H. pylori is an S-shaped bacterium, 0.5 X 5 μm in length, with a tuft of 5 to 7 polar sheathed flagella in one end. The cell is a non-spore-forming, gram-negative bacterium consisting outer and inner membranes that are separated by the periplasm [1, 3]; its morphology is similar to C. jejuni [6].

This acid solution is to simulate the acidity inside a cat’s stomach. Using a measuring cylinder, pour 300ml of the acid solution into each of the 4 beakers. cat food normally contains about 40% carbohydrates. Carbohydrates hold the crunchy kibble pieces together. The kibble helps reduce the build up of tartar and plaque in the felines’ teeth.

So this is why feeding a dog raw is so much better than a diet of processed food high in carbohydrates. Processing will have destroyed any food based enzymes and the dog can’t break down complex carbohydrates (such as starch) into glucose. The adverse effect on stomach acidity also reduces its ability to destroy pathogens.

As the meal is digested, more gastric acid is produced as necessary. What we do know based on current research is that dogs fed dry food have highly acidic gastric pH values, and that a dog’s digestive system is well equipped with a complex network of hormones and enzymes that regulate the production of gastric acid.

The first bags of commercial pet food entered the market about a hundred years ago. From a historical perspective, processed dog and cat food is a relatively new phenomenon. The bottom line is potentially harmful bacteria resides in your pet’s GI tract whether you feed raw foods or the processed stuff. Dogs and cats are built to handle bacterial loads with highly acidic stomachs and produce tremendous amounts of anti-parasitic and anti-pathogenic bile. occurs when there is an increase in the levels of acid in the blood, which ultimately accumulates to abnormal levels in the body, causing various problems.

pylori pathogenesis; it creates a pH-neutral microenvironment around the bacteria which is necessary for survival in the acidic stomach, pH 1.0-2.0. H. pylori grows best at neutral pH and fails to survive at a pH below 4.0 or above 8.2 in the absence of urea.

So the natural ‘wild” diet of dogs and cats has evolved a gastric environment that favours the breakdown of raw meats, raw bones, and a pH that kills potentially harmful bacteria – consistent with the requirements of carnivores, and in particular, the scavenging nature of dogs. The highly acidic environment in the stomach lumen causes proteins from food to lose their characteristic folded structure (or denature). This exposes the protein’s peptide bonds. The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.

Non-spayed, middle aged female pets can develop a uterine infection called pyometra. Pyometra occurs within 2 months after a heat cycle and often results in discharge of pus from the vagina. The pet may frequently lick the vagina so discharge may not be seen. Dogs develop pyometra more often than cats.

This value is substantially lower than the theoretical acceptable chloride content for dogs shown above. Nevertheless, these cats received the increased chloride mainly as the ammonium salt, which produces a greater degree of metabolic acidosis than occurs with calcium or sodium salts. This may have resulted in the adverse effects on calcium and potassium balances. It is clear, therefore, that the toxicity of excessive chloride in the diet depends crucially on the mineral salt that is delivering the increased amount. If the dietary chloride is mainly in the form of neutral salts (such as sodium), then the acceptable value for the dog will also be applicable to cats, since the acceptable dietary sodium content for cats is similar to that for dogs.

A. The Raw Meals we stock from Natures Menu are ready-made raw meals for cats and dogs that comply with the guidelines for a complete and balanced pet food. We can also order in any of the Natures Menu just minces though for you to create raw meals for your pet in your own kitchen. When meat is rotted in certain conditions where no bad bacteria can get established, it can be, and in some cultures is consumed by humans. Some researchers suggest there are about 120 thousand types of good bacteria and only about 4 thousand bad ones.

The acidic chyme (food mixed with gastric juices) leaving the stomach is the trigger for the next stage of digestion in the small intestine. The acidity encourages the flow of bile and the flow of pancreatic enzymes necessary to continue the digestive process. If the stomach contents are not sitting at a pH of around 1-2, then digestion is impaired throughout the rest of the digestive tract as well. (with special thanks to June Perbohner, for her incredible dedication to finding and preserving copies of hundreds of research papers concerning stomach acid and disease from the 1800’s onwards) The book was written to help people dealing with Heartburn, indigestion, reflux and GERD. In the absence of food the resting pH in the stomach is around 1-3.

As a result, in addition to moving food through the canal, the stomach can vigorously churn food, mechanically breaking it down into smaller particles. Popular culture tends to refer to the stomach as the location where all digestion takes place. Of course, this is not true. An important function of the stomach is to serve as a temporary holding chamber.

In Zollinger-Ellison syndrome and hypercalcemia, there are increased gastrin levels, leading to excess gastric acid production, which can cause gastric ulcers. In such conditions, there is greater risk of infections of the digestive tract (such as infection with Vibrio or Helicobacter bacteria). If you are transitioning your kitty to a raw cat food diet, you may be feeding a combination for a short period of time.

There are many ways to feed raw foods cheaply and effectively and I feel that raw feeding is incredibly accessible if owners are given sound advice re sourcing product themselves. But the talking point people use to claim that mixing is dangerous is that the stomach acid isn’t acidic enough to digest protein properly, or isn’t acidic enough to be an environment that isn’t friendly to pathogenic bacteria. This is what isn’t true, and why I broke down the process of digestion in the stomach with an emphasis on gastric pH. You can see by following along the gastric digestion process in the article that even when a dog eats a lower protein meal, gastric acid is still produced regardless of the content of the meal – even BEFORE the meal is eaten.

So the natural ‘wild” diet of dogs an cats has evolved a gastric environment that favours the breakdown of raw meats, raw bones, and a PH that kills potentially harmful bacteria – consistent with the requirements of carnivores, and in particular, the scavenging nature of dogs. The gastric acidity (gastric pH) of the stomach of a dog or cat eating a diet predominantly made up of raw meat is very low (very acidic), with a pH of 2 or lower. Note that pH is measured on a logarithmic scale ie a pH of 1 is ten times as acidic as a pH of 2. This highly acidic environment favours the breakdown of raw meats, and raw bones, into soft digestible material. The low pH also is highly effective at killing bacteria, particularly potentially pathogenic bacteria like salmonella, campylobacter and E Coli.
