The Kibble Question: What Big Pet Food Doesn't Want You To Know

We've been duped about pet food the same way we've been misled about our own nutrition. For decades, we've accepted ultra-processed kibble as the gold standard for our dogs without questioning what's actually in those bags or how they're made. The parallels between the human food industry and pet food manufacturing are striking – and troubling.

The Uncomfortable Truth About Your Dog's Bowl

That bag of kibble sitting in your pantry probably isn't the nutritional powerhouse the marketing claims suggest. In fact, it shares more with ultra-processed human foods than most pet parents realize – foods now linked to chronic diseases, shortened lifespans, and diminished quality of life in humans.

The problem? Most commercial dog food undergoes extreme processing called extrusion – a high-heat, high-pressure method that destroys nutrients, denatures proteins, and strips ingredients of their natural goodness. What remains is a nutritionally depleted base that manufacturers then fortify with synthetic vitamins and minerals to meet minimum nutritional requirements.

It's the equivalent of eating a diet of Cheetos and multivitamins and calling it "complete nutrition."

But that's just the beginning of the problem.

The Ingredient List Shell Game

Take a moment to read your dog food's ingredient list. Notice phrases like "meat meal," "animal by-products," or vague terms like "animal digest"? These are industry euphemisms for what amounts to mystery meat – the leftover scraps from the human food supply chain.

While technically providing protein, these ingredients are a far cry from the whole, fresh meats your dog's ancestors evolved to consume. They're the hot dogs of the meat world – technically meat-adjacent, but not what anyone would call high-quality nutrition.

Then there are the fillers – corn, wheat, soy, and other cheap carbohydrates that bulk up the food but provide minimal nutritional value to your carnivore companion. Dogs simply don't need large amounts of these ingredients, yet they often form the foundation of commercial kibble.

The Dehydration Factor No One Talks About

Perhaps the most overlooked issue with kibble is its moisture content – or lack thereof. While a natural canine diet would contain approximately 70% moisture, kibble typically has just 10%. This chronic state of dehydration forces your dog's kidneys to work overtime and can contribute to urinary tract issues, kidney problems, and digestive complications.

Think about it: have you ever noticed how much more water your dog drinks when eating dry kibble? They're desperately trying to compensate for what their food lacks.

The Yale Connection You Can't Ignore

Recent research from Yale Medicine has drawn alarming connections between ultra-processed foods and human health issues, including increased risks of heart disease, mental health disorders, type 2 diabetes, and certain cancers. The definition of ultra-processed foods reads like a description of commercial kibble: industrial formulations created from substances extracted from whole foods, with chemical additives and minimal actual whole food ingredients.

The evidence suggests that these aren't merely correlations but causal relationships. The more ultra-processed foods humans consume, the higher their risk of developing serious health conditions.

Why would we expect different outcomes for our dogs?

Not Your Grandmother's Dog Food

It's worth noting that this kibble crisis is relatively new. Before the mid-20th century, dogs largely ate table scraps and leftovers from human meals – real, whole foods without preservatives or synthetic additives. The commercial pet food industry as we know it today emerged as a convenient way to monetize byproducts from human food production.

Marketing campaigns successfully convinced us that these processed products were superior to what dogs had thrived on for centuries. The convenience factor sealed the deal – pour and serve, no mess, no hassle.

But that convenience comes at a cost.

Better Options Exist

Fortunately, we're in the midst of a pet food renaissance. As more pet parents question conventional wisdom about kibble, alternatives have emerged:

Freeze-dried raw food** preserves nutrients without the high-heat destruction of traditional processing. By freezing fresh ingredients and then removing moisture, these products maintain more of their natural enzymes and nutritional integrity while offering the convenience of shelf-stable food.

Air-dried or dehydrated options** use low-temperature drying to preserve nutrients better than extrusion. They're lightweight, convenient, and typically higher in protein than conventional kibble.

Gently-cooked fresh food** services deliver pre-portioned meals made with human-grade ingredients, cooked at low temperatures to maintain nutritional value while eliminating pathogen concerns associated with raw feeding.

Home-cooked meals** give you complete control over your dog's nutrition, allowing you to prepare balanced meals using quality proteins, healthy fats, and nutrient-dense vegetables.

