Key Highlights
- Kale is rich in antioxidants, Vitamin C, and K; it can help reduce the risk of chronic disease and support cancer prevention.
- It is an excellent source of fiber, which helps maintain a healthy microbiome.
- Pets with a history of urinary stones, crystals, or uncontrolled thyroid disease should not eat kale.
Introduction
Kale, a nutrient-dense leafy green belonging to the Brassica family (which includes broccoli, cabbage, and Brussels sprouts), has gained popularity as a superfood in the human diet. I routinely get questions and comments that it is potentially dangerous. Let's explore and debunk this myth now!
Health Benefits
This superfood is packed with essential nutrients, antioxidants, and calcium that can benefit both dogs and cats in moderation.
- Rich in vitamin C, K, E, selenium, and beta-carotene, all supporting immune system function.
- Excellent source of plant-based calcium.
- Contains antioxidants that mop up free radicals, thus decreasing oxidative stress.
- Contains compounds that may help protect against cancer.
- It is low in calories but high in fiber, promoting satiety and digestive health.
Rich in antioxidants, kale helps fight free radicals, potentially reducing the risk of chronic diseases and supporting cancer prevention.
Addressing the Safety Concerns:
Contrary to some misconceptions, kale is generally safe for dogs and cats when fed in moderation. While it's true that kale can cause issues in ruminants (cows, goats, sheep) such as bloat and anemia, our domestic pets have different digestive systems and can typically handle kale without problems.
How Much Kale Is Too Much?
When adding kale to your cat or dog food, you should do it in moderation. Start by giving small amounts of kale to see how your dog reacts. Large quantities of kale can upset your dog's stomach, which can cause adverse side effects like gas, bloating, and diarrhea.
A good guide is to keep kale snacks to no more than 10% of your dog's daily calorie intake. For treats now and then, even smaller pieces are better.
Keep in mind that every dog is different. An amount that is fine for one dog might be too much for another. So, always be safe and check with your vet to find the right serving size.
Who Should Avoid Kale?
While kale is generally safe, there are a few points to keep in mind:
- Moderation is key: Like any dietary addition, kale should not be fed in excess. Treats and add-ins should not exceed ten percent of the diet.
- Potential digestive sensitivity: Some dogs or cats may experience mild gastrointestinal discomfort, but this is rare.
- Pets with uncontrolled thyroid issues should not consume a large amount of any cruciferous vegetable.
- Calcium Oxalate concerns: Pets with a history of oxalate stones or crystals should avoid kale and other oxalate-rich foods.
However, for most healthy pets with no history of oxalate crystals or stones, the oxalate content in kale is not a significant concern when consumed in moderation.
Practical Tips
Start with a few tablespoons of finely diced or lightly steamed kale. You can slowly add more over time. I rotate it in with other greens such as broccoli and spinach.
Choose organic kale if you can. Wash it well to eliminate any pesticides or other harmful residues. Wash it well to remove dirt and pesticides. Choosing organic kale can help lower pesticide exposure even more.
Next, remember the goitrogenic properties of raw cruciferous vegetables, like kale. Lightly steaming or blanching the kale can reduce these compounds in pets with thyroid issues. Avoid feeding large amounts to pets with thyroid issues.
Finally, pay attention to the tough kale stems. Some dogs might eat them just fine, but removing the stems can improve digestibility. This can also cut down the chances of stomach upset.
Conclusion
In conclusion, kale can be a healthy part of your pet's diet if you introduce it carefully and prepare it right. It is essential to know the benefits and risks of feeding kale to your pets before throwing this nutrient-rich baby out with the bathwater!
Frequently Asked Questions
Can kale cause adverse reactions or digestive issues in pets?
Although rare, gastrointestinal discomfort such as vomiting, diarrhea, bloating, and inappetence have been reported. I have never seen this, but anything in excess can become problematic.
How often can I feed my dog or cat kale?
Kale can be added in moderation, but it should not be a regular part of your dog’s diet. Feeding them small quantities of cruciferous veggies once or twice a week is usually safe for healthy dogs as a supplement to their diet. If your dog has health issues, it’s best to ask your vet for advice.
Can pets with a history of oxalate crystals or bladder stones eat kale?
Dogs and cats with a history of oxalate crystals or stones should not eat kale.
Is cooked kale better for pets than raw kale?
Cooked kale is usually easier for dogs to digest than raw kale. Steaming or quickly blanching kale helps make it softer. This improves how well they can digest it and lowers any potential health problems related to goitrogenic effects. Additionally, green beans can be a nutritious alternative to consider.
