BHA is a controversial preservative found in many dog foods. But it's been linked to cancer & reproductive disorders... so is it really safe...? 🤔
US government regulations allow BHA in dog food, considering it safe in low doses. But BHA has been found to produce malignant tumors in lab animals & the State of California includes it on its “Chemicals Known… to Cause Cancer or Reproductive Toxicity” report.
So too, the EU considers BHA a ‘hormone disruptor‘… because studies have shown it can damage the s***m quality of male rats and the s*x organs of females. Indeed, BHA is banned from use in certain EU food products for this reason 👀
And dogs may be at greater risk. This is because, unlike humans, who vary their diets with each meal, dogs are typically fed the same food continuously. Day after day. For a lifetime.
It’s that cumulative exposure to a risky chemical (like BHA) that can magnify its effect on your dog's body.
So why take the risk? 🤷♀️
Dog food companies include BHA in recipes because it extends the shelf life of a dog food longer than natural preservatives. It does a great job of stopping fat going rancid. Which can make the food more profitable for the pet food company.
But does it make the food more dangerous for our dogs?
By contrast, many pet foods are preserved with super-safe natural preservatives like…
✔️ Ascorbic acid (vitamin C)
✔️ Mixed tocopherols (vitamin E)
Look. Here’s the point. Considering all the dangerous health issues linked to BHA, it seems logical to avoid dog foods that contain it. After all there are many quality dog foods that don't contain this controversial ingredient.
As our expert pet nutritionist, Laura Ward, says "I prefer to avoid BHA. It does a great job as an antioxidant - it certainly works to delay foods becoming rancid. But, since there are other options now, such as antioxidants which are based on vitamin E, I don't see any need to use artificial antioxidants for which studies have shown there is the potential for negative health effects."
Our best advice is to check your dog food labels. Look for the “fat” ingredient, followed by the words “preserved with BHA. And avoid where possible.
