Deep dives
Raw Food Diets for Pets
Raw food diets for pets have gained popularity as they are believed to be more nutrient-dense and closer to what ancestral dogs and cats ate. However, experts caution against these diets as they pose risks of bacterial contamination and parasites. The American Veterinary Medical Association actively discourages raw food diets for pets, citing significant risks to the family and other pets. Homemade diets may lack proper nutrients and balance, leading to suboptimal diets for pets. Cooking food increases its digestibility and nutrient availability. While some pet owners may choose raw diets to address food allergies, actual food allergies in pets are rare and should be diagnosed by a veterinarian. The absence of scientific evidence makes it unreasonable to attribute raw food diets to preventing or curing specific diseases like cancer.
The Truth About Grain-Free Pet Food
Grain-free pet foods have gained popularity and are marketed as healthier and more nutritious alternatives. However, there is no scientific evidence that grain-free diets are superior to diets containing grains. The FDA is currently investigating a potential association between grain-free pet foods and dilated cardiomyopathy (DCM) in dogs. While the investigation is ongoing, data collected thus far suggest a potential link. Grain allergies are uncommon in pets, and other causes of dermatologic adverse food reactions should be considered first. Grain-free pet foods often replace grains with alternative carbohydrates like peas, beans, and potatoes. These replacements may lack essential nutrients and can increase the risk of nutritional deficiencies for pets.
The Risks of Vegan and Vegetarian Diets for Pets
Feeding pets vegan or vegetarian diets is a growing trend among some pet owners who are vegan or vegetarian themselves. However, this can pose risks for pets, particularly cats. Cats are obligate carnivores and require certain essential amino acids, like taurine, that are only found in animal-based proteins. Feeding cats vegan or vegetarian diets can lead to taurine deficiency, which can be fatal. Applying human moral standards to the diets of obligate carnivores is not recommended. It's important to feed pets what they need nutritionally rather than imposing human dietary restrictions. For pet owners who prefer not to feed animal products, choosing a pet that does not require them, such as a rodent, may be a more suitable option.
Selecting Pet Food and the Importance of Moderation
When choosing pet food, it is important to prioritize brands regulated by the FDA and those that undergo rigorous quality control measures. Large pet food manufacturers often have robust quality control systems to ensure safety and efficacy. Boutique brands may lack the same level of oversight and testing. However, it is recommended to try different brands and observe how pets respond to them, focusing on factors like coat condition, energy levels, and overall health. Avoid overfeeding pets, as obesity is a significant problem that leads to various health issues. Feeding pets a healthy and moderate amount of suitable pet food is crucial for their well-being and longevity.
On this week's episode of the pod, we kick off the new year with a topic that is near and dear to our hearts-- our pets! (More specifically, fad pet diets.)
We all want what's best for our furry friends, so we dig into the available evidence (or lack thereof) behind several very pup-ular diets including grain-free diets, raw food, vegan and vegetarian diets, human food as treats, and more. We dig into the pet food industry and safety standards for pet foods. We discuss differences in dietary needs for cats versus dogs and how certain diets put them at risk for potentially life-threatening deficiencies and health issues. We were joined by an expert on this topic, a doctor of veterinary medicine, to weigh in. You don't want to miss this!