These alternatives aren't just fancy options for pampered pooches – they represent a return to species-appropriate nutrition that aligns with dogs' biological needs.

The Real Cost Calculation

Yes, these alternatives often come with higher price tags. But consider this: what appears more expensive at checkout might actually be more economical in the long run when you factor in potential veterinary bills for chronic conditions like obesity, diabetes, allergies, and kidney disease – all potentially linked to poor nutrition.

Moreover, many pets eat less of these nutrient-dense foods than they would kibble, partially offsetting the higher per-pound cost.

Think of it as an investment in your dog's long-term health rather than an expense.

Small Steps Toward Better Nutrition

You don't need to overhaul your dog's diet overnight. Small, incremental changes can make a significant difference:

1. Add fresh food toppers to kibble

2. Incorporate some freeze-dried meals weekly

3. Experiment with homemade additions to commercial food

4. Gradually transition to higher-quality options

Each step away from ultra-processed food is a step toward better health for your four-legged family member.

Trust But Verify

The pet food industry, like many others, excels at marketing. Terms like "premium," "natural," and "holistic" appear on packaging without regulatory definitions to back them up. Even "human-grade" can be misleading without careful scrutiny.

Become a label detective. Look beyond the attractive packaging and examine what's actually in the food. Seek out companies that voluntarily provide information about sourcing, processing methods, and quality control.

Most importantly, watch your dog. Improvements in coat quality, energy levels, stool consistency, and overall vitality can tell you more than any marketing claim.

The Bottom Line

The reality is simple: what we feed our dogs matters. Just as processed foods have contributed to a public health crisis in humans, ultra-processed pet foods may be setting our companions up for shortened lifespans and diminished quality of life.

We have the power to change this trajectory – one bowl at a time. Our dogs depend on us to make informed choices on their behalf. They can't read labels or research nutrition; they simply eat what we provide.

How do ultra-processed foods affect your health?

1. Briefing Document

I. Executive Summary

This document reviews the potential health risks associated with the consumption of ultra-processed foods (UPFs) for both humans and canines. A significant portion of the human diet in the U.S. consists of UPFs, and a large percentage of dog owners rely primarily on highly processed dry kibble. Emerging research suggests that high consumption of UPFs is correlated with a higher risk of various health problems. Alternative feeding methods, such as home-cooked meals, fresh food diets, and less processed commercial options, are presented as potentially healthier alternatives, although factors like cost and convenience are also considered.

II. Key Themes and Ideas

A. Ultra-Processed Foods (UPFs): Definition and Classification (Human)

Definition: UPFs are "industrial formulations made mostly or completely from substances (oil, fat, sugar, starch, and protein) extracted from food or derived from hydrogenated fats or modified starches. They can also be synthesized in laboratories with flavor enhancers, colors, and additives to make them highly palatable."
NOVA Classification: The NOVA system, recognized by the World Health Organization (WHO) but not the USDA, categorizes foods into four groups:
Group 1: Unprocessed or minimally processed foods (e.g., fresh fruits, vegetables, eggs, nuts).
Group 2: Processed culinary ingredients (e.g., oils, sugars, salt).
Group 3: Processed foods (e.g., freshly made cheeses, bacon, canned vegetables).
Group 4: Ultraprocessed foods (e.g., sweetened yogurts, breakfast cereals, packaged breads, pre-prepared pizzas).
Prevalence: UPFs make up "67% of calories consumed by children and teenagers" in the U.S.
Identification: "I would say that if the package has multiple ingredients and you can't identify some of them, it’s probably best to avoid it."

