SCD for autism information

[Guest guest]

links below but this is the basic science of SCD ...the group is below too...

When the balance in the gut is disturbed, an overgrowth of intestinal flora can result. Microbes migrate to the small intestine and stomach, inhibiting digestion and competing for nutrients. The gut then becomes overloaded with the byproducts of their digestion. This bacterial overgrowth can be triggered by overuse of antacids, reduced stomach acidity due to aging, weakening of the immune system through malnutrition or poor diet, and alteration of the microbial environment through antibiotic therapy.

The components of our diet, particularly carbohydrates, play an enormous role in influencing the type and number of our intestinal flora. When carbohydrates are not fully digested and absorbed, they remain in our gut, and become nutrition for the microbes we host. The microbes themselves must digest these unused carbohydrates, and they do this through the process of fermentation. The waste products of fermentation are gases, such as methane, carbon dioxide & hydrogen, and both lactic & acetic acids, as well as toxins. All serve to irritate and damage the gut. There is evidence that increased acidity in the gut due to malabsorption and fermentation of carbohydrates, may lead common harmless intestinal bacteria to mutate into more harmful ones. Further, lactic acid produced during the fermentation process has been implicated in the abnormal brain function and behaviour sometimes associated with intestinal disorders. The overgrowth of bacteria into the small intestine triggers a worsening cycle of gas and acid production, which further inhibits absorption and leads to yet more harmful byproducts of fermentation. The enzymes on the surface of the small intestines are destroyed by the now present bacteria, and this further disrupts the digestion and absorption of carbohydrates, leading to further bacterial overgrowth. As both the microbial flora and their byproducts damage the mucosal layer of the small intestine, it is provoked to produce excessive protective mucus, which further inhibits digestion and absorption.

Damage to the mucosal layer involves injury to the microvilli of our absorptive cells. These microvilli act as the last barrier between the nutrition we take in and our bloodstream. As our absorption is inhibited, folic acid and vitamin B12 deficiency can lead to impaired development of microvilli, while an abnormally thick layer of mucus prevents contact between microvilli enzymes and the carbohydrates we ingest. The small intestine responds to this spiraling irritation by producing more goblet (mucus-making) cells, creating yet more mucus. Finally, as the goblet cells become exhausted, the intestinal surface is laid bare, and is further damaged, and possibly ulcerated. As more carbohydrates are left in the gut, they cause water and nutrients to be pulled from the body into the colon, resulting in chronic diarrhea. Absorption is further hindered as diarrhea increases the rate with which food travels through the gut.

The starches in all grains, corn, and potatoes must be strictly avoided. Corn syrup is also excluded since it contains a mixture of 'short-chain' starches

specifically selected carbohydrates, requiring minimal digestive processes, are well absorbed and leave virtually none to be used for furthering microbial overgrowth in the intestine. As the microbial population decreases due to lack of food, its harmful byproducts also decrease, freeing the intestinal surface of injurious substances. No longer needing protection, the mucus-producing cells stop producing excessive mucus, and carbohydrate digestion is improved. Malabsorption is replaced by absorption. As the individual absorbs energy and nutrients, all the cells in the body are properly nourished, including the cells of the immune system, which then can assist in overcoming the microbial invasion." The simpler the structure of the carbohydrate, the more easily the body digests and absorbs it. Monosaccharides (single molecules of glucose, fructose, or galactose) require no splitting by digestive enzymes in order to be absorbed by the body. These are the sugars we rely on in the diet. They include those found in fruits, honey, some vegetables, and in yoghurt.

Legal, ilegal food lists from SCD that you can check the knowledge base for why they are ilegal, but the SCD diet is an adult diet for celiacs and doesn't address the phenol, histamines and some other issues like food allergies with these kids but is a good baseline to use.

not ASD but just to show how carbs affect the brain if not digested properly in other circustances where the gut may be affected.

Perlmutter DH, Boyle JT, Campos JM, Egler JM, Watkins JB.Acidosis caused by intestinal bacterial D-lactate production occurs in ruminants engorged with carbohydrate. A similar phenomenon was identified in two children who developed recurrent episodes of metabolic acidosis and peculiar neurologic symptoms in response to increased dietary carbohydrate after major small bowel resections. Both children were found to have elevated plasma concentrations of D-lactic acid at the time of each episode. Acid base and neurologic abnormalities responded immediately to neomycin therapy. Among a number of microorganisms isolated from stool cultures of these patients, one anaerobic Lactobacillus acidophilus species produced large amounts of D-lactate in vitro. Reduction in carbohydrate intake in one patient tested led to a fall in D-lactate generation. We believe that excessive D-lactate production by intestinal bacteria, from malabsorbed carbohydrate, may produce metabolic acidosis and neurologic symptoms in children with small bowel resection
