The-Truth-About-Pet-Foods

Dr. Wysong’s comments: The original safe amount of vitamin A was set at
10 times the requirement. Now we learn that even three times greater
amounts than this are safe. Not only may they be safe, but higher
levels of vitamin A may be important for health, since there is a good
chance that the minimum requirement is too low if the maximum is too
low. In any case, it is clear that the standards used for “100% completeness”
are at best good, but likely bad guesses.

Summary: “It is important to emphasize that the calculations made in the
formulation of a diet make a number of arbitrary assumptions and
the potential for significant error is high.”
Diets used: “Complete and balanced” premium processed pet foods.*
Dr. Wysong’s comments: “Arbitrary assumptions” cannot, of course,
add up to “100% complete.”

Protein requirements of dogs
J.V. Johnson, PhD
Summary: “The ideal level of protein intake for dogs is still a matter of
debate amongst nutritionists, veterinarians and breeders, with the recommendations
varying two- to three-fold..”
Diets used: “Complete and balanced” premium processed pet foods.*
Dr. Wysong’s comments: If something as fundamental as protein requirements
is not etched in stone, how is a “100% complete” fabricated
diet possible
* These results do not imply that the brands in these studies would be the only
ones to cause such problems. Any processed, manipulated, fraction-based
commercial food, fed exclusively, may risk disease.