B. Health Risks Associated with UPF Consumption (Human)

Broad Correlation: A 2024 review in the British Medical Journal (BMJ) indicated that "eating more ultraprocessed foods is linked to a higher risk of dying from any cause and has ties to 32 health conditions, including heart disease, mental health disorders, type 2 diabetes, and other problems."
Specific Concerns: UPFs may replace more nutritious options, contain unhealthy additives, and increase the risk of chronic inflammatory diseases. The review authors add that ultraprocessed foods may contain contaminants with health implications that migrate from packaging materials, such as bisphenols, microplastics, mineral oils, and phthalates.”
Calorie Density and Palatability: "That makes people eat more of them, and they are more calorie-dense, meaning people are consuming more calories even when they are eating smaller amounts of food."
Study Example: A 2019 study showed that participants on a UPF diet consumed 500 more calories per day and gained an average of two pounds in two weeks, compared to those on an unprocessed diet.
Caveats: Dr. Imaeda notes that "the relative risks are not very high. They are 1.1-fold to 1.5-fold increases." However, even small increases can be significant for serious health problems. Additionally, many studies rely on patient surveys rather than controlled clinical trials.
Obesity Link: A significant question is the correlation between UPF consumption and diseases or diseases related to obesity, which obesity raises the risk of cancer, cardiovascular disease, and diabetes.

C. Ultra-Processed Foods (UPFs): Definition and Risks in Canine Diets

Prevalence: "Approximately 80-85% of dog owners primarily feed their dogs dry kibble/commercial dry dog food."
Processing: Kibble is made using extrusion at extremely high temperatures, destroying heat-sensitive nutrients.
Ingredient Quality: Many kibbles rely on low-quality meat meals, by-products, and fillers like corn, wheat, or soy.
Nutritional Imbalance: Kibble is often high in carbohydrates (40-60%), which dogs don't need in large amounts, potentially leading to obesity and insulin resistance.
Additives and Preservatives: Kibble contains synthetic preservatives, artificial flavors, and colors, some of which (like BHA, BHT, and ethoxyquin) have potential health risks.
Moisture Content: Kibble is typically only 10% moisture, potentially leading to chronic dehydration and urinary issues.
Contamination Risks: Grains in kibble can develop mycotoxins, and some kibble has been found to contain pentobarbital (a euthanasia drug) and heavy metals.
Long-Term Health Concerns: "Studies have suggested that a processed diet may contribute to chronic conditions like allergies, skin problems, digestive issues, inflammation, obesity, diabetes, and cancer."

D. Alternative Canine Diet Options

Fresh Food Diets: Studies suggest dogs fed fresh, whole-food diets may live 2-3 years longer. They typically show better dental health, healthier coats, and improved digestion.
Less Processed Alternatives to Kibble:Freeze-Dried Raw Food: Minimal processing, high in protein, easy to store and serve (e.g., Stella & Chewy's, Primal).
Air-Dried or Dehydrated Raw Food: Retains nutrients better than kibble, higher meat content (e.g., Ziwi Peak, Real Meat Company).
Gently Cooked Fresh Food: Fresh, whole-food meals lightly cooked (e.g., The Farmer's Dog, Nom Nom).
Fresh or Frozen Raw Food: Mimics a biologically appropriate raw diet (BARF or PMR) (e.g., Instinct Raw, We Feed Raw).
High-Quality, Low-Processed Kibble Alternatives: Air-dried, dehydrated, or baked formulas with whole-food ingredients (e.g., Carna4, The Honest Kitchen).

E. Home-Cooked Canine Diets

Key Components:Protein (40-50%): Lean meats, organ meats, eggs, fish.
Healthy Fats (10-20%): Fish oil, coconut oil, flaxseed oil, chicken fat.
Carbohydrates & Fiber (20-30%): Sweet potatoes, pumpkin, carrots, quinoa, brown rice, oats.
Calcium & Phosphorus Balance: Crushed eggshells, plain yogurt, cottage cheese, bone meal.
Essential Vitamins & Minerals: Leafy greens, berries, and supplements if needed.
Foods to Avoid: Onions, garlic, grapes, raisins, chocolate, xylitol, avocado, cooked bones, excessive salt, artificial additives.
Example Meal Plans: The document includes detailed five-day meal plans for different dog sizes and activity levels (toy breed, large breed, active medium breed).

F. Counterarguments from the Pet Food Industry

High-quality kibble contains all necessary nutrients and meets AAFCO guidelines.
Kibble is convenient, affordable, and shelf-stable.
Some brands use freeze-dried raw coatings or add probiotics.

