Grain free diets
Grain free diets have become all the rage in the last few years. I suspect this has stemmed from greater recognition of gluten sensitivity in humans. Most pet food companies have jumped on the band wagon following the marketing success of grain free human diets. The truth of the matter is that there are no dog or cat studies showing a health benefit to grain free foods. A myth has been perpetuated that grains are unhealthy. In fact, whole grains contribute vitamins, minerals and essential fatty acids and are highly digestible by dogs and cats. Allergies to grains are actually very rare, and only the Irish Setter breed has been demonstrated to have a gluten sensitivity. Many grain free diets substitute potatoes and tapioca, which have less protein, more sugar, and less fiber. And typically these come at a higher cost.
Animal by-products
In addition to grain, animal by-products have become “dirty words” on the ingredient list. Although not necessarily appealing to humans (particularly in the USA), the definition of a by-product in pet food is a part of the animal that is not skeletal muscle. This includes organ meats and intestines (not intestinal contents). AAFCO specifically excludes hair, hooves, horns, hide, manure, etc… as acceptable by-products. So in reality, by-products are perfectly healthy and full of nutrients. And you can be sure that a wild wolf or mountain lion is eating “by-products” in nature.
Raw diets
Raw diets are another popular option on the market today. Studies have shown that 20-35% of raw poultry and 80% of raw food dog diets tested contained Salmonella. This poses a health risk for your pet, but also for humans. This is especially true for children or immunocompromised adults, whether exposed to the raw food directly, or the feces of the pet eating the raw food. Additionally, there is increased risk of other bacterial infections and parasitic diseases when feeding raw diets. And the bottom line is there is no reason to believe raw food is healthier than cooked food.
