Yet these same companies promote their inferior products using deceptive packaging and claims their foods have been designed by experts to be complete replacements for a dog’s natural diet.
Welcome to what best-selling author Michael Pollan1 refers to as the Age of Nutritionism.
What Is Nutritionism?
Unlike nutrition, nutritionism is not a science. It’s an ideology. A religion-like philosophy, complete with believers who blindly follow each other off a cliff of common sense.
Nutritionism is an ideology that includes the misguided belief that scientists can engineer a food that’s better than that of Mother Nature
Followers of nutritionism believe the source and condition of the ingredients used to make any pet food have nothing to do with the quality of the finished product.
They insist that so long as the numbers and nutrient content of those ingredients meet certain criteria, a kibble can be designed to be a perfect replacement for fresh, real food.
Kibble — Better Than Nature?
But how can a factory-made food pellet be superior to a dog’s natural diet?
Notice the dramatically higher carbohydrate content of the kibble compared to a dog’s natural ancestral diet.
And the lower protein and fat content, too.
What’s more, pet food carbohydrates are frequently sourced from nutritionally empty cereal grains, menu items a dog’s ancestors would never have naturally consumed.
It looks like the pet food industry may have taken advantage of the dog’s remarkable ability to survive on just about anything.
Why a Protein Source Does Matter
Many nutritionists insist that protein is simply protein. And that it makes no difference from where that protein is sourced.
Yet to a dog, meat-based protein possesses a higher digestibility than plant-based protein.4
And animal protein has a higher biological value, too.
Dogs Eat Food — Not Nutrients
Today, thanks to nutritionism, instead of discussing food, pet food designers talk about nutrients. But when taken away from their whole food source, nutrients can behave differently.
For example, in humans, researchers have long observed that fresh fruits and vegetables can bestow a notable anti-cancer effect.
Yet when subjects are fed isolated vitamin supplements, scientists have been unable to consistently reproduce the same protective effect conferred by the whole food.
Why is this so? Why does whole food offer better health benefits than their component nutrients?
Do individual nutrients interact with each other in some unknown synergistic way?
Are the more favorable health effects of whole food related to the presence of other minor nutrients. Like enzymes or bioflavonoids?
Or to some other yet undiscovered micro-nutrient?
The Problems with
Many Commercial Dog Foods
Compared to fresh whole food, kibbles can frequently be…
- Light on meat
- Tinted with artificial coloring
- Preserved with synthetic chemicals
- Brimming with agricultural by-products
- High in cereal grains and other carbohydrates
- Supplemented with anonymous animal fat
- Laden with slaughterhouse waste
The Bottom Line
If you believe — like I — there’s something inherently wrong with using cereal mill rejects, floor sweepings, fatty meats, toxic preservatives and vegetable oil to make dog food, then here are a few things you can do to improve your dog’s meals…
- Practice diet rotation
- Favor meat-rich dog foods
- Avoid carbohydrate-heavy formulations
- Use canned or fresh meat toppers mixed with kibble
- Reject recipes spiked with plant-based meat substitutes
- Choose dog foods that mimic a dog’s natural ancestral diet
And don’t be an unquestioning follower of the cult of nutritionism.
Simply use your logic and common sense to see the shortcomings of this flawed philosophy.
As one of our blogging regulars used to say, it’s food — not rocket science.
