When referring to food, bioavailability means the degree to which nutrients in a food source are absorbed and utilised by the body after eating.
Many things can affect the bioavailability of ingredients. Their chemical form (and therefore their quality), interactions with other components of the meal and physiological responses within the body are some of the key factors.
The dog evolved in a time when food was simple relative to today. Ingredients were in their whole-food forms and processing was minimal to non-existent. Dogs’ bodies are therefore equipped to thrive on these simple ingredients. These types of foods are the most highly bioavailable things you can feed to your dog, meaning they will be able to absorb and utilise them most efficiently and produce the least amount of waste (always a bonus 💩).
Look at the ingredients list on your dog’s food. If the list is long and complex, containing chemical names you don’t recognise and reams of nutritional additives, this suggests it has been subjected to ultra-processing, meaning the chemical form of the ingredients will no longer be their optimal, most bioavailable state. If fed over a long period of time, these low-bioavailability ingredients can start to impact your dog’s gut microbiome and unpleasant symptoms may begin to show such as itchiness, hotspots, ear irritation, inflamed a**l glands and frequent upset tummies.
