Ask a vet: should I be feeding my dog “superfoods”?

There are certain foods that contain compounds that have shown benefit to living systems. The media has coined the phrase “super foods” and there is a lot of talk about them. Restaurant chains are even adding in superfood sections to their menus. These foods are thought to help in the management of certain disease processes like osteoarthritis, cancer and brain aging. Some of these compounds may even have a role in immunity against infectious disease and improving skin and hair coat.

Here is a run down of some things that might be beneficial for your dog.

Flax seed/Omega 3 Fatty Acids

Dogs with osteoarthritis were able to be effectively managed with lower doses of prescription anti-inflammatories when they received concurrent dosing with dietary supplementation with omega-3 fatty acids¹. Flax seeds are a source of omega 3 and while there is proof that omega 3 fatty acids reduce inflammation², there is little guidance about the absorption of these from foods. Omega 3 fatty acids can be found in fish oils and other seeds also. Find a source that is convenient for you and palatable for your dog.

Coconut Oil/Medium Chain Fatty Acids

Coconut has medium chain fatty acids (MCFA) whose properties and metabolism are different from the more dangerous fats of animal origin. Medium chain fatty acids appear to have positive effects rather than harmful ones. ² Not much work has been done on how much coconut oil is most effective, so use common sense and moderation until we know more. Remember, there are calories in oils so account for the additional intake in your dog’s daily allotment to avoid obesity.

Tumeric/Curcumin

Tumeric is a spice that contains curcumin. Curcumin has been shown to have many beneficial effects from anti-viral activity to anti-inflammatory action. ^3,4 Some has suggested that it shows improved cognition and delays brain aging. ⁵ It is readily available and comes in powder form that is easily blended into canine rations. The future may bring more specific recommendations and/or supplements that are proven to be more bioavailable.

Blueberries/antioxidants

Oxidative damage has been linked to many disease conditions and may contribute to the effects of aging. Blueberries are known source of antioxidants ⁷ and may have some anti-viral effects ⁸. Even though we do not know exactly how much blueberry is the best to maximize the positive effects, they are palatable to most dogs and low in calories.

All of the foods and additives above may be a good idea to give your dog, but use moderation and know that we do not have specific guidelines. As we learn more, we will have better defined daily allowances and preparations that maximize oral absorption, but because this is a “can’t hurt, might help” situation, they are worth considering.
