| Re: Question on Protein Grains are carbohydrates (there are three components to all food resources...protein, fat, carbs). Carbs are broken down into simple sugars after they are ingested. These simple sugars are what fuels the brain and muscles. Whatever sugars are not utilized by the body within a few hours after ingestion are converted to fat for storage. Thus, we know that high carb (sugar) diets results in high lipid (fat) when we check with blood tests. If the dog needs an energy source before his next meal, the fat (previously carbs) can be re-converted to sugar to fuel the brain and muscles. However, most dogs do not have that need. So the fat remains stored as fat.
Protein is used by the body as building blocks for cell growth and replacement. Excess is excreted by the kidneys.
I have one dog that gained a large amount of weight in a short time. I took her to the vet for a thyroid test thinking age had caused a hormonal imbalance. Her thyroid test was normal. We switched her food from kibble (it was 60% carbs) to a raw diet of only meat (with included fat) and bone. She lost the weight within 6 months.
We continue to feed a raw diet to all of our dogs. In the process we also discovered that the previously mentioned obese dog stopped licking her feet raw. The vet determined that she probably has a grain intolerance as well. There are no studies that I know of showing that dogs need grains, or a minimum level of carbs in the diet either. Our dogs have done just fine (had blood work checked to prove it to myself after 18 months on raw) with just protein, fat, and rare carbohydrate of any kind in the diet. We have not fed any grain in over three years now.
So basically, carbs are a source of instant energy. It seems to me that the high carb foods should be listed as "working dog" food then. Protein is also good for high energy, working dogs...giving them the ability to increase muscle as needed for activity level. However, in the case of proteins, the excess is eliminated through the kidneys (would not feed a high protein diet to a dog with poor kidney function, but it does not CAUSE kidney problems in healthy dogs). Excess carbs, on the other hand, are stored as fat. |
