Brassicas/Cruciferous Veg for Dogs. 🐶🥦
Brassica refer to a family of vegetables including Cauliflower, Brussels Sprouts, Cabbage and Kale. These are often avoided in dogs, but do they need to be?
The Brassicas family has a bad rep because it can cause Gas and Bloating if not prepared in the right way.
Preparation, just like with any veg that we feed our Dogs, can be as simple as just freezing and thawing, or lightly steaming, just to break down the cellulose walls and enable efficient digestion.
Brassicas have a great range of vitamins (C, K, A, E), Minerals (Potassium, Iron, Calcium, Zinc, Phosphorus, Magnesium, Manganese), and also contain sulphoraphane - great for removing AGE's (see first comment), as well as other compounds that have antioxidant and anti-cancer properties.
HOWEVER, they do also contain glucosinolates, which convert into Goitrogenic compounds. These compounds, when fed to particularly sensitive Dogs, those with existing Thyroid issues, or on diets deficient in Iodine can impact thyroid function negatively.
The Gas and Bloating is caused by a complex sugar called Raffinose that isn't able to be properly digested, this ferments and, alongside fibre, cause gases like Methane, Sulphur, Hydrogen and Carbon Dioxide. This can be avoided by adding fresh Parsley to your Pet's bowl. Parsley contains the Carminative compounds Apiol and Myristicin. These work to improve digestion by relaxing the smooth muscles in the intestinal walls, promoting the efficient movement of food through the intestines, preventing undigested food fermenting and causing gas buildup. It also has Diuretic properties, preventing bloat from water retention.
Due to the gas and bloating risk, it is often advised to not feed large breed or deep chested dogs any of these Vegetables. However, the addition of Parsley removes much of the risk associated with bloat and Gastric Torsion.
In summary, there is plenty of negative hype surrounding the use of using Brassicas in Dog's diets, but when used properly, as a small part of their 4-5% fruit and veg portion, there is minimal risk and plenty of benefit to be had!
