Nutrition

The most important thing you can do for your pet’s health is to feed an appropriate diet. Proper nutrition provides the building blocks of good health. Most dry commercial pet foods are processed at very high temperatures that destroy a good deal of the nutritional content of the ingredients. Vitamins and minerals are then sprayed back on the food along with flavoring to get your pet to eat it. The commercial pet food industry, through creative advertising, would like you to believe that these diets are the best you can do for your pet. This could not be further from the truth.  In fact, I would put these processed diets at the bottom of the food chain of health for your pet.  Fresh food is essential for the health of your pet, and without it, the health of your pet will suffer. (see my article on Feeding Fresh Food.)

In my 30+ years of experience as a veterinarian, I have recommended many different types of diets.
There is now no doubt in my mind that pets are healthier when fed fresh, whole foods in their diets. The freshest, most natural diet to feed a dog or cat is a raw, meat- based diet.

Here are some healthy tips for your pet’s diet:

  1. Feed the freshest diet possible, ideally a balanced raw diet. All dry and canned foods are processed at high temperatures which not only destroys some nutrients, but damages others making them toxic.
  2. Home-prepared meals are challenging to prepare properly.  It is typically more cost effective and better nutrition for your pet to buy an appropriately balanced and well sourced commercial raw diet.
  3. Nose to tail nutrition helps complete the diet.  Most meat based diets focus on the muscle portion, which is actually the least nutritious part of the animal.  Organ meats such as liver, kidney, heart, lung, brain, and others are incredibly rich in vitamins and minerals.  Feeding an adequate amount of these in the diet is an ideal way to provide complete nutrition in a whole food formulation.
  4. Be sure that all ingredients are well-sourced – organic, pasture-raised, and fed an appropriate diet.  Ruminants such as cows and sheep are not meant to eat corn and other grains.  In fact, they are toxic to them, and fed in large amounts only to add weight before slaughter.
  5. For Cancer patients, a ketogenic diet can provide additional benefits. What is a ketogenic diet, and what is its role in treating and preventing cancer?  Basically, it is a diet that trains the body to burn fat instead of carbohydrates.  Why is this important?  There is a basic principle that was discovered by Dr Otto Warberg:  “Cancer, above all other diseases, has countless secondary causes. But, even for cancer, there is only one prime cause. Summarized in a few words, the prime cause of cancer is the replacement of the respiration of oxygen in normal body cells by a fermentation of sugar. All normal body cells meet their energy needs by respiration of oxygen, whereas cancer cells meet their energy needs in great part by fermentation. All normal body cells are thus obligate aerobes, whereas all cancer cells are partial anaerobes. From the standpoint of the physics and chemistry of life this difference between normal and cancer cells is so great that one can scarcely picture a greater difference. Oxygen gas, the donor of energy in plants and animals is dethroned in the cancer cells and replaced by an energy yielding reaction of the lowest living forms, namely, a fermentation of glucose.”Cancer cells require sugar to grow and thrive, while normal, healthy cells can switch to a fat-burning metabolism.  Therefore, by decreasing the intake of simple sugars and giving the body ample fat to use as a fuel, the cancer cells are essentially starved.It is still necessary for your pet to consume a balanced diet, complete with all the essential vitamins and minerals.  Here’s the bonus – well-sourced fats contain an abundance of nutritional value.  The sourcing here, is the key though.  Only animal fats that are pasture – raised and fed a species appropriate diet free of chemical additives will provide these nutritional benefits.  Saturated animal fat has gotten a bad reputation for causing a number of health problems including cardiovascular disease in people and pancreatitis in dogs and cats.  Fats from factory-farmed animals that are raised in crowded, stressful conditions and fed chemical laden, genetically modified grains will most definitely cause disease.So how do we facilitate the switch to a fat-burning metabolism?  There are two primary fuels that the cells in the body can utilize for energy, glucose and fat.  The body will use whichever fuel is most abundant.  Any diet that is high in carbohydrates, which for pets includes grains, starchy vegetables such as potatoes and squash, legumes such as beans, peas, and lentils will keep the body in a sugar-burning state.  In addition, any food that is highly processed will alter the metabolism

    The energy center for most cells in the body is a tiny organelle called mitochondria that produce energy in the form of adenosine triphosphate (ATP) by combining the available fuel source with the oxygen in the blood.  Fat is a more stable form of energy that does not create the effects of blood glucose swings such as weakness and light-headedness.  Once the body changes to a fat burning metabolism, it will also use up available fat stores if ingested fat is not available.  This means that a lean body mass is attained without calorie restriction.  The body will be able to operate on a much lower glucose levels without any side effects, and feel satiated by the increased fat in the diet

    Training the body to burn fat is possible only when blood glucose and insulin levels drop. This is accomplished by reducing the intake of sugars and starches, which causes the body to start burning fat, either from the diet, or from that stored in the body.  The fat is then broken down into free fatty acids, which are then converted into ketones in the liver.  There are three types of ketones: Beta-hyrdroxybutyrate, Acetoacetate, and Acetone.  BOHB is a super fuel for the body, and is the most efficient energy producing ketone.  There is no dietary requirement for carbohydrate.

    The best way to know if the body is burning ketones instead of glucose is to measure the blood level of ketones and glucose at the same time.  This is a simple process that can be done in the clinic, or you can purchase a meter and measure the levels at home.  There are some cells in the body that have few or no mitochondria and will need to burn glucose instead of ketones. These include the renal medulla (a part of the kidney), white blood cells, and testes. Cells with no mitochondria include red blood cells, and the retina, cornea and lens of the eye. The amount of glucose required in these cells is very small.  The body can manufacture enough glucose through the process of glycogenolysis, or breaking down liver glycogen to form glucose. In addition, gluconeogenesis, or the process of manufacturing glucose in the body and is very efficient and able to make enough to meet cellular demands.  There is no need for dietary glucose to meet the needs of these cells.

    The health benefits of a ketogenic diet are numerous, and include treating, and in some cases, resolving conditions such as diabetes, seizures, cancer, auto-immune disease, hormonal imbalances, and weight issues.  In addition, a ketogenic diet helps support the immune system to prevent infections and helps the body to detox.

    Additionally, there are a number of very important vitamins that are only found in well-sourced fat that are essential for optimal health, and responsible for some of the benefits listed above. (see The Skinny on Fat handout for more details)

    There really is no reason to NOT try this diet for your pet.  Getting started is not difficult, it is just new information that you are not accustomed to.  We have very simple, yet effective dietary guidelines, and we will assist you in measuring your pet’s blood to be sure that we are on the right track.

     If you are hesitant to make this change, or if your pet has particular health concerns, I am available to help with a private consultation. Please see my Consult page for more information. The diet options above can be used with any type of health condition, but medical guidance is recommended.