III. Considerations and Recommendations

Human Health: While complete avoidance of UPFs may be unrealistic, awareness of their potential risks can help individuals make more informed dietary choices, prioritizing whole, minimally processed foods.
Canine Health: Pet owners should consider the potential long-term health impacts of kibble-based diets and explore less processed alternatives. Home-cooked diets can be a good option but require careful planning and knowledge of canine nutritional needs.
Cost and Convenience: Alternative diets can be more expensive and require more preparation time than kibble. A balance between nutritional quality and practicality is often necessary.
Further Research: More comprehensive, independent research is needed to fully understand the long-term health impacts of different diets (both human and canine) and to establish clearer guidelines for food processing.

This briefing document aims to provide a comprehensive overview of the current understanding of UPFs and their potential impact on health. It should serve as a starting point for further investigation and informed decision-making.

2. Quiz & Answer Key

1. What are ultra-processed foods (UPFs), and how are they classified using the NOVA system?

Ultra-processed foods are industrial formulations made mostly from substances extracted from foods (like oils, fats, sugars, starches, and proteins) or synthesized in laboratories, often with additives to enhance palatability. The NOVA classification system, developed by researchers in Brazil and recognized by the WHO, categorizes foods into four groups:

Group 1: Unprocessed or minimally processed foods (e.g., fruits, vegetables, eggs, lentils, fresh meat). These foods undergo minimal alteration, like cleaning or pasteurization, without the addition of ingredients.
Group 2: Processed culinary ingredients (e.g., oils, sugars, salt). These are extracted from natural foods and used in cooking.
Group 3: Processed foods (e.g., canned vegetables, salted nuts, bacon). These are Group 1 foods with added ingredients like salt, sugar, or oil for preservation or flavor.
Group 4: Ultra-processed foods (e.g., sweetened yogurts, breakfast cereals, pre-prepared meals). These contain many ingredients, often including additives and substances not typically used in home kitchens.

2. How do ultra-processed foods affect human health, according to recent studies?

A 2024 review of 45 studies involving nearly 10 million participants linked higher consumption of UPFs to a higher risk of dying from any cause and ties to 32 health conditions, including heart disease, mental health disorders, type 2 diabetes, and cancers. The Yale Medicine article notes that UPFs may replace more nutritious foods, expose individuals to unhealthy additives, increase the risk of chronic inflammatory diseases, and contain contaminants from packaging materials. The UPF group in a 2019 study consumed 500 more calories per day than those on the unprocessed diet and gained an average of two pounds during the two-week study period.

3. How can I identify ultra-processed foods in the grocery store?

One practical way to identify UPFs is to check the ingredient list for items rarely used in home kitchens, such as high-fructose corn syrup, hydrogenated oils, and hydrolyzed proteins. Also, look for additives like flavors, flavor enhancers, colors, emulsifiers, and preservatives. Dr. Imaeda at Yale Medicine suggests that if a package has many ingredients and you can't identify some of them, it's probably best to avoid it.

4. Why is dry kibble considered a potentially unhealthy option for dogs?

Dry kibble, the primary diet for 80-85% of dogs, is often considered ultra-processed due to several factors:

High-temperature processing: Extrusion destroys heat-sensitive nutrients, requiring synthetic supplementation.
Low-quality ingredients: Use of meat meals, by-products, and fillers like corn, wheat, or soy.
High carbohydrate content: Kibble often contains 40-60% carbohydrates, contributing to obesity and insulin resistance.
Synthetic additives and preservatives: Use of artificial flavors, colors, and preservatives like BHA, BHT, and ethoxyquin.
Lack of moisture: Low moisture content (around 10%) can contribute to chronic dehydration.
Potential contaminants: Risk of mycotoxins, heavy metals, and even euthanasia drugs in some kibble.

5. What are some less processed alternatives to kibble for dogs, and what are their pros and cons?

Several less processed alternatives to kibble include:

Freeze-Dried Raw Food: Minimal processing, high in protein and nutrients, convenient, but expensive and requires rehydration.
Air-Dried or Dehydrated Raw Food: Retains more nutrients than kibble, higher meat content, convenient, but pricey and may contain fillers.
Gently Cooked Fresh Food: Closest to home-cooked, no artificial additives, easy to digest, but requires refrigeration/freezing and is more expensive than kibble.
Fresh or Frozen Raw Food: Most natural diet, improves coat health and digestion, no synthetic additives, but requires freezer space and can be expensive.
High-Quality, Low-Processed Kibble Alternatives: Less processed than standard kibble, more bioavailable nutrients, easier transition, but still processed and may contain fillers.

