Beneficial bacteria is the gut are known to attack pathogens, manufacture B and K vitamins and even act as anti-cancer agents.
New research appearing in the journal Cell strengthens the recent scientific understanding that the microbes that live in your gut may affect what goes on in your brain. It is also the first to show that a specific probiotic may be capable of reversing autism-like behaviors.
Researchers have long suggested a link between the gut - brain axis and neuropsychiatric disorders such as autism, depression, and eating disorders.
The gut contains microorganisms that
share a structural similarity with the neuropeptides involved in
regulating behavior, mood, and emotion - a phenomenon known as
molecular mimicry. The body can't tell the difference between
the structure of these mimics and its own cells, so antibodies
could end up attacking both, potentially altering the physiology
of the gut - brain axis.
If harmful bacteria dominate the intestines, essential vitamins and enzymes are not produced and the level of harmful substances rises leading to cancer, liver and kidney disease, hypertension, arteriosclerosis and abnormal immunity.
Harmful bacteria can proliferate under many different circumstances including,
The study not causally link microorganisms to autism, but rather emphasizes a correlation between specific bacteria and ongoing symptoms and methods of addressing a possible reversal in those symptoms.
The study underscores the importance of the work being undertaken by the newly formed Autism Microbiome Consortium, which includes Rob Knight as well as commentary co-authors Jack Gilbert of the University of Chicago and Rosa Krajmalnik-Brown of Arizona State University.
The interdisciplinary consortium -
which taps experts in a range of disciplines from psychology to
epidemiology - is investigating the autism-gut microbiome link. For the new Cell study, led by Elaine Hsiao of the California Institute of Technology, the researchers used a technique called maternal immune activation in pregnant mice to induce autism-like behavior and neurology in their offspring.
The researchers found that the gut
microbial community of the offspring differed markedly compared
with a control group of mice. When the mice with autism-like
symptoms were fed Bacteriodes fragilis, a microbe known
to bolster the immune system, the aberrant behaviors were
reduced.
Work published in Environmental Microbiology shows that important gut bacteria travels from mother to child through breast milk to colonize a child's own gut, helping his or her immune system to mature.
Scientific evidence is mounting that the trillions of microbes that call the human body home can influence our gut-linked health.
But more recently, researchers are discovering that gut microbes also may affect neurology, possibly impacting a person’s cognition, emotions and mental health, said Knight, also a Howard Hughes Medical Institute Early Career Scientist and an investigator at CU-Boulder’s BioFrontiers Institute.
The Autism Microbiome Consortium hopes to broaden this understanding by further studying the microbial community of autistic people, who tend to suffer from more gastrointestinal problems than the general public.
People with autism spectrum disorder who would like to have their gut microbes sequenced can do so now through the American Gut Project, a crowdfunded research effort led by Knight.
Benefits of Probiotics
The following are the most well documented benefits of taking probiotics regularly:
Probiotic Sources
Cultured dairy products like,
...are the best known food sources of friendly bacteria.
Equally effective probiotic food sources include cultured/fermented vegetables (cabbage, turnips, eggplant, cucumbers, onions, squash, and carrots). Other, lesser known or used food sources of probiotics are sauerkraut and sourdough breads.
Ideally, one could get a good supply of probiotics from one or more of these diverse foodstuffs. If dietary sources are not easily available, supplemental probiotic powders and capsules are good alternatives.
Choose a brand that
has at least 3 different strains of friendly bacteria
and between 6 - 15 billion live organisms.
