Love this, great information
Many pet food brands highlight blueberries as a source of antioxidants, suggesting health benefits for pets. Blueberries are indeed rich in polyphenols, plant compounds with antioxidant and anti-inflammatory properties that support both human and animal health.
In this study, researchers analyzed 40 popular bags of pet food (18 cat and 22 dog) purchased from four pet stores, Pet Valu, Global Pets, Rens Pet Depot, and Pet Smart, listing blueberries as an ingredient to measure quercetin, free phenolics, and antioxidant-protected phenolics. Overall, cat kibble had lower average levels of quercetin and antioxidant-protected phenolics compared to dog kibble. Free phenolics were minimal to undetectable in all products.
The findings suggest that extruded kibble containing blueberries is unlikely to provide meaningful levels of polyphenols on its own, and therefore may not serve as a reliable antioxidant source for cats and dogs.
Blueberries are one of the ultimate longevity foods, like a suit of armor for your pet.🐾🫐 Rich in prebiotic fiber and powerful polyphenols, they help repair DNA, fight free radicals, slow aging, protect against cell damage, and support the body’s antioxidant defenses making them one of the best anti-aging treats to share straight from your fridge! (opt for spray-free if possible!)
Start with ¼ to ½ tsp per 10lbs of body weight a day.