6. What are the key components of a balanced home-cooked diet for dogs, and what foods should be avoided?

A balanced home-cooked diet for dogs should include:

Protein (40-50%): Lean meats, organ meats, eggs, fish.
Healthy Fats (10-20%): Fish oil, coconut oil, flaxseed oil, chicken fat.
Carbohydrates & Fiber (20-30%): Sweet potatoes, pumpkin, carrots, peas, quinoa, brown rice.
Calcium & Phosphorus Balance: Crushed eggshells, plain yogurt, bone meal.
Essential Vitamins & Minerals: Leafy greens, berries, and supplements if needed.

Foods to avoid include onions, garlic, grapes, raisins, chocolate, xylitol, avocado, cooked bones, excessive salt, and artificial additives.

7. How can I determine the appropriate portion sizes and caloric intake for my dog when feeding a home-cooked diet?

Daily caloric needs vary based on the dog's weight, age, breed, and activity level. The provided meal plans offer examples for different dog sizes and activity levels. Adjust portion sizes based on your dog's weight maintenance (increase if losing weight, decrease if gaining). Consulting with a veterinarian or veterinary nutritionist is recommended to determine the most appropriate caloric intake and macronutrient ratios for your dog.

8. What are some example meal plans for dogs of different sizes and activity levels using home-cooked food?

The excerpts provide five-day meal plans for:

A 50-pound, highly active, one-year-old Irish Setter: Around 1,400-1,600 kcal per day. High-quality protein sources, healthy fats, fiber, and essential vitamins/minerals to support energy levels and muscle maintenance.
A five-year-old toy breed dog (8-12 lbs) with low to medium activity: Around 250-350 kcal per day. Nutrient-rich ingredients in appropriate portion sizes.
An adult large breed dog (70-100 lbs) with low to medium activity: Around 1,500-2,000 kcal per day. Balanced mix of protein, healthy fats, fiber, and essential nutrients while keeping calories in check to maintain a healthy weight.

These plans include varied protein sources, vegetables, grains, and healthy fats, and may include supplements like fish oil or probiotics as needed.

10. Post-Episode Fact Check

The podcast presents a mix of factual information and opinions about dog nutrition. Here's an assessment of key claims:

ACCURATE CLAIMS:

- Kibble typically contains around 10% moisture while raw/fresh food has about 70% moisture

- Commercial kibble undergoes high-temperature extrusion processing

- The pet food industry adds synthetic vitamins and minerals to kibble after processing

- Many kibble brands contain fillers like corn, wheat, and soy

- Some preservatives mentioned (BHA, BHT, ethoxyquin) have been questioned for safety

- Dogs evolved primarily as carnivores with different nutritional needs than humans

- Calcium and phosphorus balance is important for canine bone health

PARTIALLY ACCURATE/NUANCED CLAIMS:

- The comparison between ultra-processed human foods and kibble has some scientific basis, but the direct health implications for dogs aren't as thoroughly researched as suggested

- The podcast presents a somewhat one-sided view of kibble, downplaying that many dogs live long, healthy lives on quality kibble diets

- The connection between kibble and specific health issues (kidney problems, allergies, etc.) is suggested but not definitively proven in veterinary research

- Raw diets do carry some bacterial contamination risks, which the podcast acknowledges but perhaps minimizes

MISSING CONTEXT:

- The podcast doesn't adequately address that the veterinary community has varying perspectives on optimal dog nutrition

- Many veterinary nutritionists still recommend quality kibble as a balanced option

- Home-prepared diets carry significant risks of nutritional imbalance without proper guidance

- The podcast doesn't mention that AAFCO feeding trials (not just ingredient formulation) provide some quality assurance for commercial foods

- The role of breed, age, and individual health conditions in determining appropriate diets isn't thoroughly discussed

CONCLUSION:

While the podcast provides valuable information about potential concerns with kibble and alternatives worth considering, listeners should consult with experts, particularly those with nutrition training, before making major dietary changes for their pets. The ideal diet varies based on the individual dog's needs, lifestyle, and health status.
