Gastric Acidity & Mixed Feeding — Raw Essentials

The volume of the stomach increases at meal times and decreases as chyme leaves the stomach and enters the small intestine. The relaxed (empty) stomach has folds of lumen, which expands upon food arrival and almost disappears in a full stomach [11]. Enzymes and acids are secreted in the stomach to break down food molecules, which is stored for gradual energy use.

Therefore, other test panels may also be used along with the blood chemical profile. You will need to give a thorough history of your cat’s health, including a background history of symptoms, and possible incidents that might have precipitated this condition (such as suspected antifreeze ingestion, or use of aspirin to treat your cat). The history you provide may give your veterinarian clues as to which organs are causing secondary symptoms. If – or when – your kitty is able to adjust to two meals a day, these really strong hunger pangs can reduce or eliminate hairballs, as “indigestible solids” are the last thing to be pushed out of the stomach. Those really strong hunger pangs do the job really well.

And the body requires a healthy population of good bacteria to mount a strong immune response. Eating this rotted meat is one way of acquiring the good bacteria, even though most is destroyed by the low stomach acid pH. It is not the actual bacteria that make humans sick from rotten meat. It is the ingestion of toxins previously produced by the bacteria in the rotting meat and then absorbed into the blood stream causing vomiting and diarrhoea as well as fever and weakness.

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 (relative to the level of meat protein). 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 spp, clostridia, campylobacter and E Coli.

Its release is stimulated by gastrin and acetylcholine and inhibited by somatostatin. Gastric acid production is regulated by both the autonomic nervous system and several hormones.

As the pH drops back in to the 2-3 range , G cells slow their release of gastrin. G-cells also release gastrin in response to certain foods – including peptides, amino acides, calcium, and for people certain elements in coffee, wine and beer ! Gastrin has many functions – also stimulating acid release indirectly by signalling ECL cells to secrete histamine. The histamine binds to H2 receptors turning on the acid release pumps. Gastrin also controls the muscular actions of the stomach, gastrin reduces stomach motility, which slows gastric emptying which helps the stomach hold and process a large meal.

However, note that this is still a fraction of the 24 to 72 hours that full digestion typically takes from start to finish. The fundus plays an important role, because it stores both undigested food and gases that are released during the process of chemical digestion.

All in all not a good result. Also matched to this highly carnivorous (raw meat) diet is a very effective digestive process, which occurs in a relatively short gastrointestinal tract. Dogs and cats have a significantly shorter GI tract compared to other non-meat eating (herbivorous) animals, whereas man has an intermediate length. The relative length of the gut reflects that nature of the diet, and how efficiently or slowly the food is broken down and absorbed.

When feeding homemade food, this is rarely the result of eating too quickly, which is often suggested as the cause. Bacterial flora concurrent with Helicobacter pylori in the stomach of patients with upper gastrointestinal diseases . We demonstrate that stomach acidity increases with the risk of food-borne pathogen exposure and propose that the stomach plays a significant role as an ecological filter and thus a strong selection factor in gut microbial community structure and primate evolution in particular. In light of modern lifestyle changes in diet, hygiene and medical interventions that alter stomach pH, we suggest that stomach acidity in humans is a double-edged sword. On one hand, the high acidity of the human stomach prevents pathogen exposure but it also decreases the likelihood of recolonization by beneficial microbes if and when they go missing.

Your dog’s or cat’s stomach is highly acidic, with a pH range of 1-2.5. Nothing much can survive that acidic environment – it exists to keep your pet safe from potentially contaminated raw meat and other consumables. If you prepare a homemade raw diet for your dog or cat, you don’t include guts. Do not feed the stomach and small and large intestines. Those are the parts of the prey we get rid of, because those are the parts that harbor parasites.

ATPase molecules are probably located at this site to generate energy for motility or cell wall synthesis [1]. Pairing with an integrative or holistic vet who weighs the use chemicals against the overall well-being of your dog or cat is a really important step for your pet’s long-term health. Fortunately, there are lots of effective natural helicobacter treatments.

Veterinarians have also hypothesized the possibility of a hiatal hernia being one underlying cause, as this hernia causes a tear in the feline’s diaphragm. Anesthesia is known to cause acid reflux in felines for a period of time following surgery, but this form of acid reflux is usually temporary and resolves on its own with time. The mucosal barrier protects the stomach from self-digestion. It includes a thick coating of bicarbonate-rich mucus; the mucus is physically protective, and bicarbonate neutralizes gastric acid. Epithelial cells meet at tight junctions, which block gastric juice from penetrating the underlying tissue layers, and stem cells quickly replace sloughed off epithelial mucosal cells.

Stomach acid dissolves and denatures proteins in the meat. The digested food bits are released in a gradual manner into the small intestine. There, enzymes from a cat’s liver and pancreas convert fat into fatty acid, and protein into amino acid. Only a small amount of carbohydrates are digested. Consider taking steps to improve your pet’s diet.

Acid reflux can affect cats of any breed, any sex or age, although acid reflux has been reported in more young cats than older felines. Felines that eat table scraps or have a diet that constantly changes are more prone to developing acid reflux than a feline that is fed a properly balanced diet. Acid reflux is also found in felines that are diagnosed with chronic vomiting and hairballs.

Gastric acidity is likely a key factor shaping the diversity and composition of microbial communities found in the vertebrate gut. We conducted a systematic review to test the hypothesis that a key role of the vertebrate stomach is to maintain the gut microbial community by filtering out novel microbial taxa before they pass into the intestines. We propose that species feeding either on carrion or on organisms that are close phylogenetic relatives should require the most restrictive filter (measured as high stomach acidity) as protection from foreign microbes. Conversely, species feeding on a lower trophic level or on food that is distantly related to them (e.g. herbivores) should require the least restrictive filter, as the risk of pathogen exposure is lower.
