‘Paws, Claws, & Laws: Tails of Regulations, Advocacy, and Proper Labeling’

Healthy Pet Products is excited to present, “Paws, Claws, and Laws: Tails of Regulations, Advocacy, and Proper Labeling.” This full day event will feature industry experts who will be discussing the importance of what and how we feed our pets, what it means to be your pet’s advocate, and how to navigate through pet food ingredients. We will explore the benefits of holistic healing, the science behind food as medicine, how pet foods are prepared, and why we must continue as their advocates!

Our all-star lineup features local and national experts in the fields of holistic veterinary medicine, food science, industry regulations, and consumer advocacy:

Dr. Doug Knueven of Beaver Animal Clinic

Your Vet’s Pet Food Misunderstanding


As explained in last week’s blog, determinism is the belief that any subject can be best understood by understanding its parts. When determinism is applied to nutrition you get the kind of silly statements that veterinary nutritionists and pet food manufacturers make all the time. These experts will tell you that it is not the ingredients of a pet food that matter but rather it is the nutrients.

Of course, if you believe in the reductionist view that we understand food best by studying its parts, then it does not matter what ingredients provide the calories, protein, and other nutrients. This is the kind of nutrition information that gets spoon fed the veterinary students who become your local pet nutrition experts (your vet). And we all have swallowed it hook, line, and sinker. This belief is also what justifies the poor ingredients in the foods veterinarians often recommend.

Such ingredients as “Whole Grain Corn, Corn Gluten Meal, Whole Grain Wheat, and Brewers Rice” are among the first listed in one feline prescription diet. Now, grains and starches of any kind are not appropriate for pets – especially cats, which are known to be obligate carnivores.  And, the protein provided by grains is of poor quality (inappropriate amino acid profile and inadequate absorption).

The notion that nutrients rule is refuted in this research published in the journal, Nutrition Reviews. The title of this article says it all; Food, Not Nutrients, is the Fundamental Unit in Nutrition. Here is what the researchers have to say.

It seems a good assumption that the vast majority of components of plant and animal-based food is functional, that it has some kind of biological activity…there are thousands of other substances [besides vitamins and minerals] in the food matrix that must be considered as possibly leading to biological activity, possibly synergistically with each other, that in some sense could equally be deemed essential for life because they are not produced by nor do they augment human biological systems.”

Between the number of nutrients in food and the way the body selectively absorbs and utilizes them, nutrition is much more complicated than the veterinary nutritionists and pet food manufacturers lead us to believe. I will write more on that next week along with the solution to the nutrition problem.

Read your pet’s food ingredient label and let us know what questionable things you find.

The Mystery of Homeopathy Explained


Most homeopathic remedies are very dilute. In fact any homeopathic remedy of 24X or 12C potency and above has been diluted to the point that statistically speaking, not even one particle of the original substance remains. Herein lies the major complaint about homeopathy.

We are all very familiar with the pharmacological, linear, dose-response curve. A small dose of medication causes a small effect and the larger the dose, the larger the effect. So, the more dilute the medication, the more reduced the biological effect. At very low dilutions no effect is expected. Diluting a medicine to the point that statistically there is none of the original substance left, certainly results in it having no biological effect. Therefore, homeopathy is quackery – so the thinking goes.

This conclusion is valid given the assumption that homeopathic remedies are ordinary dissolved and diluted bulk-form pharmaceutical chemicals that act pharmaceutically with linear dose-response activity. However, modern research disproves these assumptions.

Recently, numerous laboratories around the world have studied high-potency homeopathic remedies (those diluted beyond Avogadro’s number) using many analytical techniques. Specific high-potency remedies have been found to differ from each other and from succussed solvent controls in their release measurably excess heat and electrical conductivity.1,2 They have been shown to differ using Ramen and UV-vis spectroscopic methods,3,4 NMR spectroscopy,5 infrared spectroscopy,6 REDEM technology,7 gas discharge visualization,8 and thermoluminescence.9 Clearly, even though high-potency homeopathic remedies are void of chemicals that can be detected conventionally, there is evidence that they contain some unique information. The answer may lie in the budding science of nanoparticles (NPs).


NPs are particles measuring in the range of one-billionth of a meter in any external dimension. For perspective, typical body cells range from 1-100 micrometers in diameter. NPs range from 1-100 nanometers and there are 1,000 nanometers per micrometer.

PNs have different properties than their bulk forms. Any compound that is not in a NP form is a collection of atoms or molecules. The outer surface molecules are available to react chemically while the interior remain inactive. NPs have a high percentage of exterior, reactive molecules compared to their bulk forms and they have a higher surface area. One kg of particles of 1 mm3 has the same surface area as 1 mg of particles of 1 nm3. Their increased surface area combined with their small size contribute to NPs unique properties including adsorptive, electromagnetic, optical, thermal, and quantum properties, as well as increased chemical reactivity, bonding, high conductivity, strength and durability.10-17


In vivo, NPs can easily penetrate the body’s usual barriers including the skin and blood-brain barrier, as well as the lining of the GI tract and airways. NPs of a compound can have different toxicological profiles than the bulk form because of their size and unique chemical characteristics. Due to the increased bioavailability and reactivity of NPs the dose needed for their biological activity is lower than that needed for herbs, nutriceuticals, drugs, or antigens by orders of magnitude.12,18-21

Like modern methods for producing nanoparticles, the succussion used in homeopathic remedy production causes intense turbulence, particle collision, and shear forces that break the source material into smaller and smaller particles.22 The result is the production of remedy source NPs. In fact, remedy source nanoparticles have been detected in commercially produced, high-potency, homeopathic remedies.23,24

It appears that the more succussion and dilution a homeopathic remedy is exposed to (the higher its potency), the more NPs are produced and the smaller those NPs become. Cellular interactions with NPs can cause systemic effects.25 The NPs in homeopathic remedies may therefore act as low level stressors of the body, thereby triggering a systemic stress response.
