We talk a lot about kibble and the dangers associated with it. Often I get the question, “What about canned dog food? Is it better than kibble?” Here’s the issue with canned dog food…often the cans are lined with bisphenol A (BPA). As consumers, we tend to think about these things for ourselves and our families, but what about our furry family members? BPA can decrease methylation, which is an important epigenetic signaling tool for normal gene expression and a biochemical process found in every cell of the body.
BPA has also been linked to heart disease, including athersclerosis, angina, hypertension, peripheral arterial disease, arrhythmias, etc. It creates hormone imbalance and causes male reproductive dysfunction. It’s considered a “xenoestrogen” which means it attaches to estrogen receptor sites and doesn’t allow natural estrogens to do their job. This is important for men, women, children, and animals alike. It also affects brain function, can cause asthma, and can create changes in the gut microbiome.
Even companies that claim their cans are BPA-free, they may actually be using close chemical relatives such as bisphenol A diglycidyl ether (BADGE), or bidphenol sulfonate (bisphenol S) – both just as dangerous as BPA. I recently saw an article that stated that in just 2 weeks of feeding canned dog food, BPA levels tripled.
Even the the moisture content is better in canned food than kibble (which is important), it is still processed at such high heat levels that most nutrients are lacking. Then nutrients are added back in. Usually these nutrients are cheap, synthetic forms that have the potential of causing damage as well. Remember, balanced does not mean optimal. don’t let marketing fool you – and this includes the prescription foods at your vet clinic.
Food is not people food -it’s food. It’s intended for all living things and necessary for optimal health and longevity. The best thing we can do is make real food for our furry family members or purchase pre-made real food. We want to keep them around as long as possible!
