We have all heard about sugar making kids hyperactive, but did you know that it is a myth that has been debunked? The truth is, blood sugar level in the body (including our dog's body) is tightly regulated by a hormone called insulin. When the body does not produce enough insulin or for some reason the insulin function is inhibited, the cells in the body are unable to utilise the sugar for energy. This results in the body starving despite the high availability of sugar in the bloodstream.
Unfortunately, most dogs have a non-curable form of diabetes mellitus where insufficient insulin is produced. However, it's not all doom and gloom. Fortunately, we have management tools like insulin therapy to help manage the condition.
In addition to insulin therapy, managing your pet's diet can also help. The goal is to minimise large spikes in blood sugar levels. This article goes over 4 things you want in choosing a diabetic diet.
Disclaimer: Before making any changes, it is important to first consult your regular veterinarian to avoid destabilising your pet's condition.
Low Glycemic Index
Glycemic index (GI) is a measure of how quickly ingested foods affect blood sugar levels. Low GI foods are broken down slowly resulting in a more gradual rise in blood sugar levels over time.
High Protein
Protein levels can help with maintaining muscle mass, help with controlling blood sugar levels and aid with satiety. When protein is digested, it does not cause as big of a spike in blood sugar levels compared to carbohydrates. Wet foods, generally contain higher protein levels and lower carbohydrate.
Blend of Fibres
Fibre can help with weight management which obesity is often a risk factor in diabetic dogs. It works by keeping your pet full for longer and can also help reduce spikes in blood sugar levels.
Palatability
In diabetic management, consistency is key. It is important to ensure that the diet being fed to your pet is one that will ensure consistent intake.
Commercial diets over home-cooked diets are generally recommended as it takes the work out of ensuring the diet is correctly formulated and consistently the same.
Veterinary diets for diabetic dogs
