Microbiome Prescription uses over a million rules to generate suggestions on improving the microbiome and hopefully reduce or moderate autism behavior. All of the sources of the rules are studies on the US National Library of Medicine. Microbiome Prescription also can provide the complete evidence trail for every suggestion! That is, where — precisely– is all of the information coming from — none of it is private personal opinion or speculation.
An older post on Validation may be worth reading. Also see Cross Validation of AI Suggestions for Nonalcoholic Fatty Liver Disease
Cross Validation
Cross validation is the process of taking one set of information to generate forecasts or suggestions and then look at a totally independent source of information to see if the forecasts and suggestions are valid, reasonable, and appear to help individuals with the condition. I have done that for several conditions with very good results. NOTE: Everything is generated by code — code that I prefer to improve or correct. I have no personal stake in the suggestion, nothing to defend.
Source of Suggestions
Simple, Candidates which is based on bacteria shifts reported from studies for autism: Taxons. These two links are on the Medical Conditions with Microbiome Shifts from US National Library of Medicine page
The process is simple: some items may have been tests in trials for autism, some have not. If it has been tried, we see what the result in and provide a link to the study (open data!! no “trust me, I am an expert” hype)

- Identification of urinary metabolites that correlate with clinical improvements in children with autism treated with sulforaphane from broccoli. [2018]
- #13 lactobacillus acidophilus

- #14 lactobacillus paracasei (probiotics)
- #15 purple sweet potatoes –
- #16 lactose — Questionable for a subset
- Genetic predictors of celiac disease, lactose intolerance, and vitamin D function and presence of peptide morphins in urine of children with neurodevelopmental disorders [2019]
- Intestinal disaccharidase activity in patients with autism: effect of age, gender, and intestinal inflammation [2011] ” Lactase deficiency not associated with intestinal inflammation or injury is common in autistic children and may contribute to abdominal discomfort, pain and observed aberrant behavior. Most autistic children with lactose intolerance are not identified by clinical history.”
- #17 resistant maltodextrin – no information
- #18 chondrus crispus (red sea weed) – no information
- #19 Conjugated Linoleic Acid
- #20 green tea
- Amelioration of behavioral aberrations and oxidative markers by green tea extract in valproate induced autism in animals [2011]
- The green tea polyphenol epigallocatechin-3-gallate (EGCG) restores CDKL5-dependent synaptic defects in vitro and in vivo [2020] “CDKL5 deficiency disorder (CDD) is a rare X-linked neurodevelopmental disorder that is characterised by early-onset seizures, intellectual disability, gross motor impairment, and autistic-like features. “
Score?
- Five items with no information
- Two items with weak information (not PubMed)
- Twelve items with confirmed information (PubMed)
- One item that is complex/questionable – depends on the child’s DNA
The goal / objective of Microbiome Prescription is to make suggestions that are more likely to help than to hurt. That goal seems to be accompanied. A secondary goal is to suggest items that have not been studied but modelling suggests that it may be of benefit to try. We have 5 such items above.
Remember these are GENERIC Suggestions for GENERIC Autism
The results of an individuals microbiome will be different — there are many variants and subsets for Autism. Each variant will tend towards their own set of variations for the microbiome. Using an individual’s microbiome sample will get suggestions unique for them.
Postscript – and Reminder
I am not a licensed medical professional and there are strict laws where I live about “appearing to practice medicine”. I am safe when it is “academic models” and I keep to the language of science, especially statistics. I am not safe when the explanations have possible overtones of advising a patient instead of presenting data to be evaluated by a medical professional before implementing.
I cannot tell people what they should take or not take. I can inform people items that have better odds of improving their microbiome as a results on numeric calculations. I am a trained experienced statistician with appropriate degrees and professional memberships. All suggestions should be reviewed by your medical professional before starting.
The answers above describe my logic and thinking and is not intended to give advice to this person or any one. Always review with your knowledgeable medical professional.
