As more pet guardians embrace wellness and healthier eating, we have become more aware of what’s on our plates and what’s in our pet’s food bowls. As a result, superfoods have become an essential piece of the puzzle when selecting the best diet for our dogs and cats—but how do we know if a superfood is really ‘super,’ or just marketing fluff?


Superfood Origins

The word ‘superfood’ is defined by Merriam-Webster as: a food (such as salmon, broccoli, or blueberries) that is rich in compounds (such as antioxidants, fiber, or fatty acids) considered beneficial to a person's health.

Perhaps surprisingly, this word originated from a marketing campaign. During the first World War, bananas were promoted as being not only cheap, but nutritious, easily digested and readily available. The popularity of the term soared after being endorsed in medical journals, due to physicians publishing their findings of a banana diet to treat conditions like celiac disease and diabetes. The United Fruit Company promoted these health benefits while the press flaunted headlines about bananas, paving the way for the future of superfoods. (Harvard T.H. Chan School of Public Health, 2021)

Today, a new ‘superfood’ emerges every month and it’s easy to see why when you see the sales associated with foods labelled ‘superfood,’ ‘superfruit’ or ‘supergrain.’ So, how can we trust the superfoods in our pet foods deliver on their promise to be ‘super’?

Animal-Based vs Plant-Based Superfoods

A carnivore’s (cats and dogs) stomach is full of acid. This acid is efficient at uncoiling large protein molecules so the body can absorb the amino acids contained inside. The proper array of amino acids must be absorbed into the liver for additional processing and recognition.

Whether a superfood is meat-based or plant-based makes a difference to determine the impact it will have on your pet’s health and digestive system. Animal-based superfoods (e.g., organs, seafood oils, etc.) are more digestible than plant-based superfoods (e.g., berries, kale, etc.) due to the way the proteins are broken down within your cat or dog’s digestive system.
