When most people think about dog food, they think about protein as fuel: muscles, energy, maybe skin and coat.
But emerging research suggests protein source may also influence something much bigger: how the immune system regulates inflammation.
A newly released study from Innovafeed and Ambiotis adds to a growing body of evidence that insect protein — specifically black soldier fly (BSFL) ingredients — may help support healthy inflammatory responses in dogs.
That matters because chronic inflammation is increasingly linked to many of the issues dog parents struggle with every day:
- itchy skin
- paw licking
- digestive upset
- ear irritation
- joint discomfort
- poor skin barrier function
- recurring sensitivities
And importantly, this new research suggests insect protein may help support inflammation without suppressing normal immune function.
WHAT THE NEW STUDY FOUND
The whitepaper, titled Resolution of Inflammation: Innovative In Vitro Evidence for Functional Pet Nutrition, evaluated how BSFL-derived ingredients affected inflammatory markers in canine immune cells.

Innovafeed & Ambiotis whitepaper on inflammation resolution
Researchers observed two especially important effects:
- a reduction in TNF-α, a major pro-inflammatory cytokine
- an increase in IL-10, an anti-inflammatory cytokine involved in resolving inflammation
According to the researchers, this “dual modulation” may help support the body’s natural process of resolving inflammation rather than simply shutting immune activity down altogether.
That distinction matters.
Some approaches reduce inflammation broadly. But the immune system still needs to remain functional and responsive. The goal is balance — not suppression.
The study authors describe this as supporting the “resolution phase” of inflammation: the process where the body returns tissues back to normal equilibrium after an immune response.
WHY THIS MATTERS FOR DOGS
Inflammation itself is not bad.
It’s a necessary biological process that helps the body respond to injury, infection, and environmental stressors.
The problem comes when inflammation becomes chronic or dysregulated.
In dogs, that can show up as:
- recurring digestive issues
- chronic itching
- hot spots
- red ears
- excessive shedding
- poor coat quality
- ongoing sensitivity reactions
Many dogs today are repeatedly exposed to the same conventional proteins — chicken, beef, dairy, lamb, fish — over and over again.
For some dogs, constant exposure may contribute to food sensitivities and ongoing immune activation.
That’s one reason novel proteins can be helpful.
And insect protein is one of the most novel proteins available to dogs today.
INSECT PROTEIN IS MORE THAN JUST “NOVEL”
The conversation around insect protein often starts with sustainability.
But increasingly, the science is pointing toward functional health benefits too.
Black soldier fly protein naturally contains bioactive compounds including:
- antimicrobial peptides (AMPs)
- lauric acid and other medium-chain fatty acids
- chitin and chitosan compounds
- highly digestible amino acids
Researchers are actively studying how these compounds may interact with:
- the gut microbiome
- skin barrier health
- immune signaling
- oral health
- inflammatory pathways
This is one reason insect protein keeps appearing in new pet nutrition research.
The ingredients aren’t simply replacing traditional meat proteins. They may have distinct biological effects of their own.
THE GUT-IMMUNE CONNECTION
A large portion of the immune system is connected to the gut.
When the gut microbiome becomes imbalanced, immune signaling can also become dysregulated.
This is one reason digestive symptoms and skin symptoms often appear together in dogs.
Previous research on insect protein has already shown potential benefits related to:
- digestibility
- microbiome diversity
- stool quality
- skin barrier function
This new study adds another piece to the puzzle by examining inflammatory signaling itself.
Taken together, the evidence is starting to suggest that insect protein may support dogs through multiple interconnected systems:
- gut health
- immune regulation
- skin health
- oral health
- inflammatory balance
That systems-level effect is important because most chronic issues in dogs are not isolated problems.
They’re connected.
WHAT MAKES THIS STUDY INTERESTING
A few things stand out.
1. The mechanism matters
The study did not simply observe symptom improvement.
It examined cytokine signaling — the chemical messengers involved in inflammation regulation.
That gives researchers a more mechanistic understanding of why insect ingredients may help.
2. It focused on inflammation resolution
Many anti-inflammatory interventions work by suppressing immune activity broadly.
This study instead points toward supporting the body’s own resolution pathways.
That’s a more nuanced and potentially important distinction.
3. It adds to a growing evidence base
No single study proves everything.
But this research aligns with other published findings around insect protein and:
- skin barrier improvement
- oral microbiome support
- digestibility
- microbiome modulation
- allergy support
The evidence base is still developing, but the pattern is becoming harder to ignore.
WHERE MORE RESEARCH IS STILL NEEDED
There are still important limitations.
This was an in vitro study, meaning researchers evaluated immune cell responses in a controlled laboratory setting rather than through long-term feeding trials in dogs.
That means:
- the findings are promising
- the biological mechanism appears plausible
- but additional clinical studies are still needed
Questions that future research should help answer include:
- Which dogs benefit most?
- What dosage levels matter?
- How long do effects take?
- Which compounds are driving the response?
- How do outcomes compare against other novel proteins?
This is an area where the science is moving quickly.
WHY JIMINY’S HAS BEEN FOCUSED ON THIS FOR YEARS
At Jiminy’s, we’ve long believed insect protein offers more than sustainability benefits alone.
We’ve seen firsthand how many dogs struggling with itching, digestive issues, or food sensitivities improve when switched to insect-based diets.
What’s encouraging is that the research is increasingly catching up to what many pet parents and veterinarians have already observed in real life.
The future of pet food may not just be about avoiding problematic ingredients.
It may be about choosing ingredients that actively support healthier biological function.
And insect protein is looking more and more like one of those ingredients.
FAQS
CAN INSECT PROTEIN HELP DOGS WITH ALLERGIES?
Potentially, yes.
Because insect protein is a novel protein for most dogs, the immune system is less likely to recognize it as a previously encountered allergen. Emerging research also suggests insect ingredients may help support healthy inflammatory responses.
DOES THIS STUDY PROVE INSECT PROTEIN TREATS INFLAMMATION?
No.
This was an in vitro laboratory study, not a clinical treatment trial in dogs. The findings are promising and biologically relevant, but additional feeding studies are still needed.
WHAT IS TNF-α?
TNF-α (Tumor Necrosis Factor alpha) is a pro-inflammatory cytokine involved in immune signaling. Elevated TNF-α is associated with inflammatory processes in both humans and animals.
WHAT IS IL-10?
IL-10 is an anti-inflammatory cytokine that helps regulate immune responses and supports the resolution of inflammation.
WHY IS “RESOLUTION OF INFLAMMATION” IMPORTANT?
Healthy immune systems need to activate inflammation when necessary — and then properly turn it off afterward.
Failure to resolve inflammation appropriately may contribute to chronic inflammatory conditions.
IS INSECT PROTEIN SAFE FOR DOGS?
Yes. Black soldier fly larvae and cricket protein have been approved for use in dog food and are highly digestible complete proteins containing all essential amino acids.
IS INSECT PROTEIN GOOD FOR THE GUT MICROBIOME?
Emerging research suggests insect protein may positively influence microbiome composition and digestive health, though more long-term studies are still underway.
