatchery by-product
meat meal tankage
ground almond shells
(*Association of American Feed Control Officials, 1998 Official Publication)
Simultaneously, this same regulatory agency prohibits the use of many proven beneficial natural ingredients that one can find readily available for human consumption such as bee pollen, glucosamine, L-carnitine, spirulina and many other nutraceuticals. It would be easy to conclude that reason does not rule when it comes to what officially can or cannot be used in pet foods.
From the regulators’ standpoint, they operate from the simplistic nutritional idea that the value of food has to do with percentages and that there is no special merit to any particular ingredient. They deny the tens of thousands of scientific research articles proving that the kind of ingredient and its quality can make all the difference in terms of health. They also are silent about the damaging effect of food processing and the impact of time, light, heat, oxygen and packaging on nutritional and health value.
The 100% Complete Myth
Consumers are increasingly becoming alert to the value of more natural foods. Everyone intuitively knows that the closer the diet is to real, fresh, wholesome foods, the better the chance that good health will result. Unfortunately, people do not apply this same common sense to pet foods. Instead they purchase “100% complete” processed foods, perhaps even going the extra mile and selecting “super premium” or “natural” brands, thinking they are doing the best that can be done. They surrender their mind to a commercial ploy (100% completeness) and do to their pets what they would never do to themselves or their family – eat the same packaged product at every meal, day in and day out. No processed food can be “100% complete” because there is not a person on the planet who has 100% knowledge of nutrition. The claim on its face is absurd. Understanding this simple principle is more important than any pet food formulation regardless of the merits of its ingredients. Everything that follows will begin with that premise, i.e., no food should be fed exclusively on a continuous basis no matter what the claims of completeness or ingredient quality.
Genetics Is The Key
Pets need the food they are biologically adapted to. It’s a matter of context. Just as a fish needs to be in water to stay healthy, a pet needs its natural food milieu to be healthy. All creatures must stay true to their design. What could be more obvious or simple? For a carnivore the correct genetic match is prey, carrion and incidental fresh plant material, and even some fur and feathers, as well as the occasional surprise of unmentionables found in decaying matter. It’s not a pretty picture to think that “FiFi” with her pink bow and polished toenails would stoop to such fare, but that is precisely the food she is designed to eat. Since that is her design, matching food to that design (minus the more disgusting and unnecessary elements) is also the key to her health.
